After a while, Han Sicheng asked the forensic doctor and forensic personnel to immediately conduct an autopsy and investigation of the scene, while Shen Mingyu was pondering the content of the text message and the words written on the table, Han Sicheng asked: "Do you have a clue, this seems to be a kind of notice or something." "Not yet, I'm wondering if it will be related to Cui Hao's case, but Cui Hao's case didn't find scorpions and words, I still don't understand, I don't know if there are any clues left at this scene, and there is an anonymous text message, whether he is the murderer or an insider."

After a while, the forensic doctor came to report the situation: the deceased Qi Yan, 30 years old, an employee of the factory, the cause of death ...... As you can see, the body is still warm by the ice crusher, and the estimated time of death is about an hour. "Let's investigate the basic situation of the deceased first." Han Sicheng said. After a while, he walked over with the information he had collected, "Qi Yan, a native of City A, 30 years old, is a factory employee, once molested a female junior high school student, was sentenced to 4 years for forcible indecency and insult, and came to work in this factory after being released from prison. "It's obscenity again...... This is the same as Cui Hao, so we can also start from this aspect, let's go to his rental house and have a look. Han Sicheng agreed. When I came to Qi Yan's rental house, a musty smell and the smell of wine came to my nose, the dirty and messy room was full of empty wine bottles, and there was a computer without a password on the table. The kitchen has dishes and chopsticks that haven't been washed for a few days, and the pot has formed a thick layer of grease and is crawling with flies. There were no valuable clues in the room, and a certificate of release was placed in a dusty drawer. "It seems that this is the end of his life and entertainment." Shen Mingyu complained. Han Sicheng found the landlord, and the landlord told them: "I have a relatively remote place here, the rent is relatively cheap, only 700 yuan for one bedroom and one living room, this guy came to rent half a year ago, he was carrying a bag, trembling, I saw that he was looking at the rental information on the wall, I asked him if he wanted to rent a house, he said yes, I took him to see this room, and then he felt that the price was okay, I said to pay one and pay three, but he didn't seem to have so much money, he could only afford two months, He told me that when he found a job, he would pay on time, and I saw that he was working very hard alone, so I agreed to him, I have a lot of houses for rent, and I usually only come here when I collect rent, and he also pays on time. "Half a year ago, when he was just released from prison, he went to the factory not long after, and we went to ask the leaders and people in charge of the factory." Han Sicheng said.

