Doomsday Bunker Upgrade

　　 Put on the protective clothing and buckle the protective mask on his face in the preparation room, Chen Xin sorted out the equipment he wanted to bring.

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

　　 The entire oxygen generator has been stuffed into the compartment of the SUV with the back seat down, and it has also been **** to ensure that it will not roll because it is round.

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

　　 The equipment Chen Xin brought was still the flashlights and folding trekking poles used last time when he went out, but this time the pistol he was wearing was replaced by the one he made from Qin Lan.

　　 Originally, Chen Xin thought that he was going to the city and didn't plan to bring the gun, but after hesitating for a while, he put the gun on his body. This is responsible for his own safety.

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

This was the bottled oxygen he had previously reserved. The quantity was not large and there was no more when it was used up. However, considering that the oxygen content outside is now lower and there may be a risk of hypoxia, he still put a bottle on his body to avoid any accidents. When there is insufficient oxygen, there is no way to think.

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

　　 Turning around and closing all the doors, Chen Xin set off on the road to deliver the oxygen generator to Mo Qingyan.

　　 In the rearview mirror, the door of the refuge is much more presentable than before. It is no longer the appearance of dug a pit and bury the door in, but a solid door reinforced with cement around it.

　　 In fact, this is all reinforced concrete, not just cement. Although it looks conspicuous, it is not without benefits.

　　Sturdiness is of course the most important thing, besides, it can also facilitate drainage.

　　Although as the temperature gets lower and lower, the main precipitation has turned into snow, but a solid concrete floor is always easier to drain than ordinary mud and easier to maintain.

　　 drove the car towards the city, and Chen Xin had to turn on the lights this time, instead of turning off the lights as before.

Because the road has become a bit damaged compared to the time when Chen Xin came out, and with the rainfall of the past few months and the occasional meteorite falling, the road has a lot more than when it entered the city last time. Debris.

This made Chen Xin's progress a lot slower. The car was equipped with an oxygen concentrator made of glass. It was too bumpy and it was easy to bump. In order to protect the oxygen concentrator, Chen Xin could only pick a relatively flat road slowly. go.

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

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

　　 That is the collapse caused by the impact of a meteorite. 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 the larger pieces of debris are falling.

　　 This is also a good thing in a sense. 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 restore sunlight.

　　 For the current human beings, the recovery from no light to low light in one or two years can already greatly improve the current situation of human existence.

　　 However, it takes a long time to restore normal light. This kind of dust covering the sky will last for at least several decades, at least two generations.

　　 As for the restoration of the earth’s ecology to its original state, it will take even longer. It may take hundreds of years for the earth’s ecology to be unable to recover.

For the earth, perhaps this is just a short moment, 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. .

It's just that for humans, this is a doomsday catastrophe that lasts for several generations and affects the survival and development of the entire civilization. It has to be said that humans call themselves the masters of the earth, but in fact, compared with the entire earth, humans are so. Small and fragile.

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

Compared with the time when Chen Xin came last time, Mo Qingyan’s house has obviously undergone some reinforcement and renovation. There is an extra circle of barbed wire on the fence, and the iron gate can be seen to be reinforced. Even the facade of the previous store facing the street was originally The doors and windows of her were all nailed to death, and the iron gates in and out of the backyard were put on simple roadblocks made of triangle iron and wood.

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

　　 After receiving Chen Xin's call, Mo Qingyan and Mo Qingxin opened the iron gate together ~www.NovelMTL.com~ after removing the roadblock, they signaled Chen Xin to drive in.

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

　　 Still drove the car into the elevator like last time, and got down to the refuge with the Mo family sisters. Chen Xin got out of the car and took off the mask on his face.

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

　　 Although she also has protective equipment, it is obviously not as good as Chen Xin's protective suit, which is very professional at first glance.

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

When Mo Qingyan asked about her protective clothing, Chen Xin lifted the hat on her head, and then replied: "I changed it myself. If you are envious of Long Niang, 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 so good! What materials do you need? Help me and Xiaoxin make one too!" Hearing Chen Xin said that he could help make one, Mo Qing Yan was not polite with Chen Xin either.

　　 Chen Xin nodded and agreed. It was just a protective suit. Even if it needed survival points to upgrade, it wouldn't take a few survival points if Mo Qingyan provided the 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 could not deal with it, so I made one for you." Of course, Chen Xin did not forget his purpose of coming today. , Opened the trunk of his car and moved the completed oxygen generator out of it: "In the case of uninterrupted power supply, this machine is enough for you and Miss Xin."
