As if seeing my doubts, Senior Sister Mu Mu lifted some of the white cloth on his body, pointed to Wang Dongcheng's lower body and said, this child was not strangled to death, although it was suffocation, it was a more curious way to die.

Senior Sister Mu Mu stated in a very plain and calm tone that among the types of suffocation death, there is a saying of sexual asphyxiation, which is a relatively rare type. But the principle is very simple, and it is the same principle as pouring car exhaust in a car and burning charcoal in a closed house.

In a confined space, as the oxygen breathed becomes scarcer and the carbon dioxide increases, at the end of the day, it becomes impossible to breathe in oxygen, and what happens after that is obvious - gradual suffocation.

Senior Sister Mu Mu said that the process of suffocation is more painful among various ways of dying, because in a confined space, oxygen disappears more slowly than people think.

When the human body is facing death, it will secrete a lot of adrenaline, relying on instinct to delay the time towards death as much as possible. So in general, people who are ready for suicidal consciousness will swallow a large amount of sleeping pills and suffocate themselves to death in this way.

In this way, you can alleviate your own pain and die in a state of near unconsciousness. However, sexual asphyxia is not the same as car exhaust suffocation and charcoal suffocation in a closed room.

It is said that the tragedy of death due to sexual asphyxiation is generally more common in Europe and the United States, which are more open and bold, and China is a relatively small type. The reason for this is also very simple, although it seems perverted to the average person, the feeling of sexual asphyxia is addictive.

Senior Sister Mu Mu said that when people are hypersexual, it is not the physical body that reacts, but the central nervous system of the brain must be stimulated first, so as to produce a response. And the stronger this feedback response, the same doubling of the pleasure.

Sexual asphyxia can multiply this pleasure several times, and the person who experiences it at the time can be very exciting and fluttering, but this also comes with great risks. One is that it is easy to be in a suffocating state before it can be relieved of the suffocation state, and then die unexpectedly.

On the other hand, this state of asphyxia is likely to destroy the central nervous system of the human brain, for example, after many attempts, the feedback system of the central nervous system has an organic abnormality, resulting in general stimulation can no longer produce hypersexuality.

And this is also the key reason why sexual asphyxia is addictive. Senior Sister Mu Mu said that according to her test, sperm spots were found near the place where Wang Dongcheng died, and sperm spots were not only from Wang Dongcheng himself, but also from other men's DNA was adopted and found.

Judging from the scars on his body, it is estimated that Wang Dongcheng was forcibly suffocated to death. In other words, it is likely that this was a murder, not an accidental death caused by Wang Dongcheng voluntarily enjoying this perverted pleasure.

Senior Sister Mu Mu said that the practice was probably to put a plastic bag on Wang Dongcheng's head to put him in a suffocating space, until finally, Wang Dongcheng instinctively struggled and wanted to get out of the suffocation state, but he couldn't resist at that time, because he should be in a state of being abused by a man.

I listened to Senior Sister Mu Mu silently finish speaking, and couldn't help but ask, can the person who killed Wang Dongcheng be found? Senior Sister Mu Mu said that it was not a big problem, because DNA had been collected from the sperm spots, and the rest was to search for a wanted warrant. I asked if the police had intervened in this matter, and Senior Sister Mu Mu said of course, and it was even the criminal police team that intervened.

Lin listened the whole time, and didn't ask questions, which is not like Lynn's style, and I think she should be more active in asking questions than I do.

"Senior sister, thank you for informing us about this."

When it was time to leave, Senior Sister Mu Mu sent us outside, and Lin and I expressed our gratitude to Senior Sister Mu Mu. She took out a box of ladies cigarettes from her pocket - I was shocked, and said Senior Sister, you still smoke?

Senior Sister Mu Mu smiled and said, I don't have an addiction to smoking, but the smell of corpses will stay in the nasal cavity for a long time, so use the smell of smoke to fight poison with poison. I understand it very well, because I only stayed there for more than 20 minutes, and I felt a little unbearable, and I was still wearing a special mask.

The senior sister said that the corpse is good for everything, but the smell is not good, and it is difficult to remove it after staying, sometimes staying for a day or two, nothing works, whether it is a mask, smoke, or brushing teeth, it can't completely remove the smell.

I said sympathetically, otherwise you wouldn't do this, senior, why can't you do it with your talent? Senior Sister Mu Mu smiled and said, it's okay, now I can get used to it - I found a rose-flavored cigarette some time ago, and it tastes great to smoke.

Senior Sister Mu Mu walked on this road, let alone me, her whole family couldn't convince her, I was quickly relieved, and after asking Senior Sister Mu Mu about the time to go home, I returned home with Lin first.

After eating in the evening and going back to their respective houses, there was an unexpected gain. I received a text message from Li Xiao. She asked me if Wang Dongcheng was really dead? I asked her how do you know, and then Li Xiao didn't reply at all.

In the middle of the night, the mobile phone rang suddenly, and I rubbed my eyes and found that it was a call from Senior Sister Mumu. I was immediately stunned. Thinking about when is this, Senior Sister Mu Mu still jokes with me.

