Prince of Tang Dynasty

Although Xiao Yu has become a great Confucian of a generation, he himself is still tireless in the matter of "learning".After seeing the model of the windmill made by Li Yu, he not only aroused a strong curiosity, but also aroused a strong desire to ask questions.

Li Yu was dragged by Xiao Yu and kept asking all kinds of questions. Fortunately, he was good at science and engineering, otherwise he would be left speechless like the punctuation marks before.

Xiao Yu is a great Confucian of the generation, and what he is good at is learning.To be precise, he is good at liberal arts, not so good at science and engineering, but he is very studious.

Li Yu took the design drawing and explained it to Xiao Yu bit by bit.

Listening to Li Yu's explanation, Xiao Yu became more and more startled, but it didn't show on his face.

Li Yu didn't notice Xiao Yu's strangeness, and patiently continued to explain to Xiao Yu the structure of each part of the windmill and the function of each part.

Although Xiao Yu was not good at science and engineering, after listening to Li Yu's detailed explanation, he roughly understood the working principle of the windmill.

"This is how the windmill works." Li Yu dryly explained the operation principle of the windmill and asked, "Sir, do you understand?"

Xiao Yu stroked his beard, and replied honestly: "The old minister is confused, His Royal Highness King Rui, can you show the old minister this design drawing?"

"This blueprint is still for the craftsmen to use. Let me draw another one for you."

"His Royal Highness King Laurie is here." Xiao Yu felt that Li Yu made this windmill too powerful and very useful. "His Royal Highness, your windmill must be built in various places in the Tang Dynasty." With this windmill, the lives of ordinary people will be very convenient.

"Don't worry, sir. After we build the first windmill, it will come in handy during the autumn harvest, and we will promote the windmill at that time." Li Yu said seriously, "The structure of the windmill is relatively complicated. Let the craftsmen of the Ministry of Industry become proficient."

Lu Erli and his ten craftsmen gathered together to make the model of the windmill with great concentration.Unaware of Xiao Yu's arrival, they had a heated discussion while making models.

"His Royal Highness, can I watch you make a model of this windmill?"

"Of course." Li Yu said with a smile, "Sir, then I will continue to do it." He has only finished the lower body of the windmill, and the upper body has not yet been done.

Xiao Yu nodded and said nothing.

Just when Li Yu was about to continue working, Tuesday came over to remind him that it was time for dinner.

Li Yu had no choice but to suspend what he was doing, and went to the dining hall to have dinner first.Tonight's dinner is still very rich, and the table is basically full of big fish and meat.

During dinner, Xiao Yu continued to ask Li Yu about the windmill, and he didn't even bother to pay attention to the delicious food for dinner.

This time, Li Yu told Xiao Yu a lot about physics, as well as knowledge about Mohism mechanism and Luban technology.

This time Li Yu spoke very simple and straightforward, and Xiao Yu basically understood.After understanding, Xiao Yu was even more startled, and was even more amazed at Li Yu's talent.

His Royal Highness King Rui has such great talent at such a young age, and his talent is of great help to the Tang Dynasty. It can even be said that His Royal Highness King Rui's talent can benefit the people of Datang. No wonder His Majesty values ​​King Rui so much. Your Highness, the youngest son, let him teach His Highness King Rui strictly?

Your Majesty is right to worry, His Royal Highness King Rui's talents are indeed overkill when used in business.

After dinner, Li Yu continued to make models of windmills.

Xiao Yu sat aside, watching Li Yu's windmill model very seriously.This time, he didn't ask Li Yu any questions, but watched very quietly.

Li Zhi and Li Mingda sat across from Xiao Yu, watching Li Yu make a windmill model, and helping deliver parts to Li Yu.

Before Li Yu made the model of the windmill, he didn't make all the necessary parts first.Don't look at it as a small windmill model, but there are hundreds of parts used.It takes a lot of work to make all the parts used.Li Yu made the model of the windmill while making the parts used.Although it will take effort to do so, it is not easy to make mistakes.

Since there are no foreign nails and screws at this time, only mortise and tenon can be used to assemble the parts.When making parts, it is necessary to design the structure of mortise and tenon, so that it is easy to assemble.

Xiao Yu was shocked to see Li Yu skillfully drawing lines, carving, and punching holes on the wood.His Royal Highness King Rui is only six years old, but his skillful movements are like that of a carpenter with rich experience.

Li Yu made the model of the windmill much faster than Lu Erli and the others. Before Haishi, he had finished the model of the windmill.

When it was done, he asked them to bring some rice over on Monday for experiments.

Xiao Yu, Li Zhi and the others were stunned when they saw that the windmill made by Li Yu could really crush rice.

Li Yu also asked Zhou Yi to go to the kitchen to bring some salt, and the windmill can also crush coarse salt.

Seeing that a small piece of salt that Li Yu broke off was also crushed by the windmill, Xiao Yu and the others were shocked again.

"Xiao Yu'er, you are amazing!" Li Mingda looked at Li Yu with sparkling eyes, and his small face was full of admiration.

"Little Yu'er, you are really amazing!" Li Zhi also looked excited.

Xiao Yu was also excited when he saw it, and his blood boiled: "His Royal Highness, this windmill of yours must... be built in various places in the Tang Dynasty."

"Don't worry, sir, the windmills will be promoted in the Tang Dynasty." Li Yu stroked his chin and looked thoughtfully at the windmill he had finished.

Seeing Li Yu frowning slightly, with a thoughtful expression, Li Zhi asked with concern: "Xiao Yu'er, what's wrong with you?"

Li Yu stroked his chin and said, "I feel that this windmill can be improved." After speaking, he took a brush and began to calculate something with formulas on the paper.

Xiao Yu saw a series of symbols written by Li Yu on the paper, these symbols had never been seen before, which made him very surprised.

He really wanted to ask Li Yu what these symbols were, but seeing His Royal Highness King Rui was seriously concentrating on writing, he was too embarrassed to interrupt.

Li Zhi and Li Mingda were already used to Li Yu's "ghost drawing talisman", and when they saw Li Yu doing "ghost drawing talisman" again, they didn't make a sound to interrupt.In fact, what Li Yu wrote on the paper were some mathematical and physical formulas, and they were written in Arabic numerals, so they looked like "ghost symbols".

While Li Yu was writing and calculating on the paper, he was muttering something in a low voice.After half an hour, the result was finally calculated.

"Sure enough, it can be improved."

Xiao Yu hurriedly asked: "His Royal Highness, what can be improved?"

"The structure can be improved." After Li Yu finished speaking, he picked up a brush and drew the design of the improved windmill on the paper.

Lu Erli and his ten craftsmen are still studying and assembling the first version of the windmill, but the assembly is not very smooth.

A few hours ago, Li Yu drew the design of the improved windmill.

If the improved version of the windmill is successful, it will be much more efficient than the previous first version of the windmill.

The author has something to say: Kawen can only write [-] words, but cannot write [-] words.Can I say that this chapter is two thousand words, how many hours did I write it?
