At the turn of the spring and summer of 1945, intelligence worker Song Zhuowen successfully sneaked into the Harbin Secret Service of the puppet Manchukuo.Song Zhuowen's extraordinary reasoning ability and comprehensive and meticulous style won the appreciation of his superiors. At the same time, he also attracted the jealousy and secret strife of his colleagues.In order to find out where the arrested members of our party were secretly detained, Song Zhuowen took advantage of his familiarity with the work process to follow the clues, find the secret detention point, and rescued the underground party members.Several operations of the Secret Service were frustrated one after another. Guan Xue, the chief of the Secret Service, believed that there was an insider and began to investigate.Song Zhuowen successfully got rid of suspicion by taking advantage of the complex interpersonal relationships within the secret service.He continued to fight in dangerous environments, resolved crises many times, and completed many difficult tasks such as obtaining the enemy's garrison patrol route map.However, he was exposed after obtaining intelligence on a secret weapon being developed by the Japanese army. He was shot and fell to the ground during the retreat. The organization successfully rescued him and covered him out of Harbin.

A seriously injured woman staggered to find an underground party boss, and all the codes were correct.Lao Duan hurriedly took the woman home. When he was about to hand over the information, Lao Duan discovered that the woman did not look like someone who came down from the mountain. She should be a Puppet Manchukuo agent. Zhuo Wen, who was just outside, fired a warning shot.So Lao Duan hid the information and prepared to escape, but was caught by the agents.And this woman who pretended to be seriously injured was Guan Xue, the chief of the Harbin Secret Service Section.​

In the torture room of the Harbin Police Department's Special Agents Section, Guan Xue, the chief of the Special Agents Section, was severely torturing the underground party member Lao Duan, but found nothing. Guan Xue then called an acupuncture doctor, Dr. Shi, and asked him to use acupuncture to make him miserable and unable to survive.To force him to speak, Dr. Shi observed and reported to Guan Xue that the man was now in critical condition and might not be able to survive the process. Guan Xue said that he would rather kill him by mistake than let him go. Dr. Shi started giving the injection after receiving the order., Sure enough, not long after, Lao Duan stopped breathing and pulse during acupuncture.

Guan Xue had no choice but to give up.It turns out that the acupuncture doctor Dr. Shi was also a comrade of our party. He rescued Lao Duan through this method, took Lao Duan away from the mass grave, and then used acupuncture to revive him.Guan Xue realized too late that there might be a problem and ordered a city-wide manhunt.Lao Duan asked Doctor Shi to quickly hand over a pipe containing information. The meeting place was on the train station platform, and told him the characteristics and password of the contact person.

In the evening, Song Zhuowen came to the railway to look for information and was discovered by Guan Xue and Pan Yue.Song Zhuowen lied and claimed that he was looking for the thief's dirt.Pan Yue searched Song Zhuowen and found no information.​

The next day, Xie Yue, a flower seller in the square, was bullied by the Japanese. Song Zhuowen came forward to intercede, but the Japanese did not take her seriously. Later, Song Zhuowen's boss, police officer Sa Watanabe, came to help Xie Yue., but Song Zhuowen soon realized that Watanabe had other plans. Sure enough, he tracked and found that Watanabe led Xie Yue to a warehouse to commit an invasion. Zhuowen was in a hurry and killed the Japanese police officer Watanabe with Xie Yue.​

Guan Xue wants to treat Zhuo Wen to dinner.After Zhuo Wen found Lao Qian, he reported the intelligence handover process, saying that the intelligence was not handed over smoothly, but it was not obtained by the Secret Service Division. He also informed that Guan Xue mistook him for his twin brother.

Zhuo Wen believes that this is his only chance to break into the Secret Service.At the dinner party that night, Zhuo Wen almost didn't recognize Guan Kai, who had escaped with Zhuo Wu in the past.He is Guan Xue's younger brother.After the dinner, Zhuo Wen followed the people from the Secret Service to the murder scene of Watanabe.Zhuo Wen analyzed some details of the case at the scene and was appreciated by Guan Xue.Guan Xue invited Zhuo Wen to come to the Secret Service Section.

After Song Zhuowen entered the Secret Service Section, he was always provoked by Hu Bin. Whether he was assembling firearms or fighting, he always suffered.Zhuo Wen said that he rarely fired guns in the police force, and everyone was unconvinced by his remarks.

Pan Yue arranged for three people (Song Zhuowen, Tian Xiaojiang, and Ding Peng) to interrogate the acupuncture doctor Dr. Shi on the pretext of training new people. He judged that if there was an underground party, they would definitely use this opportunity to contact Dr. Shi. Song Zhuowen almost fell into the trap., fortunately, it was judged in time that this was a trap, and finally the trick was used without any flaws.

The Secret Service found clues about Dr. Shi's wife, who was a mother who had just given birth. Guan Xue ordered to find her quickly. Zhuo Wen followed Tian Xiaojiang in the name of wanting to make a meritorious service; in the hospital, Pan Yue was conducting a strict search.We are about to find Dr. Shi's wife.

When Song Zhuowen was in danger, he used Tian Xiaojiang to make a trick, and cooperated with Lao Qian inside and outside, so that Guan Xue completely locked the suspicion on Tian Xiaojiang and safely transferred Dr. Shi's wife and children.Tian Xiaojiang was dying in prison, saying that there was something wrong with Zhuowen's pen and it was the murder weapon that killed Watanabe.But Zhuo Wen had already solved this flaw in advance.

