According to the autopsy report of the medical examiner, Li Mingyu died of asphyxiation and had no external injuries. No anesthetics or sleeping pills were detected in the stomach.

As soon as he returned to the police station, Shui Bingyu came to the morgue and began the second autopsy of Li Mingyu's body.

Time passed bit by bit, and many beads of sweat had oozed from Shui Bingyu's forehead.

Meng Xingchen was a little distressed on the side to help Shui Bingyu wipe the sweat on his forehead, he didn't dare to say anything, he knew that what Shui Bingyu needed at this time was a quiet environment.

After more than three hours of uninterrupted work, Shui Bingyu finally said excitedly: "Team Meng, I found it." ”

"What's new?" Meng Xingchen was also excited.

"Have you seen the movie Agent Bean 2?" asked Shui Bingyu as she took off her mask, took off her gloves, wiped the sweat on her head with her hands, and sat down on a chair next to her with some tiredness.

"Nope. Meng Xingchen shook his head.

"I thought those episodes would only happen in the movies, where Bean used potions to control the security guards. Unexpectedly, I actually found this neural reagent in Li Mingyu's brain!" Shui Bingyu said.

"What? Then you mean, Li Mingyu was really controlled by someone! Could it be that he is really a live-action version of a doll!" Meng Xingchen asked in surprise.

"That's right, in a sense, he is a live-action version of a doll, his behavior and thoughts are controlled by people, he is a puppet!" Shui Bingyu nodded.

"Then the doll's house he goes to every Friday, is it really a place to buy and sell these live-action dolls?" Meng Xingchen was surprised.

"Quite possibly. He should have been injected with that kind of nerve reagent every Friday, and I found a very small needle behind his ear, and it is estimated that the nerve reagent was injected from there! The effect of this reagent should only last for a week, so he must go to the injection every Friday, otherwise, life is better than death!" Shui Bingyu said.

"How's the investigation going at the Doll's House?" Shui Bingyu then asked.

"When you just did the autopsy, the colleague in charge of the investigation had already reported to me, the doll's house mentioned by Xia Ling is usually an ordinary bar, and there is no problem on the surface. Oddly enough, the bar closed last week and is now empty. According to the owner of the bar near his house, this doll's house usually has no business, but every Friday, there are many owners who drive luxury cars, both men and women. In addition, you must have a membership card to enter. Meng Xingchen said.

"It seems that we are one step too late!" Shui Bingyu was a little annoyed.

"Thankfully, though, we found a website on the Internet about the Doll's House, and they haven't had time to clean it up yet. This website is a place for people with mental illness, and there are many photos of handsome men and women pasted on it, saying that they are all psychotherapists here. Now it seems that they should all be real dolls like Li Mingyu, whose minds have been controlled, for people to buy and sell. We found a photo of Li Mingyu on the website, and we also found that Ren Xuezhen turned out to be their member, and under the page introducing Li Mingyu, we found a record of his previous conversation with Ren Xuezhen. Meng Xingchen said.

"Really! That's great! This is a useful clue! This proves that Ren Xuezhen and Li Mingyu knew each other before! She didn't tell us the truth that day! It seems that we have to talk to that Ren Xuezhen again. By the way, there is also what Ren Xuezhen mentioned, the financial director who introduced Zhang Manzhen to the painting school, and we will also go to talk to him. Shui Bingyu said.

So, Shui Bingyu and Meng Xingchen went to Ren Xuezhen first to ask questions.

"Miss Ren, as far as we know, you have ever suffered from depression?" Shui Bingyu asked straight to the point.

"So what? That was a few years ago. Being mentioned about her depression, Ren Xuezhen was a little unhappy.

"Did you know Li Mingyu before Zhang Manzhen married Li Mingyu?" Meng Xingchen asked.

"I don't know. Ren Xuezhen replied without thinking.

"Miss Ren, are you a member of the Doll's House?" asked Shui Bingyu.

"yes, so what? We're all people who suffer from depression. Ren Xuezhen replied coldly.

"Li Mingyu is the psychotherapist of this family, and we found the previous chat history between you and him on his personal page. Miss Ren, how do you explain this?" Shui Bingyu also asked coldly.

Ren Xuezhen was silent for a moment, this question caught her off guard.

"At that time...... I had spoken to a few psychotherapists on that website, but I never ......" Ren Xuezhen's face became ugly.

"You talked a lot with Li Mingyu at that time, and said that you wanted to contact him individually. You also said that after talking to him, you were in a much better mood. He also replied to you, "You are a lovely and nice girl." He wants to meet you and talk to you in detail. Do you want to see how you answered him at that time?" Meng Xingchen asked.

