In this remote corner of the solar system, on this small and cold planet, Zhao Changxing's life seemed to have been fixed in orbit, year after year, day after day.

The construction of Humanitarian Base No. 1 is progressing steadily, and the children are growing up slowly. Zhao Changxing witnessed the first time that the babies have the ability to turn over. This honor was obtained by Sun Caiyun and the first time that the babies have the ability to sit stably. This honor was obtained by Zhao Ye, the eldest brother of all babies.

As for the first one who could crawl on the ground, their second sister, Qian Yue. At this time, the other babies just lay there on their stomachs, stomping their hands and feet.

When Qian Yue hummed an unknown voice in her mouth, she crawled over from a few meters away from Zhao Changxing, and laughed after Zhao Changxing picked her up, Zhao Changxing was very relieved.

At this time, they could no longer stay in the nursery room, but moved to another room. The baby who could crawl just now was at the time of the strongest curiosity. They wanted to hold anything in their hands and put it in their mouths to explore. In addition, they did not have enough control over the body, which was easy to cause danger. Therefore, the hygiene standards in this room were extremely high, and there was no hard and angular thing.

There are ten robot aunts who can move here to wait for them all the time. Whether they are hungry, pulled, urinated, or sleepy, they will go up to deal with it at any time. Usually, they will let them play here freely, play with each other, or play with toys.

They are growing up here slowly, accepting preschool education courses formulated by Earth experts and implemented through robot aunts. Sometimes Zhao Changxing will come in and play with them after disinfection. This is the happiest and most relaxing time for Zhao Changxing.

Gradually, they learned to walk and speak. When Qian Yue represented all the children and shouted "Dad" to Zhao Changxing for the first time, Zhao Changxing hugged her and kissed her more than a dozen times, and she giggled.

At this time, the construction of Humanity No. 1 Base has made considerable progress. The laying of the main frame has been completed by one-third, almost half of it. Zhao Changxing has decided that when it reaches half, a new soilless cultivation workshop and animal husbandry workshop will be built here, and then the five rooms of the first phase of the building will be demolished and all building materials will be integrated into the formal Humanity No. 1 Base.

This will result in no grain output for about three months, but Zhao Changxing is not worried. In the past two years, he has accumulated enough food and is completely enough to eat.

After Feng Yu, who was speaking the latest, could also call him dad, Zhao Changxing officially started the construction process of a new soilless cultivation workshop.

The soilless cultivation workshop is an important part of the Humanity No. 1 base. In the future, a large part of people's food will be obtained from here, and it will not be too much attention.

The new soilless cultivation workshop is located in the northeast corner of Humanity No. 1 Base, occupying nearly one-fifth of the total available area inside the entire base, about 2,300 square meters. This is undoubtedly a huge leap compared to the two pitiful soilless cultivation workshops with a total area of ​​200 square meters in the first phase of the project.

Even if it is converted into a unit of commonly used arable land on the earth, there are nearly four acres of land.

Among these 2,300 square meters, Zhao Changxing plans to divide it into ten areas, each area has an independent environment, and can plant ten types of crops with similar environmental needs.

Among these areas, the rice planting area is as high as 300 square meters. After adopting the double-layer planting method, the area doubles to 600 square meters. They are ripe every three months and can be planted for four seasons a year. In total, they can harvest almost three tons of rice.

The wheat planting area is 200 square meters. The double-layer planting method is also used to double the area to 400 square meters. The growth cycle of genetically modified wheat varieties is about three months, and the year is also four seasons. The total output per year is expected to reach about 1.5 tons.

Of course, Zhao Changxing does not have 400 square meters of wheat seeds available for planting, but that doesn't matter. At this moment, he has used those limited seeds to plant in the soilless cultivation workshop at this moment. After the new workshop is built, the seeds will be completely enough.

You know, in order to save enough seeds, he didn't even want to make a bowl of noodles or a steamed bun to eat, and left all the wheat he had harvested before as seeds.

The remaining extremely important crop is soybeans, and its planting area will also be increased to 600 square meters. After double-layer planting, it will be 1,200 square meters, with an annual output of up to 2.5 tons.

Then there is corn. The status of corn is also very important, but its importance is not reflected in its food, but as feed for animals. With corn, the breeding of cattle and sheep can be put on the agenda.