Tian Xiaojiang no longer had the means to resist, and was beaten into submission in the Secret Service Section. Guan Xue identified him as the underground party member who had infiltrated the Secret Service Section as shown in the intelligence. Tian Xiaojiang was quickly taken away by the Japanese, and Song Zhuowen's suspicion was lifted., and also gained further trust from Guan Xue.Guan Xue invited Song Zhuowen to eat at home. Although Zhuowen had not had time to complete the memory puzzle, he had to go.

Sure enough, at the dinner table, Guan Xue said mysteriously that the dish cooked today was Zhuo Wen's favorite dish. Song Zhuowen did not answer this question perfectly, and Guan Xue was surprised.

Song Zhuowen knew that similar problems would follow in the future.Song Zhuowen conveyed the news to Dr. Shi in the interrogation room that Dr. Shi's wife and children had been safely transferred. Dr. Shi was deeply comforted after learning the news. He knew that it would be difficult to get out of the Special Service Department alive. In order to avoid involving other comrades, he prepared toSacrificing himself, he told Song Zhuowen before he died that there might be another person (a man in a suit) who took the information at the train station. Song Zhuowen could only roughly recall the image of that person through his memories.

Song Zhuowen began to search for clues to find the person who might have obtained the information that day, a man in a suit. Pan Yue, the head of the Intelligence Unit of the Special Service Division, was also searching for clues to investigate. The two followed the clues and raced all the way to find them. They found them almost simultaneously..But Song Zhuowen was finally one step ahead and tracked down the traitor first, and shot him to death after negotiations failed.

Although Zhuo Wen killed the traitor, the cigarette rod containing the information was still found by the people from the Secret Service. They took out the film negatives hidden in it and locked it in the safe by Guan Xue.

Guan Xue's superior, Asano Daigo, who was sent to Harbin by the Japanese military intelligence agency, was assassinated on the way to Harbin, but he did not die. He was injured and admitted to the hospital. Asano Daigo told Guan Xue that this killer may have been in many places many times.One of his assassins was an anti-Japanese activist nicknamed “Manchurian Robin Hood”.

Guan Xue suggested to Asano Daigo that he should release the news that Asano Daigo was going to be discharged from the hospital, so as to lure the anti-Japanese element to show up again and set up an ambush to arrest him. Asano Daigo agreed to this suggestion.Guan Xue also reported the film negatives to Asano Daigo, and Asano Daigo asked Guan Xue to show it to him quickly.

That night, Hu Bin and Pan Yue invited Song Zhuowen to dinner.Song Zhuowen caused some trouble through Xie Yue, who was accompanying the wine at the scene.The dinner ended.Then Song Zhuowen sneaked into Guan Xue's office, and when he was about to try to open the safe to get information, he heard the sound of Guan Xue opening the door with a key.

Song Zhuowen hid behind the curtain and could only watch as Guan Xue took out the film from the safe and handed it to Asano Daigo's adjutant. Fortunately, he was not discovered.After Guan Xue arranged the task of capturing “Manchurian Robin Hood” tomorrow, he asked everyone not to leave the Secret Service Section.

But Pan Yue ran out secretly, saw a doctor, and got some medicine for himself.The next day, the Secret Service set up an ambush near the hospital where Asano Daigo was staying, waiting for the assassin to appear.

As expected, the assassin who had already disguised himself appeared again, preparing to snipe Asano Daigo from a nearby tall building.Just when Guan Xue and others locked the target and prepared to arrest, Song Zhuowen gave the assassin some hints through mirror reflection. After the assassin discovered that there was an ambush, he knew it was a trap, ended the operation early, and successfully left the scene.The Secret Service came up short.

Song Zhuowen felt that this assassin was somewhat familiar, and began to look for clues to analyze the assassin's whereabouts. Finally, he found an uninhabited villa late at night, and sure enough, the assassin was hiding here.

The Secret Service also quickly found this place based on Zhuo Wen's report. When they broke into the villa, they saw Song Zhuowen who had just been attacked and was in a panic. Song Zhuowen told them how he found this place, but it was a pity that the assassin escaped.Guan Xue didn't pursue the matter further, she just asked him not to act rashly and dangerously in the future.

Hu Bin expressed strong dissatisfaction with Song Zhuowen's unauthorized actions, complained that Song Zhuowen had done something bad, and blurted out all kinds of sarcastic remarks, but when he saw that Guan Xue had no other expression, he had to give up, but he once again asked to have a duel with Song Zhuowen..

Song Zhuowen, knowing that he could no longer avoid it, agreed this time.Early the next morning, the two began to compete on the street.To the surprise of everyone present, Song Zhuowen, who had previously seemed incompetent in martial arts, beat Hu Bin until he was unable to parry, and was finally stopped by everyone.

Pan Yue also realized the problem with the clock and immediately went to the villa to check the clock.Zhuo Wen immediately returned to the villa and set the clock before Pan Yue could, eliminating the crisis.On the way Zhuowu retreated, he killed a gangster who bullied the vendor. After investigation, the Secret Service found that the stall owner had met the assassin, Song Zhuowu.

