So when Zhu Lei and they set foot on Kara Star, the Earth side also began to actively prepare for immigration, after all, most of the fleet led by Zhu Lei are soldiers, although a huge fleet will definitely be stationed in the Kara galaxy in the future, and most of the soldiers and warships of the fleet led by Zhu Lei this time will stay in Kara Star, and Zhu Lei himself will only lead a small part back when he returns, but most of the scientists and research ships will still return to Earth. After all, most of these scientists who followed the fleet this time were the top scientists of the Ming Empire, although the Kara civilization also needed these scientists, but no matter what, they were mainly based on the Ming Empire.

However, there are still some top scientists left, and these scientists will do long-term research on the atmosphere, soil and biology of the planet Kara in the future.

However, although the fleet of the Ming Empire will have a total of more than 100 million people left, it is not visible at all compared to the entire Kara planet that is larger than the three planets on Earth, and according to the analysis of the scientists in the fleet, the Kara planet can accommodate at least four or five billion people, although to get rid of the intelligent life lizardmen on the Kara planet, hundreds of thousands of people, and the future population growth space, all Kara planets can also accommodate at least one or two hundred billion people.

This can greatly alleviate the pressure on the population of the Ming Empire, and all the headquarters on the earth side know that after Zhu Lei sets foot on the planet Kara, they can't wait to organize immigrants, because the current population pressure of the Ming Empire in the solar system is too great.

In addition, because the environment of the planet Kara is very well protected, and the size of the planet Kara is more than three times that of the earth, the concentration of aura on the planet Kara is also relatively high, although it is still a little worse than the earth with the planetary spirit array, but this aura concentration is not bad.

After all, the smallest spaceship in the human fleet has a mass of more than one million tons, not to mention a space battleship more than ten kilometers long, such a huge tonnage landing on the planet Kara is simply unrealistic, and the energy required is also astronomical, so all the spaceships of the human fleet stay in the geostationary orbit of the planet Kara.

Most of the people in the fleet began to use the aerospace vehicles on the spacecraft to land on the planet Kara, and because the threat of the virus was clear, the ordinary people of the Kara civilization also drove their own space vehicles and various small spacecraft to visit the human fleet.

After all, in the eyes of the Kara civilization, the Ming Empire defeated them with such an absolute advantage, and made the Kara civilization a subsidiary civilization of the Ming Empire, so many people on the planet Kara want to see for themselves what kind of civilization it is.

Of course, in addition to these ordinary people who came to visit the warships of the Ming Empire, many experts and scholars of the Kara civilization also came to visit and learn about human technology, politics, culture, etc.

However, the objects of communication between these experts and scholars are different from ordinary people, although they are also very curious about the spaceships of the Ming Empire, and they are also very much looking forward to the future Kara civilization can also serve on these warships, but they are most concerned about the communication in their own profession.

After the Ming Empire and the Kara civilization signed a subsidiary civilization agreement, with the continuous deepening of the exchanges between the two races, the more the Kara civilization understands the politics, economy, culture and other aspects of the earth, and is very shocked that human beings can develop into a quasi-fifth-level civilization in just over a hundred years, although the earth civilization is not yet a fifth-level civilization as they imagined before.

However, in addition to the fact that human beings are inferior to the fifth-level civilization in terms of warp engine, most of the other technologies are no worse than the fifth-level civilization, and in terms of military strength, they are much stronger than the black bear civilization.

Then, a few months after the signing of the treaty, Queen Carla once again stepped on the battleship Yong'an of the Ming Empire, although they had been on this spaceship for a month or two before, but given that this was one of the most powerful space warships of mankind, he still felt very shocked, after all, such a huge behemoth floating in the universe was too impressive.

Especially the various weapons of the Ming Empire, because the Ming Empire and the Kara civilization have not signed a formal subsidiary agreement, so many weapons have not been shown to them, after all, it is a human and Kara civilization or a hostile relationship, but now the subsidiary agreement has been determined.

Moreover, the Kara civilization, as a third-level subsidiary civilization of the Ming Empire, and the only subsidiary civilization, no longer needs to be kept secret, not to mention that these weapons are all weapons of thirty or forty years ago for the current Ming Empire, and they are relatively outdated, so exposing these weapons is no longer relevant to the Ming Empire.

Therefore, this time Queen Kara visited the battleship Yong'an, which was very different from the last time, all the cannon ports were opened, revealing various weapons inside, and the shock given to Queen Carla after Yong'an this time was even more powerful.

And then Zhu Lei showed Queen Kara the powerful communication equipment of the Ming Empire, as well as the radar equipment on the battleship.

And the scientific and technological content of these equipment to Queen Tara is no less shocking than seeing the strategy connected to various weapons, the Kara civilization, as an authentic fourth-level cosmic civilization, is still relatively familiar with the surrounding fourth-level or fifth-level civilization technology, and he has never seen such communication equipment as the Ming Empire, you must know that the Ming Empire is more than ten light-years away from the Kara galaxy at this time, but the communication can communicate in real time, and the detection range of the radar is as high as more than one light year, and there is no delay, No wonder the Ming Empire had the upper hand in the war.

"Dear Queen Kara, I am the emperor of the Ming Empire, I sincerely invite you and the high-level of your civilization to visit the mainland of the Ming Empire, that is, the solar system, I think all the earthlings will welcome you."

In the communication, the emperor of the Ming Empire, to the Kara civilization and their high-level sent an invitation to visit the solar system, my high-level Ming Empire leaders think that as a vassal of the Ming Empire, they must have an understanding of the solar system and even have a sense of belonging, but now the Kara civilization has just joined the Ming Empire to become a subsidiary civilization of the Ming Empire, so they invited the high-level of the Kara civilization to the solar system as a guest.

"Your Majesty the Emperor, thank you for the invitation, I and the high-ranking members of our civilization will definitely come to the solar system as guests, and Your Majesty the Emperor,"
