"Ingredients, you still make this! That's amazing! Mo Qingyan looked at the oxygen concentrator that was moved off the car by Chen Xin, and admired it sincerely.

When Chen Xin told her to pay attention to the oxygen problem before, Mo Qingyan also heard from Chen Xin how to make a simple oxygen concentrator by herself, and planned to make one by herself with her sister Mo Qingxin, but in fact, after getting her hands on it, she found that this was not something that could be made casually at all.

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

So she half-jokingly said to Chen Xin: "Ah Xin, you brought this kind of thing, how can I exchange it with you?" If I exchange wine with you, you can't empty my wine cellar? Why don't I and Xiaoxin accompany you to have a good time? ”

Hearing Mo Qingyan say this, Chen Xin didn't say anything, and Mo Qingxin's face on the side suddenly turned red.

Although Chen Xin and Mo Qingyan didn't mind this kind of joke before, really saying it to their face still made Mo Qingxin feel very shy and embarrassed.

"Forget it, I don't have such thoughts now." Chen Xin shook his head and rejected Mo Qingyan's proposal: "Give me two bottles of your treasure, and then bring me two boxes of wine, two boxes of canned food." As for saying that I really want to cool off, wouldn't it be better for you two to move in with me? ”

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

"Damn, can't you see the ingredients, you still think about Jinwu Zangjiao?" When Mo Qingyan heard Chen Xin's refusal, she didn't know whether she was happy or regretful, but she quickly complained to Chen Xin very exaggeratedly and revealed this topic.

Chen Xin didn't continue, but just helped Mo Qingyan install the oxygen concentrator, and only after filling it with water did he say to her: "The work of the oxygen concentrator requires continuous power supply, and if there is no light, the algae inside will not photosynthesize, so you must keep the power supply." Dragon Lady, do you have backup power here? ”

"Yes, when we built the shelter, we designed a battery pack that can last for three days on a full charge, and I also have a generator here." Mo Qingyan nodded, indicating that there was no problem with electricity.

Hearing Mo Qingyan say this, Chen Xin nodded reassuringly, and said while filling the oxygen concentrator with water: "The water in the oxygen concentrator doesn't need to be changed often, but remember to clean up the algae deposited at the bottom to avoid blocking the nozzle at the bottom." ”

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

However, when recording the precautions that Chen Xin said, Mo Qingxin also asked with concern: "Ah Xin, I have written down all of what you said, but where are we going to get algae?" In this situation outside, the algae are all dead, right? ”

"Algae don't die so easily, and there should still be surviving algae." Chen Xin was naturally prepared for this, and after smiling at Mo Qingxin, he took out a bottle of green liquid in his car: "But you don't need to go outside to find it, I have already prepared it for you, this is the water from my own oxygen concentrator, which is rich in algae, and after pouring it into your one, it will reproduce by itself." ”

"Self-reproduction? Don't need to provide anything else? Mo Qingxin watched as Chen Xin poured a bottle of green liquid into the tank of the oxygen concentrator, and asked curiously.

"If you use it normally, you should add nutrients to promote algae blooming, but the conditions are limited." Chen Xin shook his head helplessly, but at the same time explained: "But even if it is placed normally, algae will naturally occur after the eutrophication of the water body for a long time, so you don't have to worry about the reproduction of algae."

If the algae inside really doesn't grow well, Long Niang, you can go to Ah Lan or Xiaoding, I heard them say that the official shelter also uses this kind of algae oxygen generator, they should have nutrients for raising algae, just get a little bit. ”

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

Hearing Chen Xin say this, Mo Qingyan on the side hurriedly nodded and responded: "I know, I'll ask A-Ning when I go back." ”

After turning on the power supply and letting the oxygen concentrator run up, Chen Xin clapped his hands with satisfaction, and said to Mo Qingyan: "Okay, it should turn green inside in a day or two, and oxygen will be generated." ”

Having said that, Chen Xin actually has no bottom on whether there will be enough algae in a day or two.

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

However, algae is indeed easy to grow, and if a puddle is left unattended, the water will turn green in just a few days, so Chen Xin is not worried that the oxygen concentrator of Mo Qingyan's family will not work properly.

Seeing that Chen Xin had installed the oxygen concentrator, Mo Qingyan took the initiative to say to him: "Thank you for your hard work, Ah Xin, stay and eat at noon and go back!" ”

"Ah......? Oh! All right! Chen Xin didn't know why he was stunned for a moment, and only after Mo Qingyan shouted did he come back to his senses and agreed to her proposal to stay for lunch.

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

noticed Chen Xin's state, but Mo Qingyan and Mo Qingxin didn't say anything, just asked with concern, and didn't care anymore when they saw that Chen Xin didn't have any problems.

For lunch, Mo Qingyan took out the emergency food that had been stored before the disaster, in addition to the 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, which can be stored for several years and decades, is indeed very useful in today's environment.

In addition to being able to store things like rice, frozen meat, or dehydrated vegetables, emergency food has the added benefit of saving fuel and water compared to storing things like rice, frozen meat, or dehydrated vegetables.

After all, today's emergency food is self-heating, and it can be heated by itself with just a sip of water, which is convenient and reliable in a post-apocalyptic environment compared to raw ingredients such as rice that need to be boiled.

Raw ingredients such as rice and frozen meat must be cooked in order to enter the mouth, which consumes precious drinking water and fuel, and their own preservation is also very dependent on storage.

Rice is slightly better, and ingredients such as frozen meat can be stored for a longer period of time at least in a low-temperature and frozen environment, which is far less durable than emergency food that can be stored in a place.