Guan Xue took Song Zhuowen and others there. When Guan Xue asked the stall owner to describe the assassin's face and appearance, the stall owner subconsciously stared at Song Zhuowen, who was standing next to Guan Xue before he could dodge. Everyone also looked at him.Song Zhuowen couldn't help but break out in a cold sweat, but the stall owner's description was completely different from Zhuowen's.​

After returning home, the two brothers began to take stock of all the details of what happened. Song Zhuowu said that on the way back, a young man greeted him and seemed to know him. Song Zhuowen judged that this person was Guan Kai.Song Zhuowu had met Guan Kai when he was a child, but now he no longer recognizes him.Song Zhuowen remembered that if Guan Kai mentioned this matter after returning home, the brothers would reveal their secrets, because Zhuowen was with Guan Xue at that time.

Song Zhuowen went to find Guan Kai urgently. Unexpectedly, Guan Kai also didn't want Guan Xue to know his whereabouts because of some secret, and asked Song Zhuowen not to mention the matter. Song Zhuowen just agreed, and they agreed that the two of them would pretend they had never met.The consensus is that Zhuo Wen is also curious about what Guan Kai's secret is.Song Zhuowu decided to assassinate Guan Xue alone, but after shooting, he missed.

After Zhuo Wu failed to assassinate Guan Xue, Zhuo Wu was punished and tied up by Zhuo Wen.Guan Xue also hid in Lao Jin's place.Asano Daigo came to inspect the Secret Service Section. After Guan Xue reported, he particularly praised Song Zhuowen for his bravery in fighting Manchuria Robin Hood and specifically allowed him to attend the reception held at Asano Daigo's house.​

Hu Bin returned to the Secret Service Department from the hospital, made peace with Zhuo Wen on the surface, and made it clear that Zhuo Wen should come to the action unit.Zhuo Wen doesn't want to move stocks, because if he joins stocks, he will be monitored by Hu Bin and unable to perform tasks.But at the same time I couldn't refuse.

Song Zhuowen knew that attending the reception at Asano Daigo's house would be a good opportunity to obtain the previously lost film negatives. After discussing with Lao Qian, he came up with a plan that required exquisite cooperation between the two brothers.

In the end, although he was almost exposed several times and was surrounded by dangers, he finally managed to get the film negatives with Zhuo Wu's cooperation.Song Zhuowu hid in Guan Xue's car, hijacked Guan Xue and Zhuo Wen, and escaped from Asano Daigo's house.

Guan Xue felt that she had been humiliated. Although she was very angry, she could not tell anyone.Song Zhuowen handed the film obtained from Asano Daigo to Lao Qian, and Lao Qian sent a report to his superiors to send someone to Harbin to pick it up as soon as possible.

While the Secret Service was still trying to review the Asano Daigo family's case to no avail, Song Zhuowen accidentally learned of the existence of Guan Xue's top-secret insider “Squirrel” in the anti-Japanese organization. Zhuowen decided to find out the existence of this squirrel.​

Another Japanese officer was shot dead in Harbin. Guan Xue realized that it might have been done by Guan Kai, because Guan Kai had a special pistol that happened to fire the kind of warhead that killed the Japanese.

Guan Xue returned home and asked Guan Kai to hand over the pistol. Guan Kai bit the pistol and lost it.Guan Xue was very angry but helpless.

Hu Bin came to Guan Kai's house early in the morning and forced Guan Kai to hand over the pistol and bullets.Then he brought the ballistic analysis report and told Guan Xue that it was not Guan Kai's pistol that fired the gun. Guan Xue felt relieved this time.​

Song Zhuowu was sent by Lao Qian to the mountain where the guerrillas were.Before leaving, Zhuo Wu asked Lao Qian to protect Zhuo Wen.​

Guan Xue once again obtained important information through the mole placed in the Anti-League, which showed that the Anti-League would send a liaison officer to Harbin to contact the underground party.The arrangement between Lao Qian and the liaison officer failed. Our party liaison officer was taken to a safe house in the Secret Service Department by Guan Xue. The situation was urgent.

Our party also captured a Japanese spy.Song Zhuowen found the location of this safe house after careful observation and deliberation.

After going through many dangerous twists and turns, the liaison officer was successfully rescued.However, due to Xiao Wei's negligence, one of the Japanese and puppet agents in his custody escaped.Guan Xue was furious because the liaison officer was rescued from the safe house. Pan Yue suddenly received a call from the escaped traitor agent. The traitor described to her that he saw the pursuer, Song Zhuowu (who failed to leave the city).He came back), who looked like Puke, etc. Just as everyone was staring at Song Zhuowen, gunshots were heard on the phone.

When Guan Xue and others rushed to rescue the traitor, they arrived at the scene and found that the man had been killed and the murderer had already left.It turned out that fortunately Song Zhuowu returned in time and solved the traitor.

Lao Qian asked Song Zhuowen to find a way to send the liaison officer and the film out of the city immediately. However, at this time, the Secret Service had laid a dragnet at all exits in the city and set up numerous barriers. It was very difficult to send people out of the city.

After Song Zhuowen looked at Zhuowu for a while, he came up with a way. He took advantage of the loopholes in the shift change time of the checkpoint personnel, and finally asked Song Zhuowu to drive out of the city with the liaison officer and the film.

However, Cui Anping, the shift leader, discovered that the vehicles leaving the city did not return to the city on time. He discovered that something was fishy and did not change with the next shift.Because he discovered that there were two Song Zhuowen, one was in the city and the other was out of the city, he vaguely guessed that Song Zhuowen might have twin brothers.

