Theodore's violent words immediately attracted everyone's attention.

Facing the surprised eyes of the crowd, Theodore didn't say much and directly handed over the so-called research manuscript. Kevin and others took it and looked at it one by one, with sarcastic expressions on their faces.

When the manuscript was handed to Hellram, the great wizard did not laugh, because he found that the manuscript mentioned something called air resistance...

Lin En just took a sip of tea and did not rush to explain. Instead, he waited for the professors to finish reading all his "research materials".

Although he didn't know much about the level of "magic" in the wizarding land, Kelu had left him two basic books, "Element Analysis" and "Basic Magic General". These manuscripts he wrote were all extensions of the existing theories in the wizarding land, and they were very easy to verify.

In just five or six minutes, the wizards finished reading the dozen pages of the manuscript. As the so-called law of free fall was too unreliable, they only glanced through the rest of the content. Then they were surprised to find that there was an argument in the manuscript that was even more outrageous than this.

"Listen, your name is Lin En, right? I don't know what Kelu was thinking when he asked you to give this ridiculous manuscript to the Land of Wizards, but if I may be frank, the magic theory of the [Secret Law Society] is full of loopholes..."

Kevin threw the paper in his hand casually on the table and said speechlessly, "And you actually think that the continent under your feet is a sphere? This is ridiculous!"

"Why can't this world be spherical? I think no one has verified it yet." Lin En slowly put down the teacup in his hand.

Although due to his ability constraints, he is unable to fly into space to confirm this thoroughly, but the fact that he can stand here already explains a lot of things.

For example, the mass and gravity of the planet under his feet must be very close to those of the Earth, because the gravity he feels is almost the same.

The changes of the seasons and the sun and moon can also serve as evidence of the rotation of the planet and the revolution around the star. After leaving the foggy sea, the first thing he saw when he looked towards the port was the top of the [Screaming Tower], and then the tower body! The most important thing is the star map. As long as the star is placed in the center, a perfect galaxy operation map can be constructed. This is the most direct evidence!

If the star map hadn't indicated that this star had only five planets orbiting it, Lin En would have begun to wonder if this was the Earth from another parallel world.

Because they look so similar! "Since the Yieta Harbor faces the sea, I wonder if you have used long-sighted magic or alchemical eyepieces to look out at the sea. If so, I think you should have noticed that when a sailboat approaches from a distance, you must see the sail first, and then the hull!"

As he spoke, Lin En opened his hands, and under the surge of magic power, a huge and turbid water ball appeared in front of everyone, and then he inserted a feather straight into the water.

Then the water began to flow, and the feather pen rotated straight from the bottom to the top. The first thing I saw was the tip of the feather...

The wizards present immediately understood what Lin En meant. The entire huge water ball was like the continent under their feet, and the feather pen was the ship. If the continent was flat, then they would be able to see the entire hull from far to near.

The sails will only be seen first if the surface is curved.

"It seems to be true..." Theodore frowned. Every Sunday he would go to the port to greet new visitors. Sometimes he needed to use farsightedness magic. It was just as Lin En said. He would always see the sails appear on the sea level first.

This theory seemed to make some sense, but Theodore always felt that something was wrong.

As he spoke, the college professor also followed Lin En's example and directly made a ball of soil to simulate the continent, and then attached a layer of water to the surface.

Then he released the [Hand of the Mage], and the water immediately flowed downwards, leaving the soil ball and forming a puddle on the table.

"Look, it's like this... this is not going to work!"

The college professor said complacently, and Theodore and others nodded.

"If the continent is a semi-arc, won't the water fall downwards?" Lin En asked speechlessly.

The professors were immediately stunned. The farsightedness of the ship at sea indicated that the seawater was most likely attached to the curved land, so the water would definitely flow downwards and would never stay in the same place. This was totally contrary to common sense! Before they could figure it out, Lin En continued to speak. "Also, how can we determine which side is down?"

"Need I say more? Of course the sky is up and the land is down. This is guided by gravity!" Theodore said with a frown. He didn't understand why the other party asked such a stupid question.

"Really? How about this?" Lin En raised his eyebrows, removed the water ball, placed his hand on the earth ball made by the academy professor, and activated the [Mage's Hand]. The originally soft earth ball slowly compressed inward and finally turned into a solid sphere.

"If the force given by the [Mage's Hand] is regarded as gravity, then for the exact center of the earth ball, which side is up and which side is down?"

Theodore was completely stunned. Lin En's metaphor of the continent as a ball of earth was very simple and easy to understand. Naturally, he saw it very clearly. But it was precisely because he could understand it that he could not hide the shock in his heart.

For the center of the sphere, there is gravity on all four sides, so the front, back, left and right are all up, and the bottom is at the center of the sphere, so the water flow will inevitably attach to the sphere.

The professors present also noticed this and started a heated discussion. Kevin was completely unwilling to believe this so-called planetary theory and insisted that the continent was flat and that the farsightedness of the sailboat was just a coincidence and could not be used as direct evidence.

Philip and others hold the opposite opinion. They believe that what Lynn said may not be unreasonable. At least it is a plausible theory that can be used for reference research to confirm its authenticity.

When everyone was arguing with each other and almost quarreling, Theodore looked at Lin En and asked again. "You mean there is a force that compresses everything towards the center of this continent? So the water can stay on the surface of the continent?"

Before Lin En could answer, Hellram, who had been flipping through the manuscript, finally spoke.

"The truth should be the opposite. There is some kind of force in the center of the continent that spreads out in all directions, forming a gravitational field... dragging everything inward. This is what you want to express, right?"
