The Draa civilization is different from the general fourth-level civilization, in addition to their own home galaxy, the territory of their civilization also occupies the two galaxies next door, these two galaxies are not very far from the galaxy of the Draa civilization, both within three light years, and there are also life planets in these two galaxies, so the Draa civilization is actually a very powerful fourth-level biological civilization.

However, although the Draa civilization is powerful, their civilization is not invincible in the periphery of the barren star field, not to mention the black bear civilization outside the barren star system, as well as the fifth-level civilizations such as the Ming Empire in the middle star field of the barren star field.

Even the ant civilization 5 light years away from the Draa civilization is not much weaker than them, because the ant civilization is the same as the Della civilization with hundreds of thousands of years of time, and in these hundreds of thousands of years, the ant civilization has only been upgraded to the top of the fourth-level civilization until now due to the civilization potential, and the same as the Della civilization, even the quasi-fifth-level civilization has not yet arrived, with the potential of their civilization, if there is no special opportunity, they will not necessarily be promoted to a fifth-level civilization in hundreds of thousands of years.

However, unlike the Della civilization, although the ant civilization is a civilization evolved from insects, their civilization does not follow the route of biological civilization, but the route of civilization but the route of energy civilization.

In addition to these two civilizations, there is also a civilization in this star field, but although this civilization is also a fourth-level civilization, it is still inferior to the above two civilizations, after all, the fourth-level top civilization is not a cabbage everywhere, and this civilization is different from the previous two civilizations, the form of this civilization is the most common type of civilization in the universe, scientific and technological civilization, and the potential of this civilization is obviously much higher than the previous two civilizations.

In fact, all the history of this civilization adds up to only about 200,000 years, which still includes the primitive era of this civilization, if you don't count the primitive era, it is only more than 50,000 years from the beginning of the civilization into the industrial age, and in the past 20,000 years, this civilization has been promoted from a third-level civilization to a fourth-level civilization, which shows that the potential of this civilization is still a little.

According to the estimation of the potential value in the universe, the probability of this civilization advancing to a fifth-level civilization in the future is still very high, but it is very difficult to become a sixth-level civilization, with a chance of less than one in a thousand.

This civilization is the ape-man civilization, the ape-man race is a relatively pure scientific and technological civilization, especially in the achievements of mechanical technology, even many fifth-level civilizations are inferior, the ape civilization is inferior to the other two civilizations due to the relatively short time of its rise, after all, the other two civilizations are not to mention the things before entering the universe age, even if they have entered the universe, it has been hundreds of thousands of years since they entered the universe.

So of course, the heritage of these two civilizations is not to say that the ape-man race can be compared, and because these two civilizations are all heterogeneous civilizations, compared with the mainstream scientific and technological civilizations in the universe, the life span of these two civilizations is much longer, and if there is no accident, the civilization of these two civilizations can basically live to be more than three hundred years old, especially the ant civilization as an energy civilization, and the people of their race can basically live about five hundred years old if there is no accident, but it will not exceed six hundred years old.

And the ape-man race is different, because the ape-man civilization is the most conventional scientific and technological civilization in the universe, although the ape-man civilization is already a fourth-level civilization, and the strength is also on the article, after all, there are two fourth-level top civilizations around them, if they don't have a certain strength, their civilization is not pure in the universe.

Even if the lifespan of the ape-man race is now a fourth-level civilization, through genetic medicine and other means, the general lifespan of people in their civilization can only reach about one hundred and eighty years old, and a few people can live another fifty or sixty years, but this is already the best.

However, although the life span of the ape-man civilization is much shorter, their fertility is very good, which is not comparable to the other two civilizations at all, and the total population of each civilization is only about 10 billion, while the total population of the original human civilization is more than the sum of the other two civilizations.

It is precisely because of their large population, although they are weaker than the other two civilizations in terms of civilization level and technological strength, but it is precisely because of their large population that they can survive in this star field and compete with the other two civilizations.

Three light-years away from the Dra-civilization, the calm starry sky was dim, and because there were no stars nearby, even the closest stars were three light-years away, and all the people who would not be civilized would come here at all.

So this star field is very calm, plus there are no asteroids, meteorites and other cosmic celestial bodies around this star field, this star field looks very empty, empty and calm has become the eternal theme of this star field, but today this star field is abnormal, a little ripple suddenly appeared in the calm starry sky, and as time went by, the ripples did not calm down but intensified, and the spatial fluctuations caused by the ripples quickly spread in all directions.

As time went by, these ripples became farther and farther away, and finally this ripple was discovered by the civilization near this star field, after all, such a strong space ripple can be found as long as you are not a fool, not to mention that several nearby civilizations are all fourth-level civilizations, and even in the fourth-level civilization, these civilizations are relatively powerful existences, so it didn't take long for these civilizations to discover the space ripples in this star field, and always pay attention to the existence of this space.

At the same time, the space combat departments of these civilizations sounded a piercing alarm almost at the same time, and these civilizations were not civilizations in the barren star field, and they knew nothing about anything.

Although they are actually a Desolate Star Domain civilization, since this is the periphery of the Desolate Star Domain, they still have a lot of contact with things in the universe, and even purchased a lot of technology from the Black Bear Star Domain outside the Desolate Star Domain, especially the ape-man civilization as a technological civilization.

It is precisely because these civilizations have some understanding of the situation in the universe that they are so nervous when they see such spatial ripples appear in that starry sky, because these three civilizations all know what kind of situation will cause the if, that is, when the spaceship is traveling at warp speed at the beginning and end.