Zhuo Wu went up the mountain to find the guerrillas and handed the film to the organization.Political Commissar Zhou on the mountain asked Zhuo Wu to stay on the mountain and not run around.Guan Xue encountered an assassination attempt by a military commander on her way to work, which made Guan Xue and the bodyguards around her very nervous and sensitive.​

The Secret Service Department conducted a physical examination. During the activity, Zhuo Wen discovered that Pan Yue did not dare to undergo a physical examination and seemed to be hiding his health.Song Zhuowen received a call from Cui Anping. Cui Anping told him that he had discovered his secret and asked him for 500 Manchurian coupons, otherwise he would be reported to the Secret Service immediately.

Song Zhuowen was shocked, but he was also glad that Cui Anping was a money-grubber. In order to stabilize Cui Anping, he first gave him money as required. This made Cui Anping even more sure that his guess was accurate and held Song Zhuowen's hand.handle, ecstatic.

Soon Cui Anping called Song Zhuowen again and asked for ten gold bars, and only gave him a maximum of three days.Zhuo Wu couldn't bear it anymore and went down the mountain privately, and deliberately walked into a small inn. In the inn, Zhuo Wuli was drugged and tied up by the waiter.

Just when the innkeeper was about to torture him, Song Zhuowu suddenly broke free, killed the waiter instead, and captured the innkeeper alive. It turned out that Song Zhuowu, who had traveled around the world for many years, had already judged that this was not a simple inn.After interrogating the shopkeeper, it was confirmed that this inn was a traitor's lair.The mission is to exchange information alone with the mole lurking in the anti-alliance team on the mountain.​

Zhuo Wu followed the clues, found the radio station and killed the spy Qiao Er.In Harbin, the greedy Cui Anping not only blackmailed Song Zhuowen, but also secretly called Guan Xue, asking for a large sum of money in the name of providing a list of underground parties lurking in the Secret Service. Guan Xue agreed to him.

Cui Anping knew that he had been discovered by Zhuo Wen, so he led his men to treat Zhuo Wen to a meal. At the banquet, they talked about Zhuo Wen's two trips out of the city.Zhuo Wen knew that Cui Anping was warning him that if Cui Anping was silenced, his men would definitely tell the police about Zhuo Wen's two trips out of the city, and Zhuo Wen would be at risk of being exposed.

Soon Cui Anping called Song Zhuowen again and asked for ten gold bars, and only gave him a maximum of three days.​

Zhuo Wu couldn't bear it anymore and went down the mountain privately, and deliberately walked into a small inn.

Guan Xue agreed to him.Cui Anping knew that he had been discovered by Zhuo Wen, so he led his men to treat Zhuo Wen to a meal. At the banquet, they talked about Zhuo Wen's two trips out of the city.

Zhuo Wen knew that Cui Anping was warning him that if Cui Anping was silenced, his men would definitely tell the police about Zhuo Wen's two trips out of the city, and Zhuo Wen would be at risk of being exposed.

After the agents killed Cui Anping, they began to investigate Cui Anping's men.But Zhuo Wen had already vaccinated Cui Anping's men. In order to prevent themselves from being implicated by Cui Anping, Cui Anping's men didn't know anything about the agents.​

An explosion occurred in Harbin. Zhuo Wen and Pan Yue analyzed that it was caused by the failure of the anti-Japanese organization to make explosives.Zhuo Wen led the agents to follow the clues to the warehouse where the anti-Japanese organization was hiding.Hu Bin asked Zhuo Wen to rush in, but Zhuo Wen deliberately disobeyed in order to protect the anti-Japanese elements inside.No one expected that the warehouse turned out to be a trap, and the agents who rushed in were injured one after another.​

Many agents went to the hospital for treatment. Zhuo Wen was punished for being timid in the face of battle and was sent to the hospital to accompany the wounded.Guan Xue and Asano Daigo also came to the hospital to visit the wounded.

On the day of the operation, Guan Kai, who had been worried about his sister's safety, discovered that the bomb was installed under Guan Xue's car. He thought that his comrades had made a mistake, but the answer he received was that the operation could not be cancelled, and he was told that the operation could not be canceled.It was a good opportunity for him to prove himself. Realizing that he was deceived, Guan Kai was in great pain, but he also thought that this might be an opportunity for relief. He got into Guan Xue's car and decided to die with his sister.

Song Zhuowen, who had been in the hospital, found that Guan Kai was very unusual today. At first, he followed and observed for a while but found nothing unusual. But in the end, from the look in Guan Kai's eyes and the words he said to him when he got in the car, he quickly flashed back and sorted out various clues from the past.Realized the bomb under Guan Xue's car.

Song Zhuowen hurriedly drove out to chase Guan Xue's car, stopped it, and took out a time bomb from under the car. It was about to explode. At this moment, he was in the city, surrounded by elementary school students who had just finished school. Song Zhuowen could only hold the bomb.Run wildly.​

At the critical moment, Song Zhuowen decisively threw the bomb into a well on the roadside. The explosion was powerful, but fortunately no innocent casualties were caused.Guan Xue also managed to escape death, and Song Zhuowen saved her life.

In Asano Daigo's office, Song Zhuowen told Asano Daigo and Guan Xue in detail his ideas for discovering and eliminating bombs. Of course, he did not mention Guan Kai at all.Asano Daigo admired Song Zhuowen's ability to do things and immediately promoted Song Zhuowen to deputy chief of the intelligence team.

