Xinghai: Get the mechanical girl race at the beginning!

And about how to remodel the dome star next.

This is a bit of a science.

The dome star has a distance of 210 million kilometers.

The distance from Don Juan's base is about 4.9 billion kilometers.

Strictly speaking, the location of Don Juan's base is within the range of the 117 galaxy shrouded by the stellar wind, slightly outward.

Don Juan's base is about 3.2 billion kilometers away from the Star Gate.

The star gate is about 8.3 billion kilometers away from the star at the center of the galaxy.

If Don Juan wants to occupy the entire 117 galaxies, he must first grasp the complete situation in the 117 galaxies.

It is also necessary to expel a small pioneer force of the Yata Empire that is still roaming the 117 galaxy.

Before he defeated the Yata Empire's civilian combined fleet, such a big battle, it is impossible for the Yata Empire to be without action after that.

Don Juan had to organize defensive measures as soon as possible.

While organizing the defense measures, he also had to establish a new base in the Dome Star.

And the previous base, Don Juan changed his mind and did not plan to migrate over, but directly established a new base in the Dome Star as his home star base.

After all, the Dome Star has complete energy shield protection, and this alone, the protection level is countless times stronger than the previous base.

The previous base would be used by Don Juan as an outpost near the Star Gate.

It will be built as a defensive belt by Don Juan.

The star gate at the edge of the galaxy is not static to stay put.

Rather, like other celestial bodies in the galaxy, it has a fixed orbit around the galaxy.

And if a new main base is to be built in the Dome Star, where will the large amount of minerals used for construction come from?

The various mineral resources left over from the dome star are still abundant, but they cannot withstand too large-scale mining.

Don Juan set his sights on the planet closest to the star.

The star of Galaxy 117 is a red giant that has entered its old age.

The diameter reached a terrifying 230 million kilometers.

When Don Juan first arrived at this galaxy through the stargate, he observed that there were three intact planets in this galaxy.

It's not too far from the star.

The first planet that Don Juan arrived on was the gas giant that had leapt into the space of Gauvia and mysteriously disappeared.

Before the gas giant disappeared, it was 700 million kilometers away from the star.

The second planet is the dome star, which is about 210 million kilometers away from the star.

The third planet, which is also the closest planet to the star, is only less than 40 million kilometers away, and has turned into a dead planet at this moment.

According to the research of the technical humanoid girl, before the star expands into a red giant, it should be about 1.2 million kilometers in diameter, which is a star slightly smaller than the sun.

At that time, there should be several planets in front of the dead planet, but these planets were completely swallowed by the stars that expanded into red giants.

When there really is not even slag left.

The dead planet closest to the star became the target of Don Juan's mining of various minerals.

The Dead Planet, about 20,000 kilometers in diameter, has three dwarf planets with diameters of 900 km, 1,700 km, and 2,400 km as moons.

Don Juan sent a warship to investigate.

After initial exploration, it was determined that these planets have relatively rich mineral resources inside.

Withstands large-scale mining and use.

The dead star is only 170 million kilometers away from the dome star.

Very close.

As for how to build, among the ancient ruins throughout the Dome Star, Don Juan obtained more than five hundred complete subspace devices.

120,000 mechanical guards without inertial engines that were mothballed, preserved in good means, and still usable, plus more than 10,000 mechanical guards who were originally outside the Dome Star shield and were originally on the low-Earth orbit space-based defense platform.

and the thirteen thousand mechanical guards previously acquired by Don Juan.

Don Juan's mechanical guards numbered 143,000.

Of the 143,000 mechanical guards, 13,000 were originally in the original base, and Don Juan decided to distribute another 30,000 to the original base.

Leave 100,000 mechanical guards as the periphery of the dome star to protect the defense belt of the newly built low-Earth orbit space-based platform.

There are three hundred and seven automated mechanical cores and five automated warship production cores.

The various mineral resources stored inside the dead planet and its three moons, coal, iron, copper, aluminum, lead, tungsten, gold, rare earths, etc., add up to more than three trillion tons.

Among them, coal reserves alone account for 30%, followed by iron, aluminum and tungsten.

In addition, the three satellites also have helium with a total reserve of more than three million tons, which can be used for fusion.

The largest number of coal minerals is not useless, although this interstellar era has long eliminated the backward situation of coal power, but other industries also need to use a large amount of coal.

Carbon is used for artificial conversion of carbon into graphene, electrodes, carbon fibers, etc.

If Don Juan turns the three hundred and seven automated mechanical cores he has on hand into automated heavy metal mining, refining furnace factories and various large-scale integrated industrial plants, it will take more than 260 years to completely hollow out the planet.

But this is not the case, and Don Juan cannot build all the automated mechanical cores on the dead planet to mine.

Although the high temperature on the surface of the dead planet with an average temperature of more than 400 degrees is nothing.

Plants of all kinds of construction are fully capable of withstanding extremely high or low temperature changes.

But on the dead planet, some are also needed, but there are too many minerals that are not too important, and the more important mineral reserves are not too much.

Not to mention iron, a common heavy element, Don Juan also needs a large number of rare earth minerals.

So Don Juan needed to spread the factories evenly across the galaxy so that every resource could be averaged.

The asteroid belt near the dwarf galaxy of the original base has a variety of elements, and how to transport them after mining is a problem.

Don Juan's existing ships were combat ships and did not have special transport ships.

You have to buy large transport ship blueprints.

Thinking like this, Don Juan opened the system mall.

In the system mall, the [Seven-Yuan] level technology and battleship design drawings are unlocked and can be purchased.

But Don Juan just took a cursory glance, and then turned to open the [Jiuyao] level mall.

Without him, the various technologies of the [Seven Yuan] level, the design drawings of the battleship, are too expensive, and it takes millions of spiritual sources to start.

Now Don Juan only has more than 440,000 spiritual sources, which belongs to the wave of defraud.

As for the transport ships, the grade does not need to be too high, and the [Ten Capitals] class is too small to meet the requirements of Don Juan to carry in large quantities.

[Jiuyao] level will do.
