Liu Yusheng is not a good-tempered person, and he doesn't seem to be a good person who is eager for justice and righteousness, which Yuan Yaxian is convinced of. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

If you want to use the lives of innocent victims to impress Liu Yusheng, it is not realistic, it can be seen from Liu Yusheng's lectures that he has a certain opinion and understanding of serial murder cases, but he did not disclose any information to the police. This man doesn't care about the life and death of others, he looks down on all living beings, and it is his nature to be indifferent and ruthless.

Therefore, Yuan Yaxian did not intend to use the next possible victim as the starting point, you can't ask everyone to have a kind heart, moral kidnapping is useless for people like Liu Yusheng, and it is likely to backfire.

Before thinking about how to persuade Liu Yusheng, Yuan Yaxian kept her agreement with Liu Yanyu,

She really didn't say a word, just walked around the office a few times, and then came to Liu Yusheng's desk and observed Liu Yusheng's movements.

Liu Yusheng and Liu Yanyu were preparing the teaching materials for the lecture, and Yuan Yaxian was a policeman after all, so she could easily understand it. It seems that Liu Yusheng wants to talk about the method of destroying the evidence by breaking the corpse, which is really a very strange subject. It seems that what Liu Yusheng is studying is not ordinary criminology, but teaching everyone how to fight the police.

Yuan Yaxian felt that this was her professional sensitivity, maybe it wasn't the case, but she always felt a little uncomfortable. Next, she saw a case carefully prepared by Liu Yusheng, who circled and marked many places in a book, and asked Liu Yanyu to arrange the order of the photos.

This is a classic case of mutilation, in which the destruction of evidence is used to slow down and confuse the police investigation, a common tactic used by deranged criminals. The case chosen by Liu Yusheng is very cruel, specifically about a man's girlfriend who has been in love for many years cheating, and then broke up, and then the woman disappeared.

At that time, the police suspected that the man had killed his girlfriend, but the woman's body could not be found anyway, and if the body could not be found, it could not be investigated as a murder case, and could only be treated as an ordinary case of missing persons. Later, a criminal policeman traced all the way to the end according to a clue, and finally solved the case, and the process of solving the case was also tortuous and bizarre, but that was not the point, Liu Yusheng wanted to talk about how the murderer disposed of the body.

There is no doubt that the murderer is the man who was betrayed by his girlfriend and killed his girlfriend out of love and hatred. The man understands the law, and after he killed his girlfriend, he did not adopt the usual methods of throwing the body, such as tying up stones and sinking into the river, or burying them in barren mountains and mountains overnight. The man used the method of mutilating the body, but instead of dismembering his girlfriend's body and throwing it separately, he chopped her into many small pieces and put them in the refrigerator.

In the days that followed, the man took out a piece of his girlfriend's corpse every day, cooked it and ate it. In the end, when the case was solved, the body of the deceased was reduced to one foot, and the rest was eaten by the man.

Yuan Yaxian saw Liu Yusheng making annotations, and she found that Liu Yusheng used this case as a teaching material, and the focus was all on the means of destroying the body, but she didn't talk about the cold-blooded part of the murderer's destruction of humanity in the case.

Liu Yusheng analyzed in detail the success rate of the murderer's destruction of corpses,

If the murderer can eat the female corpse completely, then the probability of solving this case will be infinitely close to zero. It's a pity that the murderer was too careless, he handled the body well, but he left a flaw in the handling of his own bloody clothes, and it was such a flaw that was caught by the criminal police, causing him to fall short.

According to Liu Yusheng's lecture habits, Liu Yanyu arranged the photos related to the famous corpse shredding case at that time, and she was working hard when she suddenly heard Yuan Yaxian say a word.

"Professor Liu, you are misleading the students by doing this, if there is a murderer among your students, it will be a disaster! For under your teaching, he will not be condemned. Yuan Yaxian said heavily.

Liu Yusheng had long known that Yuan Yaxian was present, but he ignored this woman, and at this time, Yuan Yaxian's words that were close to duty did not move him, he just said calmly: "No matter how cunning the fox is, he can't fight a good hunter, I believe in the ability of the police." ”

When Liu Yusheng said this, he didn't have a strange tone, and he couldn't tell if he was mocking or what, Yuan Yaxian felt a little fever on her face, because of the existence of serial murders, she felt that Liu Yusheng was deliberately humiliating the police.

"Professor Liu......"

"Yaxian!" Liu Yanyu interrupted Yuan Yaxian's words, "Aren't you going to eat?" I've packed up, let's go! ”

Liu Yanyu didn't care whether Yuan Yaxian agreed or not, she was about to leave. Of course Yuan Yaxian didn't want to go, she had a lot of strength, Liu Yanyu couldn't pull her, the two froze there, Liu Yanyu whispered helplessly: "What are you doing?" Didn't you say you wouldn't be allowed to speak? ”

"I'm sorry, Xiaoyu, I do have something, but I'm not looking for you, I'm just here to find Professor Liu." Yuan Yaxian said apologetically.

Liu Yanyu sighed and said: "I have already seen it, you are so busy, and you are catching up with a serial murder case recently, and the pressure from the police is so great, how can you have time to come to me to play." But I'm an apprentice brought by Professor Liu, and if I want to help you, I have to pay attention to proportion, so I can only pretend not to know at this time and drag you away......"

When Liu Yanyu said this, his voice was very loud, and he didn't mean to hide it from Liu Yusheng at all. Yuan Yaxian looked at Liu Yanyu in amazement, she didn't understand what she was doing, if you want to help, just say help, or if you don't help, you won't help, since you are afraid of provoking Liu Yusheng, then pretend not to know, what the hell is it to shout so loudly?

Liu Yanyu turned his head, looked at Liu Yusheng pitifully and said, "Teacher, it's me who is not good, I am reckless, is it okay to take an example?" ”

Liu Yusheng raised his head and glanced at Liu Yanyu, and said with a smile: "You little slippery head, do you want to help your classmates?" If you want to help, just say it, otherwise people won't appreciate it at all. ”

Yuan Yaxian finally realized at this time that Liu Yanyu had been helping herself, and maybe even as soon as she appeared here, Liu Yanyu had already expected her purpose. Liu Yanyu did not expose Yuan Yaxian, but cooperated with her to act, otherwise how could she bring her to Liu Yusheng's office? You must know that not everyone can come in here, and without Liu Yusheng's permission, the principal has to stand outside.

Yuan Yaxian glanced at Liu Yanyu gratefully, turned to Liu Yusheng and said, "Professor Liu, I ......"

"Don't say it yet, let me guess," Liu Yusheng said lightly, "You are a policeman, you came to me to consult about the serial murder case, and you happened to hear my lecture, so you wanted me to go back to the police station for help, right?" (To be continued.) )