They returned to the factory, and the leadership of the factory had already come. Zheng Quanping, the general manager of the factory, is usually responsible for handling most of the things in the factory. "Hello Manager Zheng, I want to ask you about Qi Yan, an employee." "Officer Han, this employee's problem is not very clear, you can ask Xiao Pan of the personnel department, she is responsible for managing the human resources system of our factory." Zheng Quanping said. Pan Qiong, a staff member of the human resources department of the factory, is responsible for the management of human resources. "Hello Miss Pan, I want to ask about Qi Yan, an employee of your factory." "Okay, I'll take a look at the information, he came here a few months ago, because we happened to be short of night shifts here, and the work intensity was also high, and there were not many people who came to apply, and he came to apply that day, and I told him that this work was very intense, and he needed to work night shifts for a long time, can you accept it." He accepted it without hesitation, he said that as long as he had a job, he would be fine, and then when I registered his information, I found out that he was a prisoner who had been released from prison, so I asked him about it, and he said that he had been in prison for several years before. I wasn't sure if I could recruit him, so I asked the manager, who said they should be given a chance, and the night shift happened to be vacant, so I hired him. You can ask his squad leader for the specific work situation. "Damn, kick the ball, let's go find the squad leader." Mo Wei is Qi Yan's squad leader, and is usually responsible for supervising and guiding their work. "Hello Mo Gong, I want to ask Qi Yan about his work." "This young man is a person who has been released from prison, I know, he usually works okay, but he is always late, I have told him many times about this problem, but he is always like this, we happen to be short of night shifts here, so I can only turn a blind eye." "Have you ever heard of who he has a good relationship with or who hates him?" "I don't know, I heard that he has no family, he is silent in the factory, he doesn't have any friends, and his usual hobby is drinking." "Okay, thank you for your cooperation." Han Sicheng turned his head and asked the manager again, "Is there a surveillance camera in the factory?" The manager replied embarrassedly: "Originally, there was, but then it broke down because of a power outage, and nothing usually happened, so I was too lazy to get it, I didn't expect such a thing to happen......" "Is this blower and ice crusher usually placed here?" "No, I only moved here in the past few days, because the equipment needs to be maintained from time to time, and we usually move the equipment that needs maintenance to this warehouse." The manager replied. Shen Mingyu frowned, and said to Han Sicheng: "It seems that the murderer has seen the situation in advance and stepped on it before he is ready to come up with this technique." "Yes, let's go and ask if outsiders can come and go here." When they arrived at the gate, they realized that there was not even a security room. "This security ...... It's like going back to your own home. Shen Mingyu complained. Manager Zheng, don't you have any security guards here? It seems that outsiders can come in casually. "Well, there was originally one, but I quit last month because I don't usually have many people here, and we usually ask the employees on the night shift to pay more attention." Manager Zheng replied awkwardly. "This case is also very tricky, Cui Hao's has not been solved yet, and now there is another one, and I have no clue." Han Sicheng said to Shen Mingyu. "I feel inseparable from the text messages I received, he can send us a message in advance every time, he is still a little afraid that we can't find it or not in time, I try to reply or contact him every time, but you know, there is no response at all, I feel that he should want to challenge us, not only hope that we will find the crime scene quickly, but also give us tips from time to time, it feels like a ...... is leading us down his path. "I also asked the technical department to help check this anonymous number, but the place of belonging is abroad, it seems that his anti-reconnaissance meaning is also very powerful, I feel that he is watching us by our side." "Do you suspect that there is an inner ghost?" "What are you talking about, I mean he probably enjoyed the process, maybe every time he committed a crime, he was around and watched." "It's very possible, but I don't have a clue now, this is much more tricky than the last case at the University of Finance, I can't even analyze what kind of person the murderer is now, the only thing I think of is this murderer, he is as fast as the wind, his movements are very clean and neat, and he always provides us with information at the first time." "It's as fast as the wind, this is the content of the military battle chapter in "The Art of War", does he often watch the Art of War?" Han Sicheng said. As soon as he finished speaking, Shen Mingyu's mobile phone received a familiar text message: There are many soldiers, but there is no martial arts, which is enough to combine forces, anticipate the enemy, and take people. But those who are careless and vulnerable, they will be captured. "This is the content of the marching chapter...... What does he want to express?" Han Sicheng said. "Marching Chapter...... Does he want to start the next crime, there are not more soldiers, but there is no military advance, is this a mockery of us, the more troops dispatched, the better, as long as you don't rashly attack and despise the enemy, you can win. He seemed to be mocking us for spending so much manpower and not making progress, saying that we have no way, and if we think carefully like him, one person can win. Shen Mingyu analyzed. This is a mockery of the face...... But we really don't have anything to do now, so let's go back and wait for the forensic personnel's investigation report. Han Sicheng said helplessly.

Back in the team, Han Sicheng asked everyone to rest first. Shen Mingyu returned to the dormitory, although he was very tired, but he couldn't sleep, he had been thinking about the case, he decided to ask Zhong Qiming what he thought again, he called Zhong Qiming's phone: "Qiming, have you slept, there was another case recently, and the murderer also left the content of Sun Tzu's Art of War, and we don't have a clue here, so I want to ask you what unique insights you have." "I'm just about to go to bed, since you called, then I'll also help you analyze and analyze, the murderer should be a person who is familiar with and understands Sun Tzu's Art of War, plus he also sent a text message to remind you, indicating that he should be a very confident person, thinking that his methods are almost seamless, he should enjoy this process of playing with you, I don't think you have to start from the people around you, it may be imitating crimes or serial killings, and the rest, because I haven't actually come into contact with it, so I don't have any thoughts for the time being, You are facing a formidable enemy. Zhong Qiming expressed his thoughts. Thank you, brother, next time I would like to invite you to drink. "You say that every time, and then you don't come once, right?" "I've been too busy lately, one case after another, and I'll be sure when it's done." After making the call, Shen Mingyu went to the bookshelf and picked up a copy of "The Art of War", which he had bought with Thirty-six Strategies before, but because he was too busy, he rarely had time to flip through it. He looked at it, as if he had realized something. He dialed Han Sicheng's phone: "Hey, I found out the law of the crime, the murderer should have committed the crime according to the "Art of War", Cui Hao was buried in the mountain after being killed, which corresponds to the sentence that it is not moving like a mountain, and Qi Yan was blown into the ice crusher by a blower and strangled in front of him, which corresponds to his speed like the wind, the wind forest volcano and thunder, as for why he started from the mountain, it is estimated that he was just killing Cui Hao three years ago, and he didn't think of this, and now he just thought of this, so he killed Qi Yan as if he was killed by the wind, Otherwise, the method of killing Qi Yan a drunkard is very simple, and there is no need to prepare so much, it seems that this murderer has a sense of ritual, he appreciates his work very much, if I am not mistaken, the next one should be his Xu Rulin, but there are so many forests in City A, I don't know where it will be. "That's true, but the forest is too big in the whole city to search them one by one, and it may surprise the snakes." "Are we going to sit still...... He is such a confident person, he shouldn't be in a small place now, and there is a big forest in City A...... Forest Park, as well as Tianguan Mountain, why don't we try our luck? I feel like he's not far from committing the next crime. "We'll send two teams of men to squat and take a look, and we'll set off tomorrow morning." Han Sicheng replied.