During Pan Yue's interrogation of Guan Kai, Zhuo Wen worked hard to exonerate Guan Kai and help him get rid of suspicion.But Guan Xue was still able to realize the truth of the matter. Guan Xue was very sad that her brother wanted to kill her.​

Pan Yue was responsible for reporting the explosion to Asano Daigo, but for some reason, he had been out of shape since he left home in the morning.When he arrived in front of Asano Daigo, the report was even more confusing, even involving Guan Kai, which made Guan Xue very angry.

Pan Yue's abnormal state continued, so much so that it seriously affected his work. Guan Xuene was furious and sent him to the hospital, suspending his work.Pan Yue was sent to the special ward of the mental hospital. He knew that he had been plotted by Song Zhuowen this time, and vowed to take revenge and expose Song Zhuowen's identity.

He first used the relationships he had accumulated over the years at work to help doctors and nurses in the hospital solve practical problems and win over many medical staff. Then he brought in Ding Peng to coerce and induce him, controlled Ding Peng, and asked Ding Peng to report to him in a timely manner.Report the movements of the Secret Service Section and Song Zhuowen.​

Guan Xue found Xie Yue and told Xie Yue that she had obtained evidence that she had killed Sheriff Watanabe, and asked Xie Yue to follow her command and monitor Song Zhuowen.Song Zhuowu also returned to Harbin from the Anti-League Mountains, and told Lao Qian and Zhuo Wen that the spy planted by Guan Xue on the mountains was still there.

After Pan Yue resigned, the position of chief of the intelligence unit became vacant, and it made sense for Song Zhuowen to take over as chief.Before promoting Zhuo Wen to head of the Intelligence Unit, Pan Yue mobilized his connections in the review department to conduct a more thorough investigation of Zhuo Wen.

The investigation department sent people to Fengtian, Song Zhuowen's hometown, to investigate.At the same time, he found a reason to place Zhuo Wen under house arrest, preventing him from leaving the Secret Service Building.Zhuo Wen, who was aware of it in advance, sent a message to Lao Qian before being placed under house arrest, informing Lao Qian that Guan Xue might send someone to his hometown in Fengtian to investigate.

Time was urgent, so Lao Qian immediately sent Zhuo Wu and other comrades to rush back to his hometown to make arrangements before Guan Xue's people.Song Zhuowu arrived at his hometown in advance to make arrangements and made a fake family photo without twins in it.

Pan Yue asked Ding Peng to send the photo to the photo agency for appraisal and handed it over to the director of the photo agency.

Just when the director of the photo agency was about to verify the authenticity of the photo, Song Zhuowu, who arrived, found a way to change the photo's package, and put another family photo of someone else's family taken from the photo studio into the file bag.​

After identification, the results showed that the photos were genuine, and the Secret Service personnel went back to report to Guan Xue that the photos were genuine.The censorship department lifted Song Zhuowen from house arrest.Song Zhuowu found Zhuo Wen and told him that the photos in the file bag were not family portraits of their family. Guan Xue would open it at any time. Once opened, Zhuo Wen's identity would be exposed, so Zhuo Wen was told not to return to the Secret Service Section, but to leave the Secret Service Section and fly away.

Song Zhuowen didn't want to give up easily, and decided to continue lurking after making a judgment.He managed to exchange the photo in the file bag in Guan Xue's office, and this time the identity crisis was finally resolved.Guan Xue made Song Zhuowen the chief of the intelligence unit.

Pan Yue was furious after hearing the news in the hospital.Xie Yue was excluded in school because she knew Zhuo Wen, so Zhuo Wen had to take Xie Yue home to live.​

After becoming the head of the Intelligence Unit, his authority was completely different. Song Zhuowen successively provided a large amount of useful intelligence for the anti-Japanese work.

Lao Qian conveyed the latest important instructions from his superiors to Song Zhuowen, asking Zhuowen to find a way to draw a detailed weapons and firepower configuration map of the Dongning Fortress on the Manchu-Soviet border.

Because of the last hospital bomb incident, Guan Kai had a view on the military reunification agents and wanted to alienate the agent Mr. Ning.However, he was entangled by military special agents and even killed a classmate who disagreed with Guan Kai, making Guan Kai's situation difficult. Guan Kai had to find Song Zhuowen and ask for help.

After receiving Guan Kai's request for help, Song Zhuowen began to search for military reunification agents. Since they were both anti-Japanese forces, Zhuowen could not expose them, but he hoped to help Guan Kai get out of the entanglement.

At the same time, Song Zhuowen used the abandoned military stronghold and used the remaining documents to create the illusion of a leak of secrets from Dongning Fortress, reported it to Guan Xue and Asano Daigo, and applied for an investigation by the Intelligence Unit.​

Zhuo Wen begged Guan Xue and arranged a transfer place for Xie Yue to study in Guan Kai's school.

The original plan was that the Japanese army would send a special envoy from Xinjing to Dongning to investigate. This person had been instigated by our party to rebel. Song Zhuowen's task was to contact him after he arrived in Harbin and hand him the tools needed to complete the task.But this man was timid in the face of battle and did not dare to go.

Song Zhuowen decided to go to Dongning in place of the special envoy, so he asked Guan Xue to quickly injure the envoy (Guan Xue agreed in order for the Secret Service to intervene in this mission), and went to the fortress instead of the envoy.

Asano Daigo and Guan Xue agreed to this plan for their own interests.After Song Zhuowen arrived in Dongning, he began to carry out the mission. Although it was difficult and dangerous, the progress was relatively smooth, and he discovered Japan's even greater ulterior secrets hidden in the fortress.​

Song Zhuowen, acting as a special envoy in Dongning Fortress, was investigating the leaker while performing a drawing task. In the end, the investigation came to an end and the leaker was not found, so he was ready to return.

