Ling Qingfeng pondered the treasure content taught today, and at the same time used his hands and feet to climb to the top of the cliff.

After returning to the dormitory and changing clothes, Ling Qingfeng Yinuo came to the No. 1 teaching building. Donald's criminal psychology classroom is located in the multi-purpose hall on the first floor.

I just finished meeting in the morning, and now I have to face to face again, when I think of this, Ling Qingfeng is a little unrefreshed, and the most important thing is that his mind is now full of three-point piles, squatting horse steps, gossip knives, how can he have the heart to take a psychology course!

Although he complained a little, Ling Qingfeng still pushed open the classroom door and walked in.

Good guy, no wonder Donald let himself support the scene. As soon as the class bell rang, there were only a few people sitting in the class, and the seats in the back row were empty, and no one would come to such a peerless class so early in the morning!

Ling Qingfeng found a place in the second row to sit down, next to him was a boy who was sleeping on the table, and the corners of his mouth were almost flowing to the table.

Sure enough, the Huoyun Evil God happily took the lesson plan and came to the big classroom in a hurry.

This old man didn't bring his own pork ear rice to class since he ate the cold pork ear prepared by Ling Qingfeng in the morning, which has improved a lot, at least he won't use his big oily hands to brush the few pitiful hairs on his forehead. The picture was so beautiful that everyone couldn't bear to look at it.

"Hello students! Today, the teacher will tell you about the three-stage reasoning technique! Its basic principle is that one and two are the base, and the third paragraph must be hit! ”

"One paragraph, a man will die!"

"Second paragraph, Socrates is human!"

"Three paragraphs, so Socrates will definitely die!"

"Do you understand?"

After the Huoyun Evil God finished speaking on the podium, the students below were stunned and didn't know why. Who knows what he's talking about?

Actually, the evil god of the fire cloud is talking about an example of a syllogism argument that Aristotle once cited, but he said it too directly, and it was completely a cramming method of education, no wonder the students below couldn't understand it.

"What is this old man talking about?"

"I don't know! He's always been so chattering, I heard that he has a lot of research in psychology, huh? Why is the stuff so blunt, it's not good! ”

"It's okay, you will get credits when you come to his class, and you can go out at any time anyway."

Ling Qingfeng heard the discussion of the other students, and felt sad for Tang Lao, this old man is a good hand at teaching martial arts, but the level of teaching professional classes to students is really not very good, maybe he has studied too deeply in academics, as soon as he opens his mouth, he treats students as professionals, and does not consider the problem from the perspective of the audience and user experience at all.

"Well, I'd better help him!" As soon as Ling Qingfeng had a thought, he immediately adjusted from his squatting posture and stood up straight.

When the student next to him saw Ling Qingfeng standing up, he thought that there was another one who was leaving, and even deliberately moved his butt to make way for him.

Ling Qingfeng coughed lightly and said loudly, "Teacher! I've heard of syllogism, which is a method of reasoning that is often used by the FBI, can you tell us a case first? Everyone participates in interaction and discussion, and I believe it will be easier for everyone to understand. ”

As soon as Ling Qingfeng spoke, he first mentioned the FBI, that is, the famous FBI of the United States, which immediately attracted the interest of the students present.

The ears and eyes of the Fire Cloud Evil God were so sensitive that they could sense the change in the atmosphere in the classroom at once, and the students' attention began to focus!

He reacted immediately, followed Ling Qingfeng's words, nodded and said, "Okay!" This classmate reminded very well. Let me first tell you about a case restoration.

In the desert area of the Chinese border, someone found a man dead in the desert with his head stuck upside down in the sand, and there were several suitcases scattered around him, but his identity documents, including ID cards and passports, were complete, and his belongings had not been touched. The only thing that makes people strange is that the deceased is holding half a match in his palm, and he is clenching it tightly, so may I ask, how did this person die? ”

It sounded ridiculous, but there seemed to be no connection between the several clues raised by the Fire Cloud Evil God, so how could it be possible to deduce the cause of the deceased's death?

For a while, all the students in the audience fell into thinking.

Soon, a small boy with round glasses stood up and replied: "Someone killed him and stuck his head in the sand, it is a cult ritual, and the other party does not covet the money of the deceased, because only a cult would do that!" ”

"How do you explain that half a match!? I think it's clearly a love killing! The identity of the deceased is obviously the legendary Lao Wang next door, after he was killed by his rival, the other party stuffed half a match in his hand, which means that the adultery between you is like a match, although it is hot, but it will not last long, and it will eventually be extinguished! ”

This time, it was a girl in a black dress who stood up and spoke, with a cold expression, and seemed to grit her teeth a little when she talked about adultery.

Depend on! This sister must have been injured and left tears for the, her brain hole is so big, she should be recommended to go to the starting point to write novels, and she will definitely make a lot of money!

Hearing more and more garbled answers, the Fire Cloud Evil God was in a good mood, this was the first time that so many students had responded to their questions in class! As soon as he thought of this, he couldn't help but cast a grateful glance at Ling Qingfeng.

"Ling Qingfeng, what do you think?" The Evil Myth of the Fire Cloud turned around and threw a question at the class.

Ling Qingfeng frowned and replied, "I haven't figured it out yet, I just think we have to reason from the way the deceased died, why did his head fall upside down into the sand, I don't agree with the statement that cults kill people, because this kind of case is too special!" It's like taking credit to aliens for writers' habit of attributing anything that can't be explained. I think there is probably some more reasonable connection between the inverted plug and the match, but we can't think of it for a while! ”

Hearing the Huoyun Evil God shouting Ling Qingfeng's name, and seeing his eloquent appearance, the students sitting in the classroom let out a buzzing discussion.

