Time passed for a month calmly, and Chen Xin's life did not change any more during this month. He woke up from the alarm ring on time every day, just like in the past when he had to sleep until he woke up naturally every day.

There is no sunshine in the shelter, and it is meaningless to judge the day and night by light. In order to avoid not knowing the time when he sleeps, Chen Xin resets the alarm clock on his phone.

This is the first time Chen Xin has turned on the alarm ring on his phone since he resigned a few years ago.

However, returning to the regular routine is also a new experience for Chen Xin. At least he feels that his mental state and physical condition have improved a lot.

Regular work and rest periods naturally bring regular work and rest habits. After getting up, brushing teeth and washing your face, Chen Xin will tear apart a generation of self-heating foods for breakfast. While waiting for the self-heating foods to heat them, he will take advantage of this time to do more than ten minutes of exercise to exercise.

When the warm-up is over, the breakfast is already cooked. Eating at this time will make people feel more enjoyable.

In the morning after dinner, Chen Xin would check the operation of various equipment in the shelter and fill the generator with oil.

After starting the generator to power the entire shelter, he would spend all his morning hours in the planting greenhouse.

Although weeding and insect removal is not necessary, watering, fertilizing, and loosening the soil still needs to be done.

Needless to say, watering and loosening the soil, although Chen Xin has never done it before, with the video materials on the computer, he can still do it in a consistent way, and basically meet the requirements of planting.

Although these vegetables cannot be said to be very lush, they are basically growing up healthily and there is nothing wrong with it.

The only thing that Chen Xin couldn't stand was fertilization.

Chen Xin did not buy fertilizer when he moved into the shelter. He also got the soil in the greenhouse from the vegetable garden of a nearby farmer. Of course, the soil quality is not a problem. Moreover, it is a vegetable field left by the farmers' home. Usually, they grow vegetables for themselves, so they have never used fertilizers and pesticides.

However, when the farmer sold the soil to Chen Xin, he also specifically reminded him that if the vegetables grown are delicious, he must remember to fertilize them.

Of course, what the farmer said about fertilization is not chemical fertilizer, but the legendary...farmer fertilizer.

Simply put, this thing is the liquid obtained after fermentation using the black water part introduced in the shelter water circulation system, and the gas generated during fermentation is the legendary biogas.

Under normal circumstances, biogas tanks are generally built in rural areas, which fill the excrement of humans and animals, straw and other organic matter from humans and animals into the biogas tanks, and methane is generated under the decomposition of biogas bacteria. It can be used for daily cooking, heating, lighting and power generation.

It is a very common facility in rural Yan Country. It was vigorously promoted in the 1990s to treat excrement of people and animals in rural areas and improve rural living conditions.

The black water treatment system in the sewage treatment system installed by Chen Xin also has the same principle. It uses bacteria to decompose and recover the organic matter in the black water to realize the recycling of water resources. As for the gray water, it cannot be directly added to the biogas tank because it contains residues such as soapy water, shampoo and washing powder, because these things will kill the decomposed bacteria in the biogas tank.

Chen Xin had also considered using biogas as energy in the shelter before, but after calculation, he found that his excretion alone was not enough to meet the gas production needs of a biogas pool, so he had to give up this idea and did not use biogas as energy.

However, even if biogas energy is not used, biogas tanks can still be used as an important sewage treatment method, effectively decompose organic matter in sewage and accelerate the recycling and utilization of water resources.

Just the taste of the fermenter used for sewage treatment...

Compared with the smelly socks that have not been washed in a month in boys' dormitory and the fermentation tank that has not been opened in a month, it is probably the difference between stinky tofu and canned herring.

That sour... Chen Xin brought his gas mask in, but he almost burst into tears.

Fortunately, the sewage treatment tank is outside the container room, and Chen Xin took the scent of this thing and turned on forced ventilation, so the smell did not spread throughout the shelter.

The recycling sewage that had been fermented for a month was put into the planting greenhouse with plastic buckets prepared in advance, and then poured into the soil one by one.

Although the taste of this thing is really sour, it has to be said that nature is a complete cycle, and it is these decomposed organic matter that can make the plants grow vigorously.

After fertilization, watering was watering. However, what surprised Chen Xin today was that when he had watered halfway, there was no water in the water pipe.

This shocked Chen Xin and hurried to the water tank and sewage treatment tank to check. He found that the tank that could store three tons of fresh water was empty, and the sewage collected in the sewage treatment tank was only half full.

Looking at the empty water tank, Chen Xin didn't understand why there was a sewage treatment tank and water circulation system that even the water vapor in the air was collected, but he still used up the water.

However, if there is no water, there is no water. Although there is still a lot of drinking water used for drinking, only two and a half boxes of pure water have been used up, and there are still a lot of inventory, domestic water and greenhouse planting water have been exhausted.

Now Chen Xin must find a way to replenish fresh water, otherwise he will fall into a crisis of water shortage, or use stored drinking water to replenish domestic water.

Using drinking water to replenish domestic water is the last choice that you will only make when there is no other way. Chen Xin will not do this if there is any other choice.

If you do not use drinking water to replenish domestic water, there are only two ways to choose in front of Chen Xin.

First of all, Chen Xin can choose to take the risk of opening the door to the shelter and go out to find tamsui resources.

A month has passed, and the fire caused by the meteorite impact should be extinguished with the gradual decline of temperature after the sky is covered by dust. Now, leaving the shelter should not encounter too much danger.

And this is one of Chen Xin’s original plans. He opened the shelter one month after entering the shelter, went out to install the short-wave radio antenna, and contacted his companions from other survival groups. If possible, he could also exchange supplies with several companions in the city.

At least Chen Xin could be sure that a companion in the city was not ready to plant a greenhouse, so he brought his own fresh vegetables and could exchange a lot of things with her.

But there is a problem with this, that is, how should Chen Xin bring Tamsui back.
