Humanity is missing, luckily I have billions of clones

At this stage, Li Qingsong has divided his total of 12 bodies into two groups.

Two of the bodies were fixed in the Deep Space Spacecraft to prevent accidental annihilation on the surface of Luoshen. At the same time, the two bodies also took on the task of learning, constantly searching for information from the Deep Space Spacecraft's database and learning continuously.

The two bodies are in an alternating rest mode. Whenever one body falls asleep, Li Qingsong's consciousness will transfer to the other body and continue to study and remain conscious.

Among the ten clones on the surface of Luoshen, two of them became firemen, responsible for adding fuel to the steam engine.

Of course, they also take turns to rest. A clone works 12 hours a day, and the remaining 12 hours are used for sleeping, eating, going to the toilet, taking a temporary rest, etc.

Two clones are just enough to keep busy.

There are eight clones left, four of whom are responsible for driving the planetary rover to search for and mine minerals, continuously bringing back oxygen ore and tholin ore for use in the steam engine. They are also responsible for driving the landing spacecraft to and from space and the surface, and transporting supplies and equipment.

In the end, only the last four clones were left - if they took shifts, only two clones would be responsible for the construction of the internal facilities of Base No. 1 at the same time.

This made Li Qingsong sigh in his heart: "The number of clones is still too small, not enough at all."

But there is no other way at this stage. Without sufficient food and energy supply, if we dare to increase the number of clones without authorization, they will all starve to death.

No matter how slow the progress is, Li Qingsong can only calm down and take it slow.

After half a month of hard work, the planting racks in Base No. 1 were roughly built. The fluorescent lamps removed from the Deep Space Spacecraft were also installed on the racks.

There are two hundred of them in total, and the power of each fluorescent lamp is 50 watts. Therefore, the power consumption of the fluorescent lamps alone reaches ten degrees per hour.

In addition, the batteries of the space suit need to be charged, the rover also needs to be charged, and there will be other electricity demands from time to time, which immediately reaches the upper limit of this steam engine.

At most, even if running at full power, the installed capacity of this steam generator is only 13 kWh.

"Take your time."

Li Qingsong thought: "Let's take care of Base No. 1 first."

The planting rack was set up, the fluorescent lights began to shine, and the nutrient solution was prepared using the powder ground by the grinder.

The waste materials used in preparing the nutrient solution, such as small stones, were not thrown away. Instead, they were evenly spread on the planting racks by Li Qingsong to serve as fixation for the plant roots.

The clone carefully poured the nutrient solution rich in plant growth onto the tray, and another clone just as carefully inserted the sweet potato vines into the fixed object.

It took another day to complete this task. Only when he felt that the clone was extremely hungry did Li Qingsong manipulate him to take something to eat.

The other clone had abdominal cramps and had to go to the bathroom first.

As for the feces he excreted, that certainly could not be thrown away.

These feces are of great use to Li Qingsong.

They are rich in organic matter and microorganisms required for the growth of various plants and are indispensable materials for preparing nutrient solution.

During this period, Li Qingsong carefully collected the feces of each clone and never threw any away.

After finishing all this, Li Qingsong finally breathed a sigh of relief.

The next thing to do is to take care of the sweet potatoes on a daily basis and wait for them to mature.

At this moment, the total area of ​​Base No. 1 is 200 square meters. Except for some necessary functional facilities, such as toilets, nutrient solution preparation rooms, and necessary passages, the remaining total of about 160 square meters has been designated as a planting area.

The planting rack has four layers, so the total planting area reaches 640 square meters, which is just less than one acre.

Of the 640 square meters, Li Qingsong planted 600 square meters of this specially cultivated sweet potato.

This kind of sweet potato only takes three months to mature and has a high yield.

Experimental data from Earth show that, under ideal circumstances, the maximum yield of this sweet potato can reach 6,500 kilograms per mu.

But the conditions here on Luoshen Star are simple, and Li Qingsong certainly can't make it so productive. According to his estimate, the yield can be 70% of the maximum yield, which is about 4,500 kilograms per mu.

In this way, it is estimated that each season, these 600 square meters of sweet potatoes can yield about 4,000 kilograms of fruit.

The 12 bodies, including the main body, need an average of 3 kilograms of raw sweet potatoes as staple food every day to maintain their physical strength in the absence of meat supply.

Of course, eating only sweet potatoes is definitely not enough. However, there are some other food and meat reserves in the Deep Space Spacecraft, which can be supplemented. Li Qingsong only intends to use sweet potatoes as the staple food to reduce the consumption of other foods.

In this way, 36 kilograms of sweet potatoes need to be consumed every day, and in three months, about 3,000 kilograms of sweet potatoes will be consumed.

In this way, the output of Base No. 1 can not only fully cover the current consumption, but also have some surplus.

Not only that, sweet potato leaves can also be used to feed pigs, cattle, sheep, chickens, ducks and geese, and can even be eaten as vegetables by humans, thus providing more food sources.

Li Qingsong planted some oil-producing crops such as peanuts and rapeseed on the remaining 40 square meters of planting area. However, because the planting area is too small, they can't produce much, and they are just an additional supplement.

"Once this batch of sweet potatoes is harvested, my food reserves will be much more abundant, and I can start breeding a new batch of clones."

Li Qingsong thought silently: "When the time comes, I will build more bases to produce more food and feed more clones.

Once there are enough clones, we can try to develop industry, slowly starting from scratch and promoting industrial and technological development."

Looking at the planting racks in front of him where no crops have grown yet, Li Qingsong's 12 heads are filled with imaginations about the future.

The clones spent three months studying, mining, transporting, caring for plants, and adding fuel to steam engines.

During this period, Li Qingsong witnessed every step of the growth process of these sweet potatoes. He watched them sprout branches and leaves from the tender buds, and watched the sparse sweet potato vines gradually cover the planting racks. Sweet potato fruits also gradually grew from the roots, and then grew bigger and bigger.

Today is a good day. On this day, every Li Qingsong is in high spirits, and walks with the wind.

Because the three months have passed, today is the day to harvest the sweet potatoes!
