When Zhu Lei's fleet was fighting with the Pirate of Light, outside of 50 astronomical units, many civilizations were using their own radar technology and sending various detection equipment to observe the direct battle between the so-called fifth-level civilization Ming Empire's trade fleet and the light and dark civilization.

This battle has made the civilization in the Ocean of Light more profound in the concept of a fifth-level civilization, and there has never been a civilization in the Ocean of Light that has advanced to a fifth-level civilization, so there is no understanding of the specific combat effectiveness of the fifth-level civilization.

And this battle is nothing to the fleet of the Ming Empire, not even a small test, but it is a very big shock to these civilizations in the Ocean of Light who just watch the whole battle process.

The whole battle can be said to be a completely one-sided slaughter, from the beginning of the battle to the end of the battle, they didn't even see the Ming Empire lose a spaceship, and even the loss of space fighters is very small, what surprised them even more was that the people in the fleet of the Ming Empire, their personal combat effectiveness was also very strong, and in the absence of any scientific and technological equipment, they could directly fight with the photon pirate group space fighters, and the combat effectiveness was even more powerful.

"Is this a fifth-level civilization? It's so powerful that it's impossible to put into words. The observer of the Swan civilization said to himself.

"Yes, it's too powerful, not only is it completely overwhelmed by the pirate group of light in terms of technology, but even the personal combat power is very powerful, the personal combat power of the totem civilization, one of the overlords in our ocean of light, is already the most powerful in the entire ocean of light, but compared to the human civilization of the Ming Empire, there is still a big gap, if you don't use scientific and technological products, even the totem civilization can't compete with the cosmic fighters of the photon pirate group, And this person of the civilization of the Ming Empire can directly compete with the space fighters of the Pirate of Light, and it is even much more powerful.

Could it be that advancing to the fifth level of civilization not only has to meet certain standards in terms of science and technology, but also has hard rules in terms of personal physical fitness? ”

At this moment, the Swan civilization, and the other civilizations that were observing on the side were all messy.

After the war between the Space Trade Fleet led by Zhu Lei and the Pirate Group of Light, they directly started the warp engine and flew towards the Ming Empire's stronghold in the Ocean of Light, after all, they can now contact the mainland of the Ming Empire, so Zhu Lei's current mood is completely understandable.

You must know that Zhu Lei and they have left the earth and come to the Ocean of Light for nearly 50 years, and they have not been able to contact the mainland of the Ming Empire for such a long time, and they always feel unsteady, for the people of the Ming Empire, the solar system is their root, no matter where they go, no matter where they move, they always worry about their hometown and their relatives in their hearts.

So they are already very homesick, but for the unfinished business of the Ming Empire, for the advancement of civilization, they have to silently endure the emotion in their hearts, and pay everything for the Ming Empire, even their own lives.

For the light and dark civilization behind the Pirate of Light, Zhu Lei would never do this, how could it be so easy to attack the army of the Ming Empire.

Of course, if other civilizations in the Ocean of Light are attacked by the Pirate Ship of Light, it may be because of the strength of the light and dark civilization, and there is no direct evidence, it will be like this, for the Ming Empire, as long as they know who did it, they don't need any evidence.

Because the Ming Empire is not a weak one, but a strong one, a strong one that surpasses all civilizations in the entire Ocean of Light.

What's more, in the universe of the jungle, the strong civilization has absolute control over the weak civilization, and the weak civilization dares to offend the strong civilization, then they must be prepared to die and exterminate the species.

After all, you must know that the Ming Empire has lost a full double digit number of soldiers in this war, if you don't give them an explanation, Zhu Lei can't get over it in his own heart, not to mention that they are just a fourth-level civilization, and they dare to offend the Ming Empire, a fifth-level civilization, if they don't give them a lesson, it will be spread out in the future to call the Ming Empire how to gain a foothold in the galaxy.

When the surrounding civilizations observing the war determined that the fleet of the Ming Empire had left, they dared to come to the area where the two sides were fighting, and the scene they saw was simply shocking to them, and the wreckage of the ships and warplanes of the Pirate of Light was floating everywhere in the entire battlefield, and they did not see the wreckage of a spaceship or a space fighter in the fleet of the Ming Empire at all.

Although the Ming Empire lost space fighters in this war, all the lost space fighters were recovered by the Ming Empire into space warships, and the bodies of those fallen soldiers were also recovered.

Prepare to return to the Ming Empire in the ocean of light for cremation after a few points, and when the time is ripe, the ashes of these sacrificed soldiers will be sent back to the Ming Empire's native solar system to return to their roots.

"Xiaorou, have you been doing for the past few decades?" Looking at the familiar face on the screen, Zhu Lei said unconsciously.

In fact, in the fleet of the Ming Empire, whether it is an officer or a soldier, or Zhu Lei himself, there is no one who does not miss the Ming Empire and his family.

Previously, because the distance between the Ming Empire and the place where they are now is too far, even if the Ming Empire uses neutrino communication, it is impossible to connect with the mainland of the Ming Empire at such a distance, so even if they are homesick, there is no way, and they must wait until the Ming Empire communication relay station is established before they can practice with the Ming Empire.

The relay station of the Ming Empire must be built 150 light-years to 200 light-years away from the solar system, and the location of the construction is also very important in terms of security, and even the army must be sent to guard there, so it is not until now that the relay station of the Ming Empire has been built.

In fact, the Ming Empire had gone through a lot of detailed calculations as early as when Zhu Lei and them set off, and they had also made calculations for neutrino communication, and the result of the calculation was that neutrino communication could only communicate within a radius of 200 light years, and once it exceeded 200 light years, then even if it was used Zhongwei communication, it was powerless.

So since Zhu Lei and the others set off, it didn't take long for the Ming Empire to send another fleet to fly towards the star field 150 light years away, preparing to find a suitable place there, preferably a living planet, to build a communication relay station, and then as long as this communication relay station is completed, then whether it is in the star field of the black bear civilization, or most areas of the Ocean of Light, you can directly contact the mainland of the Ming Empire.

In this way, the mainland of the Ming Empire can know what happened in the Ocean of Light or the area of the Black Bear Civilization at the first time, which is very important for the entire Ming Empire.
