Zhou Xun followed Guan Hongfeng onto the No. 108 bus. Ye Fangzhou drove and followed the bus, calling the person on the other end of the phone to report along the way.Guan Hongfeng grabbed Zhou Xun's gun and restrained Zhou Xun. He explained to Zhou Xun in a low voice that the person who killed Liu Yan did not go to claim the reward. This probably means that the group of people who killed Liu Yan may be the same as those who killed Wu Zheng's family.It is related to the family of five.

An Teng, whose real name is An Ting, is a group with Ye Fangzhou, the detective who was fired from the police station before. Wang Zhige joined them midway and is not a regular member. He suggested that Zhou Xun follow up on this clue.After saying these words, Guan Hongfeng took the opportunity to get out of the car midway, dismantled Zhou Xun's gun on the roadside and threw it away.Ye Fangzhou captured Guan Hongfeng's traces because he followed the bus all the way. When he got off the bus with a knife and prepared to follow Guan Hongfeng, he was arrested by Liu Changyong.

Zhou Xun drove Liu Changyong's car and continued to follow. When he was in the food court, he discovered Guan Hongfeng's traces.At that time, Guan Hongfeng was being followed by several people from another group who came from nowhere. One of the group of people was about to catch up with Guan Hongfeng when he was suddenly knocked unconscious by someone behind him.His gun was then kicked aside.Han Bin guided Guan Hongfeng to help him escape Zhou Xun's pursuit. Guan Hongfeng asked him why he helped. Han Bin bluntly said that it was the brothers' persistence that moved him.

The place where Hu Qiang broke into and robbed was No. 201 of Donghuayuan Community. Guan Hongyu and Zhou Shutong entered the community. A man in his 40s named Dong Qian lived there. He himself taught at Jiangzhou Vocational and Technical College.According to his explanation, September 15th two years ago was the college sports meeting, and he had been serving as a track and field referee. After the track and field event, he went to the antique market on Faxi Road, but returned home before seven o'clock, and heThere was no break-in or robbery that day.When Guan Hongyu was answering, he observed that there was a display cabinet full of Lafite red wine in the room. The vintages ranged from 1961 to 2005. These were all collection-level red wines.He realized that this case was unusual, so he sent a text message to Fatty, saying that the case was suspicious and would be delayed for a while.

However, according to Hu Qiang's confession, he was the victim hit with a wine bottle two years ago, and Dong Qian's display cabinet happened to be missing a bottle of 90-year-old red wine.Zhou Shutong guessed that the bottle of 90-year-old wine was used by Hu Qiang to hit people.In addition, Dong Qian is very clear about what he did on September 15th two years ago, which shows that Dong Qian is indeed suspicious, so something must have happened on 201 two years ago.

Guan Hongyu and Zhou Shutong encountered difficulties when they went to Hongyang Branch to investigate Dong Qian's files. The police were unwilling to agree to investigate for them, so Zhou Xun could only decide to send them a letter of introduction.

Liu Changyong cross-examined Ye Fangzhou. Ye Fangzhou always avoided important clues because of his experience in criminal investigation.He only admitted that he had a business relationship with An Teng and knew nothing else. He also bluntly stated that he was following Zhou Xun to help.Liu Changyong couldn't stand him at first, but he didn't expect Ye Fangzhou to say bad words this time, calling Liu Changyong an ignorant and violent person. No wonder Zhou Shutong didn't like his father.Liu Changyong was so angry that he left the interrogation room. Zhao Qian, who accompanied the interrogation, had to leave Ye Fangzhou's contact information and let him go.

When Ye Fangzhou left the police station, he met Zhou Xun. Zhou Xunzun advised him that he would not die if he did not commit suicide.

Zhao Qian investigated and learned that Dong Qian was from Shenyang and had worked in Shenyang Youwang Chemical Factory for nearly ten years.A chemical leak occurred in his factory a year before he resigned, killing two workers. After that, he resigned, divorced, and moved to Jiangzhou six years ago.He was the workshop director at that time, and the factory also gave him a compensation.Although houses in Jiangzhou were very cheap six years ago, he still had spare money to collect red wine. Guan Hongyu concluded that the factory must have given him a lot of money.

The next day, Guan Hongyu and Zhou Shutong came to find Dong Qian, but Dong Qian was not at home.Property surveillance showed that Dong Qian left home at 5 o'clock yesterday evening and never came back. When Guan Hongyu and Zhou Shutong entered the room, they found that there were no shortage of clothes and toiletries, but a bottle of 1961 red wine was missing from the display cabinet.Guan Hongyu knew that Dong Qian had run away, so he asked Zhou Xun to send Hu Qiang to Jiangzhou to identify the scene.

The gun Zhou Xun picked up in the food court proved to be a scrapped gun from the police station, and because the guns used by Wang Zhige and An Teng also came from the police station, Liu Changyong concluded that the gun belonged to Guan Hongyu after encountering such situations several times in a row., and Guan Hongyu is definitely from An Teng's group.Zhou Xun had different opinions with him. He felt that if “Guan Hongyu” had a gun, there would be no need to snatch his gun and throw it away, so the gun was dropped by someone else who was chasing “Guan Hongyu”.He analyzed that there were people chasing “Guan Hongyu” behind him, and there must also be people helping him escape.However, because Gao Yanan has been under surveillance, Zhou Xun does not know who will help him, but he is very sure that the person who helps him must be a master.

Guan Hongfeng and Zhou Shutong followed Dong Qian's driving surveillance to the middle of the highway intersection, where there was an abandoned road leading to Nashan Mountain. Guan Hongyu wanted to go to Nashan Mountain to investigate alone, but Zhou Shutong refused to agree, so he had to take Zhou Shutong with him.They found the tire tracks of a car on the Nashan Highway and drove all the way to the fork in the road. They found Dong Qian's car parked on the side of the road.
