Doomsday Bunker Upgrade Chapter 88: Sudden distraction

　　 "You can 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 oxygen problems, Mo Qingyan also heard from Chen Xin how to build a simple oxygen generator by herself, and planned to do it herself with her sister Mo Qingxin. One, but after actually handing it, I realized that this is not something that can be made casually at all.

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

　　 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? Or me. Cool off with Xiaoxin?"

Hearing what Mo Qingyan said, Chen Xin didn't say anything, 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 cool it off, 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 canned food will do. As for I really want to have a good time, wouldn't it be better for the two of you to move in with me?"

　　 Although it is said that even if something really happens between him and Mo Qingyan will not affect their relationship, Chen Xin still wants to hold on to the bottom line.

　　 "Fuck, you can'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 faced Chen Xin exaggeratedly. Tucao up, exposing this topic.

　　 Chen Xin did not continue, 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 will not be able to photosynthesize, so be sure to keep the power supply. Longniang, 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 fully charged, and I also have a generator." Mo Qingyan nodded, indicating that there is no problem with the electricity.

　　 Hearing Mo Qingyan say this, Chen Xin nodded in relief, and said while filling the oxygen concentrator: "The water in the oxygen concentrator does not need to be changed frequently, but the algae deposited on the bottom should be cleaned and avoided. Block the spout at the bottom."

　　 Listening to Chen Xin's explanation of the precautions for the use of the oxygen concentrator, Mo Qingyan nodded her head and asked 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? Outside now. In this case, the algae are all dead, right?"

　　 "Algae is not so easy to die. There should still be algae that survived." Chen Xin was naturally prepared for this, and after a smile at Mo Qingxin, he took out a bottle of green in his car. Liquid: "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 It will reproduce itself."

　　"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 can only be done." Chen Xin shook his head helplessly, but also explained: "But even if it is placed normally, it will take a long time. Algae will naturally produce after the water body is eutrophicated, 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, Dragon Lady. I heard from them before that this kind of algae oxygen generator is used in the official refuge, and they should have algae cultivation. Just get a little bit of nutrient salt. "

　　 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 took note of it.

　　When Chen Xin said this, Mo Qingyan on the side nodded and responded: "I know, I will ask Aning later."

　　 turned on the power and started the oxygen generator, 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. ."

Even though he said that, Chen Xin actually had no idea whether enough algae could be produced 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 into dark green, which is far more efficient than normal algae proliferation. .

　　 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~ IndoMTL.com~ So Chen Xin is not worried about this system of Mo Qingyan’s house. The oxygen machine is not working properly.

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

　　 "Ah...? Oh! Okay!" Chen Xin didn't know why he was stunned. After Mo Qingyan called out, he came back to his senses and agreed to her proposal to stay for lunch.

Although Chen Xin agreed, but when he was waiting for Mo Qingyan to cook, he always seemed a little lost, as if he was 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, they 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 something that can be stored for years and decades is really useful in this environment.

　　 Compared with storing things like rice, frozen meat or dehydrated vegetables, emergency food can be kept 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 foods such as rice that needs to be boiled, it is more convenient and reliable in the doomsday environment.

　　 And raw food materials such as rice and frozen meat don’t say that they must be cooked if they want to 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. Food materials like frozen meat must be kept in a low-temperature freezing environment for a longer period of time, which is far less durable than emergency food that can be stored in a place. .
