Humanity is missing, luckily I have billions of clones.

Chapter 167 20 trillion!

Since we have decided not to give up scientific research during the voyage and to keep one billion clones awake at all times, there is one thing we have to consider.

Li Qingsong must create an environment as suitable as possible for human survival. Otherwise, not only will the clones' work efficiency be affected, they may also become sick, injured, enter a state of aging early, or even die.

In space, it is not easy to replenish clones on a large scale.

Regarding the living environment, air, temperature, and air pressure are all important, but there's one most important aspect: gravity.

In the solar system, every planet has its own gravity. Some are larger, some are smaller, but it's there. And the human body thrives in an environment with a certain gravity.

In this case, in addition to the aerospace mothership, heavy transport ship, and warship, Li Qingsong decided to build a type of spacecraft that had never been built before.

A life-support spacecraft with artificial gravity!
Things like generating or offsetting gravity out of thin air are out of reach for Li Qingsong now.

Li Qingsong guessed that it would require a technological level at least higher than that of the intelligent mechanical disaster to achieve.

However, Li Qingsong has another clever way to achieve this.

That is centrifugal force, which relies on the outward centrifugal force of rotation to create an effect equivalent to gravity.

The appearance of this spacecraft then becomes obvious.

It must be in the shape of a ring or a drum, because only in this way can it maintain its rotation and generate gravity.

After comprehensive consideration, Li Qingsong finally chose the drum shape. The reason is simple: the drum shape maximizes space and area utilization.

So, like other types of spacecraft, the first prototype of this drum-shaped spacecraft was soon produced.

What appeared in front of Li Qingsong at this moment was a huge hollow cylindrical spaceship.

It has a huge main shaft running through the center of the cylinder, and numerous steel structures extend from the main shaft to fix the roller-like structure on the outside.

The drum-like structure rotates slowly at a fixed speed, so there is gravity inside the drum-like structure.

Such a roller-shaped spacecraft is 10 kilometers long and 600 meters in diameter.

Thus, the interior of a single drum-shaped spacecraft has an area of approximately 19 square kilometers. After deducting the necessary land for facilities, there is still about 15 square kilometers of usable area.

Here, Li Qingsong did not consider factors such as aesthetics and livability. He completely built living facilities on the available area, such as dormitories, canteens, etc., and they all had many floors.

In this way, under extreme circumstances, this 15 square kilometers of area can accommodate about 1000 million clones.

10 billion clones, 100 such roller-shaped spacecraft will be enough.

However, considering the large amount of scientific research facilities that needed to be built, as well as transportation issues—after all, these clones also needed to be frequently moved, and even a large amount of transportation between different spacecraft was needed—Li Qingsong obviously couldn't go so far. Ultimately, Li Qingsong decided to build 1000 of these roller-shaped habitable spacecraft. On average, one roller-shaped spacecraft would be responsible for the work and living needs of approximately 100 million clones.

In addition to the roller-shaped spaceship for the clones to live in, the living and working needs of the blueprint people also need to be addressed.

At this moment, after all these years of development, the number of Blueprint people has increased to about 200 million.

Blueprint humans were different from clones. If they were allowed to live like clones, they would be lucky if they didn't go crazy, let alone produce any scientific value for Li Qingsong.

There was no other way. In order to better extract value from them, Li Qingsong could only build more roller-shaped spaceships. At the same time, he reduced the population density of a single roller-shaped spaceship. In addition to the necessary industrial, living, and scientific research facilities, he wasted a lot of area on growing plants, raising wild animals, and even building completely useless things such as rockery and rivers.

In this case, a single roller-shaped spaceship could only support 20 Blueprinters. Two hundred million Blueprinters would require the construction of another 1000 roller-shaped spaceships.

So, 2000 large roller ships, 65 warships, 500 million unmanned warships, 500 aerospace carriers, 1000 heavy transport ships, and other types of ships...

All in all, the total number of spaceships Li Qingsong needs to produce reaches about 570 million!

Including various consumption and spare supplies during the voyage, the total mass of the entire fleet will reach more than 4000 billion tons!
One thing that is very obvious is that for every ton of spacecraft or material mass produced, Li Qingsong needs to consume dozens of times more resources to reproduce it.

By this calculation, the total mass of materials that Li Qingsong needs to mine, smelt and transport during the entire production process is at least more than 20 trillion tons.

A mass of more than 20 trillion tons!

If this much mass were all water and were spread across the Earth, it would create more than 300 Qinghai Lakes!
Mobilize the mass of more than 300 Qinghai Lakes to produce millions of spacecraft equivalent to the mass of six Qinghai Lakes, and then propel them to travel over long distances of tens of trillions of kilometers, from one star system to another.

Such a huge project, such a great voyage, just thinking about it would make the Bluetook civilization, even at its peak, feel daunted and fearful.

But at this moment, the maximum number of consciousness connections is only 10 billion, which is only one percent of the population of the Bluetook people in their heyday, but Li Qingsong is full of confidence.

Under the unified mobilization of Li Qingsong, the unified management and coordination of the Jade Emperor, and the direct construction of AI in various industries such as Shengong, Shennong, Dianmu, Luban, and Transportation, an unprecedented large-scale construction project affecting the entire solar system has truly begun.

There are countless mines on many planets, and many giant machines roar all day long. A large amount of primary minerals enter the factories that roar all day long, producing countless metals, which are either processed on site or sent to other planets via space elevators and heavy cargo ships.

Space bases appeared in orbit around numerous planets, and countless spacecraft arrived and departed. Giant aerospace carriers gradually took shape in space, and within these empty "cages," like fruit trees bearing fruit, supply boxes, life support pods, and so on quickly emerged.

Preparations for interstellar voyages were in full swing, occupying more than 99% of Li Qingsong's energy.

Li Qingsong put a considerable portion of his remaining energy into another matter.

"The difficulty of restoring the Earth's ecosystem is beyond my expectations. It seems I need to think of a solution."
