Yang Rong and the other two each have a new physics book.

"The force, as much force is given, the force will be fed back."

"A punch to the table, the greater the power, the greater the feedback."

"Bang!"

Yang Rong put down the book and saw Yang Shiqi shaking his hand and smiling bitterly.

"I actually hit the table without realizing it. It hurts!"

Yang Rong smiled and said, "Everyone knows this truth, but he didn't summarize it. Xing and Bo are indeed a talented person."

Jin Youzi frowned and said, "It's too late for us to study the scriptures hard. Who would be so bored to do this?!"

Yang Rong smiled, then looked down and read.

"Hey! When people walk, their feet first give the ground a force, and then the ground feedback, and they can use the power to move forward."

"The pressure of hitting someone with a fist is different, and the effect of the result is also different."

Yang Rong put down the book, rubbed his eyebrows and said, "This book..."

"This book is a terrible way!"

Jin Youzi said disdainfully: "What is there to study when walking? What kind of buoyancy is there? Boring!"

Yang Shiqi frowned and said, "I think it's good. Look at his set, it can basically be self-consistent. The discussion on leverage has been applied in the docks. Buoyancy can also be applied to shipbuilding. Look at its density, it can calculate the density based on the size and weight of a thing. It's really exquisite!"

Jin Youzi looked carefully and his face turned pale slowly.

"It's all about craftsmanship. Is Fang Dehua going to change his career?"

Seeing his expression a little far-fetched, Yang Rong said, "Although it is a craftsman's skill, it is a practical learning. Look at this. According to his mechanics and pulley lever above, ordinary people can create something surprising."

...

In front of the palace in the prince's palace, except for Zhu Gaochi's family, the palace maids and eunuchs were surrounded by a lot. Zhu Zhanji had already formed a pulley group, then hooked a chair with a hook, and called Wanwan to come.

The pulley set consisting of a fixed pulley and a moving pulley is not very strong. Wanwan's little hands are delicate, and she pulls the chair up while pulling the rope, but she waves tortures.

"How many pounds?" Zhu Gaochi asked.

Zhu Zhanji was explaining the practicality of this physics book. There was a solid wood frame in front of him, and a row of pulleys hung in the middle.

Wanwan's pulley set only used a fixed pulley and a moving pulley, and the row on the side was empty.

"Father, thirty-six pounds."

The weight of this big chair is very scary. Wanwan usually can't lift it, but today she pulled it up with a rope. She couldn't help but feel a little excited for a moment.

"The princess is so awesome!"

Liang Zhong smiled and stared at the person beside him with threatening eyes.

All praises to our family!

"Yes! It's hard for the slave to hold that chair, but the little princess lifted it up against a rope. It's indeed..."

What is it indeed?

The man looked at Liang Zhong with a pleading look in his eyes: Big brother, princess, golden branches and jade leaves, should we praise her for being strong? How can we get married in the future!

Liang Zhong also felt something was wrong, so he coughed dryly, just about to think about other reputations, but in a blink of an eye he saw Zhu Di.

"See Your Majesty."

"See Your Majesty."

A piece of land fell in front of the hall immediately. Zhu Di narrowed his eyes and looked at the wooden shelf and said lightly: "Get up."

Huang Yan and the eunuch were confused when they looked at the pulley group behind Zhu Di. Huang Yan whispered: "This strange and lewd skill!"

The eunuch expressionlessly said without saying anything, Huang Yan said angrily: "I also demonstrated it in front of the palace people, it is indeed..."

"Grandpa Huang, this is the labor-saving pulley set in physics. You see, Wanwan can lift this chair with a rope."

Wanwan said proudly: "Grandpa Emperor, Wanwan really mentioned it just now."

Zhu Di walked closer and took a look: "How much effort can it save?"

Zhu Zhanji pointed to the pulley and set up the pulley: "Currently, half of the effort can be saved. If you can combine more pulleys, Wanwan can lift the door."

"Oh! It's true?"

