In fact, it is very simple to say that the Ming Empire established a communication relay station, but in fact, it was not all smooth sailing in the construction process, and the middle twists and turns were abnormal and difficult.

Since Zhu Lei and the others left the solar system, two years later, the Ming Empire sent another fleet to fly from the Ming Empire's native solar system towards the vast universe.

Compared with Zhu Lei's fleet, this fleet is much larger in terms of number and scale.

After all, Zhu Lei's space fleet is just a trade fleet, although the three spaceships are very large, and the largest volume is more than 120 kilometers, but because these spaceships are all armed merchant ships, they cannot be compared with real space warships in terms of combat effectiveness.

Although each spaceship in Zhu Lei's fleet carries many professional combat spaceships, and their combat effectiveness should not be underestimated, once they encounter a civilization of the same level as themselves, then they will not be able to make any effective moves with these three spaceships and the space warships carried by the three spaceships.

The main role of the fleet led by Zhu Lei is to trade with other civilizations in the universe, not to fight like real space warships.

What's more, it is impossible for Zhu Lei and them to carry out a real space warship, or a professional space battle fleet to go to the Ocean of Light, because in that case, they may be resisted by all the civilizations in the entire Ocean of Light, after all, there is an essential difference between driving a space warship and driving an armed merchant ship.

And this fleet, which departed two years later, is different, this is a professional space fleet that is really used for space warfare, and due to the huge number of warships in the fleet, there are tens of thousands of space warships.

Therefore, this fleet can't reach the Black Bear Civilization Star Domain by impulse at all, and can only use the warp speed engine to fly towards the target, you must know that this is a distance of more than 150 light years, even if the Ming Empire now has a warp speed engine that is more than ten times the speed of light, it will take more than ten years to get there.

What's more, the Ming Empire can't be sure whether there is already a civilization there, if there is already a civilization there, if the civilization level is not very high, then for the sake of the Ming Empire's communication relay station, the Ming Empire must take action against these civilizations.

After all, this communication station is very important to the Ming Empire, so the security of this communication station must not be threatened by any civilization, so no matter what, if there is really a civilization in that place, war is inevitable.

The way the fleet of the Ming Empire set off was that it could not pass through the wormhole, and could only sail at warp speed to reach the target.

According to the estimation of the Ming Imperial Academy of Sciences, the place where the relay station is to be built is only less than fifty light years away from the star field where the black bear civilization is located, and it is about to come out of the barren star field, so there should also be a civilization there, and the specific civilization level is not yet known, if it is just a primitive civilization, then there is no threat to the relay station of the Ming Empire at all, at least in thousands or tens of thousands of years, there is no need to worry about the relay station of the Ming Empire being threatened.

If the level of civilization has exceeded the third level and reached the fourth level, becoming a real cosmic civilization, then the Ming Empire must destroy the other party for the plan of the Ocean of Light, that is, it cannot destroy the other party, at least let the other party become a vassal state of the Ming Empire.

Who knew that after the fleet of the Ming Empire arrived at the Kara civilization and set off again for warp flight, it ran into trouble, when the fleet of the Ming Empire finished its first warp flight, it found itself in a meteorite belt, and the size of this meteorite belt is very wide, a distance of nearly 100 million light years is a meteorite belt, because the spacecraft is in the meteorite belt and cannot fly at warp speed, which is a very big trouble for the fleet of the Ming Empire, you must know that the fleet is in the meteorite belt, Even if it is a regular flight, it has to slow down, although the fleet of the Ming Empire, even when it is a regular flight, the maximum speed can reach four-fifths of the speed of light, but in this meteorite belt, the fleet of the Ming Empire cannot sail at full speed at all, and can only move at a very slow speed.

In the absence of a way, the fleet of the Ming Empire could only move towards the target at a speed of about 10% of the speed of light, so the fleet of the Ming Empire flew in this meteorite belt of nearly a light year for more than ten years before it got out of the meteorite belt, and even lost several spaceships in the process of passing through the meteorite belt.

Fortunately, there were no casualties.

However, the Ming Empire ran into trouble again at the end of the second warp flight, but this time it was different from the previous one, it was the Ming Empire's spaceship that directly broke into the battlefield of the two civilizations, although the civilization level of both sides of the war was not high, and they had not yet reached the level of the fourth-level civilization, and the Ming Empire's fleet suddenly broke into the area where they were fighting, which suddenly caused a misunderstanding between the two sides.

Without any communication, both sides directly attacked the fleet of the Ming Empire. However, the spaceship of the Ming Empire is not a civilization that has not even reached the level of fourth-level civilization that can be broken, but since there are civilizations that dare to attack the fleet of the Ming Empire, then they must be prepared to be retaliated, although the other party's civilization is still a primitive civilization that has not even reached the fourth-level civilization.

So the fleet of the Ming Empire and the fleet of these two civilizations fought, and the result was naturally no surprise, the level of civilization technology between these two civilizations and the Ming Empire was too different, and after the war started, the two civilizations did not even have room to fight back, the war ended in one day, and the Ming Empire defeated these two civilizations with zero losses.

Then the fleet of the Ming Empire directly descended on the home planet of these two civilizations, destroying these two civilizations by the way, and occupying the home planet of these two civilizations, but after occupying their home planet, they notified the earth that what happened after occupying these two life planets was not a matter of this fleet, and naturally the Ming Empire would send another colonial fleet to rebuild these two life planets.

And this fleet started to set off again, flying towards the intended destination, and the subsequent flight was quite smooth, and there was no accident to reach the scheduled destination, but after arriving, the fleet of the Ming Empire found that as the scientists of the Ming Empire calculated, there was really a fourth-level civilization in the star field here, and there was more than one.
