Because these researchers who want to develop larger spaceships think that the universe is no bigger than the earth. Perhaps there are more than 100000 tons of aircraft carriers on the earth, and their volume is very huge, but the universe is boundless. Apart from others, just the size of the solar system can not be fully understood by the current level of human civilization.


    So even a 100000 ton spaceship, placed in the universe, is very small, and there are many things that can be destroyed.


    But compared with smaller spaceships, their survivability will definitely be stronger and their resistance to various dangers will definitely be stronger.


    However, the manufacture of larger spaceships is also a huge problem for today''s human civilization and today''s Tiangong technology. After all, human civilization, even a real 100 ton spaceship, has not been manufactured, let alone 100000 tons.


    Therefore, in Tiangong technology, they made nearly 10000 tons of spacecraft for the first time, which is very radical. After all, human civilization is facing the threat of unknown civilization. If they are not radical, they can''t.


    But it''s too radical and it''s not the way. If it''s too radical, there will definitely be problems.


    What''s more, it took Wang Bin and Tiangong technology nearly three years to design a 10000 ton spacecraft. This is only design. If manufacturing is added, it will take at least four years.


    Therefore, if it is a 100000 ton spacecraft, it will take at least more than ten years according to the judgment of Wang Bin and others. Wang Bin can''t wait for such a long time. After all, no one knows when alien civilization will come.


    Of course, for spaceships of more than 100000 tons, Wang Bin and Tiangong technology have not given up. Now they have begun to design, but it''s hard to say when they can complete the design.


    When Wang Bin just entered the Tiangong technology store of the technology mall, he found that Lao Huang had already been waiting for him inside. At this time, Lao Huang''s face was very bad and sad.


    Seeing this, Wang Bin thought and found that with the passage of time in Lao Huang''s world, it was time for the appearance civilization to invade their planet.


    So he opened his mouth and said, "Lao Huang, your situation is not very good. Is there something wrong in your world? Has alien civilization come to the earth?"


    "Ah! Yes! Now a huge chrysanthemum has appeared over juxia city in our world. According to Lao Du, this huge chrysanthemum is a big insect bridge from a distant galaxy to the solar system.


    In other words, with the emergence of the big bug bridge, the appearance civilization can come to the earth in less than half a year at most. However, with the current situation of human civilization in our world, there is no way to the big bug bridge in the sky. We can only watch the appearance civilization come.


    According to Lao Du and others, even if human civilization has reached the aerospace level civilization, there is no way for such a big insect bridge, let alone the human civilization in my world, even the aerospace level civilization has not been reached.


    In other words, for the arrival of alien civilization, we now have no way but to fight.


    However, over the past ten years, we have made a lot of preparations because we know in advance that the appearance civilization is coming, including the black Great Wall plan and my golden Great Wall plan, but there is still a big gap compared with the aerospace civilization. "Lao Huang sighed and said.


    "Lao Huang, in the past ten years, you have done enough for your world. It can even be said that in the past ten years, your scientific and technological strength has been greatly improved by you.


    In the past, according to the evaluation of the science and technology mall, your world''s science and technology level was at most equivalent to the level of 0.75 civilization, but now? Your world''s science and technology level has reached the level of more than 0.95.


    You have not only successfully realized controllable nuclear fusion technology, including thermonuclear fusion and cold nuclear fusion, but also successfully manufactured a large number of spaceships and aerospace aircraft for low and medium earth orbit operations, as well as a variety of space unmanned combat platforms.


    In addition, there are countless combat weapons in the earth''s atmosphere. Not to mention ground combat weapons, only air combat weapons. According to your last disclosure, there are more than 100000 individual manned combat aircraft, and most of them are brand-new aircraft made in recent years, as well as various unmanned combat aircraft, which are calculated in millions.


    And your robot force, the so-called Gundam force, has also reached more than 10000.


    In addition, there are all kinds of large-scale defensive weapons on the ground, and there are countless. Therefore, based on the strength of human civilization in your world, if the alien civilization, that is, the Taoyu fleet, does not use star killing and other weapons of mass destruction, human civilization, even without the help of any divine civilization, has the power of World War I.


    So don''t blame yourself too much, Lao Huang. After all, you''ve done enough in the past ten years and you''ve completely deserved anyone.


    What''s more, in your world, in addition to the golden Great Wall project you presided over, there is also Lao Du''s black Great Wall project. Due to your prior warning, all the super soldiers of the black hand Great Wall project have entered the army and received comprehensive training in the inside before they wake up, So that they are not compared with the previous scientific research in terms of body and mind, will or other aspects. They are all Chinese soldiers. I believe that with their existence, there is absolutely no problem for China to defeat these alien civilizations. " Wang Bin said.


    "I hope so. If possible, I really hope these appearance civilizations will not come. In this case, although my efforts in recent years will be in vain, it is the greatest happiness for the country and the nation!" said Huang.


    Wang Bin also nodded. Although in Wang Bin''s world, in recent years, both Tiangong technology and other parts of the world have been actively building the Earth Defense circle, if possible, neither Wang Bin nor other parts of the world hope that alien civilization will really come.


    What''s more, compared with the world where Lao Huang lives, they clearly know their enemies. The world where Wang Bin lives is much worse. Wang Bin and they don''t even know who the enemy is, let alone what level the other party''s scientific and technological level has reached. If the other party''s civilization level has reached more than level II, Even if the earth has Wang Bin''s help, it may not be able to defeat each other.
