As the Green Star civilization has become a subordinate race of human beings, the Green Star civilization has also taken root in the star system, and at the same time, it is expanding rapidly.

There are thousands of complete tripolar biochemical civilization science and technology materials in science and technology, as well as the help of all human biological scientists, in less than ten years, the scientific and technological level of the Green Star civilization has reached the peak of the three-pole civilization, and at the same time, it has begun to integrate the basic materials disciplines of human beings, preparing to break through the fourth-level civilization with biology and basic materials science as the backbone.

However, the scientists of the Green Star Civilization can only assist in the study of biological disciplines, and the rest of the basic material discipline materials can be directly copied from human beings. Anyway, the route taken by the Green Star civilization is very clear, it is mainly based on biological disciplines, supplemented by basic materials disciplines, so the basic materials science system with a little human characteristics has no impact on the exhibition of the Green Star civilization, after all, the basic materials discipline is the most compatible discipline, and the racial characteristics contained in it are also the least, and there is no problem with the Green Star civilization copying.

After nearly ten years of exhibition, the clansmen of the Green Star Civilization have all left the race flagship and relocated to the planet-level mothership made by humans for the Green Star Civilization. The size of the planet-class mothership is nearly two-thirds of the Earth, and the mass is seven-tenths of the total mass of the Earth.

The interior of the planet-class mothership is completely built with reference to the living planet, a small artificial sun, based on the living environment of the Green Star civilization, virtual sky, artificial gravity and atmospheric pressure, etc., are all used on this mothership, it can be said that except for the outermost layer of metal shell, this mothership is actually no different from the living planet.

And the race flagship of the Green Star civilization has now been built from scratch, and the technology used is completely at the peak level of mankind, and with the equipment and prehistoric civilization equipment obtained by the Green Star civilization from the temple of civilization and race, the entire race flagship is now one of the most powerful combat forces of the Earth Federation.

That's right, it's the Earth Federation, not the Green Star civilization. According to Xiang Gan's statement, your Green Star civilization does not need to go to the battlefield, and we humans are responsible for anything, so it is useless for you to ask for a race flagship, it is better to hand it over to the Earth Federation for scientific exploration.

Well, no matter how shameless this reason is, but the Green Star Civilization really doesn't have any opinion on Xiang Qian's approach.

The Green Star civilization is not a war maniac, and now all the clans are living inside the planet-class mothership built for them by the Earth Federation. In such a situation, the Green Star civilization feels very good, it has nothing to do to grow flowers, raise grass, cultivate biological weapons or something, who is full of food and runs out to fight with the race flagship.

In this way, the human race used the most pinnacle technology after 25 years of integration to build this race flagship, and the final combat test result turned out to be on the same level as the Advance Satellite Fortress. At the same time, in terms of maneuverability, because of the curvature engine, the flight degree of the race flagship is dozens of times that of the Advance.

In order to wield the power of the equipment of the Civilization Race Palace, Xiang Qian deliberately installed ten sets of auxiliary energy systems and a large amount of backup energy in the race flagship. With the support of these energies, it seems that in addition to the planet-level fortress gravity cannon of the evolutionary civilization, which can destroy the racial flagship, even the antimatter fortress cannon of the pioneer civilization cannot break the protective shield of the racial flagship with a single blow.

Now that human science and technology have reached the critical point of the pinnacle of the three-pole civilization, the industrial base and the level of evolutionaries have all reached the standard, as long as the scientific and technological theory of the fourth-level civilization can be studied, it can break through to become a fourth-level civilization. However, this scientific and technological theory is a difficult problem, you must know that after the formation of a unique scientific and technological system of human beings, if human beings want to break through the fourth-level civilization, they must have scientific and technological theories that human beings specialize in.

For example, now human beings take energy, high-energy physics, and quantum mechanics as the core of science and technology, even if the scientific and technological theories proposed must be within the scope of these three kinds of science and technology, and the scientific and technological theories that break through the fourth-level civilization belong to which discipline they belong to, then the main body of science and technology in the future of mankind must be dominated by that discipline.

