"President Ma has only 30 minutes to discuss with you. In 30 minutes, President Ma will go to Africa to meet the heads of state of the two countries," Mr. Ma''s assistant reminded.

    "I know." Dong Jiangbo met Mr. Ma, once the richest man in China. Although he has now gone to the board of directors of Alibaba, he is still the invisible master of this giant enterprise.

    Now Mr. Ma pays more attention to investment than business operation. When the aerospace industry changed, he keenly noticed Xingyao space technology company and wanted to buy Xingyao space technology directly, but Dong Jiangbo refused.

    "Mr. Ma, nice to meet you again." Dong Jiangbo and Mr. Ma have met for the second time.

    Mr. Ma is wearing a dark Chinese style coat, grey cotton trousers and cloth shoes, which is his favorite hermit dress.

    After the two shook hands, Mr. Ma glanced at the documents sorted out by the assistant. He put his hands on his knees and said, "Mr. Dong, our conditions are very good. All China, I bet that there can be no company better than the conditions we give except Ali Baba!"

    Dong Jiang was embarrassed and said, "it is absolutely impossible to give up the voting right of Xingyao''s board of directors. You must know the reason."

    "Although you are willing to invest, the investment amount has not reached my ideal amount, and we prefer to operate independently, limited to technical cooperation, rather than allowing Ali''s management to enter Xingyao."

    Mr. Ma shook his head and said, "your idea is too shallow. Ali''s participation is the best of both worlds. Our business ability, big data technology and talent reserve can make Xingyao go further."

    "As for your 10 billion investment, Ali is not without money, but you have to give me a reason to convince me."

    "President Ma, Du Xingyu is my younger martial brother. As long as he can invest 10 billion yuan, he will serve as the super scientific and technological consultant of Xingyao to help develop rocket and spacecraft technology!" Dong Jiangbo said, "the future of commercial rockets is here!"

    "That kid, I know, is a very capable young man." Mr. Ma smiled and said, "but it doesn''t convince me to come up with 10 billion, rocket technology. You''re too far behind..."

    Dong Jiangbo''s negotiation with Mr. Ma was not smooth. In the final analysis, Mr. Ma was only willing to invest one billion, and some other funds and investors were similar.

    Dong Jiangbo went to see several other domestic giant companies, such as penguin and Huawei, but the replies were almost the same.

    They are willing to invest some money. If they want to spend 10 billion, these enterprises are not willing. The reason is very simple. The strength of Xingyao rocket is too weak, and these large companies do not pay much attention to the commercial benefits brought by space exploration.

    "It''s hard!" Dong Jiangbo said with emotion when chatting with Du Xingyu Weixin. "I''ve run many investment institutions. If I really want to calculate, it''s a little difficult to get an investment of 2.3 billion, 10 billion."

    Du Xingyu replied: "elder martial brother, they underestimated the development speed of space technology. If they knew that human beings would soon be able to enter space activities, they wouldn''t think so."

    Dong Jiangbo said reluctantly, "no wonder they don''t believe it, or our Xingyao rocket is too weak. If we also have the strength of space exploration technology companies, I''m afraid these companies will rush to send money."

    Du Xingyu thought for a while and said, "senior brother, you don''t have to worry too much. Now you can take advantage of this space heat to absorb more funds and recruit talents."

    "I think in three months, I should be able to prove to them that the era of space exploration is coming!"

    "??" Dong Jiangbo said strangely, "what will happen in three months?"

    "I can''t say this for the time being. It''s a confidential task," said Du Xingyu. "In short, you''ll know in three months."

    "OK!" although Dong Jiangbo was still full of doubts, he chose to believe Du Xingyu. He said, "I''ll make good arrangements and wait for your good news in three months!"

    In the nuclear rocket research group, Du Xingyu sat in his office. He put down his mobile phone and looked at the three-dimensional design drawings on the computer.

    Two months have passed since the establishment of the nuclear powered rocket project. In these two months, relying on the scientific and technological simulator, he has completed the problems of reactor control, exhaust pollution and radiation protection. Now the most important thing is the design of the nuclear powered rocket propeller.

    On the science and technology simulator, the design progress of the propeller has been completed by 50%. He estimates that the results will be available this month.

    More than half of the rocket body has been manufactured

    "Strive to complete the design of nuclear powered rocket thrusters in half a month, manufacture and assembly in one month... Commissioning in the remaining month." Du Xingyu calculated in his heart.

    Three months later, NASA has a number of important satellites and probes to launch. Among them is the final work of the third phase of the Chinese lunar exploration project, the Chang''e 5 lunar probe.

    Before the chang''e-5 probe, the Huaxia space agency has launched Chang''e-1 to chang''e-4 probes. The functions of these probes are more and more advanced.

    The chang''e-5 probe, which has been commissioned and waiting for launch, is China''s first probe with the function of sampling on the lunar surface and returning to the earth!

    When it is launched, it will certainly attract public attention. If the nuclear powered rocket can undertake the task of launching Chang''e 5 probe, the name of the nuclear powered rocket will also be known all over the world.

    As long as he can successfully manufacture nuclear powered rockets and ensure safety, Du Xingyu is not worried that the top will not approve the test launch. Because Huaxia space agency is used to making "two hands ready", probes such as Chang''e 5 are made at one time and one is left for standby.

    For example, the last time the tianwen-1 Mars probe was launched, there is still a spare one in NASA, which is being transformed and ready to be launched as a second Mars probe.

    Du Xingyu opened the science and technology simulator and invested 100000 energy points to start the simulation design of nuclear powered rocket thrusters.

    In his mind, he is making a "high-efficiency heat exchanger", which is a device to use nuclear energy.

    The nuclear reactor under design is a nuclear fission reactor, which has a strong risk of radiation pollution. Once the heat energy cannot be controlled, it may cause an explosion!

    At that time, the nuclear powered rocket will become a small nuclear bomb! So this step is very important!

    "Successful research and development!" with the prompt of the technology simulator, the drawing of the high-efficiency heat exchanger is lit.

    Du Xingyu took a look and continued: "invest 100000 points of energy to start the simulation of turbopump components!"

    "The turbine pump assembly is being simulated. Please select the design scheme and relevant parts." in front of Du Xingyu, there are sketches of various schemes and the styles of corresponding materials and parts.
