The last human in the universe

Chapter 13 Milestones

After returning to the Huozhi spacecraft, he played with the children for a while, and after they fell asleep, Zhao Changxing hurriedly fell asleep.On the second day, Zhao Changxing had been busy in the rice workshop all day, and when he came back, he suddenly thought of a problem.

The rice workshop is expected to take more than ten days, and the construction of wheat, corn, and vegetable workshops will take at least a year.But this is not possible, because during this process, the soybean workshop that was built at the earliest may have been sown for three or four rounds. Where are the so many beans harvested?

Several buildings in the first phase of the project were about to be demolished, and it was obvious that grain could not be stored there.

If the storage conditions are not right and the beans go bad, it's a waste.

"It looks like the warehouse needs to be built first. I've been so busy this time, I actually forgot about this."

"Xiaoxi, call out the schedule."

"Good captain."

Xiaoxi coordinated and brought up the schedule, Zhao Changxing frowned and began to revise it.

The construction of a warehouse is not just about building an empty house.Different crops require different storage environments, different temperature, humidity, and even different light requirements.

Just like the storage environment of soybeans and lettuce is obviously different.This means that almost every kind of crop needs a separate storage space, and the warehouse to be built in the future must be divided into at least dozens of different areas, and each area needs to be installed with a separate temperature control system and gas circulation system wait.

This is again a lot of work.In particular, the framework structure of the warehouse has not yet been built, and everything is almost starting from scratch. It may take less than a year to build everything.

"Or... first build the framework, make a good life support system, and then build the storage area for soybeans first. Well, no, the staple food reserves are running out, and the cultivation of rice and wheat, the two staple foods, must be brought up. Schedules, their corresponding storage areas must also be built first.”

After much deliberation, Zhao Changxing still decided to finish the rice and wheat planting workshop first, and then start the construction of the warehouse.Before the warehouse is built, the big deal is to trouble yourself, and transport these things to the Tinder spacecraft for temporary storage.

A month later, the rice seeds and wheat seeds were finally planted, and they could be handed over to Xiaoxi for management.Zhao Changxing then devoted himself to the construction of the warehouse.

Floors, wall panels, trusses, beams, pipes, wiring, etc. were put in place one by one, like magic, gradually pieced together the appearance of the house in Zhao Changxing's hands.

The total area of ​​the warehouse area is about 500 square meters, and the total volume has reached about 1600 cubic meters.Among them, many areas are planned, including meat storage area, staple food storage area, vegetable storage area, oil plant, cotton, fruit and so on.Under each category, subcategories can be further subdivided, and the areas of different categories can be adjusted more conveniently according to later needs.

At this time, the soybeans had already been harvested for a round, and about 700 kilograms of soybeans were brought to the Tinder spacecraft by him, and turned into about 150 kilograms of soybean oil.The remaining soybean meal is temporarily stored, ready to be used as feed for livestock in the future.

In fact, at the stage of realization, Zhao Changxing did not lack soybean oil.The reason why soybean oil is made is purely because the oil and soybean meal are more convenient to store.

This is the disadvantage of not having a warehouse.

Because during the construction process of the soilless cultivation workshop and the livestock and aquaculture workshop, the various pipes and cables extending from the life support area have been reserved for the interface, after the warehouse frame is built, it can be carried out directly. The laying of internal wiring is done.Zhao Changxing estimated the output of various crops in the future, and decided to reserve a storage space of 20 square meters and a volume of about 70 cubic meters for soybeans. Under extreme conditions, about 50 tons of soybeans can be stored.According to the calculation of an annual output of 2.5 tons under current conditions, it is enough for 20 years of storage.

The rice storage area is larger, about 30 square meters in area and 90 cubic meters in volume. Under extreme conditions, it can store 65 tons of rice, which is almost 20 years' output.

The situation with wheat is similar.

Looking at the thick stack of blueprints and various building materials piled up in a mess on the ground, Zhao Changxing sighed: "Don't say anything, let's work."

After that, I plunged into work.

The construction of the three storage areas for soybeans, rice, and wheat took another two months, almost in time for the harvest of rice and wheat.So the empty warehouse ushered in their first batch of residents.About 3 tons of rice and 1.5 tons of wheat were stored.

With the support of the latest technology, these crops can be preserved for at least ten years, and they still have a taste that is not much different from new grains.Even if the taste is bad after ten years, it can still be used to make feed, and it will not be wasted anyway.

Time passed slowly, and more than a year later, the soilless cultivation workshop, animal husbandry and aquaculture workshop, and warehouses were finally built.But right now, they can't all be up and running.Because the new automated nutrient solution preparation workshop has not yet been built.

