The scene of the crime is this four-person dormitory where Xia Qi has left traces for three years. The informant was Cao Jinhai, who got up in the middle of the night to go to the toilet, and when he returned, he found that Yang Shucheng had been killed.

In the interrogation room of the police station, Cao Jinhai sat opposite Xia Qi and a middle-aged policeman in a broken down, and narrated in a hoarse voice:

"Changye doesn't know what stimulation he has been exposed to these days, he is nervous all day long, and he doesn't go out to eat with us, so he stays in the dormitory alone, and doesn't go to any classes."

"Did he say anything to you? For example, you said stimulated. The middle-aged policeman asked at this time.

"Yes, he said he's been dreaming all the time these days, and he's always dreaming the same thing."

"Dreams?"

"Well, it's a nightmare, that's what he said, and he talked to me about it for two days."

"What kind of nightmare is it?"

"I didn't listen to the specifics, but I just heard him say that someone wanted to kill him."

Cao Jinhai repeated what he said to Yang Shucheng and them at dinner that night.

"Is it someone in a dream who wants to kill him, or is someone in reality trying to kill him?"

"It should be a dream, how could anyone kill him in reality? Besides, even if someone really wants to kill him, they won't let him know! ”

Cao Jinhai's emotions suddenly became very excited, obviously recalling the tragic scene he saw at that time.

"The sea, you drink saliva first."

Xia Qi handed Cao Jinhai a glass of warm water at this time, and after he finished drinking, he signaled to the middle-aged policeman next to him to continue to ask.

The middle-aged policeman nodded, and then spoke again:

"One thing you need to understand is that we have to work out every detail. Because this case is very bad and there are many suspicions, I hope you can understand us and cooperate with us. ”

Cao Jinhai put down the water glass tremblingly, and looked up at the middle-aged policeman with a dignified face:

"They're all good buddies of mine, and I'll cooperate."

"Well, thank you for your cooperation." The middle-aged policeman symbolically said a word, and then returned to the topic:

"What did you do before the case?"

"Do you mean night?"

"Hmm."

"In the evening, we went out for dinner first, but Changye was still so nervous, so he didn't go out with the two of us. We had a little bit of wine with Shucheng, a bottle of beer each, and I swear none of us got drunk.

Shucheng wanted to send something to his object, so I went back first. When I got back to the dormitory, I found that Masano was sleeping, and I didn't wake him up, so I climbed to the top bunk alone and chatted with my friend on my mobile phone for a while.

At about nine o'clock in the evening, Shucheng also returned to the dormitory, and Changye didn't wake up at that time, and the two of us complained about him at the time, thinking that we must take him to see the above tomorrow, saying that if he stays like this, everyone will be wasted.

We woke up early in the morning, so we didn't talk too long and went to bed. ”

When Cao Jinhai said this, the middle-aged man suddenly interrupted him and asked:

"Did Yang Shucheng sleep at this time?"

"I'm not sure, but I think he slept."

The middle-aged policeman nodded after hearing this, quickly wrote two strokes in the notebook, and motioned for Cao Jinhai to continue.

"I woke up with urine, and I put up with it for a while because I was too lazy to go down, but finally got out of bed."

"Do you know what time it is?"

"At 10:20, I remember it very clearly, because I also looked at the time."

"Did you find anything wrong? For example, Yang Shucheng or Li Changye. ”

"There's nothing wrong with it, because I hear Shucheng snoring, and I'm not sure if he is awake or not. But when I came back from the bathroom, I found ...... I found ......"

Speaking of this, Cao Jinhai's voice knotted again, and it took a long time to say it with difficulty:

"I found that Changye was stabbing Shucheng with a knife one after another!"

"It's almost 12 o'clock, and it should be dark in the dormitory, why do you see so clearly?"

The middle-aged policeman still asked very carefully, and he didn't want to let go of any details.

"At that time, there were no curtains in the dormitory, I saw it through the moonlight, but I didn't see it clearly at the time, I only saw two figures vaguely, and then I pressed the light switch on the wall to see it clearly."

"Aren't the lights out in the dormitory?"

"We have 24-hour power supply in our dormitory."

This time it was Xia Qi who spoke, and as a student of the Talent Academy, he was well aware of this. And their dormitory building also has a high-ranking nickname - the city that never sleeps.

Hearing Xia Qi's testimony, Cao Jinhai also nodded and said affirmatively:

"We don't have power in that dormitory building."

Speaking of which, he added:

"You all know what happened after that, I was terrified, and I didn't realize to call the police until I fled downstairs."

"Well, thank you for your hard work, you can go back now, but please make sure that your mobile phone can communicate normally these days, and it is also convenient for us to contact you. Of course, if you think of anything during this period, you can also call us in time, my mobile phone number has been given to you before. ”

The middle-aged policeman stood up from his chair at this time, and then waved his hand at the monitor overhead, and a policeman came in and took Cao Jinhai out after a while.

Before going out, Cao Jinhai also turned his head to look at Xia Qi, signaling him to go out first and look for him later.

The middle-aged policeman also sorted out the transcript at this time, and said to Xia Qi with a somewhat ugly smile:

"There seems to be nothing to say about this case, there is all the human and material evidence, it is Li Changye who killed him. But then we're going to do a psychiatric diagnosis on Lee Changye to see if he has mental problems, or sleepwalking or something. ”

Although it seems that this matter is already very clear, Li Changye has had mental problems recently, so he has been suspicious for a while and thought that someone wanted to kill him, and then killed Yang Shucheng by mistake.

Everything seems reasonable, but when you think about it, there is still a doubt, that is, how could Li Changye have mental problems?

Li Changye is a person he doesn't know better, and he can't be described as optimistic in his usual life, but a typical kind of heartlessness, they have never seen him worry about anything since they knew him for so long.

So it's hard for him to believe that someone like this could be mentally ill and kill a roommate with whom he had a good relationship.

"I hope you treat him well, I'll come back tomorrow morning, and I'll ask him face to face if I have something to say."

If it had been before, Xia Qi wouldn't have dared to think that he had just spoken to the police, but now, with his work card of unlimited bulls, he has done it.

But there was no joy at all.

When I came out of the police station, the time had come to more than 1 o'clock in the morning, and there was not a single car on the empty road, and Cao Jinhai was squatting on the side of the road, with his head lowered as if he had lost his soul.

Xia Qi asked himself, if it weren't for his recent experience, let him witness this bloody tragedy with his own eyes, he would also be unbearable.

"Hey."

sighed sadly, and Xia Qi also walked towards Cao Jinhai a little awkwardly.