Note-taking experts and Zhuo Wen returned to Harbin on an arranged special plane. On the plane, Zhuo Wen's identity was exposed. Zhuo Wen had a gunfight with them. The captain was also injured in the process. The plane lost control and rushed to the ground.

When the Secret Service arrived at the scene of the plane's execution, they found nothing but charcoal and no valuable clues.

Zhuo Wu was extremely sad and angry when he learned that Zhuo Wen had sacrificed. He decided to end it all with a vigorous explosion. Lao Qian finally stopped Zhuo Wu.Hu Bin wanted to rape Guan Xue, but Guan Xue pulled out a gun and drove Hu Bin away.​

Zhuo Wen was still alive and rushed back to Harbin overnight and handed the information to Lao Qian.After Zhuo Wen came back, everyone was very happy.Japanese spies began to raid the strongholds of our underground party with greater intensity. He Shan was exposed and began to move under the command of Lao Qian.

After Song Zhuowen returned to the Secret Service Section, he began to tame Pan Yue's men to do things for him.What Lao Qian didn't expect was that He Shan was targeted by spies while watching a movie and was quickly arrested by Hu Bin.Song Zhuowen tried to find a way to rescue He Shan, but he didn't expect that He Shan had rebelled under severe torture and almost exposed Song Zhuowen's identity.

Liaison officer He Shan provided the time and place where Xia Tao and Lao Qian were going to meet. Guan Xue began to arrange the arrest and reported the operation to Asano Daigo. Asano Daigo took it very seriously and sent the Japanese military police to assist in the blockade and support.

Song Zhuowen wanted to tell Lao Qian the news, but it was too late. Lao Qian had already gone to his residence to meet Xia Tao.

Zhuo Wu, who learned Zhuo Wen's information, knew that Lao Qian was in great danger at this moment, so regardless of the risk that Zhuo Wen might appear at the same time, at the critical moment, Zhuo Wu fired a warning shot and allowed Lao Qian to leave the roundup area safely, but XiaThao died.

Song Zhuowu fell into an encirclement, and finally Song Zhuowu, along with other people in the encirclement, were taken away by the Japanese.Song Zhuowu was taken to Unit 731, where he also met Tian Xiaojiang. At this time, Tian Xiaojiang had been tortured by the Japanese and was not like a human being, nor a ghost like a ghost.​

Song Zhuowen discovered through investigation that even the Special Service Section had no news about where Zhuowu was taken.Xie Yue and Guan Kai's squad leader, Long, were also taken away by the Japanese that day.

The father of Classmate Long’s girlfriend Junko is a cadre of Unit 731, but even if Junko begs her father, she cannot save Classmate Long.Xie Yue and Guan Kai discovered the clues and informed Song Zhuowen. They began to follow Junzi secretly.

Song Zhuowu also met Dr. Shi in Unit 731.Although everyone is desperately trying to survive, they are still about to be sent for experiments.Song Zhuowen learned through a Japanese painter that the people detained in 731 were about to be in disaster.​

Xie Yue and Guan Kai kidnapped Junzi. Junzi resisted desperately and recognized Guan Kai and Xie Yue.Just when the two were at a loss, Guan Xue appeared and helped them clean up the mess.​

Lao Qian and others went to 731 to rescue people. On the way, they encountered bombers flying overhead.

731 brought all the Chinese to the experimental site, and the bombers dropped biological and chemical weapons bombs.After the bomb exploded, Chinese people escaped from prison one after another. The process was extremely thrilling. They were soon discovered by the guards. The guards shot and chased them, killing many people.Lao Qian and others were also outside to provide support and opened fire with the guards.​

Song Zhuowen and the people from the Secret Service also came to the experimental site. They received orders to kill all survivors.With the help of Zhuo Wen, Song Zhuowu escaped, but Tian Xiaojiang died.​

After Song Zhuowen returned to the Secret Service Department, he started to have a fever and told Guan Xue the cause of the disease. Guan Xue was shocked and sent Song Zhuowen to the hospital.But the Japanese said that Song Zhuowen was just a Chinese and would not give him an antidote.

Song Zhuowen said that he would be able to trace the whereabouts of the fugitive immediately. After hearing this, Unit 731 brought medicine to Zhuowen to treat his illness.Xie Yue was threatened at school. A classmate named Lu Jianshe followed Xie Yue, discovered Xie Yue's secret, and used it to blackmail Xie Yue.

Asano Daigo began to think of a way to accompany Unit 731 and withdraw to Japan together. He did not want to stay in Manchuria and be killed by the Soviets.

Lu Jianshe and his companions raped Xie Yue. Unexpectedly, Guan Xue came. Guan Xue killed Lu Jianshe's companions and completely tamed Lu Jianshe and Xie Yue.​

Xie Yue continued to monitor Song Zhuowen for Guan Xue, but was discovered by Song Zhuowen.Hu Bin cared about Guan Xue, but happened to bump into Guan Xue who was angry, and was humiliated instead.

Song Zhuowen used a trick to confirm that Xie Yue was the one monitoring him, and made this clear to Guan Xue, who also admitted it.Afterwards, Song Zhuowen still kept Xie Yue by his side.​

Hu Bin found an opportunity to sneak into Guan Kai's bedroom and stole Guan Kai's pistol.After Guan Kai returned home, he found that the gun was missing and asked his sister Guan Xue. Guan Xue guessed that it might be Hu Bin and called Hu Bin to ask. Hu Bin asked her to talk to her the next day. Guan Xue felt that the matter might not be the case.Simple.

