Officer Wang touched his nose a little embarrassed and said yes.

I relaxed slightly, leaned my back back in the chair, and rested my fingers on my lap with my fingers.

"The psychological test usually has the GKT crime plot test and the CQT criterion question test, the GKT test consists of related questions and foil questions, while the CQT test consists of related questions and criterion questions, when people feel threatened, the vegetative sympathetic nerve will be activated, and there will be a series of uncontrollable physiological reactions, such as increased pulse, increased blood pressure, increased body temperature, dry mouth, etc.

The psychological tester is to collect the data of these physiological phenomena to determine whether to lie, because these are the stress responses produced by the human body, theoretically speaking, it can objectively reflect the psychological condition of the person being questioned. ”

With my words, Officer Wang's forehead sweated slightly.

"Some of the age and name questions you just asked me are to establish my normal level of reflection, so please try to get me to answer a "yes" question and a "no" question during the questioning process, otherwise there will be a slight deviation in the baseline setting during the whole polygraph process. ”

"At the same time, when you ask me questions about the case, you should try to control the pattern of the questions so that I can only answer yes or no, and I suggest that you should take the method of repeated questions, and each question only touches on one aspect, and use this cycle to determine whether I am lying or not."

Officer Wang reluctantly closed the document in front of him, glanced at the computer screen, and asked, "Can I know which question suddenly hit you?" ”

I was stunned for a moment, and found that my attitude just now was indeed suspected of being annoyed and overreacting, and in the face of Officer Wang's kind inquiry, I couldn't help laughing: "It should be the sentence you asked me if I believe there is a ghost." ”

"Why?" Officer Wang asked curiously: "Before I came, I paid attention to several cases you solved, and it can be said that each of them is a strange case, and these cases almost have a common symbol, that is, they look very much like supernatural events at the beginning. ”

I spread my hands and said very helplessly: "Probably fate, as you said, several cases I have handled are like this, sometimes I also think, why do I keep encountering these things, or maybe because of this, when you ask me if I believe that there are ghosts in this world, I hesitated, my reason tells me that there are no ghosts in this world, but when I first came into contact with the case, there are some phenomena that are really very suspenseful." ”

Officer Wang shook his head and smiled bitterly: "I kind of understand, if you want to lie, no one may be able to see that you are a person who can do things to the extreme, He Yang, I thought I had overestimated you, but I didn't expect to underestimate you, why did no one ever know that you had research in psychology?" ”

I told the truth: "There was no research, I just read a few books and listened to a few lectures. ”

"All I can say is that you're very talented in psychology."

The interrogation process was always long, and after a brief exchange, Officer Wang and I continued to ask and answer questions, and by the time I was finally able to walk out of the conference room door, it was already dark.

I leaned against the window of the hallway, pulled out the cigarette case from my pocket, and just put the cigarette in my mouth, a lighter suddenly reached out from the oblique stab.

I took a deep breath, and the smoke slowly came out of my nose, and through that layer of mist I saw Ye Huancheng with low eyebrows and lowered eyes.

"What the hell is going on?"

Ye Huancheng put away the lighter, the wind blowing in from the window lifted the broken hair on his forehead, and his eyes were as dark as the night sky.

"I don't know what's going on, but someone from above suddenly came and asked to test you."

"The test passed, and then what? I'm going to be a police officer again, a captain of the criminal investigation brigade? "My words were a bit sarcastic.

Ye Huancheng was stunned: "It's a consultant." ”

"What?"

Ye Huancheng emphasized again: "It's not the captain, it's the consultant, He Yang, you have passed the review, you will become the adviser of the police department, your authority is only under the director, and you are directly responsible to the director, that is to say, the entire police station, you have the right to interrogate any case, anyone, except the director, you can be transferred, including me." ”

With a cigarette in the corner of my mouth, I couldn't hide my surprise and straightened up and looked at Ye Huancheng, what he said was true, so, who is behind everything in the back?

"You really don't know who it is?"

Ye Huancheng's voice was heavy: "Of course, before you entered the conference room, I didn't even know what you were here for." ”

I flicked the paper in my hand with the seal of "approved" and the signature of Officer Wang, and suddenly felt good, took out the cigarette case in my arms and smashed it to Ye Huancheng: "Please." ”

I hurried to see Wang Qiuyue, who had been waiting for me downstairs, this was the police station, at least the security was a little stronger than other places.

When I was around the corner, I inadvertently glanced up and found that Ye Huancheng was still standing in place, looking down and couldn't see clearly.

At that moment, a thought suddenly flashed in my heart, if Ye Huancheng knew about today's review in advance, would he obstruct the review? He'll also let me ...... Become this consultant?

I went back to the police station, and naturally brought Lin Yi in, probably because of his special growth experience, he thought about the case from a very novel angle, but I didn't expect that a few days later, he really found new clues.

"Master, you see, it's this person, he said that he once saw Xiao Ling in close contact with a man."

Lin Yi took me to a warehouse, which was located in the factory owned by one of the deceased, and it is said that Sun Yun had a private intimate relationship with the owner of this factory, and Lin Yi accidentally learned when he was tracking down this clue that the warehouse keeper had seen Xiaoling enter and exit the factory.

"Dude, tell me in detail, what did you see?" I took a cigarette and handed it over, holding it between my two yellowed fingers, putting it under my nose and taking a deep inhalation in intoxication.

"Good smoke."

I lit a cigarette for him, and he squinted and took a puff.

It's a fucking old smoking gun.

Without saying a word, I took out another one and gave it to him, and he carefully put the cigarette to his ear, and when the smoke opened the way, he said in great detail, and did not hide it at all.

"This woman, her name is Xiaoling, I know, she is not a good woman, and she has unclear relationships with several men."

Hearing this, I frowned, and listened to the warehouse keeper say: "I have seen it with my own eyes, just some time ago, there was a man who came to the factory to look for him, I know this person, I used to work in this factory, and I don't know when I was mixed with Xiaoling." ”