The nutrient solution needed for the cultivation of soybeans, rice, and wheat still comes from the small automated nutrient solution preparation workshop in the first phase of the project.In order to support its operation, Zhao Changxing had to pull a temporary cable from the human base No. [-] life support area.

But its output is limited after all, and it is the limit to support the growth of these three crops, and it will not work any more.

The construction of a higher output and more automated nutrient solution preparation workshop must begin.

It took about four months to build its frame and lay internal lines. After that, it took more than one month to transfer and connect various lines and connect them from the temporary workshop of the first phase of the project to the current official workshop. month time.

This process has some effect on the growth of the crop, but not much.

After all this is done, the soilless cultivation workshop can finally produce crops at full power, and after they have been produced for a certain period of time and the fruits or plants of various crops have enough reserves, the animal husbandry and aquaculture workshop will also start production.

At this time, the children were already seven years old, and they were all clever and cute, and they had long since lost the red and wrinkled ugly appearance when they were just born.It has been eight years since Zhao Changxing came to Sedna Star.

When he first came here, Zhao Changxing was 27 years old.Both are 35 years old this year.

Zhao Changxing at this moment has not changed much compared to eight years ago, it is simply because of working all year round, his body has become leaner and stronger.

In Human Base No. [-], the completion of the five buildings, the life support area, the warehouse area, the soilless cultivation workshop, the animal husbandry workshop, and the large-scale automated nutrient solution preparation workshop, is a milestone in the construction of the entire base.

Because this means that since arriving at Sedna, humans finally have the strongest backing and conditions to expand their race.Based on ideal conditions, these five buildings can produce 2.5 tons of soybeans, 3 tons of rice, 1.5 tons of wheat, 0.7 tons of corn, 2 tons of potatoes, and more miscellaneous vegetables, as well as meat, chickens, ducks, and geese. The annual output of pigs, beef, sheep, fish, etc. is also in the order of several tons.

According to the calculation that an adult needs to eat about 0.5 kg of staple food every day, which is about 180 kg of staple food a year, when the non-staple food such as fruits, vegetables, meat, eggs, etc. is relatively sufficient. of food, can supply 50 adults for a long time to survive.Of course, children and minors will occupy the majority of Human Base 100 for a long time, and this number can be even larger, [-] people are no problem.

But toddlers and teenagers will always grow up, and food production will need to be expanded again.But there is at least ten to several decades of buffering, and Zhao Changxing has time to slowly solve this problem.It’s really not possible, Zhao Changxing still has the magic weapon of starch reactor, which can be scaled up and directly synthesized starch with carbon dioxide and water. Anyway, there is still a lot of energy produced by the fusion reactor, and the synthesis is enough, even if it is not a long-term solution. Can always temporarily fill the gap.

Looking at the fruits of his labor, Zhao Changxing started planning again.

Given the current population level, i.e. one adult plus ten children, the food production is obviously inexhaustible, and there is a lot of surplus.My original plan was to wait for the first batch of children to grow up before multiplying the second batch of humans, but now it seems that my plan has to be changed.

Maybe... When the first batch of children were a little older, about twelve or thirteen years old, they began to reproduce the second batch of humans?I can completely adjust the education schedule, teach them some knowledge about caring for young children in advance, and then arrange classes in batches. In this way, no matter when, there will always be some children who are in their spare time and can take care of the new children instead of themselves. children born.

Although the age of twelve or thirteen is a little younger, it is now an extreme moment of human civilization, and it is completely feasible for them to take care of small babies.You know, just a few hundred years ago, children on earth, even if they were less than twelve or thirteen years old, could already be regarded as half of the labor force, weeding and watering the fields, mowing grass and herding sheep and cattle, and doing everything.

Besides, I am not letting the children fully take on the important task of raising the next generation.They just need to cooperate with Xiaoxi to complete some routine things. If there is an emergency, such as a child getting sick or injured, they can return to the Pyro spacecraft from Sedna to deal with it at any time.

After thinking for a few days, thinking about every detail of these things, and confirming that this matter is feasible, Zhao Changxing made up his mind.

"It is estimated that it will take a few years for the first human base to be fully completed. Then wait until it is fully completed. At that time, the second batch of human reproduction will begin. Well... the number can be set at 40, no, or Be safe, set it at 30."

Thinking of the scene of 30 children crying together in the incubator, Zhao Changxing subconsciously felt a little headache, but for some reason, he was yearning and looking forward to it.
