In fact, it is the blue star civilization that uses energy from the energy magnetolite. Therefore, the diameter of the spacecraft manufactured by their civilization will not exceed 200 meters, because once the diameter exceeds two centimeters, the energy consumption will increase in geometric multiples.

    At the same time, the magnetic engine used by their civilization could not provide enough power for the larger spacecraft.

    After all, with the technology of mechanical materials and other aspects of the blue star civilization, it is not difficult to manufacture spacecraft with a volume of more than 200 meters. After all, in terms of continuous processing, although human civilization is not as good as their blue star civilization, however, human civilization can also manufacture spacecraft with a volume of more than 200 meters, and the blue star civilization naturally can.

    However, due to energy and engine reasons, their space warships can only stay at less than 200 meters.

    In addition, according to Wang Bin''s judgment, the energy used by the vast majority of civilizations in the galaxy also comes from magneto-optic stones, which is why the "sea" previously said that the main ships of most civilizations in the galaxy would not exceed 200 meters.

    As for the reason why the so-called three-level civilizations in the "Haikou" can produce a volume of more than 300 meters, it is likely that these civilizations are more advanced in the technology of extracting the energy of these magneto-optic stones, or the energy sources they use are more advanced, so that they can make more advanced and larger warships.

    In addition, these civilizations may have developed controllable nuclear fusion technology to enable them to build larger warships.

    As for the way of controlled nuclear fusion, it is likely that it will not be thermonuclear fusion. After all, if you master thermonuclear fusion technology, even if you want to build more huge warships, even a few kilometers or even more, you can supply enough energy provided by thermonuclear fusion.

    In other words, with human civilization mastering cold nuclear fusion technology and thermonuclear fusion technology, human civilization has inherent advantages in entering the cosmic era. As long as other technologies, such as materials and technology, are achieved, it is not impossible for human civilization to manufacture warships with a volume of several kilometers or even tens of kilometers.

    Therefore, for today''s human civilization, the size of warships is no longer a limit. For today''s human civilization, what is missing is time.

    In addition, there is the technology of manufacturing space fighters and space warships.

    We should know that human civilization has just entered the space age, that is, the first-class Aerospace civilization. The design and R & D of space warships are still at the stage of transformation from ocean ships to spaceships.

    Take Dijiang as an example. The object it draws on is the submarine in the sea.

    Even the new spacecraft being manufactured now, that is, the real military level space warship, also draws lessons from submarines in the sea.

    However, compared with the first Dijiang, it is a real military class space warship, and its appearance has also changed.

    Their department of designing and manufacturing space warships by Tiangong technology is also actively referring to various science fiction films, science fiction works and space warships in animation to improve the space warships they want to manufacture next.

    However, after Wang Bin, Qin Laohe and everyone present knew the scientific and technological level of the blue star civilization and the current situation of the galaxy, everyone''s mood suddenly relaxed a lot, as if a big mountain had been removed.

    After all, in the past, when human civilization just saw an alien civilization going to the solar system from a large radio telescope, and the volume and diameter of its alien civilization aircraft could reach at least tens of kilometers, only the high-level interior of human civilization knew how great the pressure was on them at that time.

    Of course, compared with the high-level of human civilization such as Qin Lao, Wang Bin is actually under greater pressure. After all, he knows better than others how powerful the civilization that can create such a huge warship is. The gluttonous civilization of the supernatural universe is the best example.

    But now! Compared with the gluttonous civilizations of the supernatural universe, these civilizations in the Milky way are little brothers, and there is no way to compare them.

    If these civilizations of the Milky way really compete with the gourmet civilization, even if they gather all the civilizations of the whole Milky way, they may not be able to win the gourmet civilization.

    After all, compared with these pseudo Aerospace civilizations in the galaxy, it is actually only a first-class civilization. Taoyu civilization is a real Aerospace civilization, that is, the second-class civilization in the kalda civilization index.

    They not only have the ability to travel at the speed of light in the universe, but also have star annihilation weapons, which is unimaginable for the galactic civilization in the world.

    In addition, according to the information provided by the "sea", all civilizations in the Milky way are not developing in the direction of God making civilization, while the civilization of the supernatural universe, including the top civilization in their universe, is developing in the direction of God making or supernatural civilization.

    Therefore, even a civilization less than level 3, such as Taoli civilization, has the ability to make super soldiers. Although these super soldiers are not as good as the gods in the super God universe, to deal with a civilization that cannot make super soldiers, perhaps as long as a super soldier is sent, a civilization can be destroyed.

    It can be said that these civilizations are suppressed in the dimension of civilization.

    Therefore, for the future development direction of earth civilization, in fact, Wang Bin has already had a plan in his heart, that is, to guide human civilization to develop towards the super divine universe model. After all, compared with ordinary civilization, super soldiers and gods of super divine civilization have absolute advantages.

    Of course, the super soldiers of the super God universe and God also have their own defects, that is, they are extremely dependent on supercomputing and dark plane gene data. No matter whether they are super soldiers or gods, once supercomputing or gene data are hit, they will also be easily killed.

    Therefore, in the future, Wang Bin is not ready to completely develop towards the model of supernatural universe civilization. After all, the civilization model of supernatural universe is only suitable for supernatural universe, not for this universe.

    "Mr. Wang! Now that we know that the alien civilization that will come to the solar system this time is not a regular alien civilization, it is just a pirate group that has been crippled by people.

    Although, if it were a few years ago, our human civilization was only a star civilization, and it was still a civilization without any space war capability at all.

    But now it''s different. If the pirate regiment comes, as long as we give it two years, we will definitely let it go without return? "Old Qin said with some emotion.
