At this time, Ye Chu saw A23 walking towards him menacingly, Ye Chu was not afraid at all when he saw this, and stood still and waited for A23 to come over.

After a while, A23 came to Ye Chu's side, and the prisoners in Area A surrounded Ye Chu, and there were only Ye Chu and A23 in the middle.

A23 showed a mouthful of big white teeth, looked at Ye Chu and said, "Are you going to escape from prison?"

Ye Chu nodded, A23 nodded and said, "What are you using to escape from prison?" Ye Chu smiled disdainfully and lightly tapped his head with his hand, and the subtext is: brain!

A23 nodded and said with an unkind gaze, "How sure are you that you can take many of us out?"

Ye Chu said: "It's not all, but you, me and Prosius!"

A23 said with some anger in his heart, "Why not all of us?"

"The more people there are, the bigger the target, this will only make it more difficult for us to carry out our prison break!" Ye Chu said and stretched out five fingers and continued: "Three people, fifty percent sure, if you bring someone with you, the result can only be a failure to escape from prison, and finally be hanged!"

A23 thought for a moment, then looked at him kindly and said, "If there is an internal structure diagram, can't you still take us all out?"

Ye Chu nodded and said, "I'm afraid that's the case! I'm also helpless, but you can go out and destroy this place, so that you can save all the people here." ”

A23 looked at the people in his prison area, their faces all revealed disappointment, they were all the builders of this prison and the first batch of prisoners in this prison, except for A23, who was still young, it was not an exaggeration to describe the others as old, weak, sick and disabled.

A23 said that he was about to lift his clothes, but was stopped by an old prisoner, who said: "Believe me, I will definitely save you when I leave!" I swear in the name of Allah. ”

After Ye Chu heard this, he knew that A23 was a *** teacher.

The old prisoner was muttering something to A23 in the dialect of an unknown country.

A23 glanced at Ye Chu, and also said something to the old man in muttering words, and he didn't know what he said, so the old prisoner let go of A23.

But Ye Chu heard their words from the language, and he heard them in North Africa, and Ye Chu combined their appearance to conclude that the prisoners in Area A were all from the South African country.

After A23 said something to the old man, the prisoners in Area A quickly shrank, and the space became much smaller, so small that they could only accommodate A23 and Ye Chu.

A23 lifted his shirt, revealing his black back, perhaps because his skin was too dark, Ye Chu didn't see anything.

A23 gestured to an elderly man wrapped in a turban on the side, and the old man took off the turban and took out a purple light from the turban and lit it on A23's back.

Suddenly, the place on the back of A23 that was illuminated by the purple light appeared, and Ye Chu knew that this was tattooed with a special liquid, and only with ultraviolet light could the structural diagram be revealed.

Ye Chu was very surprised when he saw it, and took the purple light from the old prisoner's hand and began to check it on A23's back.

Ye Chu has hyperamnesia, but in order to deepen the impression, Ye Chu used his fingers to slide on A23's back according to the direction of the line, and showed a three-dimensional picture of the prison in his brain.

Ye Chu found that the structure of this Crowno Prison was an irregular hexagon, and it was divided into several small hexagons in the large hexagon.

The four wards A, B, C, D, and E are only one of these hexagons, and none of them are connected together, occupying the four inner corners of the hexagon.

The dining hall they are in now is in the middle of the hexagon, each with a passage connecting to the four ABCD wards.

The small black room is located in the middle of Wards C and D, and in the middle of Cell-B is the interrogation room.

......

While Ye Chu was buying time for Prosius and A23, he calculated why he hadn't seen the guards after so long.

After surveillance, Salva saw that more and more people were involved in the beating, and it was about to be uncontrollable, so Salva asked his men to intervene and end the riot.

Soon a multi-flash door opened on the steel wall, and countless guards in black armor rushed out with electric shock batons and shields in their hands, shouting: "Stop fighting!"

As he spoke, he waved the weapons in his hand and knocked all the prisoners involved in the fight to the ground, and for those who were already red-eyed, he was very simple and rude, and directly stunned them with electric shock batons.

Prosius and A23 stopped fighting when they saw it, and they were very cooperative and lay on the ground with their heads in their hands.

And Ye Chu seemed to attack the guards who rushed in with red eyes, Ye Chu hid his strength, and after defeating the two guards, he deliberately exposed his flaws to let the guards stun him.

Ye Chu's purpose in doing this was to have a reason to enter the "little black house" that everyone feared.

Because Ye Chu observed that although this is a steel prison, there are many places that are not steel, such as the interrogation room.

But the interrogation room was guarded, but only "that little dark room" was unguarded.