On the spot, someone took out his mobile phone and used WeChat to send messages to his best classmates.

"Little sister, come to the big classroom, haven't you always wanted to see Ling Qingfeng? The real thing is here! Come on! ”

"Your Royal Highness Ergou, Li Xia's rumored boyfriend Ling Qingfeng is in the big classroom, I have read it, it's very handsome! You're basically out of play, don't accept it! ”

"Brothers of the Xueba group, half of the pig-eared ghosts are finally worried today, talking about the FBI's god-level reasoning technique, don't regret it!"

There are also people who directly took photos of Ling Qingfeng from various angles in the classroom, and posted a circle of friends casually, with the title being a thief, "Half of the pig-eared ghosts are worried about the war and the missing newcomer Ling Qingfeng, a wonderful moment, not to be missed!" ”

So, in the process of Ling Qingfeng's conversation with the Huoyun Evil God, students slipped in one after another through the front door and the back door.

Some came to see the handsome guy Ling Qingfeng, some came to see the mysterious boyfriend of the school flower Li Xia, some came to see the half of the pig ears vs. Ling Qingfeng, and some were purely engaged in the fun and soy sauce.

After a while, the classroom was actually full of students who rushed to hear the news, and even the guys standing outside the window and by the door were full of probes and brains.

Perhaps because of the recent calm in the school, as soon as there is any wind and grass, all these energetic animals will come.

The Huoyun Evil God was directly excited, he had led a class for two weeks, and there had never been so many students at one time. His self-esteem was greatly satisfied, and the pleasure of being a good teacher was once again released.

He knew very well that all of this was brought by Ling Qingfeng's kid. The cooperation between himself and him in the classroom is like the horns and comics in cross talk, some people praise them, some people lift them, their self-confidence is bursting, and their state is naturally different!

"Ling Qingfeng is right, this is the prototype of the three-stage reasoning technique. How did this die? Let me use the three-stage reasoning technique to make a case reasoning for you.

The deceased died in the desert with his head stuck upside down in the ground, a posture that was often accidental. As Ling Qingfeng just said, then, what is the reason for this accident? The answer is simple, it's a plane crash!

The plane in which the deceased was flying over the desert and he fell from a high altitude, and the suitcases around him were supposed to be the suitcases of the deceased.

Then, one stage of thinking is that the deceased falls from a high altitude above the desert, the second stage of thinking is that the deceased's suitcase is scattered around, and the third stage of reasoning is that the deceased and the suitcase fell almost at the same time.

Generally speaking, when a person dies, what he holds on to is very important, and it is likely to be the clue to the cause of his death. For example, in the TV series we saw, a strand of hair or a red rope or something held by the deceased was often picked up by the deceased on the murderer's body. Of course, our domestic dramas with hand-tearing devils are not among them, you all know it! ”

Huoyun Evil God also had a rare humor, mentioning the domestic drama, which made the students in the audience laugh.

"To get back to the point, according to this line of thought, let's assume that half of the match in the deceased's hand is the murderer who caused his death, according to the three-stage reasoning technique, what do you have good ideas?"

Analyzing this, Ling Qingfeng's heart moved, and he blurted out: "I guessed!" Why half a match, and not a match. Because half a match is used to draw lots, it is signed, so there is only half a match! He won the lottery, and was unlucky enough to jump from the sky, so he fell headlong into the sand! ”

"Very good! This student's thinking is very clear, and he is basically close to the logic of the syllogism! Let's sort out the clues, the first paragraph of thinking, the deceased drew half a match, the second paragraph of thinking that the deceased fell from a high altitude, and the conclusion of the third paragraph was that because of some kind of accident, the deceased was forced to fall from a high altitude, then the problem came again, if it was an airplane, it was basically impossible for this situation to happen, there was either a parachute on the plane, even if the umbrella was not enough, it would not fall with luggage, the flight speed of the plane was very fast, and it was difficult for people and luggage to fall in one place. In other words, according to our reasoning, this flying machine is not that fast! ”

"I see! The deceased was riding in a hot air balloon, and the most common high-altitude aircraft in the desert was a hot air balloon, so in fact, the deceased and his friends took a hot air balloon together, and encountered a malfunction, resulting in insufficient power to lose weight, and then they used matches to draw lots, and the deceased drew the lot, jumped off, and he was holding half a match in his hand that caused his death! ”

The answer that Ling Qingfeng blurted out was immediately exchanged for a warm applause.

Of course, the cadets of the police academy have the highest sensitivity to the profession of the police, and such a wonderful case analysis gradually unfolded in the dialogue between the teachers and students, and finally came to a conclusion.

There is no need for the Fire Cloud Evil God to judge, all the students present already know the answer very clearly. They applauded together, not because Ling Qingfeng answered the correct answer, but because they knew how to appreciate, appreciate people who are better than themselves, and appreciate people who can come up with answers one step ahead of others.

Everyone felt that it was worthwhile to hear the lecture, so they applauded excitedly.

The Fire Cloud Evil God was also slightly surprised, he didn't expect Ling Qingfeng's mind to react so quickly! This kid is not only good at martial arts, but also has a good brain, and he was born to be a policeman! (To be continued.) )
