In Nanxing City, Jingchu returned after ten years of absence. He found that in the past ten years, some people who appeared here and did not appear here seem to have nothing to do with each other, but they are in a huge network of relationships. Everyone may be a spider or a prey, and at the moment of capture, they become a deadly threat to each other.
When Jing Chu came to the commissary, he saw that the owner Fan Wei had a problem with his legs, so he hurried to find out what was going on. Fan Wei looked very unnatural, and ended the conversation with him on the grounds of selling goods.
Liu Daren, the captain of the Serious Cases Brigade of the Criminal Investigation Division of the Nanxing Public Security Bureau, was furious in his office. Because Jing Chu, who went to work on the first day, was late, Liu Daren felt that he did not take discipline seriously. After Jing Chu came, he didn't explain the reason for his lateness, only that it was his own problem. Investigators Chang Yan and Zhou Zisheng took the initiative to greet Jing Chu. Jing Chu could see at a glance that Zhou Zisheng was wearing new clothes and was about to invite the girl he liked to eat at Dongling Pavilion. Knowing that Yang Mianmian was missing, Liu Daren hurriedly took Jing Chu to find her.
Yang Mianmian is an ordinary senior high school student in Nanxing Middle School, but she has some unusual features. She can remember everyone she has met, everything she has encountered, and she can tell where so many sounds and smells come from. The way she communicates with the world is somewhat special, however, this is only a secret she knows.
Liu Daren couldn't find Yang Mianmian and couldn't make the phone call. He was very anxious. Jing Chu asked him to give Yang Mianmian's phone number to himself, and then, pretending to be a takeaway, called Yang Mianmian. Through the dialogue with her, Jing Chu guessed where she was, and hurried to look for him. At this time, Yang Mianmian was catching the thief. Based on her own judgment, she speculated that the thief might be in the canteen, and hurried over. The two people walking towards each other ran into each other, Jing Chu caught her without any effort, and promised to accompany her to catch the thief.
After Yang Mianmian's description, Jing Chu inferred that the thief may have no fixed home, and it is likely that he is in an Internet cafe. Just in time for the meal, Jing Chu speculated that he was eating at a high-end Sichuan restaurant, and hurriedly took Yang Mianmian to catch him. Seeing Jing Chu catch the thief neatly, Yang Mianmian admired it very much. Jing Chu stated that he was sent by Liu Daren to arrest her, and took her back directly.
Jing Chu believed that Yang Mianmian had misbehavior, had no teacher, and disappeared all day long. If he was not strictly disciplined, he might go astray, and he did not want to waste the time of the entire serious team on her. Hearing this, Song Chengan, the head of the Criminal Investigation Division of the Nanxing Public Security Bureau, decided to leave the care of Yang Mianmian to Jing Chu.
In Jing Chu's rebellious and paranoid youth, his tutor Yang Xing stubbornly approached him and spent sad moments with him. In an accident, Yang Xing passed away. The perpetrators died one after another, and only one person changed his name and last name: Fan Wei, the owner of the canteen. At this time Fan Wei had been killed and passed away.
According to preliminary judgment, Fan Wei's death time was between five and six in the morning. He should have been strangled with a rope-like object on his neck, and then cut dozens of knives with a sharp weapon. The police found on Fan Wei's cell phone that Yang Mianmian had sent Fan Wei "You are dead" and hurried to find Yang Mianmian. Yang Mianmian couldn't produce proof of his absence, which made Liu Daren very depressed.
Fan Wei is related to the case of falling from a building ten years ago. The boy who fell from the building was Yang Mianmian's brother, Yang Xing. Upon learning of this, Yang Mianmian collapsed. Jing Chu found that Fan Wei's telescope was facing the window of Yang Mianmian's house, and he had some guesses in his heart.
