It's a huge city, and it's a very unique city.

Most uniquely, the city has a large number of public spaces and buildings are spaced far apart. Also, this is a three-dimensional city, but it is not the same as the cities that Chu Tianjiang saw on the United Continent, that is, it is not through three-dimensional to increase the capacity of the city, but to improve the structure of the city. What's more, there are definitely not as many inhabitants in this city as there are in human cities.

Obviously, in the civilization created by the invaders, each individual needs enough space and enough resources.

According to the information provided by Ivey, Chu Tianjiang found the building, a ring-shaped structure to be exact, erected on the ground by some thick pillars, and all sides of the building were transparent, even the frame that carried the weight was translucent. Underneath the building, the ecological environment remains intact, but all of them have been destroyed, or the natural creatures have died. The building is floating in the air, and there is no layering, the whole building is a whole, a whole space made of transparent objects.

Obviously, the way of life of the invaders is very different from that of humans.

This is also understandable, as invaders are typical sea creatures and therefore have a stronger sense of three-dimensional space, while humans are typically terrestrial creatures and are more familiar with the plane. Even after arriving on land, the invaders maintained the most primitive way of life. It's like more than 10,000 years ago, after humans built a huge space city, they still haven't changed their living habits on the ground.

This building is the center of the invaders' domination on the home planet.

In a sense, in the social structure of the invaders, there is no relationship between "domination" and "rule", and their social form is completely different from that of human beings.

That is, in the world of invaders, each individual has the value of its existence from the moment of birth.

In a sense, this is also an inevitable change in the evolution of intelligent civilization from natural evolution to self-evolution, and it is also a change that must occur in response to higher-level science and technology. Only this social form can ensure that the social situation of the invaders is sufficiently stable.

After entering the stage of self-evolution, the first thing the invaders do is not to develop technology, but to build a new social order on the basis of existing technology.

Among them, the most important is the establishment of a racial gene information database.

This repository of information, which contains the genetic characteristics of all individuals of the invader, can be said to be the social cornerstone of the invader.

It is through this gene pool that the invaders begin to create entirely new offspring according to the needs of the social position, thus ensuring the reproduction and development of the race.

Of course, this is just the basics, not the whole story.

After the establishment of the genetic information bank, each individual of the invader was included in the "genetic supervision system", and a set of equipment was installed in the body to monitor genetic changes in real time. With this device, the genetic mutations that occur in each individual are recorded and analyzed by scientists. If it is a useful genetic mutation, it is stored in a gene database and then manifested in a certain offspring.

Obviously, this is the most important work of the self-evolution stage.

By taking advantage of these genetic mutations produced by environmental influences, especially beneficial mutations, the invaders are able to continuously improve themselves in evolution.

Of course, these also revolutionized the way invaders reproduced.

Although some of the primitive instinctive behaviors related to reproduction have not disappeared, for the vast majority of individuals, such behaviors have become a pure spiritual enjoyment, and are not directly related to gender. In fact, in the case where all offspring are born by genetic splicing, "gender" has disappeared from the basic moral concept of the invader, and it has no effect on reproduction.

More importantly, this changes the basic socio-ethical structure of the invaders.

Before entering the stage of self-evolution, the invaders were very similar to human beings, that is, each individual had a father and a mother, and from this there was a blood relationship, and the ethics of the whole society were based on this blood relationship. The new way of reproduction has made blood relations an ornament, and it is not so reliable, because the genes that individuals possess do not come from two parents, but may be one or countless parents. Without blood relations, there is no place for ethical and moral concepts based on blood relations.

To the invaders, each individual is a single and pure being, and the idea is of the whole race, not of some other individual.

All in all, after entering the stage of self-evolution, the social structure of the invaders has become very different from that of humans.

The key is that the gene information bank stores all the characteristic genes of the individual.

According to Ivey, there are a total of four genetic databases, that is, one in each of the four micro-universes that the invaders have fully controlled.

In this repository of information, there is the past of the invaders, and it also symbolizes the future of the invaders.

