Chapter 22 I Want to Build the Great Qin Empire

You should know that the waxing and waning of the moon was very important to the ancients.

Because it allowed the ancients to judge time.

Otherwise, the ancients would not have used the phases of the moon as a unit of time.

A year consists of the moon waxing and waning twelve times.

Therefore, the ancients could not understand why the moon waxes and wanes, and they have been arguing about it for a long time, but there has never been a good explanation.

But now Zhao Yi actually said that the waxing and waning of the moon is due to the earth.

This was the first time Ying Zheng heard this.

He was very curious about what made Zhao Yi think that the waxing and waning of the moon was caused by the earth.

But for modern people like Zhao Yi, this is just common sense.

After all, humans have already flown out of the Earth and landed on the Moon, and photos of the Earth and the Moon are everywhere.

"I just said that the earth is a sphere, and we can simply call it the Earth."

As he spoke, Zhao Yi took out two big balls and a small ball.

"The moon is a small ball that revolves around the earth. It does not emit light, but only reflects the sun's light."

"So sometimes the moon is between the sun and the earth. In this case, when we look from the ground, we see the back of the moon."

As Zhao Yi spoke, he used large and small balls to demonstrate the orbiting movement of the Earth and the Moon.

"So we can't see the moon at the beginning of the month, but we can see the full moon on the 15th."

Everyone below was listening to Zhao Yi's speech attentively, and Ying Zheng and Wang Jian were no exception.

Because this kind of cosmic worldview was very novel to ancient people like Ying Zheng and Wang Jian.

"The moon revolves around the earth. The earth itself is also constantly rotating. One rotation is one day, and the sun rises in the east and sets in the west."

"While the Earth is rotating, it is also rotating around the Sun. One rotation around the Sun is one year."

"Because of the rotation of these three, the four seasons and tidal changes of the year are produced."

"Sometimes they also produce two strange celestial phenomena - solar and lunar eclipses."

As he spoke, Zhao Yi used the drawings on the blackboard to explain in detail the causes of solar and lunar eclipses.

Ying Zheng was shocked after hearing this.

Because in ancient times people always regarded solar and lunar eclipses as bad omens.

Associate it with various disasters.

It is believed that solar and lunar eclipses are warnings from heaven.

Every time a solar or lunar eclipse occurred, the king would offer sacrifices to the world, reflect on himself, and change his policies.

To ask God for forgiveness.

As a result, Zhao Yi told him that solar and lunar eclipses were just natural phenomena caused by blocking of light.

This had a huge impact on his worldview.

But he also felt that what Zhao Yi said was right.

A student asked a question below.

"Teacher, I still don't understand. If the earth is a ball, how come we don't fall out? Instead, we stand on the ground."

Zhao Yi replied: "It's very simple, because the earth has a force that sucks us to the ground. Its name is gravity."

"The force of gravity is the same for everything. So big objects and small objects fall at the same speed."

As he spoke, Zhao Yi demonstrated Galileo's gravity falling experiment to everyone using big and small balls.

Then everyone's worldview was impacted again.

Because they always thought that heavy objects fall to the ground faster and light objects fall to the ground slowly.

Now Zhao Yi has proved with facts that their ideas are wrong.

Zhao Yi smiled as he saw the people below doubting their lives.

He was well aware that what he was saying would be difficult for students to accept at first.

But he also wants to speak.

Because he wanted them to establish a correct scientific worldview. Only in this way can it be convenient for them to learn the mathematics, physics and chemistry courses and develop research in the future.

In this way, they can understand various drawings, build factories, and start factory production.

Instead of relying on Zhao Yi to personally supervise and teach everything like now.

That's why Zhao Yi asked all minors in the village to attend class.

They are the cornerstone of future modern industrialization.

Whether Zhao Yi can live a modern life with air conditioning and Coke in the future depends entirely on them.

Ying Zheng asked curiously, "If the earth is a sphere, then what percentage of the sphere does the Qin Empire occupy?"

"A very small part. This is a simple model of the earth I made..."

As he spoke, Zhao Yi took out a simple globe made of straw paper from under the podium. On it were six continents and seven oceans that he had drawn from memory.

Zhao Yi was very happy to hear his scumbag father ask this.

This shows that he paid attention to what I just said.

Ying Zheng stared at the area of ​​the Qin Dynasty drawn on the globe.

Originally, Ying Zheng believed that the Qin Empire he established should occupy most of the earth.

As a result, Daqin was only in a small area.

But Ying Zheng was not disappointed, instead he was very excited!
It turns out that there are so many places to conquer outside of the Qin Dynasty.

By then, the invincible army that Zhao Yi helped build can help him conquer lands outside the Qin Dynasty!
By then he can build an empire with extremely vast territory!

As Zhao Yi said, the sun will always rise above the territory of Qin.

If Zhao Yi knew what Ying Zheng was thinking.

You will feel that your scumbag dad is ambitious.

They all want to build an empire on which the sun never sets.

In fact, Zhao Yi had already planned this.

After all, if we want to develop modern industry, we need resources from all over the world.

In addition, Zhao Yi also thought about what the state system would be like after his scumbag father rebelled.

If the scumbag father abandoned his wife and children without any intention because he had no choice, then he could become emperor after the rebellion is successful.

If the scumbag father deliberately abandoned his wife and children, then Zhao Yi would find ways to sideline the scumbag father and establish a constitutional monarchy.

Zhao Yi continued his popular science teaching.

After the class, Ying Zheng learned that there are the North and South Poles in the world where it is always day and always night, and that there is land on the other side of the sea.

……

In the afternoon, Ying Zheng and Wang Jian sat in the carriage on their way back.

Ying Zheng said with emotion: "I didn't expect that listening to Zhao's lesson today would change my view of the world."

"Yes, I didn't expect the earth to be a ball. I just took a sword and a dagger to try Zhao's experiment. As a result, they really fell to the ground at the same time."

Ying Zheng was puzzled, "Ah~ Where does Zhao come from to know so much?"

"I think Zhao knows so much at such a young age. Maybe he has been taught by an immortal."

Ying Zheng agreed, "Indeed, only immortals know the truth about the world. They know that the earth is a ball."

"Now I know how small the Qin is. I want to plant the flag of the Qin everywhere on earth."

"I am willing to fight for your majesty, plant the flag of the Great Qin all over the world, and make the whole earth the territory of the Great Qin."

"Okay. Don't die before you conquer the entire earth for me."

"My minister obeys."

……

On the other side, Zhao Yi walked into the factory in the village.

He was going to direct the village craftsmen to build a steam engine.

After two days and nights of overtime work, the village blacksmith finally forged all the parts of the steam engine...
