Doomsday Bunker Upgrade

　　 "You can actually make this with ingredients! It's amazing!" Mo Qingyan looked at the oxygen generator that Chen Xin had removed from the car, and exclaimed sincerely.

When Chen Xin told her to pay attention to the oxygen problem, Mo Qingyan also heard from Chen Xin how to make a simple oxygen generator by herself, and planned to make one by herself with her sister Mo Qingxin, but In fact, I realized that this was not something that could be made casually after I got my hands.

　　 Facing the oxygen concentrator Chen Xin took out, Mo Qingyan, besides admiring Chen Xin's hands-on ability, was somewhat moved.

So she said to Chen Xin half-jokingly: "Axin, you brought this kind of thing, how should I change it with you? If you exchange wine with you, you can’t empty my wine cellar? How about me and Xiaoxin Cool with you?"

　　 Hearing Mo Qingyan's words, Chen Xin hadn't said anything yet, and Mo Qingxin's face immediately turned red.

　　 Although Chen Xin and Mo Qingyan didn't mind this kind of joke before, it still made Mo Qingxin feel very embarrassed and embarrassed to say it in person.

"Just take it easy, I don't have such an idea now." Chen Xin shook his head and rejected Mo Qingyan's proposal: "Give me two bottles of your treasure, and two boxes of wine for me, two boxes of cans. Saying that I really want to take a break, wouldn’t it be better for the two of you to move to me?"

　　 Although it was said that even if something really happened between him and Mo Qingyan would not affect their relationship, Chen Xin still wanted to stick to the bottom line.

"Fuck, you don't see the ingredients, but you still think of Jinwu Cangjiao?" Mo Qingyan heard Chen Xin's refusal, and she didn't know if she was fortunate or regretful, but she quickly complained to Chen Xin very exaggeratedly. Revealed this topic.

Chen Xin did not go on, but only helped Mo Qingyan install the oxygen concentrator. After it was filled with water, he said to her: "The oxygen concentrator needs continuous power supply. If there is no light, the algae inside There is no photosynthesis, so you must keep the power supply. Long Niang, do you have a backup power supply here?"

　　 "Yes, the battery pack was designed when the shelter was built. It can be used for three days when it is fully charged, and I also have a generator." Mo Qingyan nodded, indicating that there is no problem with the electricity.

Hearing Mo Qingyan's words, Chen Xin nodded in relief, and said while filling the oxygen generator: "The water in the oxygen generator does not need to be changed frequently, but the algae deposited on the bottom should be cleaned to avoid clogging the bottom. spout."

　　 Listening to Chen Xin's explanation of the precautions for the use of the oxygen generator, Mo Qingyan nodded her head while asking Mo Qingxin to record it carefully.

But while recording the precautions that Chen Xin said, Mo Qingxin also asked with concern: "Axin, I have written down all of what you said, but where are we going to get the algae? It's the situation outside. , The algae are all dead, right?"

"Algae is not so easy to die. There should still be surviving algae." Chen Xin was naturally prepared for this. After smiling at Mo Qingxin, he took out a bottle of green liquid in his car: "But you don’t need to look outside. I have prepared it for you. This is the water pumped out of my own oxygen generator. It contains rich algae. After it is poured into yours, it will Reproductive."

　　 "Self-reproduction? Don't you need to provide anything else?" Mo Qingxin asked curiously as she watched Chen Xin pour a bottle of green liquid into the tank of the oxygen generator.

"For normal use, nutrients should be added to promote algae reproduction, but the conditions are limited. This is the only way to do this." Chen Xin shook his head helplessly, but also explained: "But even if it is placed normally, the water will be rich for a long time. Algae will naturally be produced after nutrition, so you don’t have to worry about the reproduction of algae.

If the algae in it really doesn’t grow well, you can go to Alan or Xiaoding, Long Niang. I heard from them before that this kind of algae oxygen generator is used in the official refuge and they should have nutrients for algae. Just get a little bit. "

　　 Qin Lan did mention this to Chen Xin when he came to deliver the goods before, because he himself was also using the algae oxygen generator, so he naturally wrote down the matter.

　　 Hearing Chen Xin's words, Mo Qingyan on the side nodded and responded: "I know, I will ask Aning later."

　　 After turning on the power and letting the oxygen generator run, Chen Xin patted his hands with satisfaction, and said to Mo Qingyan: "Okay, after a day or two, the inside should turn green and oxygen will be produced."

　　 Although he said that, Chen Xin has no idea whether he can produce enough algae in a day or two.

　　 After all, his oxygen generator was directly upgraded from the system. The algae in it reproduced rapidly after the upgrade was completed. It only took a day to dye the water dark green, and the efficiency far exceeded the rate of algae proliferation under normal conditions.

But things like algae are really easy to grow. If a puddle is left alone, the water will turn green in just a few days~www.ltnovel.com~ so Chen Xin is not worried about the oxygen generator of Mo Qingyan’s house. The machine is not working properly.

　　 Seeing that Chen Xin had installed the oxygen concentrator, Mo Qingyan proactively said to him: "Thanks for your hard work, Ah Xin, stay and have dinner at noon and go back!"

　　 "Ah...? Oh! Okay!" Chen Xin didn't know why he was taken aback. After Mo Qingyan shouted, he recovered and agreed to her proposal to stay for lunch.

　　Although Chen Xin agreed, he still seemed a little lost while waiting for Mo Qingyan to cook, as if thinking about something.

　　 noticed Chen Xin's state, but Mo Qingyan and Mo Qingxin didn't say much, they just asked a question of concern, seeing that Chen Xin had no problems and didn't care anymore.

　　Lunch Mo Qingyan still brought out the emergency food stored before the disaster. In addition to the three-point self-heating food, there was also a canned pork and the cabbage that Chen Xin exchanged for her.

　　 I have to say that this kind of thing that can be stored for several decades is indeed very useful in this environment.

　　 Compared to storing things like rice, frozen meat or dehydrated vegetables, emergency food can be stored for a longer period of time. Another advantage is that it saves fuel and water.

　　 After all, current emergency foods are all self-heating types, which can be heated by one mouthful of water. Compared with raw ingredients such as rice that needs to be boiled, it is more convenient and reliable in apocalyptic environment.

　　 And raw food materials such as rice and frozen meat do not say that they must be cooked before they can be eaten, they need to consume precious drinking water and fuel, and their own preservation is also very dependent on storage.

　　Rice is slightly better. Foods like frozen meat can be stored for a longer period of time at least in a low-temperature freezing environment, which is far less durable than emergency food that can be stored somewhere.