Meng Xingchen was holding the materials printed out from the computer in his hand, and he believed that Ren Xuezhen had long since remembered what she had written at that time. These are computer records from two years ago, and they were also found by the police through technical means, and it is probably impossible for her to search for them herself.

Ren Xuezhen stared intently at the pile of papers in Meng Xingchen's hand, her eyes glazed.

"I don't remember. She whispered.

Li Mingyu said, Xuezhen, after contact, you are a cute and gentle girl with unique personal charm, I believe that you will not only get better soon, but also quickly capture the hearts of men. I've been taken captive by you. Miss Ren, you not only knew the deceased, but also had some degree of contact with the deceased. Excuse me, what is your relationship with him?" Meng Xingchen continued to ask.

Ren Xuezhen's face flushed, she sat there blankly, her hands twisted together, and after a long while, she said, "Yes, I know him, but how can I take the words on the Internet? What about what we said?"

"The conversation between you and Li Mingyu shows that you have known him before, you have met him more than once, you know his situation very well, you still have a good impression of him, and Li Mingyu seems to have a good impression of you. Miss Ren, what is your relationship with Li Mingyu?" Shui Bingyu asked sharply.

Ren Xuezhen lowered her head and pondered for a moment.

"Well, I'll admit, I knew him before, and I knew him well, but that was two years ago, so what?" she said coldly.

"Originally, it wasn't good, but Li Mingyu is dead now, and you concealed your relationship with him, so it has a lot to do with it. Miss Ren, now please tell me, how familiar are you with Li Mingyu?" Shui Bingyu asked with a serious face.

"Comrade officer, I don't have anything to do with him, really. He said that he was a psychotherapist himself, and I happened to be in a bad mood during that time, and he spoke with a lot of humor and was very comfortable chatting with him. So, we made an appointment to meet a few times in a café alone, that is, to talk together, I talked about my troubles, and he comforted me and enlightened me. That's all. I saw that he was a little financially strapped at the time, so I gave him some money, and then we became friends, yes, I knew him well for a while, but so what?" Ren Xuezhen said.

"After Li Mingyu went to work at that painting school, did you have any contact with each other?" Meng Xingchen asked.

"Nope. We haven't been in touch since he left the doll's house, and I don't know he went to the painting school to become a teacher. Ren Xuezhen said expressionlessly.

"According to our research, he likes to deal with rich women. Meng Xingchen said.

"Who else he's associating, then I don't know. Ren Xuezhen replied coldly.

"Did you introduce Li Mingyu to Zhang Manzhen?" asked Shui Bingyu.

"No! Of course not! Didn't I tell you last time! Was it the painting school that the sycophant treasurer introduced my mother to! But what I didn't expect was that he would be involved with my mother, which I definitely didn't expect, I didn't expect him to be a shameless bastard!" Ren Xuezhen flatly denied.

"Does your mother know about the matter between you and Li Mingyu?" asked Shui Bingyu.

"Of course she doesn't know! Besides, I have nothing to do with Li Mingyu in the first place! I have already said that we are just ordinary friends, we have met a few times and chatted. Ren Xuezhen said anxiously.

"Alright then, Miss Ren, now please tell me where you were on the night of the crime, what did you do, and does anyone have anyone to prove it?" Meng Xingchen asked.

"What, do you suspect that I killed Li Mingyu?" Ren Xuezhen shouted emotionally.

"Miss Ren, please calm down. We didn't say you killed Li Mingyu. We are just looking for you to understand the situation, please cooperate with our work. Shui Bingyu soothed her.

"I was at my own house, watched TV for a while, took sleeping pills, and went to bed early. Ren Xuezhen calmed down and replied.

"Miss Ren, I heard that you have joined the Comfort Club?" Shui Bingyu suddenly asked.

"Yes, I have depression, and after joining the Comfort Club, there are many patients who suffer from depression like me, and we talk to each other and encourage each other, and my condition has improved. What's the matter, is there a problem for me to join a medical institution?" Ren Xuezhen asked coldly.

"There was no problem, but if you join the Comfort Club, there will be a big problem!" Shui Bingyu said coldly.

"What's the problem? I joined a medical institution, and I didn't break the law?" Ren Xuezhen replied coldly.

"Then do you know Liu Mengbai, do you know the water of forgetting worries?" Shui Bingyu continued to ask.

"How do you know this?" Ren Xuezhen asked with wide eyes in surprise.

"You don't have to worry about how I know?" Miss Ren, please answer my question first! Do you know Liu Mengbai and Forget Worry Shui?" Shui Bingyu asked sharply.
