Harrov pondered for a long time before he reluctantly accepted the fact that a perfect circle did not exist, and then continued to ask. "I understand the first point you said, but what is the second point?"

"The second point is the interference of the gravitational attraction of other planets, even if the planet under our feet, the initial orbit tends to be close to a perfect circle, under the interference of the gravitational attraction of other stars, after tens of millions of evolutions, there will inevitably be a certain deviation." Lynn explained.

"I see!" It suddenly dawned on Harrov that gravity exists between everything and everything, and it will inevitably interfere with each other, and even if the magnitude of this interference is small, it will be magnified enough to affect the orbit of the stars under the action of time on the scale of tens of millions of years.

There's a third effect, which Lynn doesn't say, and that's that the star itself isn't stationary, it's moving around the center of the galaxy, so interference is inevitable.

However, this is beyond the understanding of these wizards, who have not even figured out the rotation of the planets, and they are ignorant of the larger picture of the universe.

"I have another question, which is that the star of the first law is at a certain focal point of the ellipse, what is this focus?" Harrov continued to ask.

"I'm afraid it's not convenient to explain directly, why don't you just draw an ellipse?" Lynn said with a smile.

Without hesitation, Haroff stretched out his hand, using his right index finger as a pen, and with magic as ink, he drew an ellipse in the void, and then looked at Lynn, waiting for his answer.

, draw an ellipse freehand, it's still so standard.

The corners of Lynn's mouth twitched, he finally understood why the "technology tree" in the wizarding land was so messy, because many instrument wizards didn't use it at all, and when they encountered problems, they probably only thought about which kind of magic was more convenient to solve.

Seeing this, Lynn, who couldn't laugh or cry, could only turn his head to look at the apprentices.

"Ellock, you'd better draw it!"

Elok nodded excitedly, he still knows how to draw an ellipe, not to mention that this is an opportunity to show his face in front of the legendary wizard, Elok trotted all the way and quickly found two small sticks and a string, and then put the rope on the two sticks that were inserted into the ground, as a fulcrum, and drew a circle around the two small sticks with a quill on the string.

An ellipse immediately appeared in front of Harov.

"The position of these two sticks is the focus of this ellipse, and their special feature is that the sum of the distances from any point drawn on the arc to the two focal points is the same, and some scholars in the [Secret Law Society] even believe that the perfect circle is actually an ellipse where two focal points happen to be in the same position......"

With the help of this process of drawing circles, Lynn explained to Haroff the interpretation of the ellipse and the derivation process of Kepler's three laws.

Harrov was fascinated by what he heard, and in the end he couldn't stop clapping. "Wonderful, so wonderful! I didn't expect that through the Olympiad, I would be able to reproduce the picture of the movement of the stars so intuitively and clearly......"

"If you had stayed a little longer last night, I wouldn't have to spend most of the day correcting these three laws in the most primitive way." Harrov said with emotion that the conclusions he had come up with all night's work were now perfectly summarized by Lynn in a few short sentences and a few Olympiad formulas.

"Lord Harrov, Professor Lynn wanted to visit you in person last night, but unfortunately he was stopped at the door." Philip on the side hurriedly spoke.

"And this kind of thing?" Harrov was stunned for a moment, then turned to look at Lynn.

"Ms. Theresa believes that your research has reached a critical juncture, and she is afraid that she will not be able to spare time for this meeting." Lynn shook her head and spoke. "I told her that these laws and formulas should help you in your research, but this lady seems to have a little preconception about me."

Harrov's face immediately became ugly, when he was in the manor before, Theresa didn't explain to him like this!

After Lynn pointed out the other party's problem, she didn't add fuel and vinegar to continue to accuse Theresa of offense, a witch who couldn't see the situation clearly was not worth his deliberate words, one or two sentences were enough.

"Before coming to the land of wizards, an adult of the [Arcane Society] entrusted me to give this ring to a very wise and learned person to discuss the mysteries of the universe, time and space, and the next meeting should be around twelve o'clock tonight." As she spoke, Lynn pulled out a beautifully styled ring.

It was the [Ring of the Faceless] that he had reforged, but compared to before, the shape of the ring had changed a lot, the most obvious was the blooming flower of thorns on the ring face, which had become a very strange geometric pattern.

The outer ring is a circular clock, and the inside is a pyramid-like motif, with a striking geometric eye in the center of the pyramid.

That's the all-knowing eye!

Although he had a bad quarrel with the other party's apprentice Theresa in front of the manor, Harrov was able to put down his head and ask him, the three-ring wizard, all kinds of questions, and after thinking about it, Lynn handed out the only signal transmitter he had made.

Harrov solemnly reached out and took it, and after carefully examining the alchemy patterns on the ring, he quickly judged that the function of this thing was to project its own magic power somewhere.

This method is not very new, but the first contact with the [Secret Law Society], Harrov is still very concerned.

In his opinion, Lynn was like a representative sent by the [Arcane Society] to engage with the Wizarding Lands, and this gathering should be a formal contact between the two high-level leaders to discuss cooperation, or exchange some more esoteric magical issues.

After getting the ring, Harrov didn't stay long, and soon left, he had to go back and think about what knowledge he could use as a bargaining chip.

It wasn't until after Haroff had left that Lynn asked in his head.

'071, are you sure the magic realm is safe enough? There's no chance of being taken again, right? ’

Lynn hadn't forgotten that this thing was taken from Helram's hands, and normally he wasn't worried, after all, the brain's computing power was very strong, but in the face of a legendary wizard, he wasn't so sure.

[The original form of magic transmission and reception was too simple, and has now been replaced by quantum encryption, and there is no possibility of being cracked in theory.] 】

Lynn nodded reassuringly.
