Hanlin Academy, formerly known as the Juxian Hall established by Zhu Yuanzhang.

It aims to recruit talents from all over the world and fight for King Wu at that time, also known as Lixian Hall. Later, after Zhu Yuanzhang won the world, it was changed to the Hanlin Academy, which was responsible for the compilation of historical books and the drafting of edicts for the imperial examination.

Gathered in it is a group of elites among the world's people - scholars.

Yan Shenggong, the descendant of Cheng Zhu, is obeyed and admired by the world's scholars. Therefore, as soon as they came to Yingtianfu, the officials of the Hanlin Academy handed over the prayer posts one after another and went to pay their respects.

and quietly sent gold and silver, twenty-eight beauties, literary girls.

Those with low status in the literary world are not qualified to meet them.

After that, without the emperor's will, the celebrities in the literary world respectfully invited them to the Hanlin Academy.

When they arrived at the Hanlin Academy, the three of them were high, looking like masters outside the world, pointing to the world's scholars in the Hanlin Academy.

The officials of the Hanlin Academy, on the other hand, listened respectfully to their teachings like well-behaved students.

Cheng Yi's descendant Cheng Leshan and Zhu Xi's descendant Zhu Yuandian, both of whom are old men in their sixties, are also elegant and elegant, and they are all upright and upright. Mixed in the court uniforms, among the officials of the Hanlin Academy, stand out from the crowd.

"Ministers, see the emperor!" When the officials of the Hanlin Academy saw that the emperor had arrived, they immediately knelt down to pay respects.

And Zhu Yuandian and Cheng Leshan stood up but did not worship.

When they saw Zhu Yuanzhang coming to see them in person, they knew that Yan Shenggong had already moved him.

And the three of them came to teach the emperor the art of controlling the people, and they were his teachers.

Where in the world is there a teacher who worships his students?

And if they also worship, wouldn't they be the same as those who were officials in the court, vulgar scholars? They are all hermits and masters who do not disdain to enter the ranks at all, disdain to be in the same stream as ordinary people, and are high-ranking hermits and masters.

"You two are Cheng Zhu's descendants?" However, Zhu Yuanzhang was not angry at all. With what he had experienced before, how could the two of them make him angry if they didn't salute? He asked.

"Wait, I've seen the emperor."

Cheng Leshan and Zhu Yuandian only bowed their hands slightly to the emperor.

They all claimed to be vassals rather than grass people, because they were all knights.

A descendant of Cheng Zhu, a hereditary doctor of the Five Classics.

However, they are all the same as Yan Shenggong, they only have titles, and they are generally not allowed to participate in court politics.

"We know your intentions, and we are also willing to ask the three great Confucians for advice on how to govern the country." Zhu Yuanzhang said, "However, before asking the three of you for advice, you still have to go with us to meet someone." ”

He waved his hand and said in a calm tone: "Let's go." ”

What's going on? Cheng Leshan and Zhu Yuandian looked at Yan Shenggong with inquiring eyes.

"The emperor wants the three of us to go to Lujia Village to meet that person and debate and duel with that person face to face." Yan Shenggong whispered.

"I see!" When Zhu Yuandian and Cheng Leshan heard this, their faces showed joy.

The three of them are close to 200 years old, and they have a family history, so they can't handle a child in his twenties who has not dried up?

Today, we will knock you into the dust, and you will never recover! The three of them thought to themselves.

Lujia Village.

In elementary school.

Qin Yu is still busy in the classroom, teaching students physical chemistry knowledge. "Ladies and gentlemen, have you mastered the principles of mechanical motion?" Qin Yu asked, "Mechanical motion is a very practical knowledge of physics. ”

"It is reflected in all aspects of life, and it can be directly applied, not an empty theory."

"For example, the steam turbine we studied before needs to use various mechanical principles to convert the internal energy of steam into mechanical energy and use it to serve us."

Last time, he just taught the students to make a simple model of a steam turbine and let them understand the basic principles of the steam turbine. And these days, they are teaching them how to make large steam turbines and practical steam turbines.

And how to use steam turbines.

Gears and pulleys are added to the rotating bearings of the steam turbine to change the direction of mechanical movement.

As for the seals, because Lujiacun can't find rubber, it can't be perfectly sealed. So he used the soil method to sew chicken feathers on the hemp rope. This is how the bellows used by the villagers of Lujia Village for cooking are sealed, and the effect is very good.

"We've got it all." The students answered.

Zhu Biao, Zhu Zhang, and Zhu Chun were all very excited. After learning such useful knowledge from Mr., when they return from this weekend vacation, they will be able to make all kinds of machines in a big way.

Let Daming open a new era of the industrial revolution.

In the classrooms of Lujiacun Primary School, there is peace and harmony, and the students' curiosity is very strong.

Qin Yu didn't know that he was about to have a duel across time and space with the descendants of Yan Shenggong and Cheng Zhu.

This will be a great battle of the ages.

He duel against Confucianism, which has ruled China for thousands of years, Cheng Zhu Lixue.

The villagers of Lujia Village are also working hard in the perfume workshop and in the fields, and the crowd is full of laughter and joy.

They also had no idea that if Qin Yu was defeated in this duel, Lujia Village might be in danger of being slaughtered.

After school in the afternoon.

Qin Yu left the students at school and came to the mountain alone to see the scenery of Lujia Village.

Sitting on the slope of the hill beam, chewing grass roots in his mouth, he looks very leisurely.

Seeing that Lujiacun has changed because of himself, his heart is very satisfied. His life was saved by Lu Dazhuang, a villager of Lujia Village, and helping Lujia Village so wholeheartedly can be regarded as a return for the peach.

Moreover, it is also the responsibility of volunteer teachers to bring modern civilization to poor mountain villages.

Rewarding Lujia Village and the responsibilities of the volunteer teachers have been initially realized.

From a distance, I saw Village Chief Huang, with three old men he didn't know, walking towards him from a distance.

Out of respect for the old man, Qin Yu stood up.

Village Chief Huang is a person he is familiar with, he can get up unnecessarily, and he can get along with him as naturally as an old friend. But he didn't know the other three, and they were all sixty or seventy years old.

"I've seen you, sir." After coming to Qin Yu, Zhu Yuanzhang saluted him respectfully.

"You and I are old friends, so there's no need to bow every time." Qin Yu said with a smile.

The other three, on the other hand, were arrogant.

He looked at Qin Yu with the attitude of an elder looking at a junior, and his demeanor seemed to have hatred for him.

These three people are a bit of a bad comer! Qin Yu immediately realized that the situation was wrong. Didn't I offend them? I felt strange in my heart. Could it be another disagreement in historical scholarship?

Chief Huang obtained a lot of historical theories from me and told them, but the three of them disagreed with some of their own views.

"Lao Huang, these three are ......," Qin Yu asked.

"This is Lao Kong." Zhu Yuanzhang pointed to Yan Shenggong and introduced to Qin Yu.
