The central galaxy of the Alliance of Intelligent Civilizations is extremely large, with an extremely large primary star and hundreds of substars that are also not small.

Although the central galaxy is directly controlled and managed by human civilization, the central galaxy does not belong to human civilization, but to the entire alliance of intelligent civilizations. In other words, the central galaxy is the administrative center of the Alliance of Intelligent Civilizations, as well as the military center of the Alliance of Intelligent Civilizations. In fact, in the new homeland, there is not a single star system that is completely owned by human civilization, and there is no direct control of a star system by humans.

Compared to the central galaxy, the breeding base of human civilization, that is, the only "home galaxy" that is directly controlled by human civilization and does not allow other intelligent civilizations to go to it, is much smaller. If the central galaxy is a nebula that houses a large number of stars, then the home galaxy is a standard star system, and a single star system, that is, it has only one star that is not too massive.

The home galaxy has many similarities with the solar system, but there are also big differences.

The biggest difference is that the home galaxy is not a naturally formed star system, that is, the home galaxy was not created by a creator and did not exist when the three-dimensional cosmic space was formed, but a star system created by humans after they came here.

In the home galaxy, all stars, including stars, are composed of star nuclei, and each star has a level of space debris in the fourth dimension, and it is composed of the star nucleus released by this level. Of course, there are only three stars in the home system, a star, a planet, and a moon. The four-dimensional cosmic space debris level in these three stars all comes from a four-dimensional cosmic space debris. The most special thing is that there are many layers of four-dimensional space debris in the outer part of the galaxy, to be precise, the entire galaxy is wrapped in the level of four-dimensional space debris. That is to say, when necessary, the entire galaxy can enter the space debris of the four-dimensional universe, and even be transferred to any place in the three-dimensional space through the space debris of the four-dimensional universe.

In other ways, the home galaxy is actually only displayed at the level of space debris in the four-dimensional universe, and does not completely belong to the three-dimensional space.

In other words, in the three-dimensional universe, the home galaxy does not exist.

Obviously, this arrangement is to ensure the safety of the home system. Even if it is attacked, it can transfer the entire home galaxy through the space debris of the four-dimensional universe, ensure that the home galaxy is not occupied and destroyed by the enemy, and protect everyone living in the home galaxy.

The people who live in the home system are the core members of human civilization.

On the only planet, the home planet, there is a natural environment similar to that of Earth, and the humans who live here maintain a relatively primitive lifestyle.

According to Zhang Xiaogang's arrangement, the legions that rotated to the homeland star to reproduce had to give up some personal abilities, return to the primitive state of life, and form a family with their spouses, reproduce in a normal way, and accompany the offspring, that is, the children to grow up for twenty years. It is only when the offspring have grown up that these Legion Commanders leave their home planet and travel to the Central System, where they can re-form their own legions. Their children, when they grow up, still need to undergo rigorous training and pass a series of assessments before they can become legion commanders. Of course, not all offspring can pass the assessment, so not all of them are legionnaires. Then the offspring who are not suitable to be the commander of the legion will be trained in other aspects and eventually become other roles.

There are only three people who know the exact location of the Dao Home Galaxy, namely Zhang Xiaogang, Chu Tianjiang and Luo Jinyong. Because Luo Jinyong has already fused with the stellar intelligent body, only Zhang Xiaogang and Chu Tianjiang can go to the home galaxy. Now, Chu Tianjiang has left the Alliance of Intelligent Civilizations with Ali, so only Zhang Xiaogang can go to the home galaxy. In order to ensure the safety of the home galaxy, to be precise, the safety of human civilization, Zhang Xiaogang did not even let Bei Ya know his exact location, let alone tell Bei Ya the method of going to the home galaxy, that is, the method of entering the interior of the home galaxy through the four-dimensional cosmic space debris layer on the periphery of the home galaxy.

Obviously, the home galaxy is a paradise.

For Zhang Xiaogang, it is no exception.

Only here can he let go of all his burdens and worries. It's just that Zhang Xiaogang knew that this was just a temporary relaxation, and he couldn't stay here forever. What ensures the safety of the home galaxy is not the advanced science and technology that Luo Jinyong obtained from the space debris of the four-dimensional universe, but the powerful human civilization. If human civilization is defeated in the family war, then the home system will also be completely destroyed.

Zhang Xiaogang was very emotional.

