"What? You want to build a carrier rocket?" Rao has seen many talents and ideas. Lin Guangyan, the teacher in charge of the laboratory, was stunned.

    With a slight smile in his eyes, he looked at Du Xingyu and asked, "do you know what you are doing? You want to make rockets alone, or can you fly tens of kilometers, recyclable launch vehicles!"

    "Yes, Mr. Lin, I know very well that this is my plan." Du Xingyu handed him the plan. Although Lin Guangyan felt very unreliable in his heart, he still read it carefully.

    There are other teachers in the office, who also have some opinions on Du Xingyu''s ideas.

    "Young man, it''s OK to build rockets, but you have to find more classmates!"

    "Don''t make rockets as simple as you think. It''s not a simple aviation model. It''s very difficult to really follow the manufacturing principle of rockets!"

    "You can design a small rocket. I remember some students have done it before. It''s not bad."

    "Simply flying into the sky, it''s a flying monkey. The structure of the rocket is tens of thousands of times complex!"

    "Eh?" Lin Guangyan, who was reading the plan, made a surprised voice, and his expression became more and more serious.

    "What''s the matter?" other teachers in the office were also curious.

    "Did you really write this?" Lin Guangyan looked up and looked at Du Xingyu in surprise.

    "Yes." Du Xingyu nodded.

    "This design is like a model! It feels a little possible!" Lin Guangyan looked at the instructions in the plan and the relevant plans and designs of rocket manufacturing.

    The content is rich, detailed and well grounded. Even in some places, he hasn''t seen it for a while. It seems that it is not the product of a hot mind, but something after careful consideration.

    "Let me have a look!" the teacher next to him came over and looked at the contents of the plan.

    "There''s something!" he cried. "This student has a great head! This rocket design is great, great!"

    "Mr. Zhou Bin, you are an expert in this field. What do you think?"

    The teacher surnamed Zhou watched carefully. His eyebrows gradually locked and his expression became more and more dignified.

    For a long time, he sighed and said with emotion, "good! It''s good to write! It''s the first time I''ve seen such a detailed plan and scientific and reasonable design in more than ten years."

    "Your name is Du Xingyu, isn''t it? Good! I support you!"

    "Teacher Zhou said so, then I must support it." Lin Guangyan smiled and said to Du Xingyu, "I approved the experimental materials and laboratories you want to use!"

    "But one thing, do it seriously! Don''t waste!"

    "Thank you, teacher!" Du Xingyu said quickly.

    "Find more helpers!" Zhou Bin suggested. "If you really do it, it will be much more complex than what is on paper. You can''t be busy alone."

    "Well, I''ll think about it."

    As soon as Du Xingyu left the office, the teachers began to talk.

    "The boy''s idea is bolder than I was. The launch vehicle that can fly to the stratosphere can also be recycled..." Lin Guangyan sighed. "If it can be done, the National Space Administration will have to come to our school to rob people!"

    "Miss Zhou, do you really think you can do it?" someone asked.

    Zhou Bin said: "success or failure is one thing. The key is to have someone do it. Scientific research is like this. On the way to explore the unknown, what is failure several times?"

    "That''s what I said." people thought that exploring the unknown and challenging the impossible was the goal of scientific research.

    With the permission of relevant teachers, Du Xingyu''s rocket manufacturing plan went much smoothly.

    He listed the materials he needed one by one. If the school material library had some, it would be used directly. If not, he would write a report to apply for purchase.

    Throughout the week, Du Xingyu was busy in the experimental building and dormitory.

    "Du Xingyu, can you make that rocket? Why don''t you make this space garbage capture device with us!" Wang Wei suggested.

    "Everything is ready and manufacturing will begin soon." during this period, Du Xingyu has completed all the design drawings on the simulator, and the materials are almost ready to start manufacturing.

    "Walk slowly! He''ll be happy," said Zhao Qingquan.

    In the laboratory, Du Xingyu began to manufacture parts.

    On the technology simulator, his manufacturing progress is 50%.

    In order to obtain the energy points needed by the simulator, Du Xingyu thought of an idea. He decided to take pictures of the manufacturing process, cut it and send it online. If someone is interested, maybe they can harvest some energy points.

    "Hello everyone, I''m Du Xingyu. I''m going to make a recoverable carrier rocket that can fly to the stratosphere. Its estimated carrying capacity is 2.0kg, about the weight of an adult rooster."

    "Now, I need to build a rocket engine. It will have two-stage start-up functions. One is to generate thrust when rising and the other is to generate reverse thrust when falling."

    Du Xingyu arranged his mobile phone and began to make it.

    Rocket manufacturing requires high precision. Even with perfect design drawings, manufacturing is by no means easy. Du Xingyu can only complete it after repeated attempts.

    Back in the dormitory, he cut the video once, condensed it to less than ten minutes, accompanied by some explanations, and prepared to upload it to the Internet.

    Du Xingyu selected a video barrage network called station B and registered a creation number with an ID called "interstellar Explorer".

    Later, he released his first video, "the hardest nuclear engineer in history: making the first phase of a recyclable launch vehicle!".

    After sending out the video, Du Xingyu went to sleep and had a rest. The high-intensity work exacerbated his fatigue.

    On the video network, Du Xingyu was a newcomer and had no fans, so no one watched the video at the first time.

    However, the video network has a small exposure interface for new videos. Some viewers who like to look for novelty will look here.

    In the science and technology partition of the video network, Du Xingyu''s video appeared on the update list.

    "Making rockets? It must be the title party." it was already late at night. Zong Ming, a science and technology lover, brushed this video somewhere in China.

    Zong Ming is a college student who has just graduated. He has been particularly interested in scientific and technological knowledge and information since childhood. He is a frequent visitor to the science and technology zone.

    Seeing this video, Zong Ming''s first reaction was "title party".

    Making rockets? Is there such a big cow in the little broken station? impossible!

    Although he was suspicious, he still clicked in to see. He wanted to know how the up Lord deceived people.

    He clicked in to see, not for anything else, just to spray a few words and release his repressed soul of zu''an.

    Zong Ming opens the video. The first is Du Xingyu''s introduction to manufacturing rocket targets.

    "The ultimate goal of the rocket I want to make is to send a chicken weighing two kilograms to the stratosphere 20 kilometers high, ensure its survival, and successfully recover the rocket body." Du Xingyu said here, Zongming couldn''t help sending a barrage: "bullshit, if you can do it, I''ll believe you!"

    He was patient and continued to look down. The next content is Du Xingyu''s manufacturing of some parts and related introduction.

    In order not to make the video boring, he cut out the boring process and explained it in an easy to understand way.

    Du Xingyu was making parts until the end of the first video.

    Zong Mingfa left a message: "after watching for a long time, where''s the rocket? I think you''re here to make fun!"

    Although he is interested in science and technology, he only stays at the level of enthusiasts and naturally can''t understand Du Xingyu''s video content.

    "But this person really knows a lot." Zongming secretly said, "the production process seems very organized. First pay attention to the wave and see what he can do in the next video."
