"Nightmares?" I reminisced about it, that night I heard my sister's singing in a dream, and then ran out with it, and when I went back, Yingying told me that she also had a nightmare, dreaming that Yang Yize killed her with a knife. I didn't think it was anything at the time, but in retrospect, it's really unusual. I asked Lu Zenghan: "Did you deduce it from these details?" ”

"Dreams are a very interesting thing." Lu Zenghan looked at the distance with a leisurely expression, "I took a course when I was in college, which was about metaphysics. ”

"Metaphysics?" I don't understand, I haven't studied it, I'm just curious that this kind of feudal superstition can be used as a university course, "Will this kind of class be allowed?" ”

"Absolutely. This lesson is to explain some strange phenomena with scientific principles. For example, the corpses in Xiangxi, such as ghosts hitting the wall, and for example, seeing ghosts. Lu Zenghan explained, "In some old houses, there will be some strange figures and the like, and then they will be declared haunted by gods. I remember that the teacher explained this supernatural phenomenon at that time, because there are low-frequency infrasound waves in those places, if the frequency is close to 18 Hz, it will cause the eye to resonate, and the frequency required for eye resonance is 18 Hz. ”

"It's the first time I've heard of such a novel explanation." I shook my head, full of curiosity. The phenomena of this world are very strange, and the ghosts and ghosts have always been a blind spot that I can't believe but can't explain, and now that he says this, I have a feeling of sudden enlightenment.

"So the so-called hell is just a resonance of human eyeballs and low-frequency infrasound waves. Chen Chen's hell was because he put an infrasonic generator behind the mirror in the bathroom. But infrasound can give people nightmares in addition to making people hell. Because low-frequency infrasound waves can cause people to be frustrated, sad, fearful and other emotions. When people are asleep, they receive low-frequency infrasound waves, and under the influence of these emotions, they will naturally have nightmares. "Lu Zenghan said it in an orderly manner, and I could listen attentively.

I couldn't help but ask, "Do infrasound waves still affect emotions?" ”

"Of course. A foreign psychologist once did an experiment, adding low-frequency infrasound waves with a frequency of less than 20 hertz to four pieces of music during piano playing, and the audience all felt sad and uneasy after listening to it, which is very similar to the feeling of being haunted. Lu Zenghan said very firmly, "So in addition to eye resonance, hauntings also have psychological and emotional feelings of fear and anxiety because of infrasound." ”

"But," I still wondered, "why am I different from the ghost Chen Chen sees?" "She saw women, and I saw men.

"This question," Lu Zenghan said lightly, "I'll tell you later." ”

I looked at Lu Zenghan's eloquent talk, and I really wanted to open his brain to see what it was made of, how could it hold so many things, it was military blasting and infrasound. And the main line of the case can be deduced from the subtle side details. I asked again: "Then did you suspect Zou Yukai at that time?" ”

"Nope." Lu Zenghan replied simply, "I was only thinking about shipping as soon as possible, and I didn't think about it so much." After returning to Nancheng, I was locked up for a few days, and I was idle, so I thought about the cases before and after, only to find that many of Zou Yukai's performances were very unusual, such as he would run downstairs in the morning, and Xiao Yanbing would wear that ugly raincoat at the same time as he ran downstairs. Only if Xiao Yanbing is controlled, will he make that kind of move that is impossible on weekdays. Thinking about the nightmare that night, many people in the villa mentioned that I had a nightmare, and I happened to be outside at that time, and suddenly I felt a little uncomfortable, sad and lost, so I walked outside your development center. At the time, I thought it was just a sudden emotional attack, but after thinking about it, I felt that something was wrong. ”

"Oh." I was slightly disappointed that I had deduced that he had been following me outside the development center that morning, and I was a little moved, but now I know that that that touch was just a beautiful accident. I looked into the distance in embarrassment, not knowing whether to sour or hurt. After a while, he sighed: "Zou Yukai is really unseemly, he looks like a simple and quiet teenager on the surface, how could he partner with He Xiaomin's father to kill people?" ”

"He's simple?" Lu Zenghan sneered a few times, "In order to ship as soon as possible, he can pretend to be a murderer and cut himself to blood, is he simple?" ”

"You mean, his wound—" I covered my mouth in surprise, "I cut it myself?" ”

"He and He Jiangang were wearing a pair of pants, how could they be cut by him?" Lu Zenghan shook his head, "I saw at that time that his knife wound was cut by himself, but I just didn't say it." Zou Yukai is a very thoughtful person, and I never dare to treat him as a clear teenager. Lu Zenghan's voice was a little sneering, which made me feel ashamed, I still look at people after all. Although I can see people's mental illness, I can't see the uncertainty of people's hearts.