Zhao Changxing also allocated 500 square meters of its planting area. Of course, this thing is too tall and cannot be used to use the double-layer planting method. It is a real 500 square meters. The annual output is about 0.7 tons. However, including the corn cob and the weight of the plants, it should be enough. Besides, the animals are not just eating this, and there are other feeds to supplement it.

This consumes a total of 1,600 square meters of area, and the remaining 700 square meters of area is relatively mixed. Various types of vegetables, such as eggplant, beans, cucumbers, spinach, lettuce, cabbage, peppers, etc., as well as rapeseed, sunflowers, peanuts, cotton, etc., as well as fruits, such as pineapple, strawberries, etc.

Zhao Changxing even planned to plant some more trees. Of course, these trees have been dwarfed and will not grow too high and the ceiling will break through.

There are apple trees, pear trees, and the most important rubber trees.

Trees have a long growth cycle and must be planted in advance.

These trees cannot be planted by soilless cultivation. They have to use soil and then water and fertilize regularly. There is naturally no soil on the Tinder spacecraft, but the so-called soil can be prepared with sand and various humus, organic matter, etc., and the sand can be collected directly from the Sedna Star, which is not difficult.

In addition to the soilless cultivation workshop, there is an animal husbandry and aquaculture area. Due to the area limited, Zhao Changxing certainly cannot use free-range farming methods and can only be kept in captivity.

Raising chickens, ducks and geese is of course the breeding method that stays in a cage for the rest of your life without seeing the light, which maximizes the area saving and improves the breeding efficiency. As for taste and other things - humans have reached this point, are they qualified to pursue taste?

Raise more chickens. The meat of this thing is amazing, grows faster, and can lay eggs. It is really the only way to quickly improve your living standards. As for ducks and gooses, you can raise them less and occasionally use them as a taste adjustment. Just eat them easily.

Another important breed is pigs. Whether adults or children, you have to eat more meat to be healthy. Vegetarianism is absolutely not feasible here.

The cows also have to be raised. This thing can not only eat meat, but also produce milk. There is not much reserve of milk powder in the Tinder spacecraft, and Zhao Changxing doesn't want the next generation of children born to have to grow up with rice paste. Even if he doesn't have the equipment on hand and cannot make milk powder, drinking fresh milk after sterilization is still much better than rice paste.

In addition to pigs and cows, sheep should also be raised appropriately. As for donkeys, there is no such condition for the time being.

Apart from livestock, there are aquatic products. For fish, of course, the first choice is four major fish, with high yields and mature breeding technology. As for various fresh seafood, they can only be temporarily delayed.

By the way, we have to open up a place to breed some aquatic plants, such as kelp.

After all the calculations, the animal husbandry and aquaculture area also has to occupy a area of ​​more than 3,000 square meters. In addition to the soilless cultivation workshop, it is a total of more than 3,000 square meters.

With such a large area, even if it is just a modular installation, the task volume is unimaginable. Especially Zhao Changxing still needs to wear a space suit to perform these operations, which is really inconvenient.

But there is nothing he can do about this. He can only work day after day and be busy.

It took him more than half a year to build the framework of these two areas, and then it was time to install various internal equipment. However, before this, he needed to make the living area ready.

With the support of the survival zone, the internal environment of the soilless cultivation workshop and the livestock and aquaculture workshop can directly support human survival. He will be able to take off his space suit, operate and install those parts directly.

The lifesaving area is also an extremely important part of the Human No. 1 Base. In the future, all the energy of Human No. 1 Base will come from here, all water sources will be purified and circulated here, and all air will be the same. This took him several months.

In a blink of an eye, more than a year has passed, and the planned new soilless cultivation workshop and animal husbandry and aquaculture workshop have not been put into operation. This situation made him smile bitterly.

Now, the children are over two years old and are full of energy. Even with ten robot aunts taking care of them, the children's room is always in a mess.

On this day, after the day of work, Zhao Changxing dragged his tired body back to the Torment spaceship again.

As soon as I opened the door of the children's room, a chaotic smell came to my face. I saw toys everywhere on the ground, a few children were shouting and running, a few children were sitting on the ground crying, a few children were waving toys to play monsters and heroes, and ten robot aunts were busy, and it seemed that they were almost hit.

Seeing Zhao Changxing come back, the children looked at him at the same time, then ran over with cheers and surrounded Zhao Changxing.

Facing the sound of "Dad" and looking at the mess in the children's room, Zhao Changxing thought to himself: "Maybe... it's time for the children to go to school."
Chapter completed!
