Although the situation of Lao Huang''s world, that is, the supernatural universe, is not very good, they have been ready to deal with it for more than ten years.


    But Wang Bin''s world, although everyone is making great preparations, the time is too short, so compared with Lao Huang''s world, Wang Bin''s real world is far from ready, but fortunately so far, Wang Bin and they have not found the arrival of alien civilization, There is no big chrysanthemum like the super God cosmic bug bridge found in the solar system.


    It can be seen from here that the real world, that is, the world where Wang Bin is located, is facing the threat of alien civilization. The degree of civilization and scientific and technological development must not reach the supernatural universe. Lao Huang and his enemies have to face the scientific and technological level.


    After all, the enemies Lao Huang had to face were not only aerospace, but also the divine civilization that could make super soldiers or gods.


    Even if it is an aerospace civilization, it is already very dangerous for the human civilization in the real world, that is, the world where Wang Bin lives. If you are careless, human civilization may disappear into the universe, but it is better than the enemy is a divine civilization.


    If only aerospace and civilization, under the condition that the other party does not use weapons of mass destruction or star annihilation weapons, human civilization may still be able to resist the other party, but if the other party is a divine civilization, human civilization in the real world has absolutely no resistance.


    Of course, the main purpose of Lao Huang''s coming to the Tiangong technology store in the technology mall is to buy their Tiangong technology products.


    Although Lao Huang''s world has surpassed Wang Bin''s world in many technical aspects due to the development in the past ten years, such as aerospace, the development of powerful weapons and computer intelligence.


    However, there are still many technologies. Lao Huang''s world is still unable to compare with Wang Bin. Take material technology for example. Now Tiangong technology has a lot of materials, and the human civilization in Lao Huang''s world is still unable to manufacture, so Lao Huang must buy them from Wang Bin.


    In addition, because the development direction of gene technology in Lao Huang lock''s world is different from that in Wang Bin''s world, the cost of gene drugs developed by the two universes is also very different.


    After all, the gene technology in Lao Huang''s world has been affected by a large number of divine civilizations, including the influence of DeNO civilization, so its development direction is naturally from the first generation of super soldiers to the second generation of super soldiers, then to the third generation of super soldiers, and then towards the divine body.


    At the same time, the development of super God cosmic gene technology also needs to add some other things, such as adding supercomputer capabilities in Beijing and China.


    However, there is no such development law in the real world, and there is no contact with the gene development law of the universe, so the gene technology developed by exploring nature is completely different.


    The purpose of Lao Huang''s coming to their Tiangong technology store this time is naturally to buy their materials and other necessary things for manufacturing spacecraft.


    At the same time, Lao Huang''s heart is also very clear that with the approaching of their alien civilization, this direct transaction between him and Wang Bin is likely to be the largest transaction in a short time.


    Because once the war starts, it is impossible for him to gather a lot of energy in a short time to exchange energy coins.


    Most importantly, according to the direct disclosure of Wang Bin''s last conversation with him, Wang Bin''s own world has also been threatened by alien civilization at this time, so all kinds of materials and products will give priority to meeting his own needs. Only after meeting the needs of human civilization in his own world will he consider selling them out.


    At the same time, even for this transaction, if he didn''t put forward special conditions, Wang Bin would agree, otherwise it would be impossible.


    As for the condition he proposed, that is, in the process of fighting with alien civilization in his world in the future, once he obtains the technology and even products of alien civilization, he will copy or leave some of them to Wang Bin. That''s why Wang Bin agreed to this transaction.


    After all, the amount of various materials he needs this time is very large, coupled with some very sensitive technologies, such as the high thrust ion rocket technology newly developed by Tiangong technology, that is, the high thrust ion engine technology.


    Although Lao Huang''s world has the existence of DeNO descendants, and DeNO descendants naturally have advanced aerospace technology, for Lao Huang''s world, the aerospace technology possessed by DeNO descendants is so advanced that the human civilization of any world can''t understand such technology.


    The ion medium engine developed by Wang Bin is different. This technology is completely developed by Tiangong technology. There is no threshold for the human civilization in the world where Lao Huang lives. As long as they have the technology, they can realize it immediately.


    As for the aerospace engine technology of other aspects of Tiangong technology, in the past three years, Lao Huang has obtained it from Wang Bin, and some have even exceeded Wang Bin''s R & D process of Tiangong technology.


    Take the controllable nuclear fusion nuclear engine for example. Although Wang Bin and Tiangong technology have developed in the past three years, their maximum thrust is only 50 or 60 tons. However, the research and development progress of the golden Great Wall Project presided over by Lao Huang can produce a 1000 ton controllable nuclear fusion engine.


    It is precisely because of such a nuclear fusion engine that Lao Huang can make their low and medium earth orbit full of various defensive spacecraft.


    At the same time, it is with this nuclear power engine that Lao Huang can have a real spacecraft in their world.


    According to Lao Huang''s introduction, in their world over the past ten years, the golden Great Wall Project presided over by Lao Huang has produced nearly 100 spaceships of various types, of which the smallest spaceship has a tonnage of nearly 1000 tons, while the largest spaceship is an aircraft carrier with a tonnage of more than 100000 tons.


    These are very. At this time, they are well hidden by Lao Huang. They are not exposed to the outside world. Even the systems of these spacecraft are not networked.


    After all, once connected to the Internet, according to the information previously disclosed to them by Wang Bin, it is absolutely impossible to keep secret. Even so, Lao Huang is very worried about whether Taoxi civilization can know the existence of these spaceships.


    The hiding method of these spaceships is actually very simple, that is, the existence of these spaceships as warships in the sea.


    Take aircraft carriers for example. When manufacturing, they design them directly according to the shape of aircraft carriers in the sea. After manufacturing, they do not launch these warships for the first time, but directly launch them into the water to become warships in the sea. If necessary, they will launch and become real spaceships.
