Mo Chen couldn't remember exactly how many windows there were on the fourth floor when he looked outside the building, and if there were not ten, there would be eight or nine windows.

Mo Chen first assumed that the window was eight, if one window corresponded, a cell here.

Except for the four cells on one wall, where are the remaining four windows?

Mo Chen stared at the wall he came in, and outside the wall was the boiler room where he met Xiao Hao.

At that time, Mo Chen's attention was all on Xiao Hao's body, and then he was in a hurry to find Professor Wen, so he didn't check what was on the back of the boiler.

Perhaps, in the dark corner behind the boiler, there are a few cells, or maybe an office.

Blindly trying to think about the answer to something that can't be verified at the moment is just asking for trouble.

The hypothetical layout of the fourth floor in Mo Chen's mind was each cell, and the wall opposite the door should be the window he saw when he came.

Thinking of this, Mo Chen turned around and walked into the room where Dai Min had been imprisoned, and the wall facing the door was a single iron bed against the wall.

Mo Chen walked to the wall, stretched out his hand and knocked twice on the wall, and the wall reverberated empty.

Huh?

Mo Chen was stunned for a moment, then changed his position and knocked twice, and there were two empty echoes.

Mo Chen was a little excited, because the echo he got from these two beatings was different from the echo of any wall in the corridor.

Most of the walls of the corridor are the load-bearing walls of the building, and to put it bluntly, the inside is solid, and if you gently pat it with your hand, you will hear the crisp sound of crackling.

And Mo Chen just faced this wall, and when he knocked on it, he heard the echo, and found that this wall was not consistent.

In the middle of the wall, the place that reverberates in the air is actually a vertical rectangle.

In Mo Chen's mind, a picture immediately appeared, the master craftsman, building a wall on the windowsill and blocking the window entirely.

"Found the mechanism?" Li Fang didn't know when he walked in, he saw Mo Chen concentrating on studying the wall in front of him, so he asked.

Mo Chen shook his head, "No, but...... It's a bit of hope! ”

Mo Chen knocked on the wall in front of him, suspected of the location of the window, and said to Li Fang, "Listen here, the echo is empty, there must be a window or something like that behind here." ”

"Windows?" Li Fang reached out and knocked on the wall twice in confusion, and immediately put his ear on the wall to listen.

Li Fang said confusedly, "Even if we can smash this wall open, you said before, I'm on the fourth floor now." Do you want to ...... Climb downstairs? ”

"Dead horses should be live horse doctors!" Mo Chen shrugged his shoulders helplessly.

This is the prison cell, where will there be a suitable tool, and after looking around, the old and loose iron bed headboard attracted Mo Chen's attention.

Mo Chen and Li Fang worked together to turn over the single bed with iron control, Li Fang stepped on one side of the bed board, Mo Chen held the iron pipe of the bracket at the head of the bed, and pulled it hard. The interface of the iron pipe welding, clicked, and went down in response.

After a while, Mo Chen and Li Fang removed all the four iron pipes at the head and foot of the bed, thanks to this hospital, no matter what facilities are so dilapidated.

A few people outside occasionally came to see them, and when they heard that Mo Chen wanted to violently demolish the wall, they all showed expressions of hearing strange news, perhaps in their opinion, Mo Chen was too whimsical.

No matter what others thought, Mo Chen was still firm in his thoughts, rather than wasting time with a wall with no clues, it was better to find another way.

When, dang, dang, it was the sound of metal hitting the wall, Mo Chen and Li Fang stood side by side, gathering their strength in one place.

It is estimated that it will take almost an hour, and Mo Chen and the others only smashed the empty wall into a recessed nest.

Mo Chen gasped, straightened his waist, and said to Li Fang, "Brother Li, rest for a while!" ”

"Hmm." Li Fang threw the iron pipe to the ground, casually pulled over the dismantled bed board and spread it on the ground, beckoned to Mo Chen, and motioned for him to sit beside him.

As soon as Mo Chen sat down, Li Fang touched his body, and took out two cigarettes out of nowhere, handed one to Mo Chen, and lit one himself.

Mo Chen took a sharp breath and exhaled a big smoke ring, which comes from the unscientific saying of smokers, when the body is tired, smoking a cigarette can instantly relieve the feeling of fatigue, commonly known as "relieving fatigue".

"Eh, Brother Li. I've found that no matter what time it is, you can always pull this 'baby' out of you. Mo Chen said with a smile.

Li Fang smiled, took two puffs of cigarette, and said, "I don't have any hobbies, just this one, but I don't have to pay attention to this thing anywhere, and I have to pull it in my pocket." ”

The two met and smiled, and Li Fang suddenly asked in a low voice, "Xiao Mo, what is going on with you today?" Mo Chen was stunned, Li Fang pointed to the door and said, "Xiao Lei." Don't tell me, it's because Xiao Lei is disobedient that you want to beat him. ”

Mo Chen sighed, "Maybe I'm thinking too much!" I think Wang Lei's eyes when he just woke up today looked weird, at least in my opinion, it was not at all the attitude that a delirious patient should have. ”

"You mean...... Wang Lei, he pretended to be crazy and stupid? Li Fang asked.

Mo Chen nodded, "Moreover, as soon as Dai Min came in, Wang Lei's reaction at that time was to immediately rush over and seek protection." Which patient, in your opinion, would have such a clear mind? Dai Min Ke never took care of him. ”

Li Fang nodded, he agreed with Mo Chen's doubts, but Li Fang still asked, "There is nothing wrong with this, it's just that ...... Why did he do it? Is it just for the sake of being taken care of by everyone? Still is...... More insidious. ”

Li Fang's so-called insidiousness, Mo Chen also thought about it, for example, when everyone was in the theme, because Wang Lei had a brain disease, normally speaking, once he needed to have something to do, he would not consider letting him come forward.

Mo Chen pondered for a moment and shook his head, "Probably not!" If he pretends to be crazy and stupid, it is very likely that everyone will think that he is a burden. People's hearts are unpredictable, and he doesn't know if he will be excluded by us because of this, or even backfired, using him as a guidestone. ”

"That's right." Li Fang snuffed out the cigarette butt and said, "Do you want me to find a time to ask him?" ”

"No need!" Mo Chen said, "After what I did just now, I'm afraid he won't be able to say anything now." ”

Suddenly there was a sound of Suo Suo at the door, as if the sound of deliberately controlling the soles of his shoes rubbing against the ground, Mo Chen glanced at it and shouted to the door, "Since you are here, come in and take a hand!" ”

Before the words fell, a figure flashed in, and the person who came was actually the attendant of the blue-haired man.

The attendant sneered, scratched the back of his head, and said flatteringly, "Two elder brothers, is there a place where the younger brother can help?" ”

Mo Chen couldn't help but sigh secretly, people are realistic, just like the little follower in front of him. He must have been in front of the door of the subject, saw Mo Chen's methods, and knew the gap between himself and Mo Chen. Moreover, now that they are trapped here, and Xu Bin is not there, not to mention, even if Xu Bin is present, he may not care whether he lives or dies.

At that time, when Mo Chen attacked the blue-haired man, Xu Bin did not make the first move, which is the best proof.
