"To the west?" Xu Yichan was stunned for a moment, and then couldn't help sneering: "How can the land of the east go west?" It's the exact opposite! ”

Ye Qiange smiled, not surprised by Xu Yichan's answer.

At this time, everyone's perception of the world is still on the theory of the heavens.

Although the Hun Tian Theory is a little more advanced than the Gai Tian Theory, it has not changed much in essence.

It is still centered on the round sky and the earth.

It is believed that the earth is flat, the sky is round, and the sky is like a big bowl that covers the earth firmly.

This is common sense, and it has long been ingrained in people's minds.

According to this statement, if you are located in the east, you will only go further and farther away, and indeed you will never be able to reach it.

Ye Qiange picked up the brush from the table, spread out another piece of paper, drew a circle on it, and said with a smile: "If the world we are in is a big ball, go east to the Western Regions, and go west back to the East, what is the difficulty?" ”

As he spoke, he drew a circle on the circle with his brush.

"Balls?" Xu Yichan's small mouth opened, revealing two crystal clear teeth, and her eyes were full of surprise.

But after a while, her face was full of doubts, and she couldn't help humming: "Since ancient times, there are clouds, and the sky is round, how can you be allowed to make things up?" ”

Ye Qiange raised his eyebrows, and said confidently: "I know that you won't believe it easily, in fact, to prove it, it's very simple." ”

Xu Yichan pursed her mouth and looked at Ye Qiange coldly.

"I wonder if Your Majesty has ever been to the beach?"

Xu Yichan nodded slightly, "Naturally, I've been there." ”

"Then let me ask Your Majesty a question, why does the hull disappear first, and the mast disappears later? If the sea is flat, the ship will gradually become smaller, and there will be no such change. ”

Xu Yichan's expression froze, but she was suddenly asked.

"Actually, if you look closely, you can easily see that the sea is arc-shaped, not flat as you think."

After pondering for a long time, Xu Yichan couldn't help believing it, but she was still shocked in her heart.

"But if it's a ball, why didn't we fall it?"

Xueba deserves to be a scholar, and instantly thought of the crux of the problem.

This is due to a gravitational force that has a strong attraction that pulls objects on the ground towards itself and prevents them from leaving. For example, when water flows downward, ripe fruit falls instead of flying into the sky, and there are countless examples. ”

Xu Yichan only felt that her worldview had collapsed.

The example given by Ye Qiange is very simple and easy to understand, and it is very common, but from small to big, thinking about it carefully, it is impossible to refute it.

"That's all that the seafarer said?"

Ye Qiange nodded and said, "He said that he started from the Western Regions, went all the way to the west, passed through the mainland, crossed the ocean, and came to Daxu in a circle. ”

To the west of Daxu is the Western Regions.

After a circle, it was back to square one.

Xu Yichan gasped, her intuition swayed, she never expected that the world she was in was actually a huge ball!

After listening to it, I had to believe it.

"What else did that man say to you?"

Ye Qiange saw Xu Yichan's stunned appearance, and she understood very much.

After all, what he said was really too shocking, and it was normal for Xu Yichan to be difficult to accept for a while.

Seeing Ye Qiange shaking his head, a trace of disappointment flashed in Xu Yichan's eyes.

"Although he didn't say anything, but-" Ye Qiange couldn't help but smile when he saw it, "When he left, he gave me a map." ”

"What map?"

"World Map."

"You can take it with you." Xu Yichan's eyes flashed, and there was a little urgency on her face.

"I didn't bring it, but I can draw it now." As a science student who is better at liberal arts than science, drawing a map of the world is a piece of cake.

As he spoke, he took out a charcoal pen from his bosom and began to draw, the tip of the pen rustling when it touched the paper.

Xu Yichan looked at the charcoal in Ye Qian's singer, and a curiosity crossed between her eyebrows, but she quickly withdrew her gaze and moved her gaze to the paper.

Ye Qiange drew very quickly, and with half a cup of tea, a very fine world map appeared.

"This is the map of the world?" Xu Yichan stared at the map intently, her eyes overflowing with surprise.

Ye Qiange pointed to the east of the Asian continent with a pen, "This is Da Xu." ”

"Why is it so big?" Xu Yichan is very dissatisfied, Xu Yang is a big country, but in this map, it seems so small.

"It's not small." Ye Qiange muttered, this is much more than the Celestial Empire in later generations.

"No, it's still too small."

Xu Yichan's eyes looked faintly, a flame ignited in her eyes, and she looked around Da Xu, and her eyes couldn't help but roll.

Ye Qiange was a little speechless, and secretly slandered, when he was an emperor, sure enough, every one of them wanted to open up territory and expand the field.

Obviously, Xu Yichan is no exception.

"Hey."

After looking at it for a long time, Xu Yichan suddenly sighed, gritted her teeth, and retracted her gaze unwillingly.

According to Daxu's current national strength, to start a war and open up territory is tantamount to seeking a dead end.

The Empress's ambitions were extinguished before they could swell.

Ye Qiange was a little unbearable, and said: "You don't have to just stare at the surroundings of Daxu, these places are poor in materials, arable land is scarce, and they are not suitable for people to live in, even if they are defeated, what is the use." ”

"At least it looks bigger." Xu Yichan muttered.

Ye Qiange rolled her eyes, and the Empress began to drill the horns again.

He pointed to the Australian continent, "This continent is not much smaller than Da Xu, but it is only inhabited by tens of thousands, perhaps hundreds of thousands of people, these people are not civilized, and they are still living a life of drinking blood." ”

"In such a big place, there are only 100,000 people?" Xu Yichan's eyes widened.

Ye Qiange nodded, "Surrounded by the sea here, the climate is suitable, the cultivated land that can be cultivated is not much less than that of Daxu, and more importantly, there are countless minerals here." ”

Xu Yichan's breath tightened, and the flames in her eyes gushed out.

With only a hundred thousand people, I only need to send an army of 10,000 people to sweep the invincible!

"It's called the African continent, it's home to countless species of animals, it's the largest desert in the world, and the people who live on it are a dark-skinned human race."

"Kunlun Nu, I've seen it." Xu Yichan said softly.

The Kunlun slaves in her mouth refer to darker-skinned servants, most of whom are indigenous to Southeast Asia, and some are Africans, probably with the Arabs.

Ye Qiange was relieved, Chang'an is an international metropolis, and people of all colors walk the streets, but it is not strange.

"This North and South Pole is frozen all year round, covered by ice and snow, the temperature is extremely low, and in a year, there are half a day and a half a night, and people cannot reach it."

"It's wonderful." Xu Yichan was like listening to the Arabian Nights, shocked with yearning and fascination.

Ye Qiange then looked at the last two continents, and couldn't help but say with a serious expression: "What I said just now, several high-yield grain crops all come from here. ”