At work the next day, Guan Xue called Hu Bin to the office. Hu Bin proposed to Guan Xue again but was rejected. Hu Bin turned over his trump card and told her that Guan Kai was suspected of shooting a Japanese officer and that he had retained all the evidence.

The panicked Guan Xue went home and questioned Guan Kai, and Guan Kai had to admit that it was him.Guan Xue went to Hu Bin again, but Hu Bin was unmoved and said that he only wanted to marry Guan Xue. He had always loved Guan Xue deeply, otherwise even if he died, the evidence of Guan Kai's murder would be sent to Asano Daigo's officeon the table.

Her younger brother Guan Kai is Guan Xue's only relative. She has raised Guan Kai since she was a child. Guan Kai is the only weakness in her heart. Anyone can give up, but Guan Kai cannot.She took the initiative to tell Hu Bin that she would get married the day after tomorrow.​

It turns out that Lao Miao is the mole (squirrel) of the guerrillas in the mountains. He uses carrier pigeons to continue delivering messages to Guan Xue.

Lao Miao was found out by the guerrillas, but the guerrillas did not kill him and kept him for future use when liquidating other spies.Doctor Shi, who fled to the mountains from 731, also began to show symptoms of the plague. He chose to leave the camp by himself and forbade everyone to come to him.​

Song Zhuowen cannot let Hu Bin succeed, Guan Xue may continue to be at his mercy, and Zhuowen's own work in the Secret Service will be difficult to continue, so Hu Bin's thorny position must not be consolidated.

The most important thing now is to find Guan Kai's pistol that Hu Bin stole. Without evidence, he has no money to threaten. Zhuo Wen begins to investigate where Hu Bin may hide the gun.

Just as the wedding ceremony was about to be held, Zhuo Wen used a clever trick to make Hu Bin reveal the location of the gun. Zhuo Wen rushed to the wedding scene and told Guan Xue that the wedding was not completed.

At the Yamato Hotel, Hu Bin asked why he had not kept his pistol, but the Yamato Hotel said that the pistol was always there. At the same time, Xiao Wu led someone to capture Hu Bin.

Hu Bin knew that he had been fooled. Hu Bin used the letter stored in the Yamato Hotel to prove to Guan Xue that in fact, regardless of whether Guan Xue married him or not, he had never planned to harm Guan Xue's siblings, and it was impossible to report Guan Kai. The reason why he did thisHe did it because he really loved her and he couldn't help but want to get her by any means.

Guan Xue looked at the evidence and believed Hu Bin's words, but she didn't love Hu Bin. She expressed her gratitude for his love and hoped to never mention it again.Before Lao Qian was about to return to Harbin, the specific information and date of his trip had been sent to Guan Xue.

Hu Panyue hated Song Zhuowen deeply and wanted to get rid of Song Zhuowen. Both of them continued to investigate everything about Song Zhuowen. Although Pan Yue knew that Guan Xue already trusted Song Zhuowen very much, he still secretly provided a lot of information to Song Zhuowen.Clues that were not conducive to Zhuo Wen were given to Guan Xue. He knew that the suspicious Guan Xue would definitely be touched. Sure enough, these doubts once again aroused Guan Xue's suspicion of Zhuo Wen.

Guan Xue received news from an insider placed within the Anti-Japanese Alliance that the important cadre who had escorted the underground party up the mountain would return to Harbin on the 9th.Guan Xue meditated alone for a long time. She did not notify Song Zhuowen, but quietly ordered the cancellation of Special Agent Corey's vacation.Guan Xue was afraid of arousing Zhuo Wen's suspicion, so she specially arranged another task for him.

The mission to arrest the underground party failed. Although it seemed to have nothing to do with Song Zhuowen on the surface, the shrewd Pan Yue believed that the matter must be related to Zhuowen. After asking Ding Peng to tell him all the details, he noticed a possible loophole.Let Ding Peng follow the clues to find, and sure enough, Ding Peng found Lao Qian's residence according to the instructions. Ding Peng quickly reported it to Guan Xue, who brought people to arrest him. Lao Qian and the Secret Service Department, who had not received any information,The officer opened fire and escaped the blaze but was seriously injured.​

When Zhuo Wu retreated, he accidentally glanced at Guan Xue. Guan Xue was shocked.​

Guan Xue suddenly walked into Song Zhuowen's house to check, but Lao Qian hid in Xie Yue's bathroom and escaped.Guan Xue reprimanded Ding Peng for not reporting the matter earlier. At this time, Pan Yue suddenly appeared and was directly appointed by Asano Daigo as the deputy chief of the Secret Service Section.

Guan Xue felt the crisis. Asano Daigo actually skipped her in appointing Pan Yue this time, which meant that Asano Daigo might not be so satisfied or even trust her.Song Zhuowen felt a huge crisis when he learned about Pan Yue's return.

As the war progressed, the people in the Secret Service began to realize that Japan was about to be defeated, and they all began to find a way out.In order to follow 731 back to his homeland, Asano Daigo even did not hesitate to create false information to deceive the Kwantung Army headquarters.

Pan Yue found Hu Bin. He suggested that Hu Bin transfer staff from other counties to monitor Song Zhuowen, because if Song Zhuowen was an underground party, he would definitely try to treat the seriously injured Lao Qian. Hu Bin accepted his suggestion.

