Chapter 68: The temptation of cabbage

The drizzle has been falling, neither getting bigger nor going to stop.

Although the protective clothing is very effective in keeping warm, Chen Xin

still feels a bit of coolness.

"Whhhhhhhh..." Chen Xin's gasping sound was a bit thick. Although the

protective mask could effectively block the harmful components in the air, it

also affected breathing.

It was okay before, but now as Chen Xin's breathing speeded up after walking

for a while, he felt a little breathless.

Chen Xin wanted to find a place to sit down and take a break and breathe

calmly, but watching the rain and sludge everywhere on the ground, he decided

to continue walking.

After all, it was only a little panting. When Chen Xin traveled to Shu, he had

a similar experience, so it would be better to walk a little slower.

But this also made Chen Xin wonder if he was really lacking in exercise as Qin

Lan said. When he traveled to Shu, it was because of the high altitude and the

altitude sickness caused by the thin air that made him breathe.

Is it true that my physique has really deteriorated because I have been

neglecting exercise in the past few years as a professional online writer?

Chen Xin had such suspicions. He couldn't help but wonder if he should get a

human generator to put it in the shelter. When he was fine, step on the human

generator, which can generate energy and exercise.

But just when Chen Xin was thinking like this, he suddenly stopped and raised

his head to look at the sky.

The rain fell on the face of the protective mask, leaving ugly stains, but

Chen Xin still stared at the sky and the thick dust cloud on the gloomy dark

sky.

"Damn it! It's hypoxia!" Chen Xin's mind is not stupid, he just subconsciously

ignored this question.

Who would care about the oxygen we breathe all the time? I am afraid that only

when you really can’t breathe, will you realize that you need oxygen?

When preparing for the construction of the evacuation before the disaster,

Chen Xin also subconsciously ignored this issue, and just prepared an oxygen

cylinder in the evacuation shelter.

But now when he realized that he was experiencing a lack of oxygen, he

realized that the plants on the local surface were burned by the fire and the

sky lost the sunlight. The air that we used to be most used to have become the

need for survival. The biggest problem facing.

People need oxygen to live, and any activity of the human body also needs

oxygen to maintain, and the more intense the activity, the more oxygen is

consumed.

Without the photosynthesis of natural plants, the oxygen in the atmosphere

will gradually decrease as the surviving humans consume it.

Unless the dust clouds in the sky dissipate and the sun shines on the earth

again, allowing new plants to sprout for photosynthesis, the process will be

irreversible.

The surviving humans want to survive, but they can only find a way to produce

new oxygen.

Chen Xin himself is not worried about this problem. There is a planting

greenhouse in his refuge. Under the illumination simulated by the fill light,

all crops will still photosynthesize, which is still enough to maintain his

oxygen consumption.

As for the official refuge, Chen Xin thinks that the country should take this

issue into consideration. The only uncertainty is whether the country can

solve this problem perfectly.

After all, what the country has to consider is all the survivors in the

country, not the issue of a certain shelter.

Common oxygen production methods include physical oxygen production and

chemical oxygen production. In simple terms, physical oxygen production is to

collect oxygen in the air to use it where oxygen is needed; while chemical

oxygen production is through a chemical reaction. The oxygen in carbon dioxide

or other raw materials containing oxygen is reduced to form new oxygen.

Both of these methods were widely used methods of oxygen production before the

disaster, but in the current end times, these two methods are not so

applicable.

Physical oxygen production requires a lot of electricity, and only extracts

the original oxygen in the air. This method is not suitable in the current

environment where the oxygen content in the atmosphere is gradually

decreasing.

Although chemical oxygen production does not have the disadvantages of

physical oxygen production, it also has shortcomings, that is, chemical oxygen

production requires chemical agents, and the cost is high, which is not

suitable for large-scale application.

Therefore, if the Yan State government wants to solve this problem, it can

only use methods other than these two methods to solve it.

"Finally completed the task!"

The SWAT team that completed the ** of the oxygen production equipment

returned to the shelter under the police station, and everyone relaxed.

Although most of the SWAT team members don’t know what the supplies they are

escorting, but seeing the armored train at the railway station and the **

formation this time, they can guess how important this is.

So when escorting these supplies, everyone is actually very nervous.

Now that the task is finally completed, everyone is naturally relieved.

A group of people talked and laughed towards the area where the SWAT team was

located. Although this mission was not tiring, but under high mental stress

~www.mtlnovel.com~ everyone was a little hungry.

Although the food in the refuge is not very good, after completing the task,

there is something to fill the stomach after all is a happy truth.

But because the food currently eaten in the evacuation shelter is mainly

emergency food stocked before the disaster, although there is a canteen, it is

actually only used to distribute fixed food, and there is no fire for cooking.

After all, fuel is precious now, so it’s a bit luxurious to use it for

cooking.

As for the mushroom cultivation greenhouses and the artificially raised mice

and breadworms, although these foods have gradually begun to appear in the

recipes of the refuge, they have not yet reached the point where the SWAT

members can only eat these. .

"What do you have to eat today?" A special police member hooked the shoulders

of a nearby friend and asked him.

"I think it was fried lamb with green onions. Yesterday's was shredded pork

with Beijing sauce. How can I change my taste today."

The companions responded to his words, sounding as if the food was ok, but in

fact they were talking about the taste of self-heating food.

In the two months after the disaster, except for mushrooms and rat meat, it

has been a long time since everyone saw fresh food.

Another SWAT team member interrupted: "I think we should have cabbage soup

today, but we came back with a box of cabbage yesterday! A whole box of fresh

cabbage!"

"No! I carried the pillar together, and it would cost two hundred catties!"

When a special police member who also carried vegetables yesterday said the

cabbage, his eyes were already bright.

Not everyone knows the news of fresh vegetables. After learning about it, many

SWAT team members cheered excitedly: "Oh oh oh! I haven't smelled cabbage for

two months!"
