Of course, in recent years, although Tiangong technology has focused on the research and development of plasma engine in terms of engine, in recent years, because Lao Huang has invested a lot of human and material resources in the research and development of controllable nuclear fusion engine in their world, Wang Bin has also obtained a lot of Technology about controllable nuclear fusion engine in Lao Huang''s hands.


    Although most of these technologies have been sealed up by their Tiangong technology as technical reserves, if necessary, they can use these technologies at any time. At the same time, with the ability of Tiangong technology, Wang Bin believes that they can definitely develop the most advanced nuclear power engine comparable to Lao Huang''s in the world in a short time, Even more advanced.


    This is not Wang Bin bragging. It can be seen from the development of sky technology in recent years.


    Then, after Wang Bin and Lao Huang talked for a while, Wang Bing said to Lao Huang, "Lao Huang, for this transaction, Tiangong technology still agrees in principle, but I have another condition. I hope Lao Huang can agree, and this condition is also very good for you!"


    "Mr. Wang! Please speak!" old Huang nodded and replied.


    "Since the alien civilization in your world is coming soon, and you are ready for it.


    I hope that in the future, the war data you keep in the war with alien civilization can be shared with us, whether victory or defeat.


    In this way, even if the alien civilization in my world does not come for the time being, it will enable me to understand the alien civilization, especially the civilization above the aerospace level, and develop the corresponding weapons and technologies for space war. In this way, it will also be of great benefit to Lao Huang.


    After all, once the alien civilization of your world comes to the earth, the industry of your world will definitely be hit by the other party for the first time, and all war weapon R & D institutions will definitely be hit for the first time, so your world will be destroyed in weapon R & D and production.


    I think as an aerospace civilization, the aliens who came to your world absolutely understand.


    So I can also promise that once your alien civilization will unite you to have an interstellar war, Tiangong technology can definitely trade with you as usual, and the price will never increase, "Wang Bing said.


    After listening to Wang Bing''s words, Lao Huang also nodded, because he knew very well that once an alien civilization came to the earth, the war would not be finished in a moment and a half, and according to Lao Du, it was very normal to fight the Xiao war between various civilizations among the stars for a hundred years, Even some wars between the two civilizations have been fought directly for thousands of years.


    Although it is said that after more than ten years of preparation, China in his world has transferred most military related industries underground, no one can guarantee that these industrial chains that have been moved underground will not be discovered or destroyed by these alien civilizations.


    Once these industrial chains are attacked and destroyed by alien civilization, it means that human civilization has lost the ability to make all kinds of weapons, and once the weapons in his hand are consumed, what will be waiting for human civilization? Lao Huang knows very well in his heart. After all, between his world, earth civilization and the upcoming alien civilization, The civilization level gap is too big.


    Therefore, at any time, the importance of the technology mall becomes more prominent, because at any time, all the weapons they need can only be purchased from various stores in the technology mall.


    Moreover, according to his observations during this period of time, the price of these weapons is not high in peacetime. Take ordinary firearms for example. In peacetime, an energy coin can buy at least thousands or even tens of thousands. However, once there is a war in their own world, the price of these firearms will also rise sharply, Even after the industry in their own world was devastated, the price of weapons in these malls will rise sharply, and some even reach the level that one energy coin can only buy one small pistol.


    Therefore, when the alien civilization of Lao Huang''s world really comes and the appearance civilization really destroys the earth''s industrial system, the importance of Wang Bin''s Tiangong technology is reflected.


    After all, Wang Bin''s universe, the science and technology of human civilization, is not the most advanced in the mall and the zero level human civilization universe.


    But it''s not bad. After all, the civilization level of Wang Bin''s universe has reached more than level 0.9.


    Most importantly, as like as two peas of two civilizations, the two universes are very similar, and even many conventional weapons are identical in performance. So the soldiers who are bought from Tiangong technology can also operate without obstruction, which is very important during the war.


    As for the war data, it is absolutely easy for Lao Huang and them to obtain if there is an alien civilization invasion, so it is absolutely worth it for Lao Huang and them.


    Then, after talking with Lao Huang for a while, Wang Bin returned to the real world and began to prepare things for Lao Huang.


    Although, in recent years, Wang Bin, their Tiangong technology and the world''s officials have been trying their best to develop aerospace technology. The consumption of resources is very huge, and the consumption of various aerospace materials is becoming more and more huge.


    However, in recent years, their research and development of Tiangong technology and materials has not fallen behind, and in recent years, they have also achieved great achievements, and many large-scale production lines of materials have been completed at this time.


    At the same time, the materials that have been developed before, such as the oldest special glass and special steel, are also expanding the production line again and again. Therefore, in the real world, in recent years, Tiangong technology has not only produced enough materials for Tiangong technology, officials and major Aerospace institutions in the world, but also sold a lot in the mall, Even for the materials produced in recent years, Wang Bin and Tiangong technology have stored a lot.


    After all, not to mention anything else, just here in the desert, the material industrial zone producing all kinds of special materials has an annual production capacity of hundreds of thousands of tons. You know, this is special materials, not ordinary steel and other common materials.


    Therefore, Wang Bin and Tiangong technology can still get the materials of millions of energy coins ordered by Lao Huang.


    Therefore, after returning to the real world, Wang Bin came to a special warehouse of Tiangong technology, found out the materials needed by Lao Huang, put all these materials in the technology mall, and then traded with Lao Huang.
