"Mr. Qin! Mr. Wang! Captain Qiu of the Dijiang spacecraft, they sent back a video message. Do you want to open it?" Wang Bin of the command center and Mr. Qin also have many experts specializing in alien and language. They had gathered at the command center as early as when the Dijiang spacecraft captured the alien civilization aircraft, Waiting for the news from the Dijiang.

    "Open the video message!" Qin said.

    With the order of old Qin, the relevant personnel of the command center immediately opened the information sent back by the spacecraft Dijiang.

    Later, Wang Bin and Qin Lao watched the video seriously.

    However, until this video was all played, Qin Lao and Wang Bin and others were unable to recover for a long time.

    After all, the situation of the Milky Way galaxy and the classification of civilization in the Milky Way Galaxy mentioned by this alien civilization are fundamentally different from what they imagined, and even different from the classification of cosmic civilization proposed by Carl, a former scientist.

    The classification of civilization proposed by Karl before is based on energy. As long as the level of civilization reaches the level of first-class cosmic civilization, it can collect all resources on the whole planet and dominate everything on the planet, including volcanic eruption, earthquake, tsunami, typhoon and so on. It can be said that on this planet, first-class civilization is the God of the planet.

    In addition, civilization at this level has also had a certain Aerospace capability and can carry out large-scale migration among nearby planets in the galaxy.

    The secondary civilization, that is, the civilization of the planetary system, has reached this level and has the ability to sail at the speed of light.

    In addition, they can make full use of the energy of their stars and completely control their solar system. You can live and shuttle freely on all planets in the solar system without worrying about energy problems. Because you know how to make efficient use of the endless energy emitted from stars, society has been highly developed and development tends to be highly accelerated.

    They can even build energy collection systems like the Dyson sphere in their planetary systems.

    Most importantly, when civilization reaches this level, it is almost indestructible.

    At least all natural and man-made means known to human civilization can not touch a hair of them.

    Even if there is a supernova explosion near their galaxy, they can''t die.

    They can move their galaxies away from exploding stars, or simply use the energy of the explosion.

    As for the tertiary civilization, it is even more frightening, because in Carl''s civilization index, the tertiary civilization is already a galaxy God,

    They are not limited to their planetary system, but the whole star system, such as our Milky way.

    They can use all the energy in their own star system, including the energy of black holes and other unknown celestial bodies of human civilization, such as white holes. It can be said that this kind of civilization has gone beyond imagination.

    As for civilization above the third level, it is even more unimaginable.

    However, the Galactic division method they know from the mouth of this alien civilization is obviously not divided by energy, but mainly by aerospace capability. Although others cannot be excluded, they are not the most important.

    If divided according to the previous kalda civilization index, almost all civilizations in the galaxy are still in the state of primary and secondary civilizations. After all, according to the "sea" of the blue star civilization, there are only a few civilizations with superluminal Aerospace capability in the whole galaxy, Moreover, these civilizations have not been able to create the technology of building Dyson ball like the secondary civilization in the Karda civilization division.

    In other words, the most advanced civilization in the galaxy has not yet reached the level II civilization in the kalda civilization index.

    This surprised Wang Bin and everyone in the whole command center.

    In addition, compared with Qin and others, Wang Bin''s heart is more speechless. After all, in Wang Bin''s original cognition, there will be at least one or two real tertiary civilizations in the whole galaxy, that is, the God making civilization in the supernatural universe.

    But the reality is not so. In such an infinite galaxy, there are only Aerospace civilizations, and there is no real third-class civilization at all.

    As for whether what the alien "sea" from the blue star civilization said is true, Wang Bin has no doubt. After all, if the "sea" of the blue star is really a cosmic pirate, he can''t say it at all.

    What''s more, according to the "sea", the blue star civilization is a secondary civilization, but Wang Bin saw from the video that from the physical strength of the "sea" of the blue star, there was no trace of genetic transformation on his body, not even mechanical modification of his body, so their civilization was definitely not a secondary civilization in the normal sense, It''s just a secondary civilization in the galactic civilization division method.

    If you really get the classification method of civilization in the universe, the blue star civilization is at best only the middle and late stage of the first-class civilization, and it is still a castrated version of the first-class civilization.

    After all, just in terms of aerospace capability, the space warplanes of their blue star civilization can not be compared with the space warplanes made by human civilization, because it can be seen when human civilization fought with alien civilization flying saucers before.

    Although according to the "sea", they are space pirates. In terms of weapons, they may not be as good as the regular fleet of the blue star civilization, or even the fighters of the previous generation or even older of the blue star civilization fleet, and their performance is far worse than the fighters in active service of the blue star.

    But it will never surpass in essence, so according to Wang Bin''s guess, the technology of blue star will never surpass the Pirate Group in essence.

    In other words, in fact, even the blue star civilization is only a first-class civilization, the middle and late civilization. They at least master the technology to penetrate the natural wormhole of the Milky way. Therefore, in essence, even if the real blue star civilization comes to the earth, human civilization is not without the power of war.

    In addition, according to the "sea", their Pirate Group is on the way to and from the solar system. In five years at most, their fleet will cross the wormhole and reach the edge of the solar system.

    After that, at most half a year, the Pirate Group will enter the inner circle of the solar system.

    In other words, what human civilization saw with the large radio telescope before may well be the remaining fleet of the pirate regiment in the mouth of the "sea". As for why, in the telescope, the main ship of this fleet will be so large, Wang Bin is not very clear. However, Wang Bin guesses that it is likely to be the main ship of their pirate regiment, Only when the large magnetic sail engine is deployed can it have such a large volume. In fact, their main ship is only the size of our Dijiang.
