Doomsday Bunker Upgrade Chapter 83: Thank you for the 100,000 reward for the palpitation leader

In the bedroom, Chen Xin was leaning on the bed and using the CAD drawing software on his laptop to design the door of the shelter.

When the system upgrades items or the shelter, it can be modified according to Chen Xin's ideas, so Chen Xin decided to add some of his own ideas to the door of the shelter.

As the first door of the Refuge to resist the invasion of the outside world, it is also the strongest defense. In Chen Xin's vision, the door of the Refuge is not just a gate.

Before the disaster, when everyone in the survival group discussed how to build a doomsday shelter, everyone had put forward many plans for this issue.

The original plan was put forward by the big guy who made water purifier equipment. He borrowed 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. , Everyone lived in to form a small community.

In this scheme, the gate of the shelter is designed as a protective screen door of the same level as the civil air defense project built by the country. The reinforced concrete structure weighing more than three tons is wrapped with steel plates. And other supporting equipment.

Such a gate structure is standard enough to withstand the impact of nuclear bomb 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 scrapped 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 hilltop to dig a hole in the ground according to the construction plan proposed by Chen Xin, and then fill in the specially customized container house to build a shelter.

　　The refuge built in this way is certainly 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 extremely cold low temperature and severe air pollution, which are much easier to deal with than nuclear radiation.

And the door of the shelter was replaced by the three-proof door that everyone can buy, instead of the previously expected protective screen door.

Originally, Chen Xin didn't think too much about this. The three defense doors he installed were twenty centimeters thick. If the two doors were locked from the inside, it would be very difficult for a tank to take the two doors. The door is torn down.

But now that the system has been upgraded, Chen Xin feels that he can still make his gate stronger and more secure, and improve his defense a little bit.

In Chen Xin's conception, he will add the current two three defense gates to three, and renovate the corridor to enter the refuge.

　　The first door is naturally the outermost door of the refuge. After entering, it should be a sanitation 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 horrible thing as nuclear radiation, since knowing that chemical plants have exploded, Chen Xin knows that the air outside is no less deadly than a nuclear bomb exploded at his door.

　　The sanitation room is absolutely necessary. The toxic and harmful substances that have been infiltrated into the air may not be as deadly as nuclear radiation, but if they are accidentally contaminated, the medical conditions are far worse than those in the pre-doomsday era. , I am afraid that the terrible level is still higher than nuclear radiation.

Not to mention anything else, if you are drenched in acid rain, with today's medical conditions, unless Chen Xin creates a medical cabin that can repair his body tissue, he can only live rather than 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 now the acid rain has a much higher acid-base concentration than before the disaster. If it gets exposed to it, it will really corrode the skin.

　　 And after the washing room, Chen Xin is going to build a preparation room.

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

　　Chen Xin plans 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, and after everything is prepared, you can start from the preparation room without needing to thread the protective equipment into the interior of the shelter.

This will both free up space inside the now somewhat crowded shelter and reduce the possibility of outside harmful substances being brought into the shelter.

Between the cleaning room and the preparation room, Chen Xin also plans to install another partition door to prevent harmful substances from entering the shelter through the air. At the same time, a defense can be installed between the preparation room and the cleaning room. arms.

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

　　 He is no better than all the defense facilities of the official refuge, and the outer door is not as strong as the official refuge. If the door is opened by someone, he always has some self-protection means that can kill the enemy.

The ideal way is of course to make the kind of laser corridor in the "Resident Evil" movie ~IndoMTL.com~ as many people come as one death.

　　 But Chen Xin just thinks about this kind of thing. Actually, I don't mean that I 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 can 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 a bow and arrow to make a bed crossbow 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, the lethality is also nothing to say. The arrows can also be recycled and reused, which is highly energy-efficient and environmentally friendly.

　　 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 a cleaning room. The cleaning room is connected to the preparation room. The middle is connected by a short corridor. Two partition doors are installed. The corridor is equipped with a heavy crossbow. , Or simply the enemy, shoot him a bunch of candied haws.

After entering the preparation room through the two partition doors, it is necessary to pass through a three-guard gate to officially pass through and enter the corridor 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 short-wave antenna and air vents inside the shelter, so as to avoid the danger of the enemy cutting off his own communication and poisoning the interior of the shelter through ventilation pipes.

　　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.
