My Daming New Empire

So this little thing attracted most people's discussion. Seeing that Zhu Zhanji came back with Ma Zhicai, everyone greeted Zhu Zhanji according to their official positions.

At this time, Ma Zhicai was the most excited. The big man in the government office that he could only look up to, now treats him differently because he is following Zhu Zhanji.

Wu Zhong seemed to be impatient. After Zhu Zhanji bowed to everyone, he couldn't wait to ask: "Your Highness, the bearing is beneficial to the country and the people, but I think it is complicated to make. Not only the steel ball needs to be round, It is even more difficult to grind the card groove inside and outside the steel ring, and it is not easy to mass-produce it, right?"

Chapter 91 Patents

Zhu Zhanji nodded with a smile and said, "Grinding was not easy at first, but now with this machine tool, it becomes much easier. This thing was made by Deputy Ma, let's listen to his explanation."

Ma Zhicai was so excited that he couldn't speak well, he cupped his hands with everyone and said, "I can make this thing thanks to His Highness's guidance. Without His Highness's whimsical idea, I wouldn't have thought of coming here."

Song Li stroked his beard and said with a smile, "I never thought that our Ministry of Industry still has such a great talent, but His Highness took advantage of it."

Zhu Zhanji laughed and said: "Deputy Ma Suo is still under the Ministry of Industry. Song Shangshu's words are wrong. Besides, they are both working for the Ming Dynasty, so there is no need to care which department they belong to. As long as the Ministry of Industry needs it, Deputy Ma Suo can return at any time." The work of the Ministry of Industry."

The Chinese said so, but no one dared to rob the grandson of the people he valued. Everyone praised Zhu Zhanji for his insight into talents, and after a long time of politeness, they came to see Ma Zhicai perform for everyone.

A strong bodyguard pedaled the pedal, and the clamp at one end of the machine tool quickly rotated, and the clamp at the other end clamped a grindstone, and it protruded through the round hole in the middle.

After Ma Zhi had adjusted the angle, he gently turned the swing lever. The millstone rubbed sparks on the iron ring, and made a harsh friction sound, but a groove was visible to the naked eye.

As for the groove of the inner ring, it is even simpler. You only need to change a clamp that is clamped from the inside, and a groove is directly ground from the outside.

However, because the grinding stone wears out quickly, Ma Zhicai needs to adjust the angle at any time, which requires rich experience.

In any case, this is much faster than filing with a file by one person, and it can be directly shaped.

The most troublesome thing now is the grinding of steel balls. There is really no good technology to solve this problem.

Most of today's steel balls are molten iron or steel, which is blown into the air with water and then dropped into the water to solidify directly, so that iron balls of different sizes can be formed, and then polished and quenched.

The water row is an ancient automatic blower, which uses water power to automatically compress air and send the air into the iron smelting furnace to increase the furnace temperature and melt the molten iron.

Zhu Zhanji had never known this kind of tool before, and it was only after he came to the Ming Dynasty that he realized that such an advanced blower had already existed in the Western Han Dynasty.

However, the iron balls produced in this way are of different sizes, and it is difficult to select suitable steel balls.

Therefore, there is another way, one is casting mold, which is to make a circle with a clay mold, and then pour molten iron into it.The other is to cut it with wire and polish it a little bit, which takes countless time and manpower.

After watching Ma Zhicai's demonstration, and seeing with their own eyes that two people, one pulling and one pushing, can pull a [-]-stone bullock cart, they no longer have any doubts about the role of bearings.

Wu Zhong looked at the machine tool and asked, "Can Your Highness allow the Ministry of Industry to prevent this machine tool and promote it throughout the world?"

Zhu Zhanji nodded and said, "Of course, but I have one condition."

"Please clarify, Your Highness."

"Every time the Ministry of Industry produces a machine tool like this, it must pay my mechanical research institute a patent fee of [-] yuan for the machine tool."

The cost of a machine tool is about 50 taels of silver, and the main cost lies in the cost of steel and grinding of gears.Zhu Zhanji asked for a 5.00% patent fee, which is equivalent to only two and a half silver.This little money is dispensable to him, but he wants to establish this system from now on.

Everyone was dumbfounded, looking at Zhu Zhanji speechless.Although the money is not much, it doesn't make sense for them to do things for Daming, which is equivalent to doing things for the Zhu family, and they also need to give money to Zhu Zhanji.

Moreover, Zhu Zhanji proposed a patent fee, which made it difficult for everyone to understand.

Song Li asked softly: "Your Highness, what is a patent fee?"

Zhu Zhanji said with a smile: "This is not a place to talk, we might as well move to the school, let me invite you to drink tea and explain."

When he said this, of course everyone had no objection, and Zhu Zhanji took him into an empty classroom.

Those young soldiers who had no class, including Ma Zhide, also gathered outside the classroom, wanting to hear what Zhu Zhanji, the grandson, would say to the adults.

