When Lu Xingzhi returned home, he found that the house was in a mess, and Yang Man was sitting on the sofa with red eyes.He hurriedly checked the child's welfare and found that the child was sleeping peacefully, so he sat next to Yang Man and asked about the reason for the chaos in the room.Yang Man went on to say that during the day she wanted to go shopping while her child was sleeping, but when she came back she saw her child crying and tearing up her books.Yang Man said that she had no experience in raising children and wanted Lu Xingzhi to send An Ning away so that both of them would not feel uncomfortable.Lu Xingzhi comforted her and said that he would discuss the child's affairs with her when he was done.

The next day, the criminal police team worked on the case all day.Team Huo was busy moving new equipment when he saw Lu Xingzhi passing by and asked about An Ning's situation.When he learned that An Ning was fine, he asked if he knew how to use a computer. He learned that An Ning knew how to operate a computer, so he invited him into the office to help.However, Captain Huo discovered that Wei Zhengrong was not there, and after asking Lao Zhu, he found out that he had gone to Nandu University to look for Bai Xiaofu.

Wei Zhengrong looked for Bai Xiaofu at Nandu University, where he tested the physical evidence sent by the criminal police team and found that it was not human blood but animal blood.He asked Bai Xiaofu to do another test, but Bai Xiaofu explained that she not only wanted to help the criminal police team, but also complete her own work at Nandu University, so she completed the task as soon as possible.She jokingly suggested dividing the lab among the criminal police teams so their test results could come out faster.Wei Zhengrong left helplessly.

On the way back to the police force, Wei Zhengrong met his colleagues who were investigating Zhang Sicheng.When he learned that it was just a small car accident, he asked his colleagues to take care of it and continued to the police station.At this time, Lao Zhu was exploring new computers. Lu Xingzhi knew a thing or two about computers, so he helped with the research.They projected the map onto a blank wall and used a white cloth as a curtain to make the map clearer.When Wei Zhengrong saw this scene, he couldn't help but praise it. He also went to apologize to Lu Xingzhi and handed him a gift to express his gratitude and apology.Suddenly, Wei Zhengrong received a call from Guo Shengli and learned that another fight occurred on Nanshi Street, so he left the police team and went to the scene.

Guo Shengli concealed something about Du Mei last time. This time he called Wei Zhengrong to tell him, but according to the rules he had set, if he lied, he would chop off one of his fingers.He took out the shovel and wanted to execute it on the spot, but Wei Zhengrong threw the cup to stop him, saying that he was a people's policeman and did not have so many rules.After Guo Shengli calmed down, he said that Du Mei had been dating him from 1993 to 1994. Du Mei's family was from the Northeast and she had no family members.Later, the reason why Du Mei left was mainly because what Guo Shengli did was very dangerous, so he left quietly.Wei Zhengrong didn't quite believe it. He felt that Du Mei must have something hidden, and he couldn't stand hearing it anymore, so he stood up and left.Guo Shengli called out to him, saying that he didn't know who was registered, and he wanted to help investigate those who were not registered, but was rejected by Wei Zhengrong.

When going out, Wei Zhengrong heard Hu Haixia asking about the two hundred yuan and how many times he had to fill up the car with gas, so he gave a few perfunctory answers and then went out with a glass full of water.Wei Zhengrong was worried that if he drove the family car again, his wife would be suspicious again, so he offered to drive Lu Xingzhi's car.

On the way to see Guo Shengli, Lu Xingzhi talked about Guo Shengli's situation. After he came out of prison at the end of February, he had been under government supervision, then worked as a cleaner, and recently went to a maintenance shop.After listening to Wei Zhengrong's analysis of the serial killer's situation, he guessed that the killer might have moved, or was in jail for committing crimes, and had only been released recently. He also talked about a few foreign books. Such murderers may have psychological needs, and they imagine that they canTo recreate the murder process, you may visit an insider to learn about the case, or you may visit the police to ask about the process of the case.

When he met Guo Shengli, Lu Xingzhi told him that it was Liu Meng on November 18th, and Du Mei was also killed after that, so he suspected the same murderer. Brother Dao thought it was impossible.Upon seeing this, Lu Xingzhi persuaded Brother Dao to recall carefully. The real murderer might also be in jail just to get close to him for the case.An Ning dreamed that a man wearing a bird-head mask dragged Du Mei into the alley, while she called her mother, run away.Then he saw himself passing by the alley and found someone following him. When he looked back, he saw that it was the man in the bird-head mask he had seen when he was a child. He quickly left on his bicycle in fear.
