"Hello, did you tell our police that this man didn't commit suicide?" At the police station, a policeman who was a little over 180 tall, with a board-inch hairstyle and a denim T-shirt, brought a glass of water to Qin Yan who was sitting on a chair: "I am the captain of the Municipal Criminal Investigation Detachment, and my name is Gu Chengyu." ”

"Thank you, Captain Gu, my name is Qin Yan, and I am the person in charge of the 'Destiny' psychological clinic and the part-time attending physician. I'm a psychologist, so I could tell that this person was hypnotized before jumping off a building. Qin Yan took the water cup, drank his saliva and said.

"So what the hell is going on? Can you explain it in detail?" Gu Chengyu asked very carefully.

"That's right, can you give me a replay of the surveillance footage from the scene?"

"Absolutely. With that, Gu Chengyu moved a laptop that was being used for a live video return visit to Qin Yan's side, and said, "Look, what can this video illustrate?"

"Please pause here. Qin Yan said. The picture at the pause was the picture of the man just climbing over the fence, Qin Yan pointed to the man's face and said, "Look here, magnify the victim's facial expression." ”

Gu Chengyu enlarged the man's facial expression and said, "What can you see from this?"

"Captain Gu, pay attention to his expression, his facial expression at this time is very numb, without the slightest change, and one thing I need you to notice is that since this person appeared in the surveillance video, his eyes have been in a half-open state that is not completely open, and from this period of time in this camera, his eyes have never blinked. Qin Yan said.

"Mr. Qin, is it possible that this person is a patient with severe depression?" Gu Chengyu said.

"Captain Gu, no way, a person with major depression will feel that death is a relief when they lose the motivation to live, and they will laugh the moment they jump. But you see, this person has always maintained this expression when he came to the scene of your corpse collection, and there has been no change at all. So I ruled out suicide because of major depression. Another possibility of suicide is an emotional breakdown, but people who have an emotional breakdown usually hesitate when jumping down, that is, there will be a pause, and they actually want someone to pull them at the last moment. But this person, you see, the process of jumping down is done in one go, without any hesitation at all. Qin Yan analyzed: "So I said that this person belonged to him to kill, and he was hypnotized." ”

"Then Doctor Qin, are there many people who can do such hypnosis?" Captain Gu said.

"In fact, in the profession of psychiatrist, hypnosis is actually a skill with a wide range of applications. We psychologists use hypnosis so that we can learn about some people's true past and some things they are hiding from their hearts. But the hypnosis of this victim is more advanced. This kind of hypnosis is the highest level, and now only my teacher, Professor Wang Qiujie, is known, but Professor Wang has always been very upright and has never done anything against morality or even the law. Qin Yan said, there was actually a little doubt in his heart - it wouldn't really be his own teacher.

"Okay Doctor Qin, thank you very much for your analysis of our case, but what do you think of the other case, which is the corpse in the model airplane. Captain Gu asked.

"Actually, it's hard to say, it's possible to say that they are related, after all, in that shopping mall, there are a total of three patios, and the patio at the scene of the crime is not the most trafficked. According to the perpetrator's idea, there is a better model of the airplane in the very center of the patio, unless the model has some special significance. Also, don't you think the locations of these two cases are a bit too coincidental?" Qin Yan said.

"It's true that the two cases happened too coincidentally, but the modus operandi of the two cases is completely different. Captain Gu said.

"Captain Gu, if I were the murderer, I would definitely disguise the two cases as two unrelated cases, so that it would be more difficult for you police to investigate, and he would have more time to do more things, such as killing the next person. Qin Yan said.

"Then Doctor Qin, are you presumed that these two cases were the work of one person?" asked Captain Gu.

"No, I'm just speculating, but the main thing is to see your investigative methods. Qin Yan said.

"Thank you very much, and I hope you can assist us in investigating this case in the future. Captain Gu stretched out his hand and shook it with Qin Yan. At that moment, I felt Captain Gu's true feelings and trust with my own eyes: "Captain Gu rest assured, if necessary, he will not hesitate." ”

Qin Yan left the city police station, only to find that Ding Chen was already waiting for him at the door in a car. Seeing this, Qin Yan said angrily: "Lao Ding, you are really, can you still see this scene? This must be a lot of stimulation for her, you should go and accompany her at this time!"

"It's okay, I'm still asleep, and before she fell asleep, she told me that I must come to the police station to pick you up. I'm afraid that it won't be good if you get revenge from the murderer. You see, I was a soldier, and my physique is not bad, so I can be your bodyguard. ”

"I said, who did you learn this calf kung fu from, old Ding。。。。。。 Qin Yan laughed so much that he almost spoke out of breath: "Lao Ding, have you forgotten that I was the coach of our school's free fighting team when I was in college? ”

"Old Qin, Tiezi, you won't give me face!" Ding Chen said.

"Hey, let's talk to whom, right? So you'd better go back and stay with me, I'm just alone here. Qin Yan said with a smile.

"So, what did the police say?" asked Ding Chen.

"I don't have anything to say, but I personally feel that this matter may have something to do with the teacher, so I really don't want the teacher to be involved. Qin Yan suddenly became serious.

"So you're ready to cooperate with the police investigation?" asked Ding Chen.

"That's right, I'm going to find out the murderer, and I can be regarded as cleaning up the door for our industry. After all, this person has a more or less relationship with my teacher, and maybe his next target is a teacher. Qin Yan whispered, for fear that what they said would be heard by the third person.

"So what are you going to do next?" Ding Chen asked.

"Go see my teacher, I'm going to be hypnotized once, you are next to me to record it, I want to know what I look like after being hypnotized and whatever. Qin Yan said, so the two drove to Professor Wang.

Professor Wang seemed to know that Qin Yan would come to him today, and when Qin Yan entered the door, Professor Wang was waiting for him: "I guess why you came to me today, it's for the matter of the shopping mall jumping case." ”

"The teacher is really the teacher, and he is still like a god. Qin Yan said: "Who else can do hypnosis implantation now besides you?"

"I don't really know who can do it in City B except me, at least among the old professors of my generation, I can do it. Professor Wang shook his head and said.

"Teacher, let's do it, you hypnotize me, I want to know how I look after being hypnotized, and determine what kind of point this murderer can go. This is my good brother Ding Chen, he will record the video on the side for a while, don't worry, teacher, the video is for my own use, and it will not be passed on. Qin Yan said, "Please, teacher." He bowed.

"Qin Yan, it doesn't have to be like this, I'll give it a try, now, imagine your favorite scenery and tell me what's in the scenery。。。。。 In less than 20 sentences, Qin Yan was hypnotized, and at this time, Ding Chen asked beside him: "Teacher, can Lao Qin open his eyes after being hypnotized now?"

"Theoretically speaking, people with weak normal psychological defenses will be directly influenced by me, and he will do whatever I ask him to do. But Qin Yan is professionally trained, and his psychological defense line is far superior to others, and it is not easy for me to hypnotize him. Professor Wang shook his head and said, after which Professor Wang woke up Qin Yan.

"Qin Yan, in fact, I have seen the victim, it should have been more than half a month ago, he came to me, but he didn't come to me, he came to find Tiancheng. But if Tiancheng is suspected of this, I don't believe it, after all, he can't hypnotize at all. Professor Wang said.

"Okay, Professor Wang, thank you, I'll ask Tiancheng. Qin Yan nodded, said goodbye to the teacher, and walked out of Professor Wang's office.
