In the preparation room, Chen Xin put on the protective clothing and fastened the protective mask on his face, and sorted out the equipment he wanted to bring.
Originally, Chen Xin planned to ask Qin Lan to bring the prepared oxygen concentrator to Mo Qingyan when she 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 stuffed into the compartment of the SUV with the back seat folded down, and it has also been bundled to ensure that it will not roll because it is round.
After all, this thing is made of glass, and it will break if it gets bumped.
The equipment Chen Xin brought was still the flashlight and folding hiking poles that he used last time when he went out, but this time the pistol he carried was changed from the one he made to the pistol he got from Qin Lan.
Originally, Chen Xin did not plan to bring a gun because he was going to the city, but after hesitating for a while, he still put the gun on his body. He was 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 reserved before. The quantity was not large, and it would be gone once it was used up. However, considering that the oxygen content outside was now lowered and there might be a risk of hypoxia, he still put a bottle on him to avoid any eventuality. When encountering a situation of insufficient oxygen, you won’t be at a loss.
After sorting out his equipment, Chen Xin opened the door to the upgraded shelter and drove out.
After turning around and closing all the doors, Chen Xin set off on his way to deliver the oxygen concentrator to Mo Qingyan.
In the rearview mirror, the door of the shelter looked much more presentable than before. It no longer looked like a pit had been dug and the door was buried in. Instead, it looked like a solid door with cement reinforcements all around.
In fact, this uses reinforced concrete, not just cement. Although it looks a lot more conspicuous, it is not without its benefits.
Sturdy is of course the most important thing, and in addition it can facilitate drainage.
Although as the temperature gets colder and colder, the main precipitation has turned into snow, but the solid cement floor is always easier to drain than the ordinary mud floor, and it is easier to maintain.
Driving towards the city, Chen Xin had to turn on the lights this time instead of turning them off like when he came out before.
Because the roads have become somewhat damaged compared to when Chen Xin came out before, and with the rainfall in the past few months and the occasional falling meteorites, there are a lot more roads on the road than when we last entered the city. clutter.
This slowed down Chen Xin's progress a lot. The car was equipped with an oxygen concentrator made of glass. If it was bumpy too much, it would be easily damaged. In order to protect the oxygen concentrator, Chen Xin could only slowly choose a relatively smooth road. Walk.
When Chen Xin entered the city before, most of the buildings in the city were only burned to a disgraceful appearance, but the overall structure was still there.
But this time when he entered the city, Chen Xin clearly saw that some houses had collapsed.
That was the collapse caused by the impact of the meteorite. As time goes by, the dust and meteorite debris floating in the sky will gradually fall. The larger the volume, the faster it falls. What falls now are the larger pieces of debris.
In a sense, this is a good thing. Debris continues to fall, and the dust clouds in the sky will not be so thick. After one to two years, the earth will gradually return to sunlight.
For today's humans, returning from no light to a low-light environment in one or two years can greatly improve the current situation of human existence.
However, it will take a long time to restore normal light. This dust will continue to cover the sky for at least several decades, at least two generations.
As for restoring 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 restored.
For the earth, this may be just a short moment, an insignificant moment in the billions of years of the earth. Although this moment caused great damage to the earth's ecology, it is still insignificant to the entire earth. .
But for humans, this is a doomsday catastrophe that will last for several generations and affect the survival and development of the entire civilization. It has to be said that humans claim to be the masters of the earth, but in fact, compared to the entire earth, humans 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 Chen Xin came, Mo Qingyan's home has obviously undergone some reinforcements and renovations. 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 storefronts facing the street were originally The doors and windows of the house were also nailed shut, and simple barricades made of triangular iron and wood were placed at the iron gate leading to and from the backyard.
Although it is a bit conspicuous, it can also be regarded as a security guarantee. At least it is not that simple if someone wants 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 moved the roadblock before signaling Chen Xin to drive in.
After Chen Xin drove in, the Mo sisters quickly moved the roadblock back to its original position and closed the door again.
Still driving into the elevator like last time, and going 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 pretty good! Where did you buy it? Why didn't I see you wearing it last time?" Mo Qingyan looked at Chen Xin's protective clothing and couldn't help but show envy.
Although she also has protective equipment, it is obviously not as good as Chen Xin's protective clothing that looks very professional at first glance.
Moreover, all she had was a protective mask, tactical poncho, and anti-cut gloves, which were very different from Chen Xin's protective clothing that covered almost everything from head to toe.
Hearing Mo Qingyan ask about the protective clothing he was wearing, Chen Xin lifted the hat on his head and then replied: "I changed it myself. If you are jealous, Long Niang, you can give me the materials and I will help you." Change one thing too.”
"Oh oh oh! Did you make the ingredients yourself? You did a great job! What materials are needed? Come back and help me and Xiaoxin make one too!" When Chen Xin said that he could help make one, Mo Qing Yan was not polite to Chen Xin either.
Chen Xin nodded and agreed. It was just a protective suit. Even if it required survival points to upgrade, it would only cost a few survival points if Mo Qingyan provided the materials.
"By the way, this is an oxygen concentrator made for you. I told you about the oxygen problem before, and I was worried that you wouldn't be able to cope with it, so I made one for you." Of course, Chen Xin did not forget the purpose of his visit today. , opened the trunk of his car, and took out the completed oxygen concentrator: "This machine is enough for you and Miss Xin, Long Niang, as long as the power supply is uninterrupted."