Although the "small black room" is also a steel structure, the last time Ye Chu entered, he found that there were rivets and gaps where the incandescent lamps were installed in the small black room, indicating that the incandescent lamps and the rest of the walls were not a whole.

Not surprisingly, Ye Chu was once again locked up in a small black room, and when he just opened his eyes, the incandescent light on the wall lit up and began to emit temperature.

Ye Chu quickly got up, squinting his eyes and groping around the edge of the incandescent lamp and the wall.

But the heat emitted by the incandescent lamp was too high, and Ye Chu was burned as soon as he touched it, and subconsciously retracted his hand, but Ye Chu refused to give up, took off his clothes to block the heat and continued to grope with his hands, and sure enough, the emperor lived up to his heart, and Ye Chu touched a bulge.

Ye Chu knew that this was a rivet for fixing an incandescent lamp, Ye Chu tried to buckle the rivet with his hand, but it was so easy to buckle up.

The rivets were tightly embedded in it, and after a while, Ye Chu's fingers were already full of blood.

But Ye Chu still didn't give up, his body was soon soaked with sweat again, and he didn't know how long it took, these incandescent lights went out at once, although it fell into darkness, but Ye Chu knew that the following was to resist the cold.

As the temperature continued to drop, the ultra-high temperature in the small black box quickly dropped, Ye Chu thought of something, there is a term in physics called thermal expansion and cold contraction.

These little rivets are iron, and the walls are also iron, and when exposed to high temperatures, they will expand, and the force of expansion can cause the rivets to burst out of the steel.

But how do you get the temperature to the point where the rivets can burst out? The temperature of these incandescent lamps is high, but only for people.

Ye Chu remembered to focus away again - with a magnifying glass.

Everyone has played a small game of burning ants with a large mirror or burning paper to light a fire in early childhood, and this is focusing.

But how to get your hands on something like a magnifying glass or a convex lens in this heavily guarded Kronor prison is very difficult.

Ye Chu was brought out after surviving the high and low temperatures.

When Ye Chu was taken out of the small black room, it was time for the prisoner to eat.

After Ye Chu was brought out, Prosius walked up to Ye Chu and asked in a low voice, "How is it?"

Ye Chu whispered while eating, "I need something like a magnifying glass or a convex lens that can concentrate light." Ye Chu said and saw the black man on A23.

A23 looked at himself and Prosius with resentment in his eyes and asked, "A23, you didn't get it?"

Prosius didn't speak, but after a moment he said, "Are glasses okay?"

"It can be regarded as having a spotlight effect!" Ye Chu said!

Prosius nodded and said, "Leave it to me, I know where to get glasses." Then he asked Ye Chu again, "What else do you need?"

Ye Chu said: "When we rely on it, there is no way to escape from it, we must first know where we are, so I need paper and pen to make a simple theodolite, determine the location and convey it to the people in the outside world to help us escape from prison!"

After hearing this, Prosius said happily: "The inside should be together, so that the possibility of our escape from prison will increase!"

But Prosius soon fell into contemplation, he certainly knew that he could make a simple theodolite with pen and paper, but the method of use was to find a fixed direction in conjunction with the celestial bodies.

In other words, you have to go outside the prison, but in the years since you were imprisoned in Crowno, there is only one kind of person who can leave, and that is the dead.

After hearing this, Prosius said that he could get pen and paper, but it was impossible to get out of prison.

After saying the difficulty, Ye Chu said that he could get what he needed first, and after Prosius finished speaking, he picked up the small spoon for eating and hid it in his sleeve, walked to the side, and said to Ye Chu: "I hope I heard you!"

When passing an A23, Prosius immediately clutched his abdomen and let out a scream, and when he turned around, he saw Prosius's abdomen rubbing a spoon, and blood continued to flow out.

Prosius was very frightened and stepped back to see the A23 acting very panicked, and shouted desperately as he retreated: "Help, he's going to kill me!"

A23 looked at Prosius with a confused face and kept shaking his hand and said, "No, I'm useless, I didn't hurt him!"

Prosius said something in A23's ear, and A23 glanced at Ye Chu and nodded.

Ye Chu, who was watching from afar, understood what was happening, and although he didn't know what A23 said in Prosius's ear, he already knew that Prosius had already made sense that A23 had cooperated to escape from prison.

But what Ye Chu didn't know was why Prosius would self-harm, and did his self-harm help with getting what he needed?

In a few moments, the door opened from the steel wall, and several guards rushed in, while Prosius fell to the ground, motionless, as if unconscious.

One of the guards examined Prosius' injuries and said, "Send it to the infirmary!" as Prosius was taken away.

After Prosius was taken away for medical treatment, a prisoner from Area A walked up to Ye Chu and said, "Our boss wants to see you!"

After hearing this, Ye Chu glanced at No. A23......
