The disgraced official I took care of was actually Zhu Houcong's childhood friend.

Chapter 582

Instead of laying railways later.

In this way, efficiency will be increased by a great deal.

However, Hai Rui also understood that it would be difficult to make the old man in front of him understand how a train works.

The others looked at Yang Shengzhai with envy, whose background was something they could only dream of.

"Greetings, Prime Minister."

Hai Rui and the others bowed in greeting.

"No need for formalities. I would like to see the blueprints for the train. Is that alright?"

When facing Hai Rui and others, Yang Yiqing did not refer to himself as "this official." In his eyes, these were all his grandson's colleagues and friends, so Yang Yiqing naturally did not put on airs.

"Naturally."

As Hai Rui spoke, he took the train blueprints spread out on the table in front of him and placed them in front of Yang Yiqing.

"This is the train blueprint drawn by the teacher. However, the teacher said that he only drew a rough sketch, which was based on his idea. Many parts of it are not correct."

Hai Rui handed the blueprints to Yang Yiqing while explaining.

Yang Yiqing took the blueprints and looked at the three-dimensional structure diagrams on them. He was immediately overwhelmed and couldn't understand them at all.

At this moment, he shared the same thoughts as Jiajing.

What is Zhou Hengqi's brain made of? Is he some kind of celestial being descended to earth? How does he know everything?

However, Yang Yiqing didn't have time to think about this problem at the moment; he first needed to figure out what the drawing was about.

"I don't quite understand these blueprints."

Yang Yiqing looked at his grandson and Hai Rui and the others, and said with some embarrassment.

"This is the 3D view that our teacher taught us, showing the specific appearance of the train. We've also drawn it in the last two days."

As Yang Shengzhai spoke, he took another drawing from the bookshelf next to him. It was a train drawing made using a plan view.

With the two drawings corroborating each other, and with Yang Shengzhai and Hai Rui providing explanations, Yang Yiqing finally understood what the three-dimensional model of the train looked like.

The steam engine we just saw is going to be put inside the train as its power system. How big must that train be?

"Could a steam engine really move such a heavy train?"

Yang Yiqing was somewhat skeptical.

"Yes, it's possible. With the rails in place, the coefficient of friction between the train wheels and the rails is very small. Once the steam engine starts running, the train will gradually accelerate. After reaching a certain speed, the train will move at a constant speed. The energy required for constant speed movement is very small; it only needs to overcome the friction between the wheels and the rails."

Hai Rui then gave a serious explanation.

Yang Yiqing didn't understand a single word, and his head was spinning, but that didn't stop him from understanding that the steam engine could indeed power the steel behemoth that was the train.

This is enough.

"Although I still don't quite understand, seeing how confident you are, I get it. May I take this drawing with me so I can explain it to my colleagues?"

Yang Yiqing pointed to the plan view of the train drawn by Hai Rui and others and said.

Upon hearing this, Hai Rui and the others nodded in agreement. This drawing was merely something they had created on a whim, and they had no real need for it, as they had long since learned how to read three-dimensional drawings.

"Shengzhai, you're busy, you don't need to see me off."

Yang Yiqing picked up the blueprints and looked at Yang Shengzhai.

Yang Shengzhai glanced at his grandfather before turning back to continue discussing the drive shaft with Hai Rui.

Yang Shengzhai glanced back at his grandson's serious and busy figure, feeling extremely gratified.

He had a premonition that the Ming Dynasty would undergo a major transformation under the leadership of his grandsons and others.

Thinking of this, Yang Yiqing's steps became lighter.

On his way back to Wenyuan Pavilion, he had already planned how to boast to his colleagues that the train was designed by his grandson and others.

"My lord, what did His Majesty say?"
