After hearing this, Xiang Qian also knew that this matter was big, and if any race wanted to develop, the most basic number was the population, and if there was not enough population, there was no need to say anything.

"Patriarch Green Gasson, don't worry, I want to know what the total population of the Green Star Civilization is at present." Xiang Qian didn't know why this happened, and there was no such hint in the information stored in the eggs. Regarding the hint of the fourth-level civilization in the picture, he had seen it many times, and there was no such thing as a population at all.

"The total population of the Green Star civilization is now more than 8.46 billion people." Lu Gesen has been busy solving this problem for a month, so he is very sensitive to these numbers, Xiang Qianyi blurted out when he asked, without any hesitation.

"Then how many people did you have before you broke through the fourth-level civilization?" Xiang Qian continued to ask.

"More than 4,230 million, this is the number before the breakthrough, this number and the current total population ......" Lu Gesen did not say me, but he realized that the star is not.

Fools know that there is a problem with this number, and even if it is rounded, it is not so made. Directly doubled the number jù, if it is said that the population growth problem of the Green Star civilization has nothing to do with breaking through the fourth-level civilization, fools don't believe it, this is too coincidental.

After listening to this, Xiang Qian began to recall the special hint in the egg storage device about breaking through the fourth-level civilization, and he remembered very well that there was no hint about the population problem at all. Some just say that before breaking through the fourth-level civilization, deepen the racial heritage, and the deeper the racial heritage, the greater the racial potential after breaking through the fourth-level civilization.

At that time, his idea was that racial heritage was equal to the accumulation of science and technology plus material reserves. There is no concern about the population at all. After all, as an evolutionary civilization, the human population has no limit and no life extension. Looking for it has already broken through the 20 billion mark. So he didn't count the number of humans as a race at all, but now judging from what happened to the Green Star civilization. The number of people is also a kind of racial heritage, and it is also the most critical one, but this problem has been ignored by him.

"Patriarch Green Gerson, I'm sorry, I think the question you mentioned has a lot to do with breaking through the fourth-level civilization. I don't know if you noticed the Avengers, they broke through the fourth-level civilization in order to reduce the number of races in order to reach the fourth-level civilization standard, and broke through the fourth-level civilization.

Any civilization can do the same, as long as the biotechnology is strong enough. After breaking through the fourth-level civilization, although the racial potential will be reduced, it will reduce the threshold by one. But now it seems that after breaking through the fourth-level civilization, there will be many restrictions, one of which is population. Xiang Qian thought for a while and said.

At this time, Xiang Qian really understood how important it was to break through the fourth-level civilization, all parties and all sides had to be ready, otherwise there would be a problem in any place, and the development potential of the entire race. There will be a huge impact.

If you don't have your own race's unique technology system, you will fall behind in terms of technology. Without sufficient resources, the genetic nuclear force armament of the fourth-level civilization race flagship and the clan will not be able to achieve the best, which will also affect the subsequent development.

A tricky approach like the Avengers. Although it has broken through the fourth-level civilization, it is changing directions to obliterate the potential of the entire race. A race with a population of only 200,000, even if it is a fourth-level civilization. What kind of future can it have? However, if you break through the fifth-level civilization, it is a question whether you can reach the peak of the fourth-level civilization.

With the development of science and technology. Any one discipline will be divided into countless small disciplines, and these countless small disciplines will break through. Only by accumulating can science and technology progress. There is not enough population, there are not enough scientists, what does the whole civilization take to develop.

Now Xiang Qian can already foresee that in the future universe, the plundering of science and technology between civilized races will become the mainstream, and this is an inevitable trend.

"Don't be sorry, our Green Star civilization is already satisfied with such a population. If it weren't for the Earth Federation, our Green Star civilization would not have achieved its current achievements at all, so we can calmly face such a situation. Lu Gesen said very sincerely, he didn't blame Xiang Gan, at that time, the Green Star Civilization chose to break through the fourth-level civilization was agreed by the entire race, and now that such a thing happens, Xiang Qian is not to blame at all, after all, Xiang Qian doesn't know what will happen after breaking through the fourth-level civilization.

"Well, the human race has not yet broken through the fourth-level civilization, so the number of people will not affect us yet. I'll give the order to the human race to start the population plan. I will let one-third of these new populations study biology to make up for the demographic shortcomings in the future technological development of the Green Star civilization. Xiang Qian thought for a moment and said.

It's not that he wants to be Lei Feng, because now the Green Star Civilization and the Earth Federation are one, and the Green Star Civilization's science and technology cannot be developed, and it will not do any good to the Earth Federation. And it is not a big deal to add a biological discipline to the main development direction of mankind in the future.