At the same time, the more esoteric the scientific and technological theories that break through the fourth-level civilization, the faster the civilization level will rise, and the greater the racial potential. If human beings are chosen to take the Great Unified Theory as the core, integrate the distorting force of space, and form a new set of Great Unified Theory, it is completely possible to break through the fourth-level civilization, but such a scientific theory is estimated to lose its role in guiding mankind when it reaches the peak of the fourth-level civilization. At that time, when human beings are trying to develop new theories, it will be difficult.

So now all scientists are putting forward theories one after another, what dark matter, cosmic dimensions, parallel space, interstellar positions, particle transformations and so on have all emerged, but some of these theories are too extreme, some topics are too big, and the span is too long, and they are not suitable for human beings to break through the fourth-level civilization.

In the end, Xiang Qian decided not to break through the fourth-level civilization first, anyway, in the current Big Magellanic Galaxy, human beings belong to the top series of civilizations, and there is no danger at all. Moreover, the subordinate races of the human race have not yet been found, so they are not in a hurry to break through the fourth-level civilization first, and after the subordinate races are found, they are making a breakthrough.

"Boss, now a pioneer civilization and four evolutionary civilizations are heading towards our star system, and at the same time, the other party's probe has reached 7.8 billion kilometers outside the star system and is exploring the star system, may I ask if it will be destroyed."

"Don't wreck, let them come." Xiang Qian looked at the scene of a planet fortress with a large number of warships on the screen, and said indifferently.

"Okay, boss."

Xiang Qian didn't pay attention to this matter after taking a look, with the current strength of the human race, let alone this little strength, even if it was ten times over, it would not be able to pose any threat to the human race. So he has nothing to worry about at all, and this kind of thing has not happened once or twice in recent years, and he paid attention to it at first, but it was boring after a few more times.

After all, as long as it is not a brain-dead civilization, after seeing the situation inside the star system, no civilization will be stupid to do it. Basically, after determining the situation inside the galaxy, you turn around and leave.

There are no less than dozens of such things alone, how can Xiang Qian still be in the mood to pay attention to this matter. In his opinion, this is another civilization that is about to run away, and it doesn't matter whether you pay attention to it or not.

However, this kind of thing has been born a lot in the past few years, because when various civilizations explore the ruins of prehistoric civilizations, there will be a treasure map, which is said to be a treasure map that is just a star map marked with the location of special rare metals. With the exploration of the remains of prehistoric civilizations, most civilizations have known the value of special rare metals. It can be said that special rare metals are important materials for the future civilization exhibition, and without special rare metals, it is equivalent to no genetic nuclear force armed, and without gene nuclear force armed, it is impossible to break through the fourth-level civilization.

So now the whole Big Magellanic galaxy is very chaotic, like at the beginning, everyone was busy with their own work, looking for prehistoric civilizations separately, and the era of technology has passed. Now that the Great Magellanic Galaxy is at war all the time, civilizations get treasure maps all the time, and then use this treasure map to find the star system where special rare metals are located.

After arriving in the star system, if it is not occupied, then occupy it yourself, if it is occupied by other civilizations, you can fight it, and if you can't beat it, you can run or join other civilizations to attack. At this time, the powerful war potential of the evolutionary civilization and the pioneer civilization will be reflected, basically the wanderer civilization has not been fully developed in these years, and the warships with less than 3o thousand will be destroyed.

Some fleets were wiped out, racial flagships ran away, some surrendered and became subordinate races of pioneer civilizations or evolutionary civilizations, and the most tragic ones were those civilizations that were directly blown up racial flagships, and such civilizations had only one way to go.

It can be said that these civilizations in the Big Magellanic system have been in a state of war, grabbing resources, robbing the remains of prehistoric civilizations, and the law of the jungle is undoubtedly revealed.

However, this qiē has no impact on human beings, and now human beings have been exhibiting, and Xiang Qian has no idea of snatching the relics of prehistoric civilization with those civilizations. What mankind has to do now is to accumulate, accumulate war potential, accumulate science and technology, and now is not the time to fight mankind.

Five days later, when Xiang Qian received the starry sky prompt again, he was speechless.

"You're sure they're coming at us, not changing course." Xiang Qian said to the starry sky.

"That's right, these five civilizations have rushed towards us after receiving the probe signal, and they have started the curvature voyage, and they are expected to reach the outer edge of the star system in 1 month." r1152
