Six-clawed giant nebula.

It has been 10 Earth years since the Homo sapiens expeditionary force conquered this place.

During this period, the pursuit team of the expeditionary fleet kept chasing and killing the fleeing spacecraft of the Serapus, and finally completely wiped out the remaining Hexapus five years ago.

At this point, the Serapus were completely destroyed.

The war between first-level civilizations is so cruel, in order to avoid leaving hidden dangers, after defeating a civilization, it is often used to kill the defeated civilization in a way that treats the defeated civilization.

If the Hexapons defeated Homo sapiens, then the fate of humanity would also be a dead end.

The Strategic Analysis Office of Homo Sapiens has conducted a great deal of analysis of the mode of operation of the cosmic society between the first-level civilizations.

But no matter what kind of aliens they are, they will not easily coexist peacefully with other aliens.

The reason for this conclusion.

The reason is very simple, for first-level civilizations, the speed of light bottleneck is a big problem that is unavoidable, and under the premise of the existence of the speed of light bottleneck, colonization of other planetary systems can only be carried out by in-situ reproduction.

So why colonize other planetary systems?

The answer is for security and racial continuity.

For example, if they had not emasculated themselves and concentrated on colonizing the solar system, they would have arrived in the solar system thousands of years ago.

Obviously, the Hexapus missed an opportunity to change their lives.

Now the Homo sapiens company naturally can't follow the old path of the six-clawed people and sprout in the enclosure of the solar system, which is looking for death.

For the giant nebula, Homo sapiens headquarters has developed a series of development plans.

One of the most critical plans is the Artificial Earth Project.

This is also the reason why the expeditionary fleet was quickly reorganized into two parts after the end of the war of annihilation against the Hexapus.

Currently, the Expeditionary Force fleet has been reorganized into the "Superstar Defense Fleet" and the "Superstar Colony Branch".

Among them, the mission of the Giant Star Colony Branch is to use the resources of the Giant Nebula to build an artificial earth.

Building an earth is actually not difficult for Homo sapiens at this stage, and the key difficulty is mainly in resources.

In the solar system, although there are a lot of resources, there is another problem, that is, the gravitational stability of the galaxy must be considered.

Obviously, the artificial earth project is in the solar system, and it is destined to be impossible to operate in a short period of time.

On the side of the giant nebula, the gravitational force of the planetary system can be ignored, and there are more resources in itself.

After the disintegration, the total amount of matter possessed by the giant star, plus the attached natural planets, is roughly equivalent to 1,432 Earths.

Due to the disintegration of the giant star, these materials have formed a large range of nebulae at this time, as well as dense asteroids, plus dozens of relatively large debris split from the core of the giant star, which can actually be mined and utilized.

If we don't mine it now, in about four or five hundred years, these debris will recondense into a new giant gaseous planet.

For the company of Homo sapiens, which worked hard to blow up the superstar, it is very disadvantageous to let the superstar recondense again.

Therefore, the Giant Star Colony Branch must complete the division and movement of the entire Giant Nebula within a window of 400 years.

According to the plan, the giant nebula will be divided into tens, and the mass of each part will be about 143 Earths.

That's enough material to build thousands of artificial Earths.

However, the Superstar Colony Branch did not spend all of its resources on building artificial Earth, and artificial Earth was not simply a pile of materials.

At this time, 15 artificial Earths under construction are floating around the periphery of the giant nebula.

A large number of unmanned spacecraft with a length of tens of kilometers will transport the mined materials from the core area of the giant nebula little by little.

Nanobots can mine the remains of giant stars very quickly, and if they go all out, they can mine the equivalent of 2.4 moons of material every day.

One man-made Earth.

Zheng Bai, who has been transferred from the expeditionary force fleet to the head of the Colonial Engineering Division, is using a synchronous robot to float in his office.

Through the large floor-to-ceiling windows, a large dim silhouette can be seen in the void in the distance.

Giant nebulae without stars have a very faint light inside, and only the remains of the giant core, because it is a heavy elemental core, will produce nuclear fission and nuclear decay itself, so it will emit a faint light of dark red, which is similar to the color of magma.

Therefore the giant nebula is very faint.

At this time, Zheng Bai was browsing the progress of the construction of the No. 1 artificial earth.

Deputy Director Andrew floated in: "Director, at present, the No. 1 artificial earth can enter the stage of large-scale construction. ”

"yes, I know." Zheng Bai was clear about this: "Then deploy the materials to the side of the artificial earth No. 1 as much as possible, there is no problem, right?" ”

"No problem."

Naturally, the Engineering Division has a specific plan for how to build an artificial earth.

Don't look at the fact that nanorobots can mine materials for several months a day, but transportation and deep processing, as well as engineering construction, must not be concentrated on an artificial earth all at once.

Because doing so will lead to a decrease in transportation efficiency and construction efficiency, after all, the initial framework of an artificial earth must not have so many spaceports and engineering projects.

So from the very beginning, the Engineering Division started the construction plan of 15 artificial earths at the same time.

Now that the No. 1 artificial earth has completed the supporting spaceport, a large part of the outer frame has also been completed.

This is the time to concentrate resources and complete the construction of Artificial Earth One.

The radius of the artificial earth is much larger than that of the earth, but the total amount of material used is not much different from that of the earth.

The reason is that there are some differences between artificial and natural earth.

For example, the work being carried out at this time is to cast a star core, the raw material of which is the remains of the giant star core, and fill those heavy elements into the star core area of the artificial earth, and you can cast a core about the size of the natural earth core.

The structure that encloses the artificial core is a special material with a thickness of 300 kilometers, which can not only fix the inner core, but also use the core to generate artificial magnetic fields and generate geothermal power generation.

Therefore, there is no mantle in the artificial earth.

The area of the original mantle, in addition to the huge pillars, also serves as a storage area for various solid raw materials.

There are also eight planetary thrusters.

That's right, it's planetary thrusters.

However, these eight planetary thrusters have not yet been built at this time, and it is time to build planetary thrusters only after the star core is cast and the artificial earth has a stable center of mass.

These planetary thrusters are huge, extending directly from the core to the dome on the surface, with a length of about 6,000 kilometers and a radius of 300 kilometers.