Early the next morning, the officers set off, one team went to Tianguan Mountain, and the other team went to Forest Park. Han Sicheng and Shen Mingyu went to Tianguan Mountain, Tianguan Mountain is not big, but the forest is very dense, and the two of them don't know which point to guard for a while. So they had at least one police officer at every corner, and they waited in the densest part of the forest. Han Sicheng also assigned tasks to his colleagues who went to the forest park on the other side, and everything was ready, just waiting to see if the murderer would really do what Sun Tzu said in the Art of War. Two hours passed, and no news came from all over the country, and everyone was still waiting in place. At this time, Shen Mingyu's mobile phone remembered the text message prompt again. Shen Mingyu hurriedly took out his mobile phone, only to see that it was written: It seems that you will also act in advance, but I'm sorry, my speed is relatively fast. Near the Forest Park Ecological Park, let your colleagues look for it, there should be what you want, by the way, your defense is negligent, I am very familiar with the road here, so I easily bypassed your colleagues. Seeing this text message, Shen Mingyu was so angry that Han Sicheng didn't look good on his face, but after all, he was still experienced, and immediately asked all the police officers guarding Tianguan Mountain to go to the forest park to support.

The two rushed to the forest park with their colleagues, and the police officers stationed in the forest park had already arrived at the scene in advance, they came to the ecological park, and after passing through a dense forest, they came to the end, the police officers had blocked the scene, and the forensic doctor was already conducting an autopsy. When the two saw the scene in front of them, they saw that one person's head was smashed, his flesh and blood were blurred, and he was hanging from the largest tree, and a note was pasted on the trunk of the tree, which read: Qi Xu Rulin. The corpse of a poison-tailed scorpion was also placed next to the tree. The police put the body on the ground, and the forensic doctor gave an analysis report: the deceased Yin Bo, 26 years old, died due to intracranial hemorrhage caused by a violent blow to the head, in addition, there were strangulation marks on the neck, which should be postmortem injuries. The time of death was about 3-5 hours ago.

Shen Mingyu said: "It is estimated that another person has been in prison, I feel that I still have to start with Cui Hao and investigate the situation of the deceased first." Han Sicheng contacted his colleagues to investigate the deceased Yin Bo, and after a while, Han Sicheng said: "Yin Bo, 26 years old, from City A, his family is quite rich, his father is a middle-level leader of a telecommunications company, his mother is a university professor, he should be regarded as a rich second generation, he has been pampered since he was a child, his private life is chaotic, he was arrested for raping a girl at the age of 13, but because he was a minor at the time, coupled with the support of his family's relationship, he didn't do much later, and then he spent money to go to a junior college and harass students in the school as a whole, But because it is a related household, this matter has passed, and after graduation, I am idle all day in the bar, and I have no job at present. "Looks like we're going to have to talk to his parents about their precious son." Shen Mingyu said.

The two went to Yin Bo's house and met Yin Bo's parents, who looked very sad at the moment because the police had informed them of the situation. "Uncle and aunt, I know that you are grieving now, but we want to ask you some questions, which will also help solve the case and give you justice." Han Sicheng said politely. Both expressed understanding. Yin Zhenhua, Yin Bo's father, a middle-level leader of a telecommunications company, treats people modestly, and colleagues and friends have a very good impression of him. Yin Zhenhua said: "My son disappeared yesterday, because he loved to go out to play, we said many times but can't care, often the next day or the third day to go home, but one thing we are sure of, is to call his call he will definitely answer, yesterday we saw that he was a little late at night and did not come home, thought he was playing outside again, I made a call, but he didn't answer, I thought he might have drunk too much, I didn't particularly care, after getting up in the morning, I saw that he hadn't come back, so I made another call." ,Still no one answered.,And then I felt that something was wrong.,It stands to reason that I should have woken up in the morning.,Then I said I'm waiting for a while.,If there's no news, I'll call the police.,As a result, I received your call.。 Yin Zhenhua sobbed as he spoke. Meng Yu, Yin Bo's mother, a professor at a university in City A, usually has a rigorous style and high teaching quality, and is well received by students. Meng Yu added: "Abo likes to make friends with those drinking friends, they are all fooling around, we have persuaded many times but to no avail, I know the name of the bar they go to when they get old, MAX Bar, I heard Abo say that as long as you go there to report his name, there will be an exclusive seat, police officers, you can also go there and ask, you must help us catch the murderer!" There were no useful clues at Yin Bo's house, so the two had to go to the MAX bar, intending to ask Yin Bo's fox friends as Meng Yu said.
