Now that the earth has been repaired and the biosphere is being rebuilt, the Chinese civilization has accumulated a lot of experience in planetary transformation in the process of repairing the earth.

Now, the Chinese civilization has been able to transform ordinary rocky planets into living planets through orbit adjustment, atmosphere formation, and crustal material structure adjustment.

It takes a long time to transform the planet, coupled with the sparse population of the Chinese civilization, there is no longer much need for the living planet, and in the next few hundred or thousand, the solar system will be enough to carry the growing population of the Chinese civilization.

What Chinese civilization needs now is a large amount of energy, as well as rare substances that are indispensable for the manufacture of high-tech items.

The Chinese civilization can use the material conversion device to directly convert matter into energy, and then make a very dense and stable energy crystal.

Under specific excitation, these energy crystals can continuously and stably output a large amount of energy, which is used for all ultra-high-power devices, and can also be easily converted into a large number of basic materials, which are the general equivalents between primary civilizations in the interstellar world, called cosmic source crystals.

All the more advanced primary civilizations will convert energy into source crystals for use, but they have limited ways to obtain energy, only conventional methods such as nuclear fusion, so most of their source crystals are in short supply.

And with the material conversion device, the Chinese civilization can unlimitedly convert all matter into energy, which is equivalent to having a money printing machine, as long as it is driven into a material-rich galaxy, the energy will continue to draw out money, which is simply an artifact for the primary civilization, and the intermediate civilization actually does not need the low-level energy of the source crystal.

The material transformation device involves the change of basic physical rules, and is the only creation of intermediate civilization technology in the Chinese civilization, and the Academy of Sciences has not been able to crack its technology so far.

Liu Xingchen thinks that they don't even have a solid foundation, and it's still too early to contact this, if it weren't for the real need of the Chinese civilization, he would have to take back this kind of thing that is too advanced, but it still restricts their use, and they are not allowed to transform high-grade materials that cannot be manufactured today, but can only transform a small part of them for research.

Those rare materials, because the Kashiva civilization had already looted tens of thousands of years ago, will not be left in the entire solar system now, unless the entire galaxy is turned over, and some can be found.

In fact, those rare substances can also be synthesized, but the consumption is too large and the efficiency is too low, so it is better to collect them in nature.

Therefore, the Chinese civilization decided to expand around, in addition to looking for galaxies suitable for development, it is also collecting those rare materials that are used to make high-tech items.

Liu Xingchen didn't know much about the galaxies around the solar system, before this time of travel, when he was strong enough to return to Earth, the solar system was within a few hundred light years, all of which were hit by the rule weapons of that intermediate civilization, and turned into nothingness.

At that time, Liu Xingchen only learned about the cause of the destruction of the earth, so he didn't pay attention to anything else, so the Chinese civilization had to re-examine the situation of the nearby galaxies.

The solar system and its surrounding galaxies are the birthplace of Chinese civilization and the hinterland of the future territory, and they cannot transform too much matter, as for those distant unowned galaxies, of course, they are transformed ...... at will.

In the future, this caused rumors that the Chinese civilization was more ferocious than the Zerg, and the Zerg was at least a barren country after that, and the Chinese civilization was a void after that.

Of course, these are all rumors, in fact, the Chinese civilization only transformed some barren galaxies that are far away from the solar system and have no life into source crystals, and after storing enough source crystals, they will no longer be so crazy.

The Chinese civilization's act of emptying the entire galaxy happened to be discovered by people from certain civilizations, and it was obviously their propaganda with ulterior motives.

After building a spaceship that could travel extremely close to the speed of light, the Chinese civilization sent a construction spaceship to each of the surrounding galaxies, and the galaxies where the original three living planets were located also re-dispatched spaceships.

So the spacecraft that arrived at the Purple Microstar was several years earlier than expected, and the construction spacecraft established a stargate in that galaxy, and at the same time cleared a place on the Purple Microstar and built a temporary base.

Before, the Chinese civilization was busy preparing to fight with the Kashiwa civilization fleet, except for sending people to investigate at the beginning, it has not paid too much attention to Ziweixing, and now that the war has come to an end, some people have proposed to open up a second base of Chinese civilization in Ziweixing.

After investigation, the Chinese civilization has the details of that galaxy:

The galaxy where Ziwei is located, far from the Kashiva civilization, has two stars in the galaxy, one of which is 1.3 times the mass of the Sun and is in the main-sequence stage, and the other is a white dwarf with a mass of 0.8 times that of the Sun.

The two stars orbit each other around the mass core of the two lines, with a period of 666 years, and the violet microstar is located in the habitable zone close to the mass core, with an average radius of 6,130 kilometers, which is slightly smaller than that of the Earth.

When each sidereal cycle approaches the white dwarf, the violet microstar will be affected by its gravitational tides, and the ocean on the surface will set off huge waves thousands of meters high, submerging most of the landmass, and it will last for about ten years, which may be one of the reasons why there is no civilization on the violet microstar.

Except for Ziwei Star, there are no other planets in the entire galaxy, only numerous asteroid belts, as if in the distant past, a tragic war broke out there, and the other planets were shattered, because the time was too long, and the explorers of the Chinese civilization did not find any traces.

In this case, the galaxy where Ziweixing is located is obviously not suitable as the second branch of Chinese civilization, but due to its unique celestial environment, it is still a natural living planet, and in the future, it will become the hinterland of Chinese civilization.

The Purple Microstar will be built into a tourist planet with unique scenery, while developing animal husbandry and marine aquaculture.

In order to look concise, the Chinese civilization cleaned up all the asteroid belts in the galaxy and converted them into cosmic source crystals, and by the way, only a little rare material was scavenged, and it was obvious that this place had already been scavenged.

Next, the Chinese civilization investigated the surrounding galaxies, in addition to a few galaxies that were patronized by the Kasiwa civilization, and there were not many rare materials left, they also found several galaxies with relatively rich resources.

At the same time, the Chinese civilization has also found a galaxy that can be used as a second base, that galaxy is very stable and rich in materials, with eleven rocky planets that can be transformed into living planets, and three huge gas planets rich in rare materials, and the surrounding galaxies are also relatively dense, in the core of this star field, the Chinese civilization named this galaxy Yanhuang Galaxy.

The Yanhuang Galaxy is 9.8 light-years away from the solar system, located in the rear of the war with the Kashiva civilization, and if the transit station is within two jumps of the flagship, it can rush to the rescue in time even if the stargate is occupied, which is a good base.

After the war with the Kashiwa civilization is over, the Huaxia civilization is ready to gradually shift its focus to the Yanhuang galaxy, building it into a galaxy like the capital star, and better radiating its power to the entire star region.
