Although the construction of the Sky City by the Ming Empire on the planet Kara has affected the normal life of the Kara civilization to a certain extent, after all, such a huge sky city, the impact of the construction must be very large, and the sky is full of various small space vehicles full of goods, after all, the sky city is built in the atmosphere of the planet, and the height of the sky city in the atmosphere will definitely not exceed 5000 meters, so large spacecraft must not be able to directly enter the atmosphere. And these small aerospace vehicles have become the absolute main force in the construction of the empty city.

Although the construction of the Sky City has brought a certain influence to the Kara civilization, the construction of the Sky City by the Ming Empire has also added great vitality to the Kara civilization, and even the construction of the Sky City has provided countless jobs for the Kara civilization.

After all, although the Kara civilization is a fourth-level civilization, and the population is only a few billion, but because the Kara civilization is a pure scientific and technological civilization, when it reaches the level of the fourth-level civilization, most of the industries of the Kara civilization have been replaced by intelligent machinery, so the unemployed population is very large, although the civilization has reached this level, it is basically impossible to starve to death, and the government of the Kara civilization is bad, and everyone in the Kara civilization provides the most basic living security to ensure that these people are not starved to death.

Moreover, the home planet of the Kara civilization, the planet Kara is more than three times larger than the earth, so the Kara civilization basically has no shortage of food, but the unemployment rate remains high, which also leads to the high crime rate of the Kara civilization, and some people even become traitors to civilization and betray the Kara civilization to serve other civilizations.

After more than five years of construction, the first sky city suspended on the planet Kara was finally completed, the size of this sky city is nearly forty or fifty kilometers, and the maximum carrying capacity can live more than 50 million people, of course, this is only the first suspended city built on the planet Kara, and then the Ming Empire will build more suspended cities on the planet Kara, so after the completion of this sky city, the construction of the next sky city will begin immediately, but this time the construction of the sky city is no longer only one, Rather, multiple cities in the sky are under construction at the same time.

However, in the next step, Zhu Lei did not personally participate in the construction of Sky City, but handed it over to his subordinates.

And because the Kara civilization has become a vassal state of the Ming Empire, and it is also the only official vassal state, the Ming Empire's support for the Kara civilization is very strong, including all-round support for technology, culture, and art.

Especially in terms of science and technology, the support is quite strong, such as the manufacture of various hovering cars on the earth, the manufacture of hovering trains, and the manufacture of surrendered cities, as well as the manufacture of space cities, as well as various space factories, space shipyards, etc.

Although these technologies were before the Kara civilization joined the Ming Empire, as a fourth-level civilization, the Kara civilization basically had the ability to manufacture, and some of them were already very popular, such as the suspension car was very popular in the Kara civilization, as well as the space city and space factory, etc., the Kara civilization also has these facilities in space.

However, the Kara civilization is much more backward than the Ming Empire, after all, the Kara civilization is now in the space shipyard, and the largest space warship that can be built is only about 3 million tons, but the Ming Empire has been able to build tens of millions of tons of warships, which is several generations more advanced than the Kara civilization.

Not to mention the more huge space city, the space city designed and manufactured by the Kara civilization itself is only a few million tons, where is it like the space city made by the Ming Empire, which stretches for dozens of kilometers, and the maximum carrying capacity of the population has reached the scale of hundreds of millions.

However, although the Ming Empire unconditionally supports the Kara civilization with these technologies, due to the scientific and technological differences between the Ming Empire and the Kara civilization, as well as the different priorities of scientific and technological development, there are many technologies that the Kara civilization cannot master in a short period of time, let alone understand these technologies.

Even with the help of the Ming Empire, it would take at least a hundred years for the Kara civilization to master these technologies, especially high-end technologies such as materials technology, biotechnology, photonic technology, etc.

According to the judgment of the scientists of the Ming Empire, with the IQ of the scientists in the Kara civilization, it will take at least two or three hundred years to master, not to mention that these technologies are only in the entry stage, and some have not even reached the entry, so there is no shortcut to these technologies at all.

For example, the precision mechanical technology of the Ming Empire has reached hundreds or even thousands of times the intimacy of the Kara civilization, but if the Kara civilization wants to master these technologies, it must start from the most basic machine tool manufacturing technology.

The second is biotechnology, although according to the determination of the scientists of the Ming Empire, the Kara civilization is more suitable for the development of biotechnology, that is because the Kara civilization is a scientific and technological civilization that combines machinery and electronics, and because it entered the cosmic age early, it does not attach much importance to biotechnology, resulting in them in biotechnology even more than human beings more than 100 years ago, the earth is still in the era of the nations is even worse.

It can even be said that in terms of biotechnology, although the Kara civilization has a very good talent, due to the wrong direction of their development, their civilization has only been in the embryonic stage of biotechnology until now.

Therefore, the high-end biotechnology of the Ming Empire, the biological scientists of the Kara civilization can't even read it, let alone understand it.

Therefore, in terms of biotechnology, the Kara civilization must be learned from scratch, starting from the biotechnology of the Ming Empire more than a hundred years ago, and because the Kara civilization is not like the earth, everyone is a practitioner, and the physical fitness and IQ have been greatly developed.

Therefore, their IQ cannot reach the level of human beings at all, even if the Ming Empire creates the Demon Clan Cultivation Exercises for them in the future, they will not be able to reach the level of human IQ, this is because of the innate attributes of the exercises.

After all, as a subordinate civilization, it must not be stronger than the suzerain's civilization.

Because Zhu Lei decided that in another year or two, after all the work on the planet Kara is stabilized, he and the queen of the Kara civilization and some of the high-level officials will set off to return to the mainland of the Ming Empire.

After all, nearly 40 years have passed since he set out on the expedition, and he has begun to feel homesick for such a long time, and there are many people in the entire fleet who miss their families day and night like him.

After all, not all of them brought their families with them.

This return, Zhu Lei will lead 1/3 of the fleet back to Earth, and the remaining 2/3 will be stationed in the Kara galaxy to guard against other advanced civilizations, as well as civilizations of the same level as Kara, after all, the universe is not as harmonious as people see.

Without the support of a strong military force, no matter which civilization is even a high-level civilization, it is in danger of being destroyed at any time, so it is absolutely necessary to station a strong army in the Kara system.
