Lan Anran wanted to know if Chen Yu believed what Wu Zhenfeng said, and felt that the relationship between Chen Yu and Wu Zhenfeng must be very unusual, because Chen Yu also had a jade pendant on Wu Zhenfeng.However, Chen Yu felt that what Wu Zhenfeng said could not be confirmed yet, so he went to a bar in Wong Tai Sin to conduct investigations before revealing the truth. However, he could not report the matter to his boss because the last time he arrested Bo Laobao, someone leaked the secret.If they fail, the two of them are not enough. If they call Yang Yi together, they should have a better chance of winning. After all, Yang Ye is still trustworthy now.At this moment Yang Yi passed by, so Chen Yu told him the matter. This surprised Yang Yi and wanted to tell Lin Dezan and the others. When Chen Yu saw that Yang Yi was going to do something bad, he stopped him.

After the three people went to the bar, Yang Yi always felt that they should report to their superiors, but Chen Yu insisted that the three of them complete the task, otherwise they would be ruined if the secret was leaked, but they must also strive for opportunities for meritorious service.Yang Yi and the others put monitors on Lan Anran and entered the bar to keep track of her situation.

Wong Tai Sin was negotiating with a Hong Kong drug dealer in the bar. He wanted to give him all the rhubarb capsules in his hand. He also said that his current situation was very dangerous. After all, he was making drugs on Dong Ge's territory and he would definitely not spare him if he found out.Their price was very low, so the Hong Kong drug dealer asked Wong Tai Sin to arrange the trading location for the next day before making a decision.

Just after the Hong Kong drug dealers left, Lan Anran went in and told Wong Tai Sin that he had been selling goods at Lao Ba's place to eat for himself, but Wong Tai Sin knew that Lao Ba didn't know that his bar was also a gathering place. This made Chen Yu and Yang Yi outside very upset.Worried, he quickly rushed in to rescue him.At this moment, Wong Tai Sin discovered that there were police officers and asked people to light all the rhubarb capsules. After they lit them with detonators, Chen Yu went in, took the detonators with his bare hands and ran out and threw them directly out the window. Captain Liu also led people to rushArrived, Wong Tai Sin and his party were all captured and brought to justice.

After returning, Team Liu scolded Chen Yu severely, blaming him for being unorganized and undisciplined. Lin Dezan also felt that Chen Yu and the others should report back in advance. Fortunately, Yang Yi told them so they didn't, otherwise it would be too late to regret.However, Yang Yi felt that Chen Yu was not rewarded for his eagerness to perform meritorious service when he returned home. This made Chen Yu very angry, but Lan Anran also intervened. It was because he failed to arrest Lao Ba last time that he was not rewarded. This made Lin Dezan feel uncomfortable., asked Lan Anran to directly name the suspect, but they still held back. After all, there was no conclusive evidence that it was Lin Dezan.Later, Lin Dezan asked them to write an examination and submit it, but Chen Yu felt that Wu Zhenfeng should be interrogated because he felt that Wu Zhenfeng still had many things that he had not said.

Team Liu interrogated Wong Tai Sin and wanted to know where he was on the night of the 9th when Hu Qingshan was killed, but Wong Tai Sin claimed that he was singing incense sticks.

Chen Yu interrogated Wu Zhenfeng and told him that Huang Taixian did not admit that he was at the Weixiang Restaurant, so all the evidence proved that Wu Zhenfeng killed Hu Qingshan. If he did not tell the truth, no one would be able to help him.Wu Zhenfeng told Chen Yu that he was drugged by Wong Tai Sin and the others, and he didn't know anything after he fainted, but he convinced Chen Yu that he definitely did not kill anyone.

Lan Anran went to learn about what happened when Wong Tai Sin was a custodian in the pharmaceutical factory. When Wong Tai Sin was working as a custodian, the warehouse was often stolen, and their deputy director Li Zhengqiang often tried to cover up Wong Tai Sin's mistakes, so after returningHe gave the information to Chen Yu, and the result was completely consistent with the Li Zhengqiang accounted for by Wu Zhenfeng. This proved that Huang Taixian and Li Zhengqiang often used their identities in the factory to steal raw materials for making rhubarb capsules, so Huang Taixian was interrogated, and Huang Taixian was interrogated in front of the evidence.Daxian had no choice but to admit that Li Zhengqiang killed Hu Qingshan.

It was Li Zhengqiang who called Wong Tai Sin before and learned that a man named Brother Feng wanted to tell Brother Dong about their production of rhubarb capsules. So Li Zhengqiang wanted to kill Wu Zhenfeng and asked him to ask Brother Feng out. As a result, he gave him in the drink.Wu Zhenfeng drugged him, which made Wu Zhenfeng very angry. As a result, Huang Taixian took Wu Zhenfeng away and then copied his fingerprints to frame him for killing Hu Qingshan.The reason why he wanted to kill him was because Wu Zhenfeng wanted to take goods from Dong Ge's territory, but Dong Ge didn't agree, so he wanted to use them as a surrender certificate for Dong Ge.

Hao Dong, nicknamed Dong Ge, led people to find Li Zhengqiang, and beat Li Zhengqiang severely after he had led people to blow up an arm of Lao Zhang before.

Huang Taixian told Team Liu that Li Zhengqiang's hiding place was in the abandoned warehouse of the pharmaceutical factory, so Chen Yu led people fully armed to rescue people.
