A woman was jogging alone in the woods, when she suddenly tripped over something and fell, and when she got up, she looked up and saw a corpse, which frightened her into a hurry.

A man was hung from a tree in a very strange position.

Gradually examining the man's many rough wounds, his hands and feet were tied, it was clear that this was a murder.

The hanging pulley has left rust on the tree, indicating that the pulley was not installed temporarily. The police found a rag and the body of a puppy under the tree, which was mutilated and scarred exactly like the dead man. Police identified the man, Xu Fan, a local university professor.

The forensic examination found that Xu Fan had many punctures on his body. Contusion. Cuts. There are different types of pinholes. His eyelids were glued and his retina was burned. The forensic doctor judged that Xu Fan was angry and suffered inhuman torture for 6 hours, and finally died of suffocation, obviously the murderer hated Xu Fan. And Xu Fan also had two small blisters on his body, which were caused by being hit by a stun gun at close range.

The survey found that Xu Fan's reputation at the university was clearly polarized, with students thinking he was a genius and teachers thinking he was a madman. Because Xu Fan often showed videos of massacres and punishments to his classmates. Xu Fan once said: "Hatred is innate, it is instinct, without hatred, people are not human."

This non-mainstream discourse was very popular among the students, and Lao Ji collected DNA samples from all of Xu Fan's students. After testing the DNA on the cloth to be consistent with that of student Applejack, Applejack said, "I hate Professor Xu Fan's way of teaching, he has been torturing students, but he is very excited in the process of being abused", which makes him have to believe that Professor Xu Fan's theory of pain is true.

During the questioning, Lao Ji found that Applejack was very afraid of Xu Fan, he couldn't be the murderer, so could the murderer be one of Xu Fan's classmates? Maybe this person was abused by Xu Fan's class, and finally killed Xu Fan.

Lao Ji stayed with Xiao He to go to Xu Fan's house to investigate, but saw the student Xiao Ling sorting out the information. It turned out that these students had a very good relationship with Xu Fan, and Xu Fan gave them the keys to their homes, so that the students could come over to deliver reports or help deliver some food.

The investigation found that the shredder had recently been activated, and Lao Ji found a suspicious cabinet in the corner, which was actually locked. Xiao He pried it open and saw that it was actually a criminal detention. Good guys, that's everything.

But after the beating test, Sister Xi found that all the wounds caused by the torture instrument did not match Xu Fan's body, but what could match was the puppy corpse found at the scene, and the blood on the torture tool was also that of the puppy.

It seems that Xu Fan used these torture tools on animal cruelty, and sure enough, Xiao He restored the shredded documents from the shredder, which was an experimental note for dog abuse, and in the note, Xu Fan mentioned that he wanted to use the experiment on his student assistants. It seems that the biggest suspect at present is the student assistant, the police want to extract the fingerprints on the keyboard, find out who this student assistant is, but the keyboard has been cleaned, there are no fingerprints at all.

This is a mark that Xiao He found in the copy on the side, which was printed out as half a human face, and there was a jar of unused super glue next to it.

Lao Ji looked at the office utensils on the table, the stapler. Tacks. The nail remover is complete. He came up with a terrible conjecture that it was not fingerprints that had been erased from the fingerprints, but bloodstains. Sure enough, after Sister Xi sprayed the detection reagent, the bloodstains on the stationery appeared, and Xu Fan was killed here.

After investigation, Xiaoling was Xu Fan's student assistant, and the police took out a search warrant and asked Xiaoling to hand over the electric shock baton. Xiao Ling knew that she had been exposed, she handed over a mobile phone, and the police checked and found that it was a tool that could electrocute the dead, which was really smart enough.

In this way, Xiaoling was arrested and brought to justice, and in the face of Lao Ji's interrogation, she still praised the professor for being a genius. Lao Ji asked directly: Is the injury on your hand something that a genius professor should do to his students? As soon as these words came out, they instantly struck Xiao Ling's heart.

Xiaoling said: "What qualifications do you have to challenge the authority of the professor?"

It turned out that with the idea of respecting the teacher, Xiao Ling has always been tolerant of Xu Fan's approach, but Xu Fan has intensified, and he scolds Xiao Ling at every turn. Xiao Ling, who couldn't bear it, shocked Xu Fan and told him to shut up. retaliated against Xu Fan with various torture instruments, stabbed and poked, and beat Xu Fan severely, shouting all the time: "Do you dare to scold me for being mentally retarded?" Do you dare to say that I am a waste"? She still didn't get rid of her hatred, and after gluing Xu Fan's eyelids with super glue, she used the bright light of the photocopier to burn his eyes over and over again.

Xiao Ling took Xu Fan to the woods, ready to perform the final torture, she tied Xu Fan up and hung him until he was hanged.

Xiaoling said: "If Xu Fan hadn't treated her like a dog, she wouldn't have killed people out of control, but now she is happy that Xu Fan is dead."

Is it possible that for the sake of freedom of academic discussion, we can unscrupulously publicize the "evil" of willfulness? A sanctimonious professor like Xu Fan has ruined the body and mind of many students, and it is not a pity for such a person to die...
