Homo sapiens.

The Hexapod Nebula.

It has been 10 Earth years since the Homo sapiens expedition conquered here.

During this period, the pursuit team of the expeditionary fleet kept chasing and killing the escaped spaceship of the Six-clawed people, and finally wiped out the remaining Six-clawed people 5 years ago.

At this point, the Six Claws were completely wiped out.

The war between first-level civilizations is so cruel. In order to avoid leaving hidden dangers, after defeating a civilization, they often use the method of killing the defeated civilization.

If the Six Claws defeated the Homo sapiens company, the fate of human beings would also be a dead end.

The strategic analysis office of Homo sapiens has conducted a lot of analysis on the cosmic social operation mode among the first-level civilizations.

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

The reason for such a conclusion.

The reason is very simple. For a first-level civilization, the speed of light bottleneck is an unavoidable big problem, and under the premise that the speed of light bottleneck exists, colonizing other planetary systems can only be carried out by in-situ reproduction.

So why colonize other planetary systems?
The answer is for safety and race continuation.

Just like the six-clawed people, if they did not self-castrate themselves, but concentrated on colonizing the solar system, they would have been able to reach the solar system thousands of years ago.

Obviously, the Six Claws missed an opportunity to change their fate against the sky.

Naturally Homo sapiens now can't follow the old path of the six-clawed man and grow up in the solar system, that's courting death.

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

One of the most critical plans is the artificial earth plan.

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

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

Among them, the task of the giant star colonization branch is to use the resources of the giant nebula to build an artificial earth with all its strength.

Building an earth is actually not difficult for Homo sapiens companies at this stage. The key difficulty is mainly in resources.

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

Obviously, the artificial earth project is in the solar system, and it is doomed to be impossible to implement in a short time.

On the side of the giant nebula, the gravitational issue of the planetary system can be ignored, and its own resources are more.

After the disintegration of the giant star, plus the attached natural planet, the total amount of matter it possesses is roughly equivalent to 1432 earths.

Due to the disintegration of the giant star, these substances formed a large-scale nebula and densely packed asteroids, plus dozens of relatively large debris from the core of the giant star, which can actually be mined and utilized.

If mining is not done quickly, in about four to five hundred years, these wreckages will recondense into a brand new giant gaseous planet.

For Homo sapiens, which worked so hard to blow up the superstar, it would be a great disadvantage to reunite the superstar nebula.

Therefore, the superstar colony branch must complete the division and movement of the entire superstar nebula within the window period of 400 years.

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

These substances are enough to build thousands of artificial earths.

However, the giant star colonization branch did not use all the resources to build the artificial earth, and the artificial earth is not simply a pile of matter.

The 15 artificial earths under construction at this time are floating on the periphery of the giant nebula.

A large number of unmanned spaceships with a length of tens of kilometers transported the mined materials from the core area of ​​the giant nebula bit by bit.

The nanorobots mine the remnants of giant stars very quickly. If they go all out, they can mine the material equivalent to 2.4 moons every day.

On artificial earth one.

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

Through the huge floor-to-ceiling windows, you can see a huge dim silhouette in the void in the distance.

In a giant nebula without stars, the internal light is very weak at this time, and only the remains of the giant star core, because it is a heavy element core, will produce nuclear fission and nuclear decay, so it will emit a dark red faint light, which is similar to the color of magma .

Therefore giant nebulae are very dark.

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

Deputy Director Andrew floated in: "Director, Artificial Earth No. [-] is now ready to enter the stage of construction."

"Well, I know." Zheng Bai was very clear about this: "Then allocate the materials as much as possible to the No. [-] artificial earth, is there no problem?"

"no problem."

As for how to build an artificial earth, the Engineering Division naturally has a set of special plans.

Regardless of the fact that nanorobots can mine many materials from the moon in a day, transportation, deep processing, and 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 certainly does not have so many space ports and engineering projects.

So from the very beginning, the Engineering Business Division simultaneously launched a construction plan for 15 artificial earths.

Now the artificial earth No. [-] has completed the supporting spaceport, and a large part of the outer frame has also been completed.

This is the time to concentrate resources and complete the construction of the No. [-] artificial earth.

The radius of the No. [-] artificial earth is much larger than that of the earth, but the total amount of material used is almost the same as that of the earth.

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

For example, the ongoing work at this time is to cast a star core. The raw material is the remains of the giant star core. Filling those heavy elements into the star core area of ​​the artificial earth can cast a core that is about the same size as the natural earth star core. .

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

Therefore, the artificial earth does not have a mantle.

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 a planetary thruster.

However, the eight planetary thrusters have not been built yet, and it is time to build the planetary thrusters after the star core casting is completed so that the artificial earth has a stable center of mass.

And these planetary thrusters are very huge, and their length extends directly from the star core to the dome on the surface, with a length of about 6000 kilometers and a radius of 300 kilometers.
