The prison's library, barber room, kitchen, and dining room are lined up along the central corridor, while on the other side are exhibition rooms, shops, screening rooms, maintenance rooms, warehouses, etc.

Life on the island is certainly not as pleasant as in the cities on the mainland, and these functional places are shared by prison guards and prisoners, so regular cleaning is necessary.

Shen Fei had already preliminarily conceived a prison escape plan in his mind, and he was still refining it according to the actual situation.

Although he can't use his extraordinary abilities and system functions, this is far beyond the physical attributes of ordinary people, and it still provides him with the possibility of escaping from prison.

For example, the 2.5-kilometer strait is difficult for ordinary people to cross, but Shen Fei has a certain confidence in this, and what he must solve is how to prevent being attacked by sharks.

To prevent sharks, Shen Fei's first thought was shark repellent.

The original shark repellent was a concentrate from the body of a deceased shark, but the results were not very promising.

The post-industrial preparation of shark repellent is made by sulfonation of oil-soluble aniline black and oleum sulfuric acid to generate sulfonated products, and the sulfonated products, deep well water, calcium carbonate, and tributyl carbonate are diluted and neutralized by the process, and then the products obtained by filtration, concentration and drying are mixed with copper acetate in a certain proportion and ground into powder.

When the powder comes into contact with seawater, it quickly dissolves and spreads, releasing a black-blue solution with the smell of copper acetate chemicals that sharks repuls.

But Shen Fei, who was in prison, had no conditions to make, so he could only settle for the next best.

Common in life, and can also be obtained in prison, is detergent and copper sulfate, both of which have a certain repellent effect on some sharks, as for how good the effect is, it is immeasurable, it can only be said that it is better than nothing.

Detergent and copper sulfate are available in the maintenance room, and Shen Fei only needs to find an opportunity to secretly bring out some.

But if you blindly believe in the effects of these two things, you will not take your own life seriously.

Another way to avoid being attacked by sharks is not to go into the water, and if you don't go into the water, you need a boat, but it is still possible to find a plank to make an oar on the coast, and it is a bit whimsical to make a boat, and he has to find another way.

And the sea crossing link is the simplest part of Shen Fei's cognition.

Looking at the whole prison escape process, the real difficulty lies in how to sneak out of the prison without knowing it and buy enough time to cross the sea.

He has only spent two nights in prison and has not mastered the regularity of the prison guards' patrols, which he must master within a month.

But it is not possible to pin all hopes on this, in case the prison guards switch patrol hours just in time for him to escape, and the previous preparations will be wasted.

And in order to prevent this from happening, Shen Fei must find a way so that no matter how much the prison guards patrol, they will not be able to find out that he has escaped.

At the same time, if it is decided to dig the vent with a spoon, it is necessary to solve a crucial problem, which is how to disguise the vent after it has been enlarged.

Regarding these two points, among the 36 strategies, there are two ways to deal with them - hiding from the sky and crossing the sea, and the golden cicada is out of its shell.

——

On the afternoon of the third day of the prison escape mission, it is time to release the wind.

In order to maintain his character, Shen Fei behaved like a lone wolf, just like a month before he came in, with a cold face, wandering away from the crowd, scanning everyone with gloomy eyes from time to time, ready to attack at any time.

And the prisoners' response is also very simple, just stay away, as long as they don't cause trouble in front of him, he will not take the initiative to find fault.

It seems that there was no brawl, which made Shen Fei lose interest, and gradually moved away from the crowd, haunting the maintenance room and the waste goods warehouse.

Whether it was a prison guard or a prisoner, they all showed a habitual appearance for his solitary figure, which made Shen Fei's actions a lot easier.

There are a lot of tools such as screwdrivers and wrenches in the maintenance room, but there is a strict registration in and out of the warehouse, and it is not so easy to get by.

But there was an item that was negligently managed, but it caught Shen Fei's attention, paint, this thing......

Prison guards don't usually inspect the cells because they are simply furnished and can be seen with a glance, which means that there is no suitable place to hide things.

So this was not a good time to take the sheep in his hands, at least until the vents were dug up, and he couldn't take too much back to his cell.

So he appeared here at this time for two purposes, one was to step on the spot and see what could be used for jailbreaking, and the other was to get everyone used to the fact that he liked to run around so that he could do things later.

And the warehouse of waste items gave Shen Fei a little surprise.

Here he found a discarded vacuum cleaner, which was a good thing.

Taking advantage of the fact that there was no one left and right, he disassembled the vacuum cleaner, took out a small motor inside, hid the micro switch and two wires on his body, and found an opportunity to bring it back to the cell and hide it in the quilt.

And the reason why Shen Fei acted very boldly in prison had to mention the improvement of his five senses brought about by his 10-point perception.

He can roughly judge the direction, position, weight, stride length, etc., just by listening to the footsteps, even during noisy music hours.

Cameras began to be popularized in the United States around 1982, so there were no such rare things in prisons at this time.

The prison without cameras can only rely on the prison guards to monitor humanitarianly, with Shen Fei's hearing, he can basically know the nearby duty and patrol situation well, and the intelligence of 10 points also provides extremely fast brain computing speed.

This is equivalent to opening a map to hide from monsters, opening perspective hide and seek, if it weren't for the terrain restrictions, Shen Fei could hide with them until the end of the world.

He also took out a bundle of iron wire and some glue from the warehouse, and Shen Fei also hid it on his body, and when he was leaving, he noticed a batch of raincoats stacked in the corner of the warehouse, thoughtfully.

For tonight's music time, Shen Fei chose the accordion.

Joke time, ask, what is the oldest musical instrument in the world?

A, accordion, because it has the most wrinkles on the face.

Well, Shen Fei didn't choose the accordion to play, but just wanted to study its bellows structure, which was a whim after seeing the raincoat in the warehouse in the afternoon.

Experiment to make sure that some of your ideas work, and you won't waste time.

He took the spoon out and fixed it to the tip of the vacuum cleaner's motor with wire.

At the motor wiring, the positive and negative poles are led out with wires, and then through the micro switch, another section of the wire is peeled off to expose the copper wire inside.

In the prison cell, sockets, which were thought to be useless, are of paramount importance.

Put the exposed part of the wire into the positive and negative electrode holes, press the micro switch, the motor will rotate rapidly, and a simple hand electric drill will be ready.

The noise created by other prisoners playing musical instruments was used to mask the noise of the electric drill drilling through the wall.

What Shen Fei didn't know was that when he didn't come, the prisoners could vent their emotions from time to time.

But since he arrived, the prisoners have been unable to release their hearts for fear of being misinterpreted as a brawl, and they have been unable to release their daily energy for fear of misunderstanding the brawl, so musical time has become one of the few means to vent their anger.

The cause planted inadvertently produced the fruit that Shen Fei wanted, and the sufficient noise greatly reduced the probability of the hand drill being discovered.
