"What''s wrong with that? It''s better to hit the sun than choose a day. It happens that these two days are the time... Or today? I happened to give myself a holiday... "Deng Lanqing was very acute. In addition, she was worried that Yun Fei would go back on his word.


    What do you think of it? How do you think it''s cheating.


    Therefore, she can''t worry until she implements it first.


    "Today? Forget it. You can''t expect anything to happen between me and you. I am a principled person... "Deng Lanqing is like this. Even if she can conceive, the children born are likely to have problems.


    "NIMA, are you crazy?" Deng Lanqing was immediately angry.


    "You don''t have to go to bed to achieve your goal, do you?" Yun Fei carefully the surrounding environment and whispered when he saw that the nearest waiters were far away from them.


    This is Li Lu''s eye liner.


    "You mean by medical artificial means?" Deng Lanqing''s face looks better. In recent years, many infertile couples abroad use this method to achieve the purpose of pregnancy. In China, some high-income groups also use this method.


    However, it is against Chinese morality and expensive. There are not many reports in this regard.


    "What else do you want? Do you have to have sex? I don''t want to be responsible for you... "Yun Fei nodded seriously.


    "Will I hold you responsible? Isn''t it just to borrow a seed from you? " Deng Lanqing was immediately angry. She doesn''t have any love or liking feelings for Yunfei, but she thinks Yunfei''s genes are good and can give birth to better offspring, so she won''t be like this.


    Instead of being passively enjoyed by men, she might as well solve her own problems by herself!


    "Go back and ask our obstetrics and Gynecology experts who are still working in aerospace hospital, and ask them if you are suitable like this. Work needs to be done, but not in exchange for good health. Adjust the work and rest time, adjust the body, and wait until the end of this breakthrough... "Yun Fei''s meaning is very clear.


    Deng Lanqing is a little older than Li Lu in terms of age. She can''t help but worry about this. How dangerous old pregnant women are is still a big problem in this era of developed medical technology.


    "Are you sure you didn''t lie to me?" Deng Lanqing was puzzled about this matter. Yunfei''s reaction was too abnormal this time.


    Yun Fei was speechless and said, "if you don''t believe me, I can write a letter of commitment. Of course, it''s only your child''s physiological father at most. In medicine, it''s called a sperm donor... "


    "In fact, we don''t have to do that. It might be better to conceive naturally..." after a long silence, Deng Lanqing blushed and said to Yu Yunfei. Although she can solve problems by herself, natural ones are far better than artificial ones.


    "Pull it down, you. It''s like this. It''s not negotiable. You can do it yourself. Of course, if you don''t agree, you can do whatever you want... "When Yun Fei heard Deng Lanqing''s words, he immediately pulled out the corners of his mouth.


    It can''t be like this under any circumstances.


    "Let''s put this aside and talk about the five axis machining center. After all, old sun is so old that I can''t pay too much attention... "Seeing Deng Lanqing, Yun Fei hurriedly changed the topic.


    Deng Lanqing, a woman, only cares about her work and having children.


    The five axis machining center has been built for so many years. Although it has been built, the accuracy is not high. If it is introduced to the market, it can only smash its own signboard, and the technology can not compete with foreign countries, it will make domestic users lose confidence in the brand of Jiuyi group.


    Over the years, Jiuyi group has been competing with foreign medium and high-end brands, and its technical parameters and performance are no worse than them. Therefore, their products can be sold more expensive than those domestic state-owned factories and foreign machine tool factories.


    This is their advantage.


    This is an illusion to domestic users.


    Their machine tool technology is not the most top-level, but from the beginning, he followed the international technical blockade against China, restricted the export of some high-performance equipment to China, and launched equipment with slightly better performance than the other side for competition. When the international market liberalizes higher-level equipment to China''s market, Yunfei''s Jiuyi group has launched a new generation of equipment no worse than them.


    For some equipment with super machining accuracy, such as CNC grinding center, super military precision machine tools with machining accuracy of 0.001mm or even more, it is impossible to sell to the Chinese no matter how the technology of China''s domestic machine tool industry develops. Those equipment are not easy to produce abroad. The production time span of many equipment is very large.