I changed the subject awkwardly: "But is there any evidence for Zou Yukai and He Jiangang's murder on Nanqi Island?" Zou Yukai is dead, He Jiangang will definitely not confess Zou Yukai. ”

"The last time we went to Nanqi Island to look for evidence, I took some plant samples from the back of Yunhu Villa, and there was a kind of leaf with messy spots. I brought it back to a professional for testing, it is a kind of grass that is very sensitive to infrasound, and the action of infrasound waves will cause changes in the tissue structure inside, and disordered apoptosis will occur, which is manifested in the leaves as burn-like spots. Lu Zenghan hooked his lips and smiled, and said with determination, "Fortunately, it has only been a few months, and if a growth period has passed, there will be no evidence again." ”

I breathed a sigh of relief, if this evidence is handed over to the police, Zou Yukai can be convicted, although the person is dead. I asked, "Can you give the police all that evidence?" ”

"Whatever you want." Lu Zenghan said, "There are still leaves on Nanqi Island, just let them find them." After saying that, he stood up, "Go back." ”

From the case to reality, my heart pounded twice, I didn't know what to do, just silently followed him. Zou Yukai's case is over, but what about Zou Shizhao? Will he let Lu Zenghan go? I glanced at Lu Zenghan's back a few times worriedly, and sighed helplessly.

Back at home, Lu Zenghan simply packed a few clothes and said to me: "It's almost the New Year, and it's hard to find a house in Nancheng." You live here first, think about it, I'll go live somewhere else first. After saying that, he simply left.

The room was empty and I was left alone, and I curled up on the couch with my knees crossed. What am I going to do? What is he like? I do need time to think about it.

The New Year is getting closer and closer, and the Spring Festival in Nancheng is very grand, and there are people everywhere who are busy making New Year's goods. As in previous years, I was still at a loss and didn't know how to prepare. My sister was with me on Chinese New Year's Eve last year, and I don't know if she will come this year. I sent her a WeChat message: "Sister, are you coming to Nancheng for the Chinese New Year?" ”

My sister replied to me, "There is something to do on Chinese New Year's Eve." I should be able to find time to see you back in the future. ”

I hugged my phone and breathed a sigh of relief, but it didn't have the joy of the previous years. I miss my sister very much, but this year I seem to be a little afraid of her coming back. I'm scared what she'll reveal when she comes back. But I didn't dare ask.

It's just that I'm alone for the Spring Festival, and I'm destined to be very lonely. A few years ago, it was either Han Muzhi or my sister, there was always someone by my side, and this year there is no hope. I spent all my time in the clinic. Yingying sometimes came to see me and helped me with something. She is going to take Yang Yize home for the Spring Festival, and she will hold a wedding after the New Year. Looking at her happy and delicate appearance, I can't say anything with envy.

Yingying dragged me hard, and she had to go to the supermarket to buy a bunch of food and drink, and buy some lanterns for home decoration before she stopped: "But Sister Qiao, my brother can't accompany you for the New Year this year, his mother is sick, and he wants to go back." But no matter what, we must also celebrate the New Year with joy. At least give the next year a lottery. ”

I smiled faintly, and if these could really be a good idea, I wouldn't mind dressing up my home with lights. It turns out that when people are hurt, they really need sustenance in their hearts.

When there were still three days left on Chinese New Year's Eve, except for the merchants, there was no one at work, and the two assistants of the clinic took leave to return to their hometown for the New Year, and there were no visitors to make an appointment, so I had to sort out the information and read books in the clinic. It's really the hardest day, and I've never felt that the festival is such a bleak thing. Especially in the Spring Festival, which is the most important festival for Chinese.

I didn't go back until late at night in the coffee shop, and as soon as I walked out of the door of the coffee shop, a man stood in front of me: "Mr. Xin, Mr. Zou is invited." ”

At this moment, my hairs are almost standing on end, and Zou Shizhao will never do anything good looking for me now. He and Lu Zenghan have torn their faces, what else do they need me to do? But how can I resist? I had to silently follow the man into the car, and in the car, while he was not paying attention, I secretly pressed Lu Zenghan's phone. It's just that before it sounded, it was discovered by the man next to him. He quickly snatched the phone from my bag, turned it off and threw it back into the bag, warning me, "Teacher Xin, don't play this game." Mr. Zou has been in a bad mood recently, don't do these things to find death. ”

I didn't say anything. I couldn't tell where I was going, not to his old mansion or to his villa, but to the dock. Sure enough, in less than half an hour, the car stopped at the dock, and the man pushed me onto a boat, and I staggered up, which was not a yacht, but a slightly dilapidated cargo ship, large, very old.

I walked into the hatch, which was large, but covered with a canvas, and I didn't know what was inside. It was very dark in the cabin, and I walked for a long time before I saw Zou Shizhao's back on a chair at the bow of the boat. I haven't seen him for more than 20 days, and he seems to have been hollowed out, his whole person is a little rickety, and his hair is almost white.