After being resurrected by Ali, Zhang Xiaogang had very little free time, but as long as he had a moment of leisure, he felt that everything he experienced after the resurrection was like a dream. Even in the period of underground civilization, Zhang Xiaogang did not expect that human civilization would have today. Compared with the human civilization that Zhang Xiaogang knew before, the current human civilization is not only more powerful, but also has become unrecognizable.

In fact, the current human civilization is no longer a real human civilization.

In terms of morphology, the current human individuals are significantly different from the human individuals that Zhang Xiaogang is familiar with. The fundamental reason is that after coming into contact with and understanding other intelligent civilizations, the aesthetics of human beings have undergone earth-shaking changes, and self-evolution has also led to the fact that the gender difference of human beings is no longer obvious. As a result, the human form is significantly different from the natural stages of evolution.

Of course, the biggest change is in the ideology.

In Zhang Xiaogang's understanding, what human beings pursue is only how to live better. Even in the period of underground civilization, the ideals of most people were only to seek a better life. It can even be said that almost all of them are fighting for self-success, or self-interest.

Obviously, what human civilization is pursuing today is no longer the self-success of individuals.

This kind of change has nothing to do with self-evolution or the great integration of intelligent civilizations, but with the achievements of human civilization and the general environment. Especially after the realization of all-round militarization and the struggle of all people for the survival of human civilization and even the alliance of intelligent civilizations, the cultural concept of mankind has undergone earth-shaking changes, and almost everyone has realized the relationship between self-struggle and civilization as a whole.

Of course, this is a good change.

In a sense, this change is also the basis for human beings to transcend intelligent civilization and become a higher existence.

To put it bluntly, if human civilization is still only fighting for itself, and everyone is struggling for self-worth, then human beings will never be able to surpass intelligent civilization, because this is the characteristic of all intelligent civilizations, and it is also the main basis for distinguishing intelligent civilization from higher existence.

It's just that Zhang Xiaogang doesn't think that this kind of change will definitely bring good results.

What makes Zhang Xiaogang a little ironic is that the changes in human civilization, especially the changes in cultural concepts, are actually caused by him.

Obviously, this is also where Zhang Xiaogang sighed.

He can influence human civilization and has the ability to change human civilization, but he cannot control this influence and cannot determine the new face of human civilization.

There are not many inhabitants on the planet Home, and even after the number of human legions exceeds 30 billion, the number of legion leaders who come here to reproduce is less than 3 billion. In other words, less than one-tenth of the legion commanders were given the right to reproduce, to be precise, to be precise, to be rotated to reproduce.

According to Zhang Xiaogang's arrangement, each couple will have three to five offspring at a time, and will accompany the children to grow up for the next 20 years. In other words, even if the reproduction offspring is counted, there are only more than 10 billion inhabitants on the home planet, which is not much different from the heyday of human civilization on Earth.

These residents all live in cities that have been planned and built for a long time.

On the home planet, the city only occupies a small part, and most of the places maintain a natural environment similar to that of the earth, and through the material formed by the imitation of the star core, a variety of animals and plants are derived, and these animals and plants constitute the Anthropocene realm that Zhang Xiaogang is familiar with.

Of course, this was not Zhang Xiaogang's original intention, but Luo Jinyong's arrangement.

It's just that the Anthropocene realm that Luo Jinyong is familiar with is not much different from what Zhang Xiaogang is familiar with. In other words, what Luo Jinyong misses most is the earth before it was invaded.

It is precisely because of this that Luo Jinyong set up a satellite similar to the moon for the homeland star.

Through this satellite, a tidal environment similar to that of Earth was simulated on the home satellite.

All in all, apart from the difference in size, there is almost no discernible difference between Homestar and its satellites and the Earth and the Moon.

Of course, on the home planet, not only more than 10 billion people live, but also store all the history of human civilization.

It can be said that this is also Luo Jinyong's special arrangement.

In every city of the home planet, there is a large-scale library, and every resident can access the information stored in the library through the information network at any location, and this information is mainly the historical materials of human beings, that is, the development experience of human civilization.

In a sense, in the process of growing up, the descendants of reproduction receive the most human history.

Zhang Xiaogang did not raise any objection to this.

The reason is very simple, only by knowing the history of mankind can we understand the current situation of human civilization, and can we form a complete and comprehensive individual consciousness, become a unique person, and have a sense of identity as a member of human beings, and serve the interests of human civilization.
