These three civilizations have a history of tens of thousands of years due to the fact that they have been promoted to the least level four civilizations, so they have their own unique technologies in many fields.

And communication technology is one of them, at present, these three civilizations have developed the technology that can carry out instant communication within more than ten light years, although the technology they have developed is not mature enough, and can only communicate within ten light years, and there will even be delays, but it is enough for a fourth-level civilization.

After all, the general range of activities of fourth-level civilizations is within 20 light-years, unless there are special circumstances such as envoys to other civilizations, and other special circumstances will go out of 20 light-years, for a fourth-level civilization, the distance of 20 light-years is too far, even if they use their most advanced warships, only 20 light-years will take fifty or sixty years, compared to their lifespan is only a few hundred years, fifty or sixty years is too long.

What's more, unlike the cultivation civilization, the cultivation civilization passes very quickly in the cultivation, just like the earthlings say that there is no time in the mountains and the world has been thousands of years, as long as the cultivation time flies, and their civilization sails in the universe, not only to prevent all kinds of dangers in the universe, but also to endure boundless loneliness, so the distance of 20 light years is far enough for a fourth-level civilization.

Generally speaking, within ten light years is the most important activity area of the fourth-level civilization, and in this star field, like other fourth-level civilizations, the combined activity space of the three civilizations is also about 20 light years, and the key activity space is about 15 light years, and within this 15 light years, there are various detectors of these three civilizations everywhere, after all, the three civilizations of them not only have to defend the other two civilizations of the three civilizations in this star field, but also always observe whether there are foreign civilizations entering this batch of credibility.

Therefore, the spatial fluctuations caused by the imminent appearance of the fleet of the Ming Empire will be known by these three civilizations for the first time, after all, the place where the Ming Empire appeared is only about ten light years away from these three civilizations, and the closest is only five light years away.

As the three civilizations focused all their attention on this star field, the largest vortex in all the space vortex finally had a new change, and something finally began to appear in the direct central cavity area, which was the bow of a spaceship, although it only came out a little bit, and not even a head had yet appeared, but with the area where the spaceship was about to appear, the experts of the three civilizations already knew that this was definitely a professional military spaceship.

It is important to know that there is a very big difference between military and civilian spaceships, and because civilian spaceships basically do not need to conduct large-scale operations in space, they are obviously quite different from military spaceships in terms of defense and attack.

And this upcoming spaceship is obviously very strong, not only has thick armor, the entire bow is clearly angled, and there are even many obvious cannon ports, although these cannon ports are not declared attack weapons at this time, thank you Those attack weapons are all hidden in these cannon ports, and they are not usually exposed at all.

As the spaceship appeared more and more, so did their knowledge of the spaceship of this unknown civilization.

Judging from the appearance of this spaceship, the upcoming fleet must belong to a civilization of level five or above, and this civilization is also the most common technological civilization in the universe.

At the same time, they also found that this spaceship is different from the ordinary pure technology civilization, and there will be beautiful and mysterious patterns on the armor of this spaceship, these patterns are very dazzling, and even exude colorful lights from time to time.

However, for these colorful lights, whether it is the ant civilization or the Della civilization or the ape civilization, they don't care too much, the universe is Chinese and varied, and the three of them are not in the isolated star field, so they still know a lot about other civilizations in the universe.

There are many civilizations in the universe in order to increase the appearance of their spaceships, often when the spacecraft leaves the factory, they often draw various patterns to increase the beauty or mystery of the spaceship, and even some civilizations do not hesitate to sacrifice the performance of the spacecraft to achieve the purpose of the appearance of the spacecraft, of course, there are not many such civilizations, but there are also many.

So these three civilizations didn't care at all, this kind of situation is too common in the universe, and this upcoming fleet of unknown civilizations, although the patterns on their spaceships are very mysterious and give people a very unusual feeling, but they all feel that it is just the patterns that their civilizations spend on the spaceship, in order to add mystery to their spaceship.

It didn't take long for this spaceship to finally reveal its full picture, after seeing the full picture of this spaceship, the people of these three civilizations all gasped, and at the same time their hearts began to chill, the first impression of this spaceship to them was too strong, too huge, and even the Black Bear Civilization, the owner of the Black Bear Heart Jade, did not have such a battleship.

It's not that they look down on the black bear civilization, because they know that the black bear civilization can't make such a huge space warship, after all, the time for their three civilizations to become a fourth-level civilization is not short, as the most powerful civilization around, the black bear civilization of course they should pay attention to, and even attach great importance to the black bear civilization, for fear that the black bear civilization will have bad intentions towards them.

Although the Black Bear Civilization is the only fifth-level civilization in the nearby civilization, the reputation of the Black Bear Civilization is not very good, and there is no way to be famous nearby, who calls the Black Bear Civilization a fifth-level civilization and they are only a fourth-level civilization.

It is precisely because of their understanding of the black bear civilization that it is impossible for the black bear civilization to develop such a huge spaceship, and the material alone is not something that the black bear civilization can do.

You must know that the length of this spaceship that has just appeared has reached 150 kilometers, and the appearance of this spaceship is also fundamentally different from the spaceship made by the black bear civilization.

This huge spaceship has a very good flow line, and it can be seen from the appearance design of this spaceship that the civilization level of this unknown civilization is much higher than that of the black bear civilization, coupled with the thick armor of this spaceship, there is no extra equipment exposed on the appearance of the spaceship, and the water chestnut is clearly Galen has a very hideous feeling.

And since the armor on the spaceship is not the same as the black bear civilization, only in some key parts of the heavy armor, the armor in other parts is obviously much weaker, but this spaceship is different, all the places on the spaceship are basically covered with a thick layer of armor, even around the vent of the spaceship thruster, and these armor give people a very unusual feeling, but they can also imagine that the civilization that can make such a huge spaceship, their material technology must be very advanced, It's not that the black bear civilization can be compared.

In addition, there is a light blue protective shield on the outside of this spaceship, and the transparency of this stupid blue protective shield is very high, and it looks like it doesn't have it, but no matter which civilization of the three civilizations they are, they will not doubt the protective power of this protective shield, after all, the civilization that can make such a huge spaceship and fly at warp speed is definitely a powerful civilization.

Well, no matter what kind of technology such a civilization is, it should not be underestimated.
