"You can actually make this ingredients! It's so amazing!" Mo Qingyan looked at the oxygen generator that was moved out of the car by Chen Xin, and sincerely admired.

When Chen Xin told her that she should pay attention to oxygen issues, Mo Qingyan also heard from Chen Xin how to make a simple oxygen generator by herself. She also planned to do one by herself with her sister Mo Qingxin, but in fact, after she got it done, she found that this was not something that could be made casually.

Facing the oxygen generator that Chen Xin took out, Mo Qingyan was also somewhat moved in her heart in addition to admiring Chen Xin's ability to act.

So she said to Chen Xin half-jokingly: "A Xin, you brought this kind of thing, how should I change it with you? If you exchange it with you, you must not empty my wine cellar? Why don't Xiaoxin and I enjoy it with you?"

When Chen Xin heard Mo Qingyan say this, he didn't say anything, and Mo Qingxin's face turned red immediately.

Although Chen Xin and Mo Qingyan didn't mind such jokes before, it still made Mo Qingxin feel very shy and embarrassed when she said this in front of her.

"Forget it, I don't have such an idea now." Chen Xin shook his head and rejected Mo Qingyan's suggestion: "Give me two bottles of your treasure, and give me two boxes of wine and two boxes of canned food. As for what I really want to have fun, wouldn't it be better to let you two move to my place?"

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 it, I can't tell the ingredients, you're still thinking about hiding the sweetheart in the golden house?" Mo Qingyan didn't know whether it was a glory or a regret when she heard Chen Xin's rejection, but she quickly complained to Chen Xin very exaggeratedly and exposed the topic.

Chen Xin did not continue, but just helped Mo Qingyan install the oxygen generator. After filling it with water, he said to her: "The oxygen generator needs to be continuously powered. If there is no light, the algae inside will not undergo photosynthesis, so it is necessary to maintain power supply. Long Niang, do you have a backup power supply here?"

"Yes, when I was repairing the shelter, I designed a battery pack. 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 power.

Hearing Mo Qingyan say this, Chen Xin nodded with confidence, and said while filling the oxygen generator with water: "Don't change the water in the oxygen generator often, but remember to clean the algae deposited at the bottom to avoid blocking the nozzle at the bottom."

Listening to Chen Xin explaining the precautions for using the oxygen generator, Mo Qingyan nodded while asking Mo Qingxin to record it carefully.

However, while recording the precautions Chen Xin said, Mo Qingxin also asked with concern: "A Xin, I have recorded all the things you said, but where can we get the water algae? In this situation outside, the water algae has died, right?"

"Algae is not that easy to die, and there should be some surviving algae." Chen Xin was naturally prepared for this. He smiled at Mo Qingxin before taking 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 produced from my own oxygen generator. There are rich algae inside. After pouring it into yours, it will reproduce by itself."

"Self-propagation? Don't you need to provide anything else?" Mo Qingxin asked curiously as she looked at Chen Xin pouring a bottle of green liquid into the can of the oxygen generator.

"If you use it normally, you should add nutrients to promote algae reproduction, but if the conditions are limited, you can only do this." Chen Xin shook his head helplessly, but also explained: "But even if it is placed normally, water bodies will naturally produce algae after eutrophication over time, so you don't have to worry about the reproduction of algae.

If the algae inside is really not good, Long Niang, go to Alan or Xiao Ding. I heard them say that the official shelter is also using this kind of algae oxygen generator. They should have nutrient salts for raising algae, just get some."

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

Hearing Chen Xin say this, Mo Qingyan, who is beside him, hurriedly nodded and responded: "I understand, I will ask Aning when I look back."

After turning on the power supply and letting the oxygen generator run, Chen Xin then patted his hands with satisfaction and said to Mo Qingyan: "Okay, it should turn green in one or two days, and oxygen will be produced."

Although he said that, Chen Xin actually had no idea whether there was enough water algae to be produced in one or two days.

After all, his oxygen generator was directly upgraded to the system. The algae inside quickly reproduced after the upgrade was completed. It took only one day to dye the water dark green, and the efficiency was far beyond the normal algae proliferation rate.

However, things like water algae are indeed easy to grow. If you keep a puddle, the water will turn green in just a few days, so Chen Xin is not worried that the oxygen generator at Mo Qingyan's house will not work properly.

Seeing that Chen Xin had installed the oxygen generator, Mo Qingyan took the initiative to say to him: "Thank you for your hard work, Ah Xin, stay for lunch and go back before going back!"

"Ah...? Oh! OK!" Chen Xin was stunned for some reason. After Mo Qingyan shouted, he came to his senses and agreed to her proposal to stay for lunch.

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

I noticed Chen Xin's condition, but Mo Qingyan and Mo Qingxin didn't say much, but just asked a question with concern, and saw that Chen Xin had no problem, he didn't care anymore.

What Mo Qingyan took out for lunch was still the emergency food reserved before the disaster. In addition to the three-point self-heating food, there was also a canned pork and the cabbage exchanged by Chen Xin for her.

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

Compared to storing rice, frozen meat or dehydrated vegetables, emergency foods can be stored for a longer time, and another advantage is that they save fuel and water.

After all, emergency foods are all self-heating, and they can be heated by themselves with just one sip of water. Compared with raw ingredients such as rice that also require boiling water, it is both convenient and reliable in a doomsday environment.

Raw ingredients such as rice and frozen meat must be cooked if they want to enter the mouth, and they need to consume valuable drinking water and fuel. They also rely heavily on storage for their own storage.

Rice is slightly better. Ingredients like frozen meat must be stored in a low-temperature frozen environment for a long time. They are far less than the lasting thing that emergency food can be stored in a place.