Zhuo Wu pretended to be a spy from another county and beat the Japanese Special High School officials.The senior officials of the Special High School were furious and put away all the real spies who were monitoring Zhuo Wen.Song Zhuowen quickly evacuated to a safe place with Lao Qian. After arriving at the new place, Lao Qian received instructions from his superiors to steal financial documents about 731.

While working, Lao Qian endured the pain and went to a Belarusian doctor for surgery.Guan Xue recalled seeing Zhuo Wu and began to think about the twins.Pan Yue met Mr. Ning, the military commander, and Mr. Ning promised that if Pan Yue found the list of the Harbin underground party, he would make Pan Yue the chief of the Shenyang Police Department.

On the train, the important staff of the Japanese military aircraft were heavily protected. Song Zhuowu and his comrades disguised themselves and cooperated, and finally obtained the meeting minutes and took photos.At night, at Lao Qian's residence, the film secretly taken from the train was developed, and the meeting records were shocking.

During the meeting, the Kwantung Army Chief of Staff asked all departments to step up preparations for the Tonghua Defense Plan to deal with a sudden Soviet attack. At the same time, he said that it would be okay even if the Kwantung Army did not have reinforcements from the Pacific, because the secret weapon developed was a ceramic bomb.It can be put into use in a few days.“Tonghua Defense Plan” and “Ceramic Bomb”, these are two unheard of but significant pieces of information.

This may be the last desperate struggle of the Japanese army.The Harbin underground party must find out the truth about “Tonghua Defense Plan” and “Ceramic Bomb”.Lao Qian attracted the attention of the Japanese by deliberately releasing the news of “ceramic bomb” in the underground intelligence trading market.

Pan Yue inspected the train and realized that the document may have been leaked.Guan Xue began to plan how to deal with Song Zhuowen and Song Zhuowu before going to Japan.

Guan Xue brought Zhuo Wen to the pigeon cage to feed the pigeons and persuaded Zhuo Wen to go to Japan with her, but Zhuo Wen declined.Lao Qian brought Junko's father Nakamura to Director Long's house and asked Director Long to prove that his son died in Unit 731.

In order to avenge his son, Director Long promised Lao Qian and used the alumni association to make an appointment with Dr. Kojima from Unit 731.The security of the Alumni Association is handled by the Secret Service Section.

Pan Yue and Hu Bin discussed that Song Zhuowen would definitely take action at the class reunion, and the two discussed working together to catch Song Zhuowen.Song Zhuowen and Zhuo Wu originally planned to kidnap Dr. Kojima at the class reunion.When Guan Xue saw that Song Zhuowen was not following her, she arranged for a killer to kill Song Zhuowen at the alumni meeting.

On the day of the alumni association, Director Long killed Dr. Kojima himself before Zhuo Wen could take action.After the chaos at the alumni association, Ding Peng died in a bomb explosion.The killer arranged by Guan Xue did not dare to kill Zhuo Wen for fear of getting into trouble.​

Pan Yue and Hu Bin reviewed the scene and almost proved that Song Zhuowen was definitely a twin.They decided to bypass Section Chief Guan and deal with Zhuo Wen directly.

Guan Xue met Song Zhuowen, and Guan Xue pointed out that Song Zhuowen was a Communist, but Zhuowen did not admit it.Guan Xue knew that Pan Yue had defected to the Kuomintang, and also knew that Pan Yue had received two tasks from the Kuomintang, one was to obtain the Tonghua Defense Plan, and the other was to eliminate the party.

Guan Xue asked Zhuo Wen to prevent Pan Yue from getting the Tonghua Defense Plan.Guan Xue found Xiao Kai and said that she could not take Guan Kai to Japan immediately. Guan Kai was very sad and felt abandoned by his sister.

Guan Kai found Mr. Ding and killed him.Zhuo Wen realized the crisis of the situation, put Xie Yue on the train and asked her to leave him.Asano Daigo finally got his wish and retreated to Manchuria with Unit 731.​

Guan Xue decided to take Hu Bin to Japan, but Hu Bin felt that after going to Japan, he would be Guan Xue's dog, so he refused Guan Xue's invitation.Zhuo Wu went to the Manchuria Railway Building to steal the Tonghua Defense Plan, but was discovered by Pan Yue.

Pan Yue chased after him and was about to catch up with Zhuo Wu.Unexpectedly, because the distance was too close, the killer who wanted to kill Zhuo Wen was hit with a sniper rifle, killing Zhuo Wu.​

Guan Xue drove Zhuo Wu away, but she still mistakenly thought it was Zhuo Wen and invited Zhuo Wen to go to Japan with her.She didn't realize it until Song Zhuowen forced her car to stop with a gun.

In the early 1950s, Zhuo Wen was already a cadre in Fushun City, New China. Today he was not busy at work. He cooked a few dishes and came to the war criminals' station to visit Guan Xue.On the way, they also met Hu Bin, who was being taken to the execution ground and shot.

This was the first time the two met after the war, and the two talked about the endings of the others.Xie Yue participated in the War to Resist US Aggression and Aid Korea, and got married to her comrades on the battlefield.Guan Kai hanged himself because he mistakenly believed that his sister had abandoned him.

After Song Zhuowu's victory, he was killed by Guan Xue's subordinate Xiao Wu.Song Zhuowen left the war criminals' camp and walked alone on the street, recalling the past and couldn't help crying.