    If they now open the top CNC machine tools of this military aircraft to the Chinese market, there is absolutely no possibility that Jiuyi heavy industry can compete with them in this top field in a short time.


    Those machine tool factories abroad do not know this.


    However, once such equipment is exported to China, various related industries of Chinese people will spring up like mushrooms. This is the result that the whole western world cannot bear.


    Advanced machine tool technology is not only more advanced than the Chinese in technology, but also some design concepts. These concepts are a layer of window paper. Once pierced, many related industries can use this design concept.


    China is the same as the former Soviet Union, not lack of technology, but lack of advanced design concepts. Just like some major projects in China that frightened foreigners. For example, most of these two bombs and one satellite were presided over by Chinese technical experts who came back from Europe and the United States. Without any foundation, they were developed in just a few years.


    Now, even if China has a foundation, the development of various high-end technology industries in China is limited because of the technological fault caused by the ten-year great turmoil and the pressure from abroad, as well as the comprador idea of the Qing Empire, which has been declining for nearly a century.


    CNC machine tools are basically the basis of the whole industry and can be listed as the same strategic position as materials.


    If China wants to rise, it must make a breakthrough in this technology.


    Only when this technology breaks through can the manufacturing industry as a whole make a breakthrough. This is a key link.


    If Yunfei wants China''s already backward machine tool industry to rise, he must build confidence for the Chinese people. Let them think that China''s technology is no worse than that of foreign countries.


    This has created an illusion - the technology of Jiuyi heavy industry in CNC machine tools can fully compete with the top international brands. Moreover, their strategy has always been successful.


    "You know this project better than I do. Although our structure has been worked out and there are no problems with the function, it is the most difficult to improve the accuracy. Only by constantly experimenting and then modifying the design... "Deng Lanqing sighed.


    If Yun wants to get the time before May Day, he must make more experiments than before in just a few months. Produce more prototypes.


    In other words, it was hit with money.


    The improvement of accuracy lies in the design concept and manufacturing accuracy level.


    Anyway, when we haven''t invested in the project of large aircraft, we don''t care about this money at all because of the large-scale capital return at the end of the year. In addition to the quarterly financial budget, 200 million research funds have been allocated to this project.


    He just wants to use money to smash out this technology.


    Two hundred million, for the five axis CNC machining center with high profits, the cost can be recovered in less than a few units.


    Now, once the No. 20 project of 132 starts the sample manufacturing and the large aircraft project starts, the domestic sales will be absolutely indispensable.


    Want to get orders from commercial aircraft companies not controlled by cloud? Yes, do you have the processing capacity? what? Can four axes ensure the machining accuracy of some complex structural parts? Don''t be kidding. It''s useless without five axes.


    Do you have the five axis machining center you bought from the devil? Hehe, are your technicians proficient in Japanese? What if there are problems in the processing process that affect our accuracy?


    In this way, those who want to support large aircraft projects, even if the demand for five axis machining center is not urgent, they must buy five axes from 91 heavy industry.


    This is why Yunfei uses its outsourcing orders to kidnap consumers'' purchase intention.


    Just like the machinery processing plants supporting them and the machinery outsourcing plants supporting xinkaixing and other companies, all of them use the series of CNC machine tools produced by Jiuyi heavy industry.


    Whether in China or abroad, this means of sales is essential.


    Of course, if abroad, this is likely to be cleaned up by the anti-monopoly law. In China, at least for now, it is impossible.


    "I also know that it''s not enough to smash with money. It will take time. You don''t have to get it out in May. At that time, as long as the accuracy level can be improved to within the range of 0.012, the problem is not too big. The range of 0.005 is too difficult for us... "Yun Fei is very painful.


    The most depressing thing about him is that the time he came to this world is too short.


    If we had come to this world earlier, many things would not have been like this.


    Even two years in the morning, he can get more real technical experts back from the scientific research institutes of the former Soviet Union. At least not cheap in Europe and America. The treatment given to them by Europe and America is not as good as that given by him.


    "You know? I thought you didn''t know! " When Deng Lanqing said this, he was angry with Yunfei.


    Yun Fei stared at her: "I can''t do it. Don''t you know?"


    "Now that you know, why do you release such a task when it is basically impossible? Don''t you think you can smash this technology with money? "
