Most of the combined fleet of the Kashiwa civilization was wiped out, and some of them surrendered voluntarily, and they all became loyal soldiers of the Huaxia fleet after ideological transformation.

The battle ended without such a hitch, and the victory was even easier than the first time he faced Kasiva's vanguard fleet, thanks to the superiority in science and technology.

The gap between the levels of science and technology is enough for one side to be crushed, and there is no such thing as a cross-level battle in technology, a probe of a high-level civilization is enough to destroy all the fleets of a low-level civilization!

Now the Chinese civilization can also do this, with the improvement of various basic sciences, and unconventional material conversion devices, the Chinese Academy of Sciences has finally made a major breakthrough in materials science, which can manufacture a large number of materials with strong enough performance.

Coupled with the various third-level technologies that it had mastered, the Chinese civilization had created a real near-light speed spaceship, not relying on warp speed to sail, but the kind of spaceship that could approach the speed of light under conventional navigation.

The near-light speed spacecraft is a symbol of the three-level civilization, which not only has extremely high requirements for the materials of the hull, but also has extremely high requirements for the engine and process control technology.

After the creation of the light-speed spaceship, the Huaxia civilization has been reequipped, and the strength of the fleet has made a qualitative leap, with conventional near-light speed sailing, coupled with a variety of powerful third-level science and technology, so that the Huaxia fleet can already ignore the numerical advantage of the second-level civilization, and this time the Kashiva fleet is not very superior in numbers.

In order to prevent the Kashiva fleet from scattering and fleeing, the Huaxia fleet used warp speed to intercept them, and the high-strength materials that make up the hull could temporarily withstand the attack of the Kashiva fleet without opening the shield, and when they were close enough, they showed their hideous fangs and wiped out the little sheep of the Kashiva fleet.

With a complete third-level fleet, it does not mean that the Chinese civilization is already a third-level civilization, except for the strength of the war, other aspects are still far behind.

Regardless of population, territory, culture, and even heritage, the Chinese civilization is far from reaching the standard of a third-level civilization, and civilization includes more than just combat and technology.

However, the Chinese civilization now has a near-lightspeed spaceship, and is in a position where it can attack and retreat, and it is no longer afraid of the threat of force from most of the third-level civilizations, as well as all civilizations below the third-level level, and can slowly make up for the shortcomings.

After decades of development under the pressure of war, although the Chinese civilization has made rapid progress, everything is inclined to the war, but other aspects have not kept up with the pace of development.

Today, the Chinese civilization has a population of about 100 million, and about one-fifth of them are young children, and if you add those Kashiwa people who surrendered, there are about 150 million.

Of course, the vast majority of these Kashiva people will not enter the Chinese society, and they will have to serve in the fleet for the rest of their lives, because of the thorough ideological transformation, and the life in the fleet is also quite rich, and the Kashiwa people will not complain.

The earth was also restored a few years ago, and it was modified according to the original landform, but the land area reached 50%, the surface environment is beautiful, the climate is suitable, the light is sufficient, and it is extremely suitable for human growth.

Most of the people have moved to live on the ground, and many people, including the generation that grew up in space, have a feeling of coming home when they come to the ground, and many people have tears in their eyes.

When people work, they go back and forth between heaven and earth through space elevators and various aerospace vehicles, similar to commuting by bus thousands of years ago, and those who have a little savings will also buy personal aircraft, and for a time, Chinese civilization has some prosperity.

In Liu Xingchen's planning, the development of Chinese civilization should be multi-directional, and various mechanical civilizations and biological civilizations in the interstellar 、...... and the civilization in the direction of individual evolution, which will be included in the Chinese civilization system.

Although it is very difficult for such a comprehensive civilization to develop, it has great potential in the later period, and it can be said that only a civilization that involves many aspects and is proficient in all aspects can go further.

Liu Xingchen traveled through the starry sky, and saw a lot of civilizations that only developed but only developed in aspects, and developed rapidly in the early stage, and then stagnated after developing to a certain extent, and even entered a dead cycle of decline and development.

