Lao Du said that in recent years, there are more strangers in the community than acquaintances, and many uncles and aunts in the neighborhood committee do not know each other. Lu Xingzhi asked him to narrow down the time slot and start watching the surveillance from 12:10 midnight. But at the beginning, they found that there were workers changing shifts on site, and the noisy environment could not be recognized at all. Lu Xingzhi thought of a way, but he had to discuss it with Yang Man. Unexpectedly, when Yang Man learned that he wanted An Ning to watch the surveillance to identify the murderer, she refused without thinking. Lu Xingzhi tried to reason with her, but his voice was a little louder. When An Ning came home from school, Yang Man decided to tell her in person, but before she could bring An Ning to the room to talk about it, Lu Xingzhi passed out due to too much pressure and fatigue recently.
Wei Zhengrong and his son were helping Hu Haixia move things, when he received a call and learned that Lu Xingzhi had fainted, he quickly told Hu Haixia that there was something urgent in the institute and he had to go back. Neither Hu Haixia nor Zhuang Zhuang knew how to drive, so Wei Zhengrong turned back and said nothing. Seeing this, both Hu Haixia and Zhuang Zhuang let him go to work, drive the car, and let Zhuang Zhuang get a flatbed truck to pull the rest of the things. When Lu Xingzhi woke up, he saw Zhao Zhengming's head dangling in front of him. Zhao Zhengming had been in the hospital since the last time he was shot in the head by gangsters. The nurse recorded Lu Xingzhi's physical condition and asked him to continue sleeping. When he woke up again, night had already fallen, and Wei Zhengrong also came. Lu Xingzhi thought of one thing, and after talking about it with Wei Zhengrong, Wei Zhengrong dispelled the possibility of Lu Xingzhi's speculation with the facts.
Wei Zhengrong asked about the reason for the divorce between Lu Xingzhi and Yang Man. Lu Xingzhi said that a prisoner who was captured by him was released and went home with a knife. He was at home and took the knife from the prisoner. No one was hurt, but An Ning was terrified and hasn't been able to sleep since. I asked a psychiatrist, and the doctor's suggestion was to get out of that environment as soon as possible, so Yang Man proposed to live separately. Later, Yang Man's mother kept bringing up this matter, and she didn't know whether she wanted to persuade her to break up or make peace. Yang Man was so annoyed that she simply divorced herself. Yang Man took An Ning to the police station to watch the surveillance. An Ning was surrounded by Dui Huo, Lao Zhu and Lao Du, and An Ning also seemed to have nothing to worry about. Yang Man left her here and went to the hospital to see Lu Xingzhi.
The nurse came over and asked Lu Xingzhi to continue sleeping. Lu Xingzhi actually had enough sleep, as soon as he closed his eyes, it was all about handling the case back then. In 1997, they set their sights on Guapi, and the three went to see Lao Zhu who had recovered, and asked about Wu Xiaowen's situation at that time. In both cases, Wu Xiaowen had an alibi, and they had to continue the investigation. Lu Xingzhi checked Wu Xiaowen's book-borrowing frequency and found that he had borrowed books nine times in total, which was considered a high frequency. According to the confession provided by Wu Xiaowen at the time, the master and apprentice went to ask Wang Pangzhu and others, and learned that Wu Xiaowen had a stationery store in front of Jiangbei Middle School. Wu Xiaowen's grandfather used to be a well-known painter, and Wu Xiaowen was also good at writing. Lu Xingzhi was not sure if Wu Xiaowen was the one who took the child away that night.
Wu Xiaowen closed the stationery store early, and rode straight to the city library. Lu Xingzhi stared at him, and Wei Zhengrong went back to the bureau to ask Team Huo for help. In 2010, Lu Xingzhi woke up and learned from Yang Man that An Ning seemed to recognize someone last night, so he was immediately discharged from the hospital and returned to the bureau. An Ning's identification allowed Huo Bureau and the others to lock the target and draw out the area where the suspect had never left. After that, everyone was spinning around, and Lao Lu accidentally found that there were blood stains on the brooch and black cloth.
