Doomsday Bunker Upgrade

In the preparation room, put on the protective clothing and buckle the protective mask on his face. Chen Xin organized the equipment he was going to bring.

Originally, Chen Xin planned to let Qin Lan bring the oxygen generator to Mo Qingyan when Qin Lan came to exchange supplies with him, but out of concern for Mo Qingyan, Chen Xin decided to send it to her himself.

The entire oxygen concentrator has been tucked into the SUV's folded back seat, and strapped to make sure it doesn't roll because it's round.

After all, this thing is made of glass, and it will break if it is bumped.

The equipment that Chen Xin brought was still the flashlight and folding trekking poles that he used last time out, but this time the pistol he was carrying was replaced by the pistol he made from Qin Lan.

Originally, Chen Xin thought that he was going to the city and did not intend to bring a gun, but after hesitating for a while, he still put the gun on his body, which is responsible for his own safety.

In addition to these things, Chen Xin also brought a bottle of oxygen.

This is the bottled oxygen he had reserved before. The quantity is not large, and it will be gone when he runs out. However, considering that the oxygen content outside is now low, there may be a danger of hypoxia, so he still packs a bottle on him to avoid any emergency. When faced with insufficient oxygen, it is not impossible to think about it.

After finishing the equipment, Chen Xin opened the door of the upgraded shelter and drove the car out.

After closing all the doors, Chen Xin set off on his way to deliver the oxygen generator to Mo Qingyan.

In the rear-view mirror, the door of the refuge is much more presentable than before. It is no longer a digging a hole and burying the door, but a solid door with cement reinforced around it.

In fact, it uses reinforced concrete, not just cement. Although it looks a lot more conspicuous, it is not without benefits.

Sturdiness is of course the most important, in addition to facilitating drainage.

While the main precipitation has turned to snow as the temperature gets cooler, solid concrete floors are always easier to drain and maintain than regular mud floors.

Driving into the city, Chen Xin had to turn on the lights this time, instead of turning off the lights as he did when he came out.

Because the road has become a bit damaged compared to when Chen Xin came out, and with the rain in the past few months and the occasional meteorite fall, the road has a lot more than when he entered the city last time. sundries.

This made Chen Xin's progress much slower. The car was equipped with an oxygen generator made of glass. The bumps were too severe and it was easy to be damaged. In order to protect the oxygen generator, Chen Xin could only slowly choose a relatively flat road. Walk.

When Chen Xin entered the urban area before, most of the buildings in the urban area were only burnt out of shape, but the overall structure was still there.

But when he entered the city this time, Chen Xin clearly saw that some houses had collapsed.

It was a collapse caused by a meteorite impact. As time goes by, the dust and meteorite debris floating in the sky will gradually fall. The larger the volume, the faster the fall, and now it is the larger pieces of debris that fall.

In a sense, this is also a good thing. The debris keeps falling, and the dust cloud in the sky will not be so thick. After one to two years, the earth will gradually return to sunlight.

For today's human beings, it takes one or two years to recover from no light to a low-light environment, which can greatly improve the living conditions of human beings.

However, it will take a long time to restore normal light, and the years when this dust covers the sky will continue for at least decades, at least two generations.

As for restoring the ecology of the earth to its original state, it will take even longer, and it may take hundreds of years for the ecology of the earth to recover.

For the earth, this may be just a short moment. It is an insignificant moment in the billions of years of the earth. Although this moment has caused great damage to the earth's ecology, it is still insignificant for the entire earth. .

But for human beings, this is a doomsday catastrophe that lasts for generations and affects the survival and development of the entire civilization. It has to be said that human beings claim to be the masters of the earth, but in fact, compared with the entire earth, human beings are like this. Small and fragile.

—————————————————————

Arriving at the door of Mo Qingyan's house, Chen Xin called her on the radio as before.

Compared with the last time when Chen Xin came, Mo Qingyan's home has obviously undergone some reinforcement and renovation. There is an extra circle of barbed wire on the wall, and the iron gate can also be seen to have been reinforced. Even the front of the previous store facing the street was originally The doors and windows of the house were also nailed, and the iron gates in and out of the backyard were even put on simple barricades made of triangular iron and wood.

Although it is a bit conspicuous, it can also be regarded as a security guarantee. At least it is not so simple for someone to do something to Mo Qingyan's family.

After receiving Chen Xin's call, Mo Qingyan and Mo Qingxin opened the iron gate together, and after removing the barricade, they signaled Chen Xin to drive in the car.

After Chen Xin drove the car in, the Mo sisters quickly moved the barricade back to its original position and closed the door again.

He drove the car into the elevator as before, and went down to the shelter with the Mo sisters. Chen Xin got out of the car and took off the mask on his face.

"Ingredients, your protective clothing is good! Where did you buy it? Why didn't I see you wearing it last time?" Mo Qingyan looked at the protective clothing on Chen Xin and couldn't help showing her envy.

Although she also has protective equipment, it is obviously not as good as the very professional protective clothing on Chen Xin's body.

And what she has is a protective mask, a tactical poncho, and cut-resistant gloves, which is far from Chen Xin's protective clothing from head to toe.

Hearing Mo Qingyan asked about the protective clothing on her body, Chen Xin lifted the hat on her head and replied, "I changed it myself, if you are envious of Longniang, you can give me the materials and I will help you. Change one too."

"Oh oh oh! Did you actually make the ingredients yourself? It's really good! What materials do you need? Come back and help me and Xiaoxin make one too!" Qing Yan was not polite to Chen Xin either.

Chen Xin nodded and agreed. It was just a piece of protective clothing. Even if survival points were needed to upgrade, it would not cost a few survival points if Mo Qingyan provided materials.

"By the way, this is an oxygen generator made for you. I told you about the oxygen problem before. I was worried that you couldn't handle it here, so I made one for you." Of course, Chen Xin didn't forget the purpose of his visit today. , opened the trunk of his car, and took out the ready-made oxygen generator: "Under the condition of continuous power failure, this machine is enough for Longniang, you and Xin Xiaomei."

I'm curious, how many people will say that the protagonist licks the dog