The key to breaking through the intermediate civilization is to fully understand the laws of the universe, and then make a breakthrough in a certain aspect, many third-level civilizations only discovered this at the end, but at that time their civilization system has been finalized, the overall thinking is rigid, and it is difficult to develop in an all-round way.

Of course, in the starry sky, there are so many development directions of various civilizations, all of which have their own characteristics, and some specific small directions, no one knows whether they are right or wrong, and they can only try them one by one, which is very energy-consuming.

Therefore, some senior interstellar civilizations will enslave many subsidiary civilizations, and while squeezing their surplus value, they also have the role of experimenting with various development paths and accumulating experience for the development of the main civilization.

The Kashiva civilization also enslaves many other civilizations, and the scientists in these civilizations do research in the direction they prescribe, and the other members do corresponding work according to their characteristics, such as entering the fleet as soldiers and even junior officers, and the good ones can even reach the middle level, and no matter how high they are, they can't.

This is also one of the reasons why some of those Kashiva fleets like to surrender after the defeat, most of the soldiers are subordinate civilizations, and there is not much sense of belonging to the main civilization.

In the starry sky, a civilization that has the ability to develop to the primary level on its own is of great value, and the higher the development potential of its civilization, the greater the value, and high-level civilizations like to accept some races with great potential as subsidiary civilizations.

Among the civilizations that have been accepted as subordinate civilizations, those who are in good condition will be treated better when they encounter more well-intentioned civilizations, and they may be out of control after being used; If you are unlucky, you will be enslaved forever, and you will even be used as cannon fodder, experimental materials, and transformed into biological weapons, and there is basically no future.

The primary civilization here refers to those civilizations that have just been promoted to the primary level, and as for those primitive civilizations that are still struggling on their home planet, they do not have these treatments, because the primitive civilizations have not shown any development potential, have no value, and do not get much benefit from them.

If the home planet of the primitive civilization is in the territory of other interstellar civilizations, it is possible to be cleaned up like weeds, and the best situation is to not be interfered with in the development, waiting for them to develop to the primary civilization and then harvest.

Due to the speed of light, the endless starry sky is like a boundless forest, and if a civilization is the first to develop in an area, it has the advantage of being at the top, oppressing the growth of the surrounding civilizations, robbing them of nutrients to feed themselves, and enslaving them to shelter themselves from the wind and rain.

Then grow up, and then pay attention to and rob the nutrients of the neighboring areas, and grow step by step, until it becomes an intermediate civilization that does not need these low-level nutrients.

Few civilizations can expand indefinitely, because they will always encounter civilizations that are equal to their own, or more powerful, and control a territory with each other to maintain balance.

If an area is raided by a civilization and then abandoned, or if the original powerful civilization suddenly disappears for some reason, and then no other civilization settles in or pays attention to it, the area is equivalent to a secondary forest, just waiting for a new civilization to appear and repeat the above process.

The starry sky where the earth is located, if it were not for the accident of birds and insects, would be a secondary forest that was not paid attention to, and the human beings on the earth would be the first civilization to develop, and those civilizations around it would be robbed and enslaved by him.

In fact, it is true, in the timeline before Liu Xingchen traveled, there was no accident of birds and insects, and the earth civilization was also the first to go to the starry sky, plundering the surrounding galaxies, and then adopted the Gadari civilization that had just come out of the home planet as the first subsidiary civilization, and then subdued the even more backward Gayrent.

At its most brilliant, the Earth civilization almost became a second-level civilization and stabilized its position in the starry sky, but unfortunately it was inadvertently erased by an intermediate civilization.

On the timeline of Liu Xingchen's arrival, for some reason, there was an accident of birds and insects, which almost wiped out the earth civilization, even if the birds and insects are now eliminated and science and technology are vigorously developed, the time for the Chinese civilization, which is the continuation of the earth civilization, to enter the starry sky has been delayed for nearly a thousand years.

However, even if it is a thousand years late, the two surrounding primitive civilizations have not entered the primary civilization, and they still can't escape the palm of Huaxia's hand.

I just don't know what their potential is, whether it's worth cultivating, and they can be treated preferentially as a subsidiary civilization, after all, they are all neighbors and develop together.
