Water Margin: My 108 Heroes Come from All Heavens

did not expect.

He was actually Zhao Ling'er's official school professor, responsible for teaching her her lessons on a regular basis.

"Grand Tutor Liang, you just said... you can prove the earth is round?"

Zhao Ling'er pressed for more information.

"certainly."

I don't believe it.

Zhao Ling'er shook her head, looking unconvinced: "Professor Shi has studied this for so many years and hasn't been able to prove it, which means this theory is wrong."

"What if I can prove it?"

Liang Shan countered with a question.

"From now on, I'll do whatever you say!"

Zhao Ling'er crossed her arms, looking on with an expression of anticipation.

"It's a deal!"

Liang Shan smiled slightly.

He has countless methods to prove that the Earth is round.

I learned in junior high school geography class in my previous life that the most intuitive way to prove that the earth is round is to look at ships sailing in the distance.

First, you see the mast.

Looking at the ship's hull, this is the best evidence of the Earth's curvature.

"That doesn't seem right?"

Zhao Ling'er interrupted Liang Shan and corrected him very seriously: "I remember when I went to see Grandma on Immortal Spirit Island before, I could see the ship directly."

"You can see the ship's hull directly?!"

Liang Shan was taken aback.

He subconsciously glanced at Shi Jieren beside him.

"That's true."

Shi Jieren nodded and said, "When sailing out to sea, the hull and the mast of the ship appear at the same time."

"Grand Tutor Liang, you don't even have this much common sense, do you?"

Zhao Ling'er began to have doubts.

Liang Shan's lips twitched a few times.

common sense?!

You call this common sense?!

"Then let's try a different approach."

Liang Shan raised his head, pointed to the clouds floating in the sky, and asked, "Has the princess ever wondered why the shadows on the moon are arc-shaped during a lunar eclipse?"

"An arc shape? During a lunar eclipse, the shadow on the moon is a straight line."

Zhao Ling'er blinked and turned to look at Shi Jieren: "Didn't you just teach me this?"

"The princess is intelligent."

Shi Jieren nodded, looking very pleased: "The shadow of a lunar eclipse is actually the shadow of the earth. The edge of the shadow is a straight line, as if it has been cleaved in two."

"???"

Liang Shan was dumbfounded once again.

A lunar eclipse without an arc? Was it split in two by someone?!

He gritted his teeth.

I don't believe in superstitions.

They switched to a third approach: "Let's do a simple experiment, Princess, please watch—"

He squatted down.

Pick up an ant from the garden and place it on a leaf.

"Imagine this ant represents you and me, and this leaf represents the earth."

"Ants crawling on a leaf can never tell if the leaf is flat or curved because they are too small, but if we roll up the leaf..."

He rolled the leaves into a tube shape.

Ants crawled on the wall of the tube.

"Ants may think they are walking in a straight line, but they have actually turned."

"so what?"

Zhao Ling'er blinked, looking completely bewildered.

"Therefore, the earth is also curved, but we humans are too small to feel this curvature."

Liang Shan explained in a very serious manner.

Zhao Ling'er tilted her head, thought for a while, and suddenly pointed to an eagle flying overhead: "That eagle is flying so high, it must be able to see it, right?"

"Even the eagle couldn't tell."

Liang Shan shook his head.

"What about the immortals? They're flying in the sky, can't you even see them?"

Liang Shan was speechless.

He almost forgot.

This world contains demons, gods, and even beings like the Old Mother of Lishan and Bodhisattvas.

"I heard my father say that someone spent three days and three nights flying 100,000 li in the air, and when he came back he said that the earth was boundless and could not be seen to the end."

Zhao Ling'er frowned and pondered seriously, "If the earth is really round, it should return to its original position after one rotation."

Liang Shan opened his mouth.

I feel like my worldview is being utterly crushed by this absurd world.

Ten thousand miles.

They flew for three days and three nights?

Is this even human? Don't your legs get sore?

"and."

Zhao Ling'er continued, "I also heard my father say that the Song Dynasty's territory is 128,000 li wide from east to west and 96,000 li long from north to south. If the earth were round, how curved would such a vast territory be?"

"Our human race has countless wise ancestors; it's impossible that no one discovered that the earth is round."

Liang Shan stood there, stunned.

128,000 li?

In his memory, the Earth's equator circumference was only 80,000 miles.

This is the Great Song Dynasty.

Is this still the Song Dynasty he knows? Its territory extends beyond the Earth's equator.

"This is only the territory of the Great Song Dynasty."

Shi Jieren nodded and echoed, "According to ancient records, the Song Dynasty was only a small part of this continent. Further west were the Western Regions, India, and the Abbasid Caliphate... No one has yet been able to accurately measure the size of this continent."

Has anyone tried it?

Liang Shan swallowed hard and couldn't help but ask.

"have."

Shi Jieren sighed, his face full of regret: "Two hundred years ago, the great master Xuanzang exhausted his family fortune and, with three disciples, traveled westward, enduring countless hardships..."

"etc!"

Liang Shan's eyes widened, and he interrupted, "Who are you saying is heading west?"

"The great master Xuanzang."

Shi Jieren paused for a moment before replying, "He was a renowned Buddhist monk who made a grand vow that he would not become a Buddha until he found the boundary of heaven and earth, but even he... could not find the end of the world."

Liang Shan fell completely silent.

Good guy.

This world even has Tang Sanzang.

only……

To his utter surprise, Tang Sanzang's journey to the West wasn't to obtain Buddhist scriptures, but rather to find the end of the world!

What a great geographer!

"Grand Tutor, can you prove it?"

Seeing that Liang Shan remained silent, Zhao Ling'er put her hands on her hips and snorted.

Liang Shan took a deep breath.

He clasped his hands in a respectful bow and said, "Your Majesty, I am but a humble subject, and I apologize for my lack of knowledge and learning."

At the same time, he began to wonder what the underlying logic of the world he had transmigrated to was.

All common sense about Earth is invalid here.

What are the laws governing the movement of the sun, moon, and stars?

do not know.

What causes tides?

do not know either.

All the scientific knowledge I accumulated in my previous life will probably be rendered useless in this world overrun by demons.

No wonder...

Despite years of research and racking his brains, the leader of the Moon Worship Cult has been unable to prove that the Earth is round.

What the hell does this prove?

"I told you the earth was flat!"

Zhao Ling'er stood with her hands on her hips, looking smugly at Shi Jieren.

"Grand Tutor Liang, you are not..."

Shi Jieren immediately became anxious: "Didn't you believe me?"

"Believe is one thing."

Liang Shan patted him on the shoulder and sighed, "But this world is too unpredictable, and I can't prove it either."

Let's just say that.

Even if Magellan were resurrected, all we could say was: Xiahou Dun met Louis XVI.

"Thump! Thump! Thump!"

Just then, the school bell rang in the princess's residence.

"Grand Tutor Liang, it's time for class."

Shi Jieren realized what was happening and reminded him.

Zhao Ling'er glared at him.

Although reluctant, he obediently sat back on the stone bench and casually opened a book.

He looked at Liang Shan impatiently: "Grand Tutor Liang, is it the Analects or Mencius today? I know them by heart."

"I won't learn those things."

Liang Shan waved his hand.

"Then what should we learn?"

Zhao Ling'er raised an eyebrow.

"fall in love."

Liang Shan remained expressionless.
