"Professor, should he be able to hold on?" Alok muttered to himself. Those wizards from the school of prophecy seemed to be numerous and powerful, as if they were going to overpower others with their force. Philip was also a little worried. He had wanted to go out with them, but was held back by Lin En.

When Yolande saw Lin En walk onto the stage, he asked impatiently.

"Mr. Lin, I have read your theory. According to your theory, all the stars, including the continent under our feet, revolve around the sun, right?"

"To be precise, the planets in this galaxy revolve around the sun." Lynn corrected the mistakes in Yolande's words.

Yolande ignored this difference and said regretfully, "But I found that you seem to have overlooked a very important issue!"

"What's the problem?" Lynn asked curiously.

"Since you mentioned in the Magic Daily that the period of this continent under our feet orbiting the sun is 360 days, which is exactly one year, how should the phenomenon of day and night alternation be explained? Could it be that only one day and night passes in a year?" Yolande questioned.

According to the theory of the prophecy school, it is precisely because the sun revolves around the continent with a period of one day that there are rising and setting of the moon, and day and night.

Lin En was speechless. He thought Yolande was going to say something very high-end, so he immediately explained with a smile on his face.

"It's very simple. That's because the planet under our feet is not only rotating around the star, but also rotating on itself all the time. This is why we see the alternation of day and night."

Lin En stretched out his hand and created two water balls of different sizes in the void, letting the smaller one revolve around the larger one while rotating on itself. Each rotation represented the alternation of day and night.

"Rotation?" Yolande was stunned for a moment. He didn't expect Lin En to come up with such an explanation, but he soon laughed.

"I have to say, your theory is very interesting. But if, as you said, the continent under our feet is rotating non-stop, or even moving around the sun, then why aren't we thrown out directly?"

Yolande raised his voice a little, and the sound continued to echo in the auditorium.

All the wizards present were discussing the issue, and even the wizards who originally supported the planet theory began to waver under such sharp questioning.

After all, Yolande's words are easy to imagine. For example, if you put a grain of rice on a ball and then rotate the ball rapidly, the grain of rice will inevitably be thrown out.

What's more, the continent beneath their feet is so huge that once it moves, it will inevitably produce extremely terrifying power. Even if they are lucky enough not to be thrown out, they should definitely be able to sense it!

Philip was as anxious as an ant on a hot pan, as if he was the one being targeted on the stage.

Lin En's expression remained unchanged, and he asked with a smile, "You should have worked in a carriage, right, Mr. Yolande?"

"Why are you asking this?" Yolande said hesitantly.

"That's because we are in the carriage during the ride, and due to friction, we move with the carriage. Of course, because the speed of the carriage is sometimes fast and sometimes slow, it is not intuitive enough..." Lin En said, suddenly turning his head to look at several great wizards. "I think Master Raphael and Master August, who have ridden in an airship, should have a better understanding of this!"

Everyone's eyes immediately turned to Raphael and August. After a moment of contemplation, the two nodded in unison.

Unlike a carriage, the airship was completely floating in the air. With the help of a windproof magic array, it traveled very smoothly. They could hardly feel that they were moving so fast on it.

"The same is true for this planet! Previous free fall experiments have proved that the resistance we feel is based on the existence of elements. Under the influence of gravity, all elements and matter change their positions along with the rotation of the planet, so of course we can't feel that we are moving. If one day it suddenly stops rotating, we will probably all fly out..." Lynn said jokingly.

"Nonsense!" A red-haired witch beside Yolande shouted loudly, interrupting Lin En's words. "Lord Harrof once flew to the top of the world. If the continent under our feet is really rotating, then Lord Harrof should have flown to other places with the rotation of the continent in such a long time..."

"The influence of gravity is very large, ma'am, much larger than you can imagine. It is so large that even if we rise to an altitude of hundreds of thousands of meters, we cannot escape its control!" Lin En said lightly, then looked at everyone and spoke loudly.

"Just as we cannot perceive that the planet under our feet is round, the planet's rotation speed is very slow compared to its huge size, and we are as small as dust, just like an ant building a hole in a hill. To it, this hill is the whole world."

The discussions in the hall became more and more intense. Some people agreed with Lin En's theory of planetary rotation. After all, it could well explain the problem of day and night alternation.

However, more people still have deep doubts. According to Lin En, because they are rotating with the planet, they cannot perceive that they are also rotating?

This is ridiculous! It's not magic at all! "Where's the evidence? What evidence do you have to prove that the continent under our feet is rotating? This is all just your fantasy!" Yuland sneered sharply. "According to your theory, aren't we also running along with this continent when we sleep at night..."

“Then did you move by yourself when you were riding in the carriage?” Lynn asked with amusement.

"Of course..." Yolande paused. He wanted to say that he didn't move, but when he thought about it carefully, he realized that he was indeed moving.

This contradictory feeling made Yolande, who didn't know what a reference frame was, confused. In the end, he could only conclude that he did not move, but the carriage moved him.

But this conclusion undoubtedly proved Lynn's rotation theory. Yolande was troubled for a long time and did not speak.

"As for the evidence of the planet's rotation, of course I have it!" Lin En ignored Yolande who was in a dilemma, but looked at the seat of the Iyeta School and spoke.

"Johnny, Alok, Pierce, bring up everything you prepared!"