As long as the genetic information base still exists, as long as the information inside still exists, no matter what has become of the invader's civilization, it can be restored.

To put it bluntly, using the information in the genetic database, the invaders are able to produce enough offspring.

What Ivy had to do was to ask Chu Tianjiang to find the genetic information database and obtain the information stored in it.

Entering the interior of the building, Chu Tianjiang let a part of the mass energy body spread naturally.

While not all invaders possess a body made of mass, those in power among the invaders, those who are destined to be leaders before birth, are able to control the body and preserve the most important information through it.

In other words, all the information in the gene database is stored in the plastosome.

As such, only individuals who can control the mass can read this information and use it to reproduce.

Although Chu Tianjiang was not a member of the invaders, he was a qualitative person, and he was able to control the qualitative body.

According to what Ivy said, Chu Tianjiang dispersed a part of the mass energy body, and then waited patiently. When that wonderful feeling arose, Chu Tianjiang began to gather those scattered mass energy bodies, and organized the information that the mass energy bodies had captured from the surrounding environment.

The invaders have given up on this place, and naturally they have given up on this genetic database.

It's just that information is eternal, but it has been transformed into a different form, and the mass body can restore the information in these forms to its original state.

When this information was organized, Chu Tianjiang saw an amazing picture.

That was thousands of years ago, maybe 5,000 years. At that time, the invaders' home planet was still thriving, with tens of billions of individuals living there, and tens of millions of individuals in the city alone. Of course, most individuals live in the ocean, and they are more familiar with the ocean and prefer it. The catastrophe came very suddenly, starting with the collapse of the inner core of the star, which directly caused the magnetic field generated by the inner core to disappear. The result was catastrophic, with the star storm unleashed by the main star, ruthlessly taking away the atmosphere and raising the surface temperature of the star, causing the seawater to evaporate and eventually dissipate into outer space. It's just that when the disaster came, there was no social ****, and all individuals calmly accepted the disaster. No individual fled, and no individual struggled to survive. It seems that for all individuals of the invaders, including those who are in a dominant position, it is their destiny and their last value to calmly embrace the destruction and death brought about by the disaster. Disaster came, but destruction was a relatively long process. It took hundreds of years, and hundreds of years after the invaders, for the entire planet to be completely destroyed, and the last invader to die.

Throughout, not a single individual fled the impending destruction of the astral body.

With that, the glorious civilization created by the invaders.

Chu Tianjiang was very surprised, and he was a little puzzled. Of course, he is human and has human cognition, so he cannot understand the actions of the intruder.

This collective self-destruction cannot be understood by human cognition by anyone else.

It is important to know that the collapse of the inner core of the star is not a natural phenomenon, but the work of an intruder.

In other words, the invaders destroyed their home planet with their own hands, destroyed tens of billions of individuals, and led to the complete extinction of a glorious civilization.

It's hard to imagine, if not at all.

In Chu Tianjiang's opinion, it must have been the invaders who gave up this micro-universe and went to other micro-universes.

The problem is, it doesn't make sense either.

According to Feister's reasoning, all micro-universes come from one creator, so even if the invaders escape to other micro-universes, as long as they have strong scientific and technological strength, they will still suffer from extinction at the moment of the creator's arrival, and it is impossible to escape.

Could it be that the invaders have also abandoned other micro-universes?

If that were the case, the invaders would be extinct, at least at the level of the microuniverse.

No, it's certainly not true!

No matter what level of civilization the invaders reach, as a civilization, the most important thing is to survive and reproduce, and no civilization will destroy itself.

This is definitely not self-destruction, the intruder is doing it for another purpose.

A more important purpose, and one that is directly related to the preservation of civilization, or the purpose of which is to preserve the civilization of the invaders.

Obviously, the invaders had done a lot of things, and there were many things that Chu Tianjiang didn't know about at all.

With this question, Chu Tianjiang left this destroyed star.

Ivey was right, he would return to the wormhole space, because only Ivey could explain the question.
