Qin Chuan recognized the suspect from the surveillance video and saw him entering the Internet cafe. He immediately led his team to the Internet cafe to investigate.On the way, he noticed that Hu Zhongxing's reward notices were posted in the streets and alleys. Worried that this would alert others, he ordered the criminal police captain to tear down all nearby notices.Sure enough, after Zhang Kehan ​​saw the notice on the street, he was frightened and hurriedly hailed a motorcycle to escape.

After Qin Chuan arrived at the Internet cafe, he immediately asked to see the list of people who came to the Internet cafe on the 27th and checked them one by one.Deng Guangrong was responsible for calling the people on the list to confirm. Among them, only Zhang Feng denied that he had been to the Internet cafe.Qin Chuan immediately sent people to arrest Zhang Feng and carefully checked the computer he used.After interrogation, Zhang Feng confessed that he had taken a passenger to Hexi. Because he had no change to give him, the passenger took his ID card.Zhang Feng also recalled that the man's accent sounded like that of Yuncheng.

Based on Zhang Feng's ID card information, Shi Yan, Deng Guangrong and others investigated the computers that had used the ID card one by one.They found that the man not only browsed the progress of the Yuncheng and Xicheng cases, but also watched several crime-themed films.Qin Chuan thus determined that the person using Zhang Feng's ID card was the murderer.He asked Deng Guangrong to continue investigating on the computer, and finally found the suspect's photo.The Internet cafe owner also recalled that the man was very clean and liked to eat fruits.

The identity of the murderer finally came to light. Deng Guangrong, Shi Yan and others were excited, and Qin Chuan also breathed a sigh of relief.However, due to overexertion, he suddenly suffered from unbearable abdominal pain, but he still managed to sort out the suspect's criminal psychology and motive for committing the crime.Qin Chuan was sweating profusely in pain, and Shi Yan rushed to support him in time.Based on clues, Qin Chuan concluded that Zhang Kehan ​​might have hidden in the cemetery on the mountain.

After Qin Chuan returned to the provincial capital, Zhao Fei accompanied him to the hospital for a physical examination, and it was found that he had a hemangioma in his liver.The doctor advised him to operate immediately, but Qin Chuan insisted on catching the murderer first.However, once a hemangioma ruptures, it can be life-threatening.He Qinglian and Qin Haizheng rushed after learning the news, and He Qinglian forced Qin Chuan to have surgery immediately.Qin Chuan had no choice but to ask Zhao Fei to go to Xicheng to arrest the criminals, and called Tao Wenming to ask for leave.Tao Wenming asked him to treat his illness with peace of mind and stop worrying about Xicheng's case.

Qin Haizheng has been by Qin Chuan's side and feels very sad to see him so emaciated by the illness.Qin Chuan told him to take good care of He Qinglian and Ye Haiping.He Qinglian bought a lot of daily necessities and supplements for Qin Chuan.On the other side, Zhang Kehan ​​secretly called his wife to remind her to take good care of her father and urged her to transfer money to her family as soon as possible.Zhang Kehan ​​also visited the bank and found that there were two security guards and police officers patrolling the streets regularly.

After Qin Chuan came out of the operating room, he immediately called his colleagues to learn about the progress of the case, regardless of He Qinglian's objections.Li Wen took Ye Haiping to visit Qin Chuan. Ye Haiping hugged Qin Chuan and cried non-stop, complaining that he didn't take good care of his body.Qin Chuan was worried about the case, but Ye Haiping was powerless and could only vent his anger on Li Wen, complaining that he had changed Ye Haiping's wishes without permission.He Qinglian hurriedly took Li Wen to buy food, and Ye Haiping was willing to shut up.

The weather forecast said there would be heavy rain in Xicheng tomorrow. Qin Chuan was very worried and called Shi Yan to remind Shi Yan to be careful of the suspect committing another crime.He thought about returning to Xicheng after being discharged from the hospital in two days.Sure enough, on June 28, it rained heavily in Xicheng, causing widespread traffic paralysis in the city.Zhang Kehan ​​was squatting at a construction site in Tianxi District. When he saw the boss of a construction company driving to the construction site, he drew his gun and shot the boss three times.The workers came after hearing the news, but Zhang Kehan ​​was frightened and ran away.

Shi Yan brought the police to the construction site and called Qin Chuan to report.Qin Chuan was anxious, but Zhang Kehan ​​had already fled away.He rode a car and continued on his way, and finally came to the railway track. He was accidentally pricked by an iron nail on the sole of his foot, and he cried out in pain.

He Qinglian and Qin Haizheng came to the hospital and found that Qin Chuan had been discharged and left, feeling anxious and angry.He Qinglian called Zhao Fei to complain, and Zhao Fei guessed that Qin Chuan went to Xicheng.He called Shi Yan and Shi Yan came to the office and saw Qin Chuan had arrived.When Qin Chuan came back from the airport, he was very anxious when he saw police officers with guns and live ammunition along the way.He believed that the suspect did not know how to fly, let alone take a train with such arrogance.Shi Yan advised Qin Chuan not to worry. Xicheng had dispatched all police forces to search, but in the end nothing was found.
