Homo sapiens.

Although these bereaved dogs are still closely monitored by the Space Investigation Department.

Just now.

The two Homo sapiens expedition fleets that have been upgraded have finally reached the edge of the six-claw giant nebula.

Zheng Bai, the commander of the Second Expeditionary Fleet, quickly dispatched half of the warships. With 5 warships as a team, they were responsible for chasing and killing the spaceships that escaped from the six-claw superstar.

On the other hand, the Third Expeditionary Fleet crossed the six-claw giant nebula and headed towards the main force of the previous six-claw fleeing fleet at full speed.

In fact, those six-clawed people who fled at this time basically could not escape the pursuit of Homo sapiens.

After all, the six-claw man's space battleship or spaceship can only reach 0.6% of the speed of light at the fastest speed; while the spaceship or space battleship of Homo sapiens, the fastest speed at present is already approaching 7% of the speed of light.

The speed gap between the two has expanded to about 11 times.

In other words, even if the escaped spaceships of the six-clawed people have been flying for more than ten years, it only takes a year or two for the warships of the Homo sapiens expedition to catch up with them.

The difference in speed is doomed to the demise of the Six Claws.

Homo sapiens, however, will not show mercy. The highest respect for a civilization is to drive it to extinction.

However, at this time, the Second Expeditionary Fleet, which had just arrived at the edge of the giant nebula, only had 182 battleships left after dividing half of the battleships.

At this time, the remaining six-clawed people hidden inside the giant nebula finally couldn't hold back the hatred and killing intent in their hearts.

Hundreds of small suicide spaceships sped out from the wreckage of several nearby planets, rushing towards the Second Expeditionary Fleet frantically.

Zheng Bai's synchronous robot is sitting in danger. In fact, after he reaches the vicinity of the giant nebula, he will notice the existence of remnants of six-clawed people inside the giant nebula.

After more than ten years of desperate development, coupled with human cloning and robot technology, these six-clawed people not only raised the population to several million with the help of some planetary debris and nebula materials, but also rebuilt a fleet of more than 700 warships. fleet.

If it weren't for the fact that the giant nebula is not stable at this time, plus a large part of the infrastructure has been destroyed, and the lack of various technical personnel, they can actually develop even stronger.

It's a pity that these six-clawed people did not expect that the enemy would come so quickly.

These six-clawed people have given up their escape and are ready to fight to the death with the Homo sapiens expeditionary force.

Facing the small suicide spaceship rushing madly, Zheng Bai did not panic at all. He calmly ordered: "Use the particle cannon to annihilate all invading enemies!"

"Roger that!"

Of course, the particle cannons on those Qinglong III space battleships are not as good as the Neptune particle cannons, but their destructive power is also very terrifying.

Masses of twin-neutron shells were accelerated to nearly the speed of light and sprayed towards the six-clawed suicide ships.

Just flew out less than 10 minutes.

The overwhelming double neutron shells blasted hundreds of suicide spaceships into the void.

Through the detectors, the surviving six-clawed people who monitored this scene were completely desperate at this time.

Many Six Claws couldn't accept this reality and chose to commit suicide.

There were also quite a few Six Claws who went completely crazy, launching all kinds of weapons at once, and then took the initiative to attack with the battleship, planning to fight to the death.

There are also some six-clawed people hiding in the wreckage of the planet or the wreckage of the space city, planning to detonate the hydrogen bomb in it when the expeditionary force lands, and perish together with the landing battleship.

As for surrender, these six-clawed people knew very well that even if they surrendered, the fate would not be much better, and they might as well fight to the death.

It's a pity that their desperate efforts have no effect.

The particle cannon is too lethal to ordinary space battleships and spaceships, even if it is equipped with a magnetic field offset shield, it is useless. Those double neutron shells can tear the magnetic field offset shield in an instant, and the battleship and spaceship Crushed into scrap iron.

less than a week.

About 90% of the warships and spaceships of the Six-claw Remnant faction have been wiped out, and only a small part is left huddled in the core area of ​​the giant nebula, using the debris of the planet as a shelter, temporarily lingering.

And the Homo sapiens expeditionary force that cleared the outer area of ​​the giant nebula did not immediately wipe out the remnants of the six-clawed soldiers.

Zheng Baike knew very well that in order to retaliate against the Sapiens Expeditionary Force, those six-clawed people hid a large number of nuclear bombs and a large number of suicide small spaceships among the asteroids inside the nebula.

Now rushing in directly, even if these six-claw remnants can be eliminated, there will be some losses.

Although the particle cannon can be used to continuously fire, there are serious safety hazards after the particle cannon is used.

Therefore, when annihilating most of the remaining warships of the Six Claws faction, the expeditionary force chose a special position and fired the double neutron shells in the same direction as much as possible to avoid random spraying.

If the dual-neutron shells are sprayed indiscriminately, maybe one day these dual-neutron shells will hit Homo sapiens' own spacecraft or facilities.

Zheng Bai didn't want to abuse the particle cannon, he chose another plan, that is machine sea tactics.

A large number of dense gamma rays swept past a large natural satellite wreckage floating in the periphery.

Those hidden nuclear bombs or suicide spacecraft were annihilated on the spot before they could be activated.

Then a dozen missiles plunged into the surface of the planet's wreckage.

Those missiles are not equipped with nuclear warheads or other warheads, but nano-robots made of a large amount of living metal.

As a large number of nano-robots spread, using the long-distance power transmission system inside the battleship, these nano-robots frantically devoured all the matter of the planet's wreckage.

The six-clawed people hiding inside the wreckage of the planet saw that the aliens did not land at all, and they were very anxious and disturbed.

However, they have no way out.

As the nano-robots covered the entire planet's wreckage, the six-clawed men hidden in it and the traps they prepared disappeared directly.

The same situation is continuously happening in the periphery of the giant nebula.

The wreckage of planets, space cities and space battleships were destroyed one after another, and the newly formed asteroids were frantically swallowed by nano-robots.

The dying struggle of the remnants of the Six Claws had no effect.

Even if some of the six-clawed people detonate the nuclear bomb after realizing the problem, they can only destroy some of the nano-robots.

And nano-robots can replicate themselves. If the nano-robots in this giant nebula cannot be completely destroyed in an instant, then the nano-robots can continue to snowball, and then forcefully consume the enemy to death.

The remnants of the six-clawed people who almost detonated hundreds of thousands of hydrogen bombs destroyed only a part of the nano-robots that invaded the core area of ​​the giant nebula.

And the nano-robots in the periphery are already overwhelming, and they are not destroyed at all.

In less than three months, the entire interior of the giant nebula was completely cleaned up.

So far, the Homo sapiens expeditionary force’s work in the giant nebula has completed the first stage, and started to enter the second stage.

Chapter 685 Artificial Earth

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.