On the spot, I turned on the lights and was about to go to Sister Mumu's house and knock on her door, but as soon as I got out of bed, my steps stopped.

"Wait a minute...... Senior Sister Mumu...... Didn't you come back? ”

Thinking of this, I immediately had a bad premonition, and hurriedly picked up the phone and picked it up, and the voice of Senior Sister Mu Mu immediately sounded on the other side, although I was very anxious, but I was relieved. Thankfully, it wasn't anyone else who answered the phone.

"Senior sister, where are you now? Didn't you come home? I hurriedly asked.

"Nope! I didn't go home, but it doesn't matter now! Small hanging! The body of Wang Dongcheng of the forensic appraisal center is gone! ”

“…… What the? ”

I was stunned for a moment, and then Senior Sister Mu Mu almost cried and told me that she had been checking Wang Dongcheng's body in the house since I left. But just now, she felt like she had stayed too long and wanted to go out for a cigarette and relax.

As a result, when he returned to the house after smoking, he found that Wang Dongcheng's body was gone. The round trip took less than ten minutes. And Senior Sister Mumu said that when she went back, she hardly saw anything strange, not even a ghost.

Unlike other places, the lights are on almost 24 hours a day, so there are no dark corners. She went to the monitoring room as soon as possible, but it happened that there was a problem with the machine in the monitoring room, and when she went, the screen was always black.

And I only recovered ten minutes before I called. But this recovery doesn't matter, Senior Sister Mu Mu said that after the monitoring room was restored, she found that in the room, there was a small note on the bed where Wang Dongcheng was lying.

"A little note? In those ten minutes when the monitor screen in the monitoring room went black? ”

"No, to be exact, in the few minutes I went to the surveillance room to make sure the surveillance was ......"

I couldn't help but gasp - for a few minutes, I was unconsciously shuttling through the forensic center, which ...... Is it really something that people can do?

In my mind, the content of the third task became clear online, even with a slight chill.

"Senior sister, did you read what was written on that note?"

When I asked, Senior Sister Mu Mu fell silent, and a depressing silence surrounded me, making people feel inexplicably uneasy.

“…… Senpai? ”

After a long time, Senior Sister Mu Mu said a little hoarsely: "Well, I went to look at the note...... Write the content. ”

"Okay, what's written on it?"

"Little hanging...... I hope you're not surprised to hear it—it says, your name, and, Rin, Dongzi, and mine. ”

After that, Senior Sister Mu Mu took a breath and continued: "After writing the names of the four of us, there is also a sentence written at the back - don't meddle anymore, give you the last three days, and get out of Shenglan for me...... Otherwise, let you die. ”

I thought, I'm such a useless guy, useless to the extreme.

Just a sentence, the contents of a small note. At this moment, my heart is racing, my eyes are swollen, my ears are hot, and my brain is shaking. Senior Sister Mumu's worried inquiries were mixed with slight tinnitus in her ears, forming a sound similar to auditory hallucinations.

I'm standing in my room right now, but I'm having a terrifying delusion - is my room really where I am? Could it be somewhere else? It's just that the decoration of this house is exactly the same as my room?

After opening the door, will it be the hallway I am familiar with, or will it be endless darkness? Or...... Will it be Wang Dongcheng's home?

I don't know what's wrong with me, this strange thought is like mushrooms after a rain, crazy expansion, and I can't stop it at all. Fear crept through my mind and began to take on a substantial form, which left my mind blank.

I have to admit that I'm a little broken now.

And at this moment, I heard footsteps, and then that footfoot, stopped at the door of my room. There was a soft knock on the door, and after a moment's pause, the door creaked open slowly.

I could feel my breathing getting heavier and heavier, even trembling, my eyes gradually widened, my pupils contracted violently, and I felt that the more I breathed, the more I couldn't breathe in the air, and I began to feel dizzy in my brain. I have a gut feeling that this door cannot be opened, absolutely not......

However, it was Lynn who walked in, and she was stunned at first when she saw my face, then hurriedly walked over and slapped me hard in the face, and then reached out and pulled my arm away.

"Hah...... Ha ......"

In fact, the moment Lynn walked in, I already knew what I was doing.

"You...... What the hell are you doing? ”

Lin looked at me blankly and couldn't help but curse angrily. I knew what I was just doing - I was trying to strangle myself alive, and I did it naturally, without any resistance.

"I ...... I don't know. ”

As soon as I said that, I looked up, and suddenly I found that the corridor seemed to be dark for a moment, and in the darkness so thick that I couldn't reach my fingers, two red dots stared at me in the depths of the darkness, like eyes, and the moment I found it, they flashed by and disappeared.

I trembled and stretched out my finger to the doorway, and Lynn looked at me with a pale face and instantly lost her blood, and immediately knew that I had found something, and quickly turned her head to look - of course she didn't find anything, she couldn't have found it.

Because, that thing only appeared so that I could see it alone, and I had this intuition.