After knowing the population limit of the fourth-level civilization, those civilizations that were not sufficiently prepared before breaking through the fourth-level civilization would definitely not think that population would be the first major difficulty for their future development. Therefore, in terms of scientific and technological development, even if human beings add a discipline, it will not drag down the development of the earth itself. Because the number of scientists in mankind is unmatched by any civilization.

"Will this have any adverse impact on human development?" Green Gesen was very happy to hear this, but he still showed a hesitant expression on the surface.

"No, I'll take this into consideration, you go and get busy with your business first, I want to make some long-term plans for the future, and some of the plans I made before have to be changed now."

Closing the communication, Xiang Qian leaned back in his chair and began to think, fortunately, the Green Star Civilization broke through the fourth-level civilization first, and the population of the Green Star Civilization was relatively small, and the speed of discovering this problem was relatively fast. If human beings really broke through the fourth-level civilization first, then some would cry.

"Starry Sky, contact Sephiroth." Xiang Qian thought for a while, and then told Sephiroth about this matter first, and talked about other questions later.

After connecting the communication, Xiang Qian immediately told Saphiroth about this population restriction civilization, telling him not to rush to break through, even if the flagship of the civilization race is built, the population must be increased first. At the same time, the number of people cannot be blindly increased, and if there is an emergency, it must also ensure that the Silver Wing Civilization can break through the fourth-level civilization in an instant, which needs to be well controlled.

After agreeing with Sephiroth, Xiang Qian informed the new emperor of the Mandi tribe, Kaia, and told them to increase the number of people, and there was no need to limit them, and the more the population, the better. At the same time, on the earth's side, Xiang Qian also issued an order that all human beings began to create human beings, with a target of 100 billion people.

However, this is to increase the population, but it cannot break through the fourth-level civilization, so the combat effectiveness of the Earth Federation will definitely have a low period in the future. When the evolutionary civilization breaks through the fourth-level civilization, then the advantages of the Earth Federation will not be obvious.

Faced with such a problem, Xiang Qian summoned scientists from all the civilizations of the Earth Federation to discuss a solution to this problem.

After a month of discussions, the current scientific and technological advantages were demonstrated, and the project of the Galaxy Battleship was finally determined.

The galaxy battleship is a battleship designed according to the concept of the Earth Federation for the flagship of the fourth-level civilization race, and it is said that it is a battleship, but it is basically a moving star system, and all the inside of the star system are equipped with fourth-level civilization defense weapons, so that they are not afraid of the attack of the fourth-level civilization race flagship. However, this moving galaxy cannot be as large as the current star system, and must be reduced.

The final design size of the galaxy warship is within 80 billion kilometers in diameter.

After the project was confirmed, the busiest belonged to the Green Star Civilization, because the core of this galaxy battleship was the Green Raystar, so in the next time, the Green Star Civilization would be busier than the Silver Wing Civilization, which was building the flagship of the fourth-level civilization race.

With the big move of the Earth Federation, the surrounding civilizations have also begun to get busy. Xiang Qian exchanged scientific and technological materials and fourth-level civilization weapons and equipment for the help of countless small races around him.

If you don't let them help, the construction of a galaxy battleship is still bigger than the construction of a fourth-level civilization race flagship, although it is much worse than the fourth-level civilization race flagship in terms of technology content, but in terms of workload, it is n times more than the construction of a fourth-level civilization race flagship.

Within 50 light-years of the Earth Federation, countless small races transported various materials to the Earth Federation through guò transport spaceships, the most important of which were water and organic matter. These materials will be cultivated by the Green Star Civilization into a fourth-level civilization plant planet fortress to protect the safety of the Earth Federation.

Thanks to the help of countless small races, the construction of galactic warships progressed much faster than expected, and planets were assembled and plant weapons were planted on the surface of the planets. Giant vines traverse the entire star system, linking planets one by one.

In less than half a year, the star system where the Earth Federation is located has changed greatly, the metal planets in the entire space have disappeared, but they have been replaced by green planets, and at the same time, in the cosmic void inside the star system, there are all kinds of biological spores floating, some have sprouted, and some are still absorbing nutrients.

The Greenman, on the other hand, did one of the most important tasks, which was to carry the stars. If a galaxy warship wants to move, it must have enough energy, and the only ones that can provide a huge amount of energy are stars. As for the star inside the galaxy, it has long been used as a core energy source.

However, a star is simply not enough for a galaxy battleship, according to the calculations of scientists, even if you want a galaxy battleship to simply change direction, it needs all the energy of a star to be the most powerful. And for a galaxy battleship to overcome the gravitational pull of the black hole at the core of the Big Magellanic galaxy, move in the opposite direction, and get out of orbit, then at least 11 stars need to have all their energy.

In this way, it would add up to twelve stars to ensure the basic operation of the galaxy battleship. (To be continued......)
