    Time passed calmly for a month. During this month, Chen Xin's life did not change much. He woke up from the alarm sound on his mobile phone on time every day, just like in the past, he had to sleep until he woke up naturally every day.

    There is no daylight in the shelter, and it is meaningless to judge day and night by light. In order to prevent himself from falling asleep and not knowing the time, Chen Xin reset the alarm on his mobile phone.

    Since he quit his job to write novels a few years ago, this is the first time Chen Xin has turned the alarm on his phone back on.

    But returning to a regular schedule is 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 time naturally brings about regular work and rest habits. After getting up, brushing his teeth and washing his face, Chen Xin will tear open a generation of self-heating food for breakfast. While waiting for the self-heating food to be heated, he will take advantage of this time to make more than a dozen  Minutes of exercise to exercise your body.

    Wait until the warm-up is completed and breakfast is cooked. Eating at this time will make people more appetizing.

    After eating, Chen Xin will first check the operation of various equipment in the shelter and fill up the generator with oil in the morning.

    After starting the generator to power the entire shelter, he will spend the morning in the greenhouse.

    Although there is no need to weed and remove insects, watering, fertilizing, and loosening the soil still need to be done.

    Needless to say, watering and loosening the soil, although Chen Xin has never done it before, but with the video data in the computer, he can still do it and basically meet the requirements for planting.

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

    The only thing that makes Chen Xin a little bit intolerable is fertilization.

    Chen Xin did not buy chemical fertilizers when he first moved into the shelter. He got the soil in the greenhouse from the vegetable garden of a nearby farmer's uncle. Of course, the soil quality is not a problem, and it is the vegetable plot kept by the farmer's uncle's family. He usually uses it.  I grow vegetables for my own consumption, so no chemical fertilizers or pesticides are used.

    ¡°However, when the farmer¡¯s uncle sold the soil to Chen Xin, he also reminded him that if he wanted to grow delicious vegetables, he must remember to fertilize.

    The fertilization the farmer uncle is talking about is of course not chemical fertilizer, but the legendary farmyard manure.

    To put it simply, this thing is the liquid obtained after fermentation using the black water part introduced before in the shelter water circulation system, and the gas produced during the fermentation process is the legendary biogas.

    Under normal circumstances, biogas digesters are generally built in rural areas. Human and animal excrement, straw and other organic matter are filled into the biogas digester. The decomposition of biogas bacteria produces methane, which can be used for daily cooking, heating, lighting and power generation.

    It is a very common facility in rural areas of Yan State. It was vigorously promoted in the 1990s and used for the treatment of human and animal excrement in rural areas and to improve rural living conditions.

    The black water treatment system in the sewage treatment system installed by Chen Xin uses the same principle. It uses bacteria to decompose the organic matter in the recovered black water, thereby realizing the recycling of water resources. As for the gray water, it contains such things as soapy water and detergents.  The residues of hair lotion and washing powder cannot be added directly to the biogas digester, because these things will kill the decomposing bacteria in the biogas digester.

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

    However, even if biogas energy is not used, biogas digesters can still be used as an important means of sewage treatment, which can effectively decompose organic matter in sewage and speed up the recycling of water resources.

    It¡¯s just the smell of fermentation tanks used for sewage treatment

    Comparing the stinky socks that haven¡¯t been washed in the boys¡¯ dormitory for a month to the fermentation tanks that haven¡¯t been opened for a month, it¡¯s probably the difference between stinky tofu and canned herrings.

    That sour feeling Chen Xin went in wearing his own gas mask, but he still almost shed tears.

    Fortunately, the sewage treatment tank is outside the container room, and Chen Xin considered the smell and turned on the forced ventilation, so the smell would not spread throughout the shelter.

    The recycled sewage that had been fermented for a month was carried by Chen Xin into the planting greenhouse in plastic buckets prepared in advance, and then poured into the soil ladle by ladle.

    Although the taste of this thing is really sour, we have to say that nature is a complete cycle, and it is these organic matter that have been decomposedOnly then can plants thrive.

    After fertilizing, watering came. However, what surprised Chen Xin today was that when he was halfway through watering, there was no water in the water pipe.

    This shocked Chen Xin. He hurriedly ran to the water tank and sewage treatment tank to check, and found that his water tank, which 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 the water vapor in the air was collected even though there was a sewage treatment tank and a water circulation system, but the water was still used up.

    However, when there is no water, there is no water. Although there is still a lot of drinking water for drinking, and only two and a half boxes of purified water have been used, and there is still a lot of stock, 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 water shortage crisis, or use stored drinking water to replenish domestic water.

    Using drinking water to supplement domestic water is the last option that will be done when there is no other way. Chen Xin will not do this if there are other options.

    Without using drinking water to supplement domestic water, Chen Xin has only two choices.

    First, Chen Xin can choose to risk opening the door of the shelter and go out to find fresh water resources.

    A month has passed. The fire caused by the meteorite impact should have been extinguished over time after the sky was obscured by dust and the temperature gradually dropped. There should not be much danger in leaving the shelter now.

    And this in itself was one of Chen Xin's original plans. He would open the shelter a month after entering the shelter, go out to install the antenna of the shortwave radio station, and at the same time get in touch with his companions in other survival groups. If possible, he could also contact people in the shelter.  Let's exchange supplies with some friends in the city.

    "At least Chen Xin can be sure that one of his companions in the city does not have a greenhouse planned. If he brings fresh vegetables there, he can exchange a lot of things with her.

    But there is a problem in doing so, that is how Chen Xin can bring fresh water back.  (Remember the website address: www.hlnovel.com
