Song Yingxing is an erudite, diligent, and technical scholar with a strong spirit of study, if this kind of person is placed in the society where the imperial examination system is in power, the achievements that can be achieved are limited, like the Chongzhen Dynasty, he can only summarize the experience of his predecessors, and compile a book of "Heavenly Works", and then, there is no then.

Of course, it is not that "Tiangong Kaiwu" is a miscellaneous book that is not worth mentioning, on the contrary, "Tiangong Kaiwu" is a rare scientific masterpiece, he has made an indelible contribution to the inheritance and promotion of ancient technology, known as "the encyclopedia of craftsmanship in the 17th century", his influence even transcends national borders, and plays an important role in promoting the development of science and technology throughout modern times.

In such a difficult environment, he can achieve such great achievements, so in the Chongzheng Dynasty, under Zhu Cijiong's attention and appreciation, what kind of achievements will he achieve?

This achievement is still immeasurable, at least Zhu Cijiong believes that tool steel, silicon steel sheet, and gear steel will soon be developed by him, because smelting technology is his strength!

After solving the problem of alloy materials, the next step is to start the research of power sources and transmissions.

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

These four people are also the cronies of Zhu Cijiong's cronies, and there is no difference between the monarch and the minister, after the monarch and the minister see the ceremony, Bi Maokang and Wang Zheng and others also congratulate Song Yingxing, it seems that the queen is really a major event of the country.

Unexpectedly, after congratulating them, they still had something to say, after Zhu Cijiong asked everyone to sit down, he was about to start explaining the matter of the precision machine tool, but Bi Maokang was bold and said: "Your Majesty, please forgive Weichen for daring to ask, what happened to Chang Geng, suddenly resigned from the position of the Ministry of Works, and now, even the figure is gone!" “

After all, they have been colleagues for many years, and they are both cronies of the emperor, the relationship between Bi Maokang and Song Yingxing is still quite good, and now Song Yingxing has left the Ministry of Industry silently, and even the emperor has called a meeting of the officials of the Ministry of Industry without seeing him, saying that he is not worried, it is false.

Bi Maokang even thought that Song Yingxing had offended the emperor, so he disappeared, otherwise with his identity as the emperor's cronies, who would dare to touch him, so he also wanted to ask the reason and say a few good words for him in front of the emperor to see if he could be reinstated.

Zhu Cijiong saw Bi Maokang's worried look, and couldn't help but pat his forehead, this Song Yingxing is too crazy, as soon as there is a research project, he immediately forgot everything, he estimated that Song Yingxing should have forgotten to say hello and Bi Maokang, and immediately summoned people to go to Huguang to find scheelite ore!

This guy, Zhu Cijiong smiled bitterly: "It's nothing, I asked him to develop alloy materials, didn't he even say hello to you?" “

When Bi Maokang heard this, he breathed a sigh of relief, and said happily: "It's okay, it's okay, Weichen still thinks something happened to him, since the emperor asked him to do something, then naturally he should do it immediately, no need to say hello to me, no need to say hello to me." “

Zhu Cijiong shook his head and said helplessly: "This Chang Geng, he is too obsessed with technical research, if he can treat the imperial examination with this half of the strength, it is not easy to get a Jinshi fame, now it's okay, I can't even promote him if I want to, people are terrible!" “

Bi Maokang sighed and said: "Yes, it's really a pity, his contribution to the Ming Dynasty far exceeds ours, just the lack of such a fame, this Ministry of Works, it stands to reason that he should be the one, ashamed, ashamed." “

Zhu Cijiong hurriedly waved his hand and comforted: "Meng Hou, don't be presumptuous, Chang Geng himself has said that he is not suitable for mixing in officialdom, if a person like him who is crazy about studying technology becomes the secretary of the Ministry of Industry, he may be bored to study something at any time, and at that time he will definitely not care about anything, won't I have a headache to death!" Everyone has his own aspirations, so let him go. “

Bi Maokang remembered Song Yingxing's research energy, and couldn't help but smile and nodded: "Yes, Chang Gung is good at everything, but he is too obsessed with studying technology, he wants to be obsessed, let alone care about others, he can't control himself." For example, when the train was being developed, several times his disciples came to me and asked me to call him to eat, this guy didn't want to eat when he studied hard, it wasn't us old guys, and he couldn't pull it when others went to pull him! “

Zhu Cijiong smiled and shook his head: "Okay, let's not talk about him, I came to you this time, in fact, it is also related to the things he developed, how do you feel about the machine tool of Daming now?" “

When Bi Maokang heard this, he did not answer, but looked at Wang Zheng, after all, in terms of machinery, Wang Zheng is an expert.

Wang Zheng saw Bi Maokang's eyes, and immediately arched his hand and said: "Back to the emperor, please forgive Weichen for being courageous, after so many years of use, Weichen feels that many of these machine tools need to be improved." “

Zhu Cijiong said with interest: "Oh, what are the specific aspects? Tell me about it. “

Wang Zheng thought for a while, and said, for example: "For example, gears generally need to be replaced in less than a year, and the wear is too serious, and if they are not replaced, they will jump around, and they can't be used at all, and Weichen thinks that this should be a problem with the material." There is also the fixation of the gear that needs to be improved, and Weichen feels that it cannot be fixed at all with two steel plates, which is loose and saggy, and it is more heavy and wearable. “

Zhu Cijiong nodded with satisfaction and said: "Well, what you said is very right, I want to make a comprehensive improvement to the machine tool this time to solve these problems." “

When Wang Zheng heard this, he immediately asked excitedly: "Your Majesty, are you saying that there are ways to solve these problems?" “

Zhu Cijiong nodded without hesitation and said: "Yes, the problem you said is actually very easy to solve, Chang Gung will make a special steel for gears this time, which is very wear-resistant, and it is no problem to use it for a few years, as for the fixing problem, you said, if you cast a shell, how about completely wrapping the gears, and then you just need to fix the shell on the ground." “

Wang Zheng thought about it and couldn't help but praise: "The emperor is wise, in this way, the problem of gears will be solved." “

Zhu Cijiong then picked up the brush on the table and began to draw on the paper, explaining while drawing: "Also, gear transmission is not necessarily only two gears, such as this, a turbine, a worm, can still be transmitted, I gave him a name, called worm gear and worm reducer; Also, like this, make a round shell, process a circle of teeth on the inside, and then install three pinions, and then install a toothed shaft in the middle, so that it can also be transmitted, and I gave him a name, called the planetary reducer. “

Wang Zheng nodded while looking at the drawings, like that, he clearly understood, but after Zhu Cijiong finished drawing, he immediately asked in surprise: "Your Majesty, why do you want to slow down, isn't it all speeding up now?" “

Zhu Cijiong slapped his forehead and explained: "In the future, there will be no steam piston, change to a motor, the motor is directly with a rotating shaft, which is much more stable than the steam piston, and the speed is very fast, so you have to slow down." “

After he finished speaking, he looked up, and everyone looked confused, okay, what is this motor has not been explained to them!
