Song Yingxing was a knowledgeable, diligent and technical scholar with a strong spirit of study. If such a person was in a society where the imperial examination system was the dominant society, his achievements would be limited. For example, during the Chongzhen Dynasty, he could only summarize the experience of his predecessors and compile a book called "The Creation of Things in Heaven", and then, there would be nothing more.

Of course, it is not to say that "The Creation of Things in Heaven" is an indescribable miscellaneous book. On the contrary, "The Creation of Things in Heaven" is a rare scientific masterpiece. It has made indelible contributions to the inheritance and promotion of ancient technology. It is known as the "17th century Craft Encyclopedia". His influence even surpassed national boundaries and played an important role in promoting the development of science and technology in the entire modern era.

He can achieve such great achievements in such a difficult environment. So what achievements will he achieve in the Chongzheng Dynasty and Zhu Cijiu's attention and appreciation?

This achievement is still incalculable. At least Zhu Cijiong believes that tool steel, silicon steel sheets, and gear steel will be developed soon by him, because smelting technology is his strength!

After solving the problem of alloy materials, we can start the research on the power source and transmission device.

These two aspects are not very complicated, and the talents are also ready-made. Zhu Cijing directly recruited Bi Maokang, Wang Zheng, Xu Fuyuan and Xia Yunyi to the study room, preparing to explain both aspects at once.

These four people are also the confidants of Zhu Cijing's confidants, and the king and his ministers were completely ignored. After the king and his ministers met, Bi Maokang, Wang Zheng and others would also congratulate him like Song Yingxing. It seems that the queen is happy and it is really a major event for the country.

Unexpectedly, after congratulations, they still had something to say. After Zhu Cijiu asked everyone to sit down, he was about to start explaining the precision machine tool. Bi Maokang bowed with courage: "Your Majesty, please forgive me and ask, what happened to Changgeng, suddenly he resigned from the position of the Ministry of Works and the Qing Office Department. Now, even the figures are gone!"

After all, he was a colleague for many years and a close confidant of the emperor. Bi Maokang and Song Yingxing had a good relationship. Now Song Yingxing left the Ministry of Works silently. Even the emperor convened a meeting with the Ministry of Works officials but did not see him. He said he was not worried, that was fake.

Bi Maokang even thought that Song Yingxing had offended the emperor, so he disappeared. Otherwise, as his confidant, who would dare to touch him? So he wanted to ask the reason and say a few good words to him in front of the emperor to see if he could get him back to his post.

When Zhu Cijing saw Bi Maokang's worried look, he couldn't help but slapped his forehead. Song Yingxing was too crazy. As soon as there was a research project, he immediately forgot everything. He estimated that Song Yingxing should have forgotten to fight Bi Maokang because of his greetings, and immediately summoned people to go to Huguang to find the sylvanothermite!

This guy, Zhu Cijiong smiled bitterly and said, "It's nothing. I asked him to develop alloy materials. Didn't he even say hello to you?"

When Bi Maokang heard this, he let out a long sigh and said fortunately: "It's fine, it's fine. I thought something had happened to him. Since it was the emperor who asked him to do things, he should do it immediately, without saying hello to me or say hello to me."

Zhu Cijiu shook his head and said helplessly: "This Chang Geng is so obsessed with technical research. It is not easy to get a Jinshi exam. Now, I can't even get promoted even if I want to promote him. People are afraid of it!"

Bi Maokang sighed and said, "Yes, it's really a pity. His contribution to the Ming Dynasty far exceeds that of us. He just lacks such a fame. He should be the Minister of Works. He is ashamed, ashamed."

Zhu Cijing quickly waved his hand to comfort him: "Meng Hou, don't belittle himself. Chang Geng himself said that he is not suitable to be in the officialdom. If a person like him who is crazy about technology is the Minister of Works, he may be able to study something at any time. By then, he will definitely ignore everything. Wouldn't I have a headache! Everyone has their own ambitions, let him go."

Bi Maokang remembered Song Yingxing's enthusiasm for studying, and couldn't help but smile and nodded, "Yes, Changgeng is good at everything, but he is too obsessed with studying technology. He wants to be obsessed with it. Not to mention paying attention to others, he can't even control himself. For example, when the train was developed, his disciples ran to me and asked me to call him for dinner. This guy didn't want to eat after studying. He was not the old guys, but the others couldn't pull him!"

Zhu Cijiong smiled and shook his head and said, "Okay, let's not talk about him anymore. I'm asking you for this time, but it's actually related to the things he developed. How do you think the machine tools in the Ming Dynasty are like now?"

When Bi Maokang heard this, he did not answer, but looked at Wang Zheng. After all, Wang Zheng is an expert in mechanical aspects.

When Wang Zheng saw Bi Maokang's eyes, he immediately bowed and said, "Go back to the emperor, please forgive me for being brave. After so many years of use, I feel that many places of these machine tools need to be improved."

Zhu Cijiu said with great interest: "Oh, what are the specific aspects? Tell me."

Wang Zheng thought about it and gave an example: "For example, gears usually need to be replaced in less than a year. The wear is too serious and it will jump around if it is not replaced, and it is impossible to use it. Also, Weichen thinks this should be a problem of the material. The fixing of gears also needs to be improved. Weichen feels that it cannot be fixed with two steel plates at all, loose and heavier the wear."

Zhu Cijing nodded with relief and said, "Well, you are right. This time I want to make comprehensive improvements to the machine tool to solve these problems."

Upon hearing this, Wang Zheng immediately asked excitedly: "Master, do you mean that all these problems can be solved?"

Zhu Cijing nodded without hesitation and said, "Yes, the problem you mentioned is actually very easy to solve. Chang Geng will make a kind of gear-specific steel this time, which is very wear-resistant and will be fine for several years. As for the fixing problem, you said, if you cast a shell and wrap the gears completely, just fix the shell to the ground at that time."

Wang Zheng thought about it and couldn't help but praise: "The emperor is wise, if this is the case, the gear problem will be solved."

Zhu Cijing then picked up the brush on the table and started drawing it on the paper. While drawing, he explained: "Also, gear transmission does not necessarily only have two gears of size. For example, a turbine and a worm can still be transmitted. I gave him a name, called the worm gear and worm gearbox; and, like this, make a circular shell, process a circle of teeth on the inner surface, then install three pinions, and then install a toothed shaft in the middle, so that it can also be transmitted. I gave him a name, called the planetary reducer."

Wang Zheng nodded while looking at the drawings. He clearly understood it, but after Zhu Cijiu finished drawing, he immediately asked in surprise: "Prince, why should you slow down? Aren't it all acceleration now?"

Zhu Cijing slapped his forehead and explained: "In the future, no steam piston is needed, but it is changed to a motor. The motor is directly equipped with a rotating shaft. It rotates much more steadily than the steam piston set, and the speed is very fast, so it needs to slow down."

After he said that, he looked up and saw that everyone looked confused. Well, what is this motor? I haven't explained to them yet!
