I looked up at him, a familiar face, but so unfamiliar. Who is he? Maybe I never figured it out. From the day he walked up to me, I was confused, but he wasn't. I bit my lip and didn't speak.

Lu Zenghan saw that my face was not good and was silent. He glanced around, saw the book in my hand, was stunned for a moment, picked up the book and flipped through it, and his face sank. He didn't speak, just sat next to me and took out a cigarette, but his hand seemed to tremble a little, and the cigarette fell, he slowly picked it up, hesitated, and put the cigarette on the coffee table.

Looking at the way he looked, he understood exactly what I was thinking, but he didn't say anything. Tears rolled in my eyes, and I looked up and held the tears in my eyes. I can't cry, my sister said, don't let the tears fall in front of the bad guys, you will only be laughed at by them. Is Lu Zenghan a bad guy? I don't know, but he is the one who mocked me fiercely in my emotional world.

My shoulders shrugged, I tried my best to suppress it, Lu Zenghan looked at me, his face was blue, he stood up suddenly, picked up the cigarette and walked to the window, smoked hard, looked out of the window, and looked out of the window with a solemn face.

Time seemed to freeze between me and him, and no one spoke. I got up and walked to the bedroom to pack my things, my mind was blank at that moment, I just wanted to get out of here, get away from him.

As soon as I pushed the suitcase to the bedroom, Lu Zenghan strode after me, clamped my arm, and said coldly, "Where are you going?" ”

I looked at him with red circles and swollen eyes, and my voice trembled: "You can go anywhere." Lest you be played with like a fool. ”

"I'm toying with you?" Lu Zenghan laughed angrily, "You said I'm playing with you?" ”

"What if it weren't?" I finally broke out, almost shouting, "Isn't the routine in this book your routine?" Pretty much the same, who the hell are you? ”

Lu Zenghan didn't speak, just pursed his lips and looked at me tightly, holding my hand and refusing to let go. I shook his hand away, only to feel my whole body tremble, and I rushed into the bedroom to continue packing. His silence is acquiescence, he is really attentive to me, and he follows the routine step by step from the beginning.

Lu Zenghan said with a cold face: "You don't have to go, I'll go!" After saying that, he strode out, walked to the door, and turned back sharply and said, "It's dangerous outside, so you stay here." Any opinions on me will be discussed in a few days. With that, he walked out.

The door slammed and I sat down on the bed, tears falling silently. The door didn't move anymore, and I lay on the bed, all wooden. My sister warned me not to give my sincerity casually, why didn't I listen? Why am I so confident that I can meet someone who is worth my giving?

I don't know how long the time has passed, but I feel that the surroundings are gradually quiet, maybe it is the second half of the night, and I have been keeping my eyes open until now. Suddenly my phone rang, and I glanced at it, and it was Katherine who had emailed me back. I got up and turned on the computer, for fear that my phone would not be able to see clearly.

Katherine told me in an email that the book "The Magic of Psychology" was written by her brother Jamson, and that the chapter I asked about was written by one of his students. The manuscript was his student's dissertation from five years ago, and he asked the student to make a slight change and add some new elements when the book was written last year.

I looked at the time, three o'clock in the morning, Kathrine was two o'clock in the afternoon, I saw in the mail that I was in a fog, and told me on the phone that the student was an exchange student of the Criminal Police Academy in Chinese mainland, and he studied criminal psychology with him five years ago, and he didn't know his real name, because it was all to be kept secret, only his English name was Harry. It was his dissertation, which was originally a study of criminals who deceived women, but when the book was published last year, in order to make the book more interesting, he contacted the student, made revisions, and added some psychological methods for pursuing girls. But after the book was delivered, the student could no longer be contacted and could not provide more information.

Hanging up the phone, I collapsed limply on the bed. Lu Zenghan is a police officer, has studied criminal psychology, and is also a master of psychology. No wonder, he is so good at speculating on people's hearts, so good at grasping the situation. No wonder he would make Zou Yukai obedient, how could Zou Yukai, who had autism, escape the routine of a psychologist?

The past replayed in my mind frame by frame like a movie. When Zou Yukai was sick and screaming on Nanqi Island, only Lu Zenghan could calm him down; I asked everyone to paint, but Lu Zenghan painted me, because he was already familiar with my art therapy and disturbed my mind, so he didn't even think to analyze his paintings; My hypnosis of him actually didn't work at all, but he pretended to be hypnotized and lied to the police that he surrendered because he was worried about Zou Yukai, but he actually wanted to ship it quickly...... When I have confidence in my identity as a psychotherapist, how many times have I been a pawn of him?

