When their parents learned the news, it soon spread all over their relatives and friends.

    Du Xingyu connected the phone for more than an hour and was severely praised by his family. For fear of delaying his rest, the family hung up the phone.

    "The care and greetings of so many relatives and friends..." Du Xingyu felt a little warm in his heart, which also strengthened his determination to continue research and development of science and technology.

    The doomsday scene of an asteroid hitting the earth, he doesn''t want it to happen! Even if it is found, human beings should have scientific and technological means to deal with it!

    Du Xingyu opened the science and technology simulator and continued the project research of "heavy recoverable launch vehicle".

    The current research progress is 5%.

    "Use 100000 energy points to improve progress!" Du Xingyu uses the obtained energy points to speed up the progress.

    In the science and technology simulator, there are various simulation schemes for rocket research. These schemes are not all successful, but also have failures and defects.

    "The research and development failed, and the progress increased by 0.5 percent!" the technology simulator warned.

    "Another 100000 points!" because of the explosion on the Internet and news interviews, Du Xingyu has directly obtained millions of energy points, which is enough for him to squander now.

    "R & D failed and the progress increased by 0.5 percent."

    "Successful research and development, progress increased by 10 percent."

    On the science and technology simulator, there are detailed scientific research materials, which are directly printed in Du Xingyu''s mind, so that he can quickly absorb and use them.

    He put all the energy points he obtained into Speeding up the research progress. Soon, a complete and feasible manufacturing scheme of heavy recyclable launch vehicle appeared on the science and technology simulator.

    ……

    After the news interview with Du Xingyu was broadcast, there was a heated discussion in the society again.

    Du Xingyu''s attention at station B suddenly soared to one million people. The video of his rocket launch was also circulated on the Internet and praised.

    Some people stood up and began to question the authenticity of Du Xingyu''s rocket launch.

    The Q & A app was just above the top, and a respondent named Yu Bo, who was certified as an "aviation power expert" and a member of the International Aviation Technology Association, stood up.

    He wrote down the answer to Du Xingyu''s hottest question: "Du Xingyu''s success is our sorrow! Just a college student, how much does he know about aerospace? As an insider, I know the difference between practice and theory."

    "It''s impossible for him to make a recyclable rocket on his own! All the parts and structural systems of the rocket in the video follow the strict rocket production process. Even a real rocket engineer can''t fully grasp it. How did he do it?"

    "I can''t help but wonder if there is an expert behind him... There is no doubt that the genius created by the expert is very successful, won public attention, and even became a rocket engineer before he graduated!"

    "Aerospace science is not a gilded tool for some people. I hope relevant departments will investigate it carefully!"

    Yu Bo himself is an aviation power expert. In addition, many people believe in conspiracy theory. Seeing his answer, a large number of people immediately chose to believe it and scolded Du Xingyu and the people behind him.

    Glazed color: "big answer is great. I also think he can''t complete these independently. It must be hype!"

    Anonymous user: "hehe, I dare say that Du Xingyu''s family background is not simple, so he joined the space agency as a rocket Engineer? Who is responsible for the problems with the rocket he designed in the future?"

    Jane A: "college students make rockets, which can be recycled? That''s ridiculous! It must be made by someone else, let him launch!"

    Kong Kong Kong: "I''m also a student of Hangda! I don''t believe it was made by him! Let''s say, even if he really knows all about it, he can''t finish making it for more than five years!"

    Some people help Du Xingyu speak. For example, Xia Tong, a colleague of the space agency, often wanders around.

    Seeing this comment, Xia Tong directly angered Yu Bo: "@ Yu Bo, I advise you not to come with your mouth open!"

    "We have checked Du Xingyu''s rockets, and there is no problem. Moreover, his own understanding of aviation science is much better than some old stubborn people with rigid ideas!"

    "The field of aviation science and technology is a field of exploration. No matter how old you are, you can advance in this field as long as you have real talent and hard work. If you have time for speculation, you''d better do more research..."

    Yu Bo fought with him and sent a message again: "I doubt it because I know how difficult it is! Let a hairy boy be a rocket engineer and participate in major projects! Hehe, can he bear the consequences if the rocket goes wrong?"

    "Let me just say that. I just doubt that Du Xingyu''s rocket manufacturing is a fraud!"

    Xia Tong: "this is slander!"

    Yu Bo: "slander? OK, I''ll find evidence!"

    Yu Bo also lost his temper in an aviation research institute. He began to carefully look for loopholes in Du Xingyu''s video.

    There are many clips in Du Xingyu''s rocket video, which is to avoid the video being too boring and the disclosure of important scientific and technological secrets.

    However, this has become evidence of Yu Bo''s real hammer Du Xingyu''s "fraud". He edited the video and made it into a "real hammer collection" and published it online: "Du Xingyu''s rocket manufacturing is fraud? There are eight doubts in total!"

    In the video, he used his professional knowledge to point out all kinds of doubts. And at the end of the video, he said, "these eight places are only the most suspicious. I won''t say any other doubts."

    "I use my professional guarantee in the aviation field for 30 years. Du Xingyu''s rocket production on the Internet is definitely hype and fraud! Aviation science is a serious field and can''t tolerate any mistakes!"

    "If people who cheat get honor, it will be the sorrow of our astronauts!"

    At present, Du Xingyu''s topic of making rockets is normalizing. As soon as Yu Bo''s video was released, countless media began to forward it and rub the heat, which once again triggered a hot discussion on the Internet.

    Most people have no concept of rocket production, and Yu boben is an expert in this field and a member of the International Aviation Technology Association. Many people believe him.

    "Is it true that the student made a rocket?"

    On the Internet, there are also requests for a thorough investigation of this matter.

    On station B, some up owners also made videos to question Du Xingyu. Many netizens asked Du Xingyu to respond, making a lot of noise.

    In this regard, Du Xingyu just smiled after reading it. There were too many people questioning it, so he didn''t have time to fight back one by one.

    Therefore, he only made a paragraph and wrote: "facts speak louder than words. I have participated in the new launch vehicle project. The Mars mission will be launched on July 23!"

    July 23, nearly two months from now, is the launch date of the Mars probe of the Huaxia space agency. It is also the first time in Chinese history to launch a probe and a Mars rover to Mars.

    The rocket used for launch was made by Du Xingyu''s project team. The rocket has already been made, and what Du Xingyu needs to do is to transform the rocket and add his own designed rocket recovery device.
