Seeing everyone's surprised expressions, Ying Feiyu thought to himself: If you could think of everything, nothing would have happened to him today!

"Playing while learning and learning through play are the best ways to improve the quality of education. It is much better than just memorizing by rote!"

"It's true! Your Highness, what you said makes so much sense!"

The veterans of the Ministry of Education who had just been re-employed all had wrinkles on their faces, but at this time they showed great surprise and admiration.

"snort!"

Like them, Ying Zheng also felt that it was reasonable, but at this time, the round earth theory had not yet been resolved, so he still had a sullen face, pretending to be angry, and snorted coldly from time to time.

In just a moment, the waiter returned with a few people and something in his hands!

"Huh? Your Highness, the sun is high now. Why did you tell them to bring the oil lamp?"

Feng Quji looked at what the chamberlain brought back and was very puzzled.

In addition to the oil lamps, there are also several goose eggs and chicken eggs. I don’t know what they are for!

"You guys are planning to open fire here and get a few of us fired?"

Ying Zheng glanced at it and mocked.

"Father, just watch...!"

Ying Feiyu smiled indifferently and did not explain too much. He just waved his hand towards the servant and said, "Cover all the windows!"

"yes!"

The little maids have been ordered to do it quickly.

After a while, the light in the room became dim!

Since it was noon at this time, the sun was shining brightly, and even if the curtains were closed, the light would still come through!

"It doesn't matter, it's enough!"

Ying Feiyu just wanted to make the room a little darker so that the experiment would be more effective.

I don’t expect to make the room pitch black!

"What the hell is your kid doing?"

Looking at this series of operations, Ying Zheng was really confused.

"Experiment!"

Ying Feiyu ordered someone to light the oil lamp, and then personally picked up an egg and a goose egg.

Although the goose egg is relatively large, it is snow-white and he compared it to the moon, which is the moon!

And the eggs were compared to the earth, the land they stepped on!

Oil lamps were lit and compared to the sun!

"Father, take a good look at the egg in your hands, which is the ground we are stepping on now. It is indeed spinning...!"

"Impossible! Absolutely impossible! Why can't we feel it if it rotates?"

Ying Feiyu got ready and started to explain. After saying a few words, he was interrupted by his father, who almost couldn't hold back the anger in his heart.

Later, when I thought about it, the thinking of this era is quite stubborn, especially for people with the status of a scumbag. They are used to saying the same thing, and they must be self-centered, and they are easily unwilling to accept other people's suggestions!

"Father, let's do this, okay? You listen to me first. When I finish speaking, if you still don't understand anything or have questions, you can ask them again!"

Ying Feiyu was really patient and tried not to get angry.

Then he turned his attention to Feng Quji and others, "The same goes for you, don't say anything. If you have any questions, wait until I have finished speaking before you can ask them!"

"Uh huh huh!"

At this time, the old guys were sitting calmly on their chairs one by one, just like students, nodding their heads honestly.

"Okay, let's continue!"

"The land we step on is indeed circular, but its area is very large, with a circumference of about 80,000 miles!"

As Ying Feiyu spoke, he drew a circle on the surface of the egg with his finger.

"Hiss..."

Since they were not allowed to speak, even though Feng Quji and others were shocked, they did not dare to say anything and could only take a breath.

It turns out that the land they stepped on was so big!

Last year, the Qin Dynasty sent troops to attack the Maurya Dynasty. They were thousands of miles away, and they felt that it was far enough. This was a place that the Qin Dynasty had never reached before!

Unexpectedly, this is only a small part of the entire world!

"The land we step on can be called the earth, and the moon in the sky is also round, so it can be called the moon! Remember these two names!"

"First of all, the earth we live in rotates on its own. Each revolution is what we call twelve hours, which is twenty-four hours!"

Ying Feiyu suspended the egg in his hand in the air, parallel to the flame of the oil lamp, and turned it in a circle to simulate the rotation of the earth.

"Perhaps you may be wondering why the earth rotates but we don't notice it at all?"

As soon as the question came up, the veterans nodded repeatedly.

This is exactly what they have in mind!

"This involves another issue, called universal gravity!"

"All objects have an attraction. This is another aspect of knowledge. It is very complicated. Let's leave it until later!"

"To put it simply, the earth has an attraction, so we can stand here firmly. Even if we jump up, we will be sucked down again by this attraction!"

"Think about it, the earth is so big and doesn't rotate very fast, and we are firmly attracted by this attraction, so we definitely can't feel it!"

"oh!"

After a detailed explanation, the veterans suddenly showed expressions of enlightenment.

"Look! This candlelight is like the sun. When the earth faces the sun, the other side loses its light and becomes night! When the earth turns back, it becomes day! This

It’s called rotation!”

"At the same time, it will also circle around the sun. This is called revolution. This is how the four seasons of the year are formed...!"

Next, Ying Feiyu introduced the key to the formation of spring, summer, autumn and winter in detail.

"Let's talk about the moon again. It really revolves around the earth. While rotating, it revolves around the earth! Moreover, it itself does not emit light. The reason why we can see it emitting light at night is just

A refraction!”

This involves a lot of things, and Ying Feiyu explained it in detail.

The guide also explained why the moon waxes and wanes!

The old guys stared motionlessly at the two eggs in his hand, not even daring to blink for fear of missing something!

Then he used other eggs to represent metal, wood, water, fire, earth and other planets, and briefly explained why they would not collide!

"Okay, I have finished what I want to say. If you have any questions, please ask!"

After explaining all this, Ying Feiyu felt so tired that his mouth was dry and he drank two cups of tea in one breath.

The palace maid also pulled down the curtain blocking the window, and the sunlight poured into the room through the window again, making the person feel warm!

"call……"

The fire was blown out, and Ying Zheng and the old guys came out of their shock.

"Is everything your boy said true?"

Ying Zheng frowned, his face full of disbelief.

He had never heard such an incredible idea before, so he couldn't believe whether it was true or not!

"Father, I have spent a long time talking about my relationship and my mouth is dry. Do you think I am playing with you here?"

Ying Feiyu was not happy at that time.
Chapter completed!