Ma Di was the most impatient at this time. If his mother and sister were not around, he might be the first to run over.

But now his skirt is being pulled by his sister, and he loves her the most, and he can't bear to leave her alone.

"My dear sister, it's rare for His Highness to give lectures, and every time I give a lecture, I am enlightened. What's more, there are so many adults here today, let me go and listen to what they are saying."

"The elder brother will tell me when he hears it..."

"Sure, sure, I still have to tell you a lot about the grandson. You will become the grandson's concubine in the future!"

Ma Xin was embarrassed, and turned around to act like a baby with her mother. "Mother, brother laughed at me..."

Madam Ma sighed and said: "From now on, you have to be more disciplined. When you enter the royal family, you can't do anything according to your temper!"

A classroom can accommodate 40 people, and there are less than [-] officials from the Ministry of Industry who came here today. They occupy the front row, and the back is half empty.

A few brave young soldiers slipped into the classroom, and Zhu Zhanji, who was sitting in front of the podium, ignored him, and the seats behind were crowded in a short while.

But they also knew the importance, everyone stood, and no one dared to sit down.

After the waiter served them hot tea, Zhu Zhanji also took a sip from the cup in front of him and said: "Today, I have gathered with all the important ministers of the country. There is only one question I want to discuss with you adults. That is my For thousands of years in China, why did various new inventions appear in the Spring and Autumn Period, but then went from bad to worse for more than 1000 years? In the past 1000 years, why has our use of tools progressed so slowly, or even regressed? In the Qin Dynasty During the emperor's time, they were able to build Qin Zhidao with new technology, but today, we can't build it?

The reason why human beings are different from animals and livestock is that we understand etiquette, know shame, and the most important point is that we know how to use tools.During the period of the Three Emperors and Five Emperors, humans have learned to forge, but until today, we are still using the technology thousands of years ago.Of course, the method of use is improving, but in essence, there is no major change.What caused this result? "

Everyone knew that they knew Zhu Zhanji's introduction, so everyone showed a thoughtful expression, but no one answered.

Zhu Zhanji added: "Before the Qin Emperor, we learned to forge gold and silver, forged bronze, and learned to forge iron. But over the past 1000 years, are we really making progress? Why did Li Bing The Dujiangyan can be built, but today, the Yellow River and the Huaihe River are still rampant?"

"From words to theories, what we are learning now is still from that era. Could it be that the people of these thousand and five hundred years are stupider than the ancients? No, I have never thought so. Every later person is equivalent to standing on the ground. on the shoulders of the predecessors, but what caused all this?"

Zhu Zhanji took a deep breath, adjusted his breath and said: "Since I was a child, I like to read many books in the scripture library. I can't put it down when my grandfather edited the Yongle Canon. When I see those books, I always Admiring the wisdom of the ancients, I also have doubts about the development of the current backwater. If I want to change all this, I must find an answer. Today, I am here with you, and I only wish to express some of my humble opinions. I also hope that you will not blame the boy for his ignorance and lack of knowledge, making you laugh and generous, please be polite."

Song Li, who was the oldest, stood up and said with a long bow: "Learning without thinking is useless. Your Highness has such a heart of seeking truth. It is indeed a blessing to Ming Dynasty and a blessing to the world."

Zhu Zhanji returned the salute and said: "Song Shangshu is too famous, the boy is naughty, and he has never heard of Jingyan since last year."

Song Li said with a smile: "His Royal Highness has not left the cabinet yet, so it's fine if you don't participate in the sutra feast. Kind thoughts lead to quick actions. It is enough for His Highness to have a heart to seek knowledge."

This is not complete flattery, because although Song Li heard some rumors that his grandson Xiaozu was not like his father and did not like Confucianism.

But whether it is Hu Guang or Xie Jin, they have always had a high evaluation of the grandson. No matter when, they have never said that the grandson is not good at all.

If Taisun really didn't like Confucianism, I'm afraid these two would have given up on it long ago.

Today's visit to Taisun is certainly to comply with the emperor's will and to cooperate with Taisun's plan, but he does have a tempting heart.

But they didn't expect that Taisun gave them such a big shock from the very beginning.

Being able to discuss the present through the past is not something ordinary students can do.If you can't accumulate a lot of money, you will definitely make a fool of yourself in front of them.

However, although Taisun's opening remarks were indeed a little blunt, the meaning of the words was complete, the meaning was clear, and the topic was thought-provoking. This is not something ordinary students can do.

He looked at his colleagues, and they all looked happy, listening to their conversation.Seeing that no one wanted to speak, Song Li said again: "The interpretation of the word patent has aroused the grandson's emotion. Please forgive me for being negligent. Please ask someone to bring a pen and paper. Write it down."

Zhu Zhanji had no choice but to wink, and Li Liang immediately arranged for several inner eunuchs to bring pens and paper.In addition to preparing four sets of pens, inks, papers and inkstones for them.There are also four internal eunuchs who cooperate with habits to write down Zhu Zhanji's words.