The human heart is really scary. I put the quilt over my face. Sister, why are people so complicated? I really can't tell.

I stayed at home for three days, and when I was hungry, I cooked myself a bowl of noodles, and my tears fell into the bowl as I looked at the familiar egg drops. In this world, is it only my sister who will not deceive me, and only my sister is the most true to me? But where is my sister at the moment? I wanted to hug my sister and cry, but I didn't dare tell her. I didn't dare to let her know that I had been deceived like this, and I was even more afraid that my smart sister would decipher more things that I couldn't think of. I'm a simple person, and I can't afford more scheming.

I was dizzy and didn't know that I had been like this for a few days, and suddenly the mobile phone rang, and Yang Yize called me in a hurry: "Teacher Xin, hurry, help." ”

Hearing his urgency, I asked, "What's the matter?" ”

Yang Yize hurriedly said in a hurried tone: "It's too late, let's talk on the road, you quickly tell me your address, and we will go to Zou Yukai together." ”

I didn't have time to ask, and was about to tell him my address, when I suddenly remembered that Lu Zenghan was afraid that people would know about this place, so I thought about asking him to meet him at the nearest pier. I casually changed into clean clothes and arrived at the agreed place.

Ten minutes later, Yang Yize's police car also came, and I was busy getting into the car. Ask him why. Yang Yize sighed: "I really can't think of this thing. Peng Zihao refused to say anything, and the case had reached an impasse. Last night, someone handed a piece of evidence to the criminal police team, and if I hadn't seen it with my own eyes, I would never have dreamed that there would be such a thing. ”

"What is it?" I asked, and Yang Yize's case pulled me back a little from my trance.

"A lead canister with a machine as big as hand. None of us recognized what it was. Later, the white team found experts overnight to see, and it turned out to be an infrasonic generator. Experts say that this infrasonic generator can produce low-frequency infrasound waves, adjust the frequency and intensity with the remote control, the light one can make people hallucinate, suspicious, and after strengthening the intensity, the frequency can be adjusted to the same frequency as the human organs, and finally make people's internal organs rupture. Yang Yize scratched his head, "You said that this kind of thing, even if it is placed in front of our eyes, I can't recognize it, let alone think that it can become a murder weapon." ”

"That is to say, this infrasonic generator is the murder weapon that caused Chen Chen's death?" I was stunned, and suddenly remembered that Lu Zenghan once took out something behind the mirror in the bathroom of Chen Chen's house and stuffed it into a bottle, I didn't pay attention to it at the time, but now that I think about it, is it the infrasonic generator? So when did Lu Zenghan know that the infrasonic generator was the murderer who caused Chen Chen's death? Thinking of Lu Zenghan, I shook my head desperately.

"Experts say it's possible. Infrasonic waves can rupture internal organs, but because Chen Chen fell from the building at the same time, it is impossible to determine whether the cause of her death was the fall or the effect of infrasound. Yang Yize said, "But seeing this infrasonic generator, Peng Zihao is not calm." Without waiting for us to ask him, he confessed that this generator was given to him by someone else, saying that it was placed in the house to make Chen Chen scared and explain something. But he had never seen a remote control. ”

The more I listened, the more confused I became, and my mind didn't turn now: "Then why should we go to Zou Yukai?" ”

He said that the person who gave him the generator was Zou Yukai's men. So early in the morning, the white team took people to Zou Yukai's house. Who knew that he was sitting on the roof of the building and refused to come down, and he was very emotional, and we were afraid that he would jump off, so we had to find a psychologist to persuade him, and the negotiators of the police force were all dispatched. Yang Yize said helplessly, "This Zou Yukai, what a strange temper, he doesn't cooperate with the police at all, in the previous few cases, whenever he was required to record a confession, none of them went smoothly, either silently, or yelling." Do you think he's sick? ”

I sighed and said to him, "He had autism as a child. I think you might as well find Lu Zenghan to help him. ”

Yang Yize sighed: "His father Zou Shizhao has already been found, but Lu Zenghan is not in Nancheng at this time, and he doesn't know what time it will be when he comes back." ”

I was stunned: "Wasn't it the infrasonic generator that Lu Zenghan gave you last night?" ”

"I don't know," Yang Yize frowned and said, "Someone called us last night and said that there was evidence at the door, and we went out and saw the box on the steps, and we didn't know who it was." The call was made online, and the source of the signal could not be found. The person who provided the clue was even more mysterious. ”

My mind was in a mess, I didn't prepare in advance, and I was not sure that I could persuade Zou Yukai again, after all, the last time Zou Shizhao asked me to persuade Zou Yukai, I was scolded by him, and he didn't accept my persuasion at all.
