Under the gaze of thousands of pairs of eyes, the constantly swinging iron ball slowly knocked down the wooden bar representing the fifteenth scale.

The traces on the sand table that were pulled out by the pendulum are like slender petals, revealing an extreme sense of beauty!

This is the engraved line that represents the truth of magic!

Only then did Lynn point to the sand table, look at Yoland, and said teasingly.

"I guess it's pretty clear, isn't it? Mr. Yoland? ”

"That's the evidence you're looking for! The rotation of the planet is not without influence, but this force must be amplified by the pendulum to be intuitively displayed in front of you and me. ”

Yolande sat on the ground with a pale face, looking at the iron ball that was still swinging without saying a word.

Beside him, a wizard from the Prophetic School shouted hysterically. "This can't be, this can't be! You must have cast a spell on the pendulum! ”

As soon as these words came out, several great wizards on the field couldn't help frowning, their faces were a little unhappy, were there any magic fluctuations, could they still not feel it?

Lynn looked at the wizards of the Prophecy School who were still unwilling to accept the facts, shook his head, and said in a loud voice.

"The materials I use aren't hard to get, are they? Anyone under the same conditions can perfectly reproduce this experiment......"

"The truth is there, not transferred by anyone's will, the reason why there is a change of day and night in this world is due to the rotation of the planet, and the change of the seasons is related to the movement of the position of the direct point of the sun......"

Lynn stretched out his hand and simulated the orbital motion of celestial bodies with several water masses, and gave everyone a unique astronomy lesson in the most concise words.

The wizards present listened in fascination, and no theory had ever been able to explain the changes of day and night, the seasons, and the movement of the stars so clearly.

The veil of mystery in the world seems to have suddenly been unveiled into a corner, and although it is only the tip of the iceberg, it is enough to make people feel trembling.

Until Lynn's words fell, the hall of the seminar was still full of falling pins, and everyone was immersed in thinking about the laws of the planet.

The silence lasted for several minutes, and as more and more people came to their senses, the hall of the seminar suddenly burst into thunderous applause, some people even took off their hats and bowed to Lynn, and some people shouted loudly to vent their excitement.

"What a wonderful and irrefutable theory!" Ogst was also clapping, and said in an appreciative tone.

Lynn's delicate and regular picture of the stars made Raphael's brain tremble, and countless inspirations poured into his heart, and if it weren't for the fact that the seminar was not over, he would have been impatient to go back and turn his inspiration into sculpture.

"I knew you could do it, Professor Lynn......" Philip excitedly stepped forward and hugged Lynn, he had already seen the Silver Moon Medallion waving to them.

Lydia, Elok and the others looked at Lynn with admiration and longing, and Peirce fantasized about when he would be able to explain the magical theories he had researched under the eyes of Professor Lynn, and won the applause of the audience.

But their excitement was soon shattered, as Lynn was quick to speak.

"Lydia, Jonny, Elok, and Peirce, why don't you keep a record of the pattern of the pendulum's motion, and the time that passes through each tick? The length of the wire rope and the weight and circumference of the pendulum should also be clear, draw its motion curve, and calculate the data, this is your homework today! ”

"Huh?" Peirce, who was originally immersed in fantasy, was immediately pulled back to reality, and his face suddenly drooped, why is there such a thing as homework when it comes to Greenriel?

"Have you all written it down?" Elok hurriedly looked at the two witches on the side.

Lydia shook her head, her head a little dizzy as she stared at the swinging trajectory of the pendulum.

"I've recorded that the length of the wire rope is 60 meters, the weight of the pendulum is 30 kilograms, the time for each deflection scale is 5 minutes and 3 seconds, and the swing cycle is ......" Jonny burst out of his recorded data.

Alok and the others looked at Jonny and were so moved that they were about to cry.

You are simply our savior!

Compared with Lynn, who became the absolute focus of the meeting, the wizards of the Prophecy School were all dead-faced, and they spent more than a hundred years and countless energy observing the movement of the stars before they painted a perfect star map.

As a result, they are now told that the star map is actually wrong, that their efforts have been in vain, and that there is not a continent under their feet, but a rotating ball......

Under such a huge blow, the wizards of the Prophecy School were all on the verge of collapse, and for a moment it seemed as if the whole world was about to collapse!

"Cheer up, we haven't lost yet, this pendulum experiment just proves that there is a strange force affecting the movement of the iron ball." A prophetic witch stepped forward and spoke firmly.

"But apart from the geostrophic deflection force, what else can affect the trajectory of the pendulum?" Yolande was already in despair, after all, such a large pendulum was placed there, and Lynn really didn't exert any magic on it.

"Have you all forgotten? Master Harrov is working on a theory of gravity, using the data we give us on the stars, and if there is any force that can affect it, then I guess it must be gravity! The witch said in a loud voice.

Hearing this, the wizards of the Prophetic School such as Yolande were immediately shocked and immediately regained some confidence.

Yes, if their research is wrong, then how can the legendary wizard Lord Harrov uncover the mystery of gravity from the data of these stars.

Could it be that even the great legendary wizards could not see these mistakes?

Yolande knew that Lord Harrov's research had reached the most critical moment, and it was a great doctrine that was enough to change the entire magic theory of the Wizarding Lands!

After all, this involves the mystery of space and time magic!

Just as Yolande and the others were thinking, the door of the magic seminar was suddenly opened.

No, it is not quite appropriate to describe it as open, and the door has been locked long ago in order to ensure that the progress of the seminar is not disturbed.

And now the doors on both sides have been smashed to the ground with a loud bang......
