Each personality has its own independent life with each other.

Zhang Yichi flipped to the third page of the report, which was a floor plan of the crime scene. One living room and one bedroom, their family is very small.

"This is your home?" Zhang Yichi asked.

One glanced at the floor plan and said "um": "The toilet and kitchen are crammed together, and there is only one bedroom." The biggest headache is that from time to time there will be a water and electricity cut, but fortunately, it is quite close to the place of work. Oh, only such a dilapidated house can live in this kind of land for a thousand yuan for a month - not including utility bills. ”

Zhang Yichi listened and looked at the floor plan: "Do you usually sleep with your brother? ”

"Hmm." No. 1 had been calm before, but since he talked about the family situation, his tone began to take on a hint of sourness, "I've been sleeping with my brother all these years. In the past, when I was not or sleeping, he would sneak out and be in danger several times. So when I went to bed, I would tie our hands together with a rope so that I could wake up as soon as he moved. ”

"Then how do you take care of him at work?" Zhang Yichi asked again.

"Normally, at 10:30 I would tie myself and my brother to sleep, and when I woke up at midnight, I would quietly untie the rope and make the blueprints. When to finish and when to go to bed, three or four o'clock in the morning, five or six o'clock in the evening. After finishing the work, I tied the rope again, slept until half past seven, and got up to make breakfast for my brother. Then No. 2 wakes up and takes his younger brother to the billiard hall near the company. The owner of that billiard hall is a very good friend of mine. When he heard about me, he was kind enough to help me take care of my brother. In fact, it can't be said to be care, that is, to lock up my younger brother, watch him not do dangerous things, and give him some food at noon. ”

Zhang Yichi nodded, and wrote in his notebook what time each of their personalities was doing.

"But we can't let Jiabai help, we will give the food money and hardship expenses of the younger brother every month, adding up to five or six hundred. In fact, it's already quite good, if we really spend money to hire a special person to watch my brother, we can't afford the price. No. 1 had a deep voice, and it seemed that it had been a difficult time all these years, "After sending my brother over, No. 2 went to work." Usually leave work at 6 p.m. Number Three will pick up his younger brother home, cook, and help him take a bath. Anyway, it's basically like this every day. ”

"Okay." Zhang Yichi finished writing the last word in the notebook, put the notebook aside, and picked up the report book, "The situation is almost finished, and we will start looking for the murderer now." ”

"How?" Number One hadn't gotten out of his sad mood yet, and was slightly depressed.

Zhang Yichi spread the floor plan between the two: "If you want to prove that you are not a murderer, and if you want not to be erased, you have to analyze and find out the truth with me...... Your brother fell to his death from the balcony next to the kitchen and bathroom, do you think the number three pushed him down? ”

"All the windows in our house have been remodeled and can only be opened by a third. It's hard to get out of that little space. And my brother is very small, and if he wants to jump from there, he has to step on a stool. But when I woke up, there were no stools on the balcony at all. If it wasn't for Number Three who got him down, how could my brother have fallen. Number One tried to suppress his anger.

"But this is a joint crime, if you just push your brother down, do you need to join forces? Number Three, he can do it alone in the time he wakes up. Zhang Yichi felt that No. 1 had a strong sense of substitution, as if he was inciting his emotions, but fortunately, he always kept calm and quickly found the place where the logic didn't make sense, "In addition, if No. 3 wants to kill his younger brother, why would he choose this way that doesn't sound very convenient to operate?" He can use a knife or other ...... that is easier to handle."

No. 1's breath was a little unsteady: "When I woke up, the balcony was in shambles, like there had been a fight. I don't know exactly what happened during that time......"

Zhang Yichi took everything in his eyes, exhaled softly, and kept quiet for a while, leaving a little time for No. 1 to recover.

After a few minutes, One's mood stabilized a lot, and he was still sluggish: "Go ahead." ”

"Do you hate your brother? Do you think he's a burden? Zhang Yichi asked a very sensitive question.

"It would be too false to say that there are no such thoughts at all." No. 1 laughed at himself, "I've been annoyed with him since I was a child, he has been through a lot of troubles, I work every day and I'm exhausted and I feed him, and he doesn't eat." If it weren't for him, I would have lived quite well alone. I know you're suspicious of me and looking for my motives for killing my brother. But I wouldn't have killed my brother because of this, otherwise I wouldn't have been able to feed him until now. ”

“…… You said that you do have these thoughts, but it still surprised me, and I have always been quite sincere, so I don't need to be so nervous, I suspect that it is normal. Zhang Yichi appeased No. 1.

Zhang Yichi will not relax his vigilance against No. 1 because of such a statement, after all, no one can be sure that what No. 1 said is true or false. And One does have an incentive to do such a thing, even if it's far-fetched for now.

But it is true that as he said, if he wanted to kill, he would have killed it a long time ago, so why did he have to wait until this time? And if it was really the one who did it, then how did he manage to make his brother fall to his death during the awakening of the three?

Zhang Yichi stood up, put his hands in his pockets and walked around the small secret room boringly: "Do you want to get up and take a walk?" Sitting for so long. ”

No. 1 didn't listen to Zhang Yichi's words, and when Zhang Yichi walked to the back of No. 1, No. 1 stretched out his hand holding the cigarette case, turned his head and asked, "Do you smoke?" ”

"Huh?" Zhang Yichi's eyes lit up, pulled out a cigarette, and thanked him, "Is there still smoke here?" ”

"Of the three of us, I was the only one who smoked, and I always had it in my pocket." Number One explained, and took a cigarette in his mouth and smoked.

The secret room was quiet for a while, and Zhang Yichi stood in front of the locked door, holding a cigarette in one hand and a cigarette in the other.

What's behind this door? Where does it lead?

"Well......" he put on his cigarette and turned to the first one, "look to see if there is a key or something, there is no such door for nothing." ”

With that, he began to search carefully in the secret room, but Number One was not very interested in this, and still did not get up, but leaned over to look for it perfunctorily.

The secret room is so big, and there is no place to hide, so it didn't take long for Zhang Yichi to find it.

"Huh......" Zhang Yichi looked at the door, and asked No. 1, "Where do you guess where this leads?" ”

"I don't know." Number one return.

"Huh." Zhang Yichi threw the cigarette butt on the ground and stepped on it, stretched out his hand and pulled the door hard, but the door did not move, "This door is very strong, it is impossible to break it strongly...... Since we can't open it, let's wait for it to open on its own. ”
