Chapter 84: Thank you for your 100,000 reward

In the bedroom, Chen Xin is leaning on the bed and using the CAD drawing

software on the laptop to design the door of the refuge.

When upgrading items or refuges in the system, they can be modified according

to Chen Xin's ideas, so Chen Xin decided to add a bit of his own ideas to the

door of the refuge.

As the refuge's first door to resist outside invasion, it is also the

strongest defense. The door of the refuge is more than just a door in Chen

Xin's vision.

Before the disaster, when everyone in the survival group discussed how to

build a doomsday refuge, everyone put forward many plans for this issue.

The original plan was proposed by the big water purifier equipment. He

borrowed from the federal plan to rebuild a shelter with an abandoned missile

silo, and proposed to buy an abandoned air-raid shelter, and then transform it

into a small shelter. Together, everyone Live in and form a small community.

In this plan, the door of the refuge is designed to be a protective screen

door with the same level as the civil air defense project built by the

country. It is a three-ton reinforced concrete structure wrapped with steel

plates, plus supporting equipment such as poison filtering and air

purification. .

Such a gate structure is sufficient to withstand nuclear shock waves,

biological and chemical weapons and poisonous gas in wartime, giving people an

incomparable sense of security.

It’s just that this plan was abandoned when it was first proposed.

Without him, Yan Country does not sell abandoned air defense facilities,

especially at this critical moment when the end is approaching.

So afterwards, everyone could only find a hole in the hilltop according to the

construction plan proposed by Chen Xin, and then fill in the specially

customized container house to build a refuge.

Of course, the refuge built in this way is not as strong and reliable as the

abandoned civil air defense project, but considering that everyone is not

facing the horror of nuclear war, this kind of refuge is sufficient.

After all, what everyone has to face is the extreme cold temperature and

serious air pollution, which are much easier to deal with than nuclear

radiation.

And the door of the refuge has been replaced with a three-proof door that

everyone can buy, instead of the previously expected protective screen door.

Originally, Chen Xin didn't have much thoughts about this. The three-defense

door he installed was 20 centimeters thick no matter how thick. If the two

doors were locked from the inside, it would be difficult to remove the two

doors for a tank from outside. .

But now that the system has been upgraded, Chen Xin feels that he can still

make his door stronger and more reliable, and improve his defense a little

bit.

In Chen Xin's idea, he will add the current two three-defense doors to three,

and will transform the corridors that enter the refuge.

The first door is naturally the outermost door of the refuge. After entering,

it should be a sanitizing room that can be cleaned and disinfected to clean

and disinfect people and vehicles and equipment entering the refuge from the

outside.

Although there is no such thing as nuclear radiation in the outside world,

since knowing that the chemical plant has exploded, Chen Xin knows that the

air outside is no less deadly than a nuclear bomb exploded at his door.

The sterilization room is absolutely necessary. Those toxic and harmful

substances that have now filled the air may not be as deadly as nuclear

radiation, but if they are accidentally contaminated, the medical conditions

are far worse than the pre-doomsday era. I am afraid it is still above nuclear

radiation.

Apart from anything else, if you are exposed to acid rain, with current

medical conditions, unless Chen Xin can get a medical cabin that can repair

his body tissues, he will only die.

The acid rain now is different from before the disaster. Before the disaster,

the body was red and itchy at most, causing allergies or lung diseases and

requiring medical attention.

But the current acid rain acid-base concentration is much higher than before

the disaster, if it gets exposed to it, it will really corrode the skin.

After the washing room, Chen Xin was going to build a preparation room.

The so-called preparation room is a place used to prepare travel equipment.

Chen Xin intends to put all the protective equipment that may be used when

going out here, and move the garage up.

In this way, you can prepare here. After everything is ready, you can set off

from the preparation room without the need to pass protective equipment into

the shelter.

This can not only make room for the currently crowded shelters, but also

reduce the possibility of external harmful substances being brought into the

shelters.

Between the cleaning room and the cleaning room, Chen Xin also plans to

install another partition door to block harmful substances from entering the

refuge through the air. At the same time, a defensive weapon can be installed

between the cleaning room and the cleaning room.

Although Chen Xin does not intend to harm people, he still needs to have

precautions.

He is no better than the official refuge with all the various defensive

facilities, and the outer door is not as strong as the official refuge. If the

door is opened by someone, he always has some means of self-protection that

can kill the enemy.

The most ideal way is of course to make a laser corridor like that in the

"Resident Evil" movie ~ www.mtlnovel.com~ so many people come to death.

But Chen Xin just thinks about this kind of thing. Actually, it doesn't mean

that you can't get it, but it's not cost-effective.

So Chen Xin's plan was to get a heavy machine gun in the direction of the

refuge gate. When an unidentified person or enemy comes in, he will shoot

directly, which is convenient and quick.

But now that he doesn't have a heavy machine gun on hand, Chen Xin plans to

use bows and arrows to make bed crossbows instead.

In a sense, using a bed crossbow is even more powerful than a heavy machine

gun, and the effect is better.

Even if it is transformed into a continuous crossbow, its lethality is also

nothing.

Thinking about it this way, the design drawings in Chen Xin's hands are almost

drawn.

The first three-defense door is used as the gate. After entering, there is the

washing room. The washing room is connected to the preparation room. The

middle is connected by a short corridor. Two partition doors are installed.

The corridor is installed with heavy crossbows. If someone is unidentified, or

simply If it is the enemy, shoot him a bunch of candied haws.

After entering the maintenance room through the two partition doors, one has

to pass through a three-defense door to formally pass and enter the tunnel

connecting the refuge.

At the bottom of the tunnel is the last three-proof door.

With this kind of protection, Chen Xin feels that the safety of his refuge can

be improved a lot.

In addition to protection, Chen Xin also intends to adjust the shortwave

antenna and vents inside the refuge, so as to avoid the danger of the enemy

cutting off his own communication and poisoning the inside of the refuge

through the ventilation duct.

Would you like to adjust the structure of the corridor? Make a floor concealed

door and add another defense?

Chen Xin thought about it carefully, but finally gave up the idea. It was not

impossible, but it was unnecessary.