Zhu Di's previous impression of science was that it could impact Confucianism and also allowed the people to learn some means of making a living.

Zhu Zhanqi was a little afraid to respond, but Wanwan volunteered to say, "Grandpa Emperor, Wanwan is so brave! If you don't believe me, just ask the third brother to come and try it."

Zhu Di hesitated a little, worried that he would break Wanwan's hand.

But Zhu Zhanji said confidently: "Sit in the basket and let Wanwan pull you."

Zhu Di said, "Just give it a try."

So Zhu Zhanji personally hooked the rope to a string of pulleys, and finally handed the rope to Wanwan.

Zhu Zhanji sat in the bamboo basket and felt like a lamb to be slaughtered, confused and helpless.

Zhu Zhanji was about 60 kilograms. If he wanted to use a rope to pull him up with a bamboo basket, Liang Zhong asked himself that it was okay, but it was difficult to figure it out.

As for Wanwan...

In front of everyone, Wanwan put the rope in her palm and walked it around twice, then her body fell...

"Huh!"

The bamboo basket moved, and Zhu Zhan's silly looked inside, not believing that it was his sister pulling the rope.

Zhu Di's brow moved and rubbed his hands behind his back.

"Hi!"

Wanwan got up, and this time she stopped squatting, but started pulling the rope one by one.

The bamboo basket gradually rose, Wanwan mastered the trick, and couldn't help but raise her mouth and shouted, "Grandpa Emperor, do you think Wanwan is amazing?"

Zhu Di's cheeks moved slightly, and his head did not speak.

"puff!"

Wanwan was so excited that she didn't notice that the height of the bamboo basket was already...

"Ouch!"

"puff!"

Zhu Zhanqiu dazed to hit the wooden pillar on the top, and when the bamboo basket flipped over, the person fell to the ground.

The Crown Princess couldn't help laughing when she saw it, but Wanwan pulled it hard, but she pulled it all over, leaning against the rope to not fall.

"Ha ha ha ha!"

Wanwan's scared look made Zhu Di laugh and laughed rare.

Zhu Zhanji clapped his hands, and Jia Quan brought the man with him and carried a large iron block over.

"Grandpa Emperor, this iron piece weighs more than 300 kilograms. We can use this pulley set and pull it up by one person."

In fact, there was no need to try it, Zhu Di believed it. He slighted his head and then squinted his eyes, but his eyes were a little dissipated.

This is a real practical learning, and it is not inferior to the Mohist school, no! The Mohist school is far from comparable!

This is what the people can learn. If the people of the Ming Dynasty learned mathematics and physics, what would the Ming Dynasty become?

The iron block had been hooked, and Jia Quan went to draw the rope himself.

Zhu Di took absent-mindedly, saw the iron ore being shaking and pulled, and then fell into deep thought.

The people should be simple, which is the judgment of the rulers for the past years and the unanimous requirement of mainstream society.

What will the people think after learning these things? What plans will they have for their future?

The most important thing is, how will they view this emperor!?

A sharp light flashed in Zhu Di's eyes.

"Grandpa Emperor, Wanwan also wants to make one!"

The iron block has reached its highest level. Jia Quan is not popular, he is not angry, and he is particularly strong when he looks.

Zhu Zhanji smiled and said, "This is very simple, it just needs to be calculated. After learning these things, the people of the Ming Dynasty will be better than those foreign races wherever they go."

Zhu Di's eyes moved slightly: Yes, the people of the Ming Dynasty must be better than foreign races, otherwise how could they beat those literati after I went there?

After fully understanding the nature of those gentlemen, Zhu Di was already desperate for most literati and civil servants.

If we follow the normal trajectory, the future of the Ming Dynasty will not be different from that of the Tang and Song dynasties, but the time of destruction is different.

"What awesome thing!"

When the eunuch saw Jia Quan easily putting down the iron block, he couldn't help but exclaim.

Huang Yan said angrily: "It's just some strange and lewd skills. Can the Ming Dynasty be turned upside down?"
