Greetings, Mister Principal

While the students of Luna Nova Magical Academy were suffering from math test papers, a new storm was quietly set off in the Rainbow Tower.

"The latest issue of Astrologer Monthly supplement, the latest issue of Astrologer Monthly supplement is on sale. Would you like to see the major breakthrough of His Excellency Regens? Come and buy an Astrologer Monthly" supplement!"

Rainbow Tower ushered in the first shower in the summer.

As if to indicate the coming turmoil, the dull thunder was echoing in the sky. The raindrops hit the windows, making a continuous and monotonous noise. The whole city was shrouded in the rain, the people on the streets were moving in a hurry, their leather shoes stepped on the shallow puddles, splashing rain water on the ground.

Angeliis was holding an umbrella. Today was the weekend. He didn't have to deal with the paper review work. At this time, he was about to attend regular gatherings of his old friends. He walked across the street and heard the clerk of the bookstore selling periodicals. He thought about it and stepped into the bookstore.

The bookstore called Star of Campanella was not big. The bookshelves on three walls that reached the ceiling were filled with all kinds of magic books. In the center of the store was a low counter filled with various academic journals.

As a mage who focused on alchemy, Angeli usually only subscribes to several alchemy-related periodicals, including "Alchemy". Therefore, if he wanted to read the periodicals of other studies, he could only buy them separately or rent them from the library.

There was also a special situation, that was, when the supplement was issued, it was generally not sold through regular subscription channels, but sold at the store.

Generally speaking, the appearance of supplements mostly meant that some important results had been published recently, and the inclusion time of the current journal had been missed. Such papers would be included in the next issue as well as in the supplement, so the price of the supplement was much cheaper than that of normal journals. And this kind of supplement was very suitable for a mage like Angeli who simply wanted to learn about the frontier theories of other studies.

He spent five silver coins to buy the supplement to the Astrologer Monthly, which was quite a bargain. After all one had to pay a gold coin for the current Astrologer Monthly.

When Angeli got the supplement, he immediately opened it and read it.

He was interested because one of his old classmates was engaged in astrological research, and Angeli had heard some theories of Wilder Regens from that old classmate before. Moreover, the tone of his classmate at that time was quite sarcastic.

"If the trajectory of the stars is not a perfect circle, then this is too strange. According to His Excellency Alberton's three laws of motion, can the speed of the stars change every moment? I wouldn't just believe it before it was proven, even if he is a high-level mage." This was what his old classmate said at that time.

Angeli didn't know much about this aspect, but the school textbook knowledge also used a perfectly circular orbit to solve the problem of the orbit of the stars, which could simplify many models, so he also agreed to his old classmate's opinion at that time.

When he got the supplement, he glanced briefly and saw the polar coordinate equation used by Wilder.

This method of establishing a coordinate system was unheard of by Angeli, but once accepted, it was very intuitive.

The calculation process of the derivation was not complicated, and Angeli could understand it after a little thought. Then, the three conjectures were proved one by one, and the process was so smooth that even Angeli, who did not deal with mathematical calculations on weekdays, could understand it clearly.

"It's really an ellipse..."

Angeli sighed softly after reading the proof process.

Although this was contrary to intuitive feelings, the proof process of this paper was flawless, well-founded, and convincing. If Angeli was a reviewer, he would have given a very high evaluation.

From now on, the knowledge of the movement of the stars would be mastered by mages, and they were stepping much closer towards the truth. Angeli had no doubts about the importance of these three conjectures, no, it should be called the three laws of Regens now, in the future astrology.

He couldn't help thinking of the previously reviewed paper exploring the combustion reaction. As far as Anglii knew, its author Reiner Ian Gray was the winner of the Hohenheim Gold Cup Award of Mercury Balance this year. His first paper was a huge breakthrough, and his second article directly rewrote the history of alchemy, and such an existence must be rare in a century.

But he was still hovering before the threshold of the Fifth Ring, unable to find the direction of promotion for a long time.

Angeli shook his head. He suddenly remembered the polar coordinate system mentioned in this paper. This coordinate system was very special, and according to Wilder, it was an unpublished paper from another mage. Angeli turned back to the reference chapter to see who could come up with such a wonderful idea.

However, when Angeli saw the polar coordinate paper, he felt as if he had been struck by a lightning bolt, and he froze in place.

Because the author's name was clearly written there, and it was Reiner Ian Gray! ！ ！

"Are you kidding me?"

Angeli couldn't help exclaiming.

The man first overthrew the four basic elements theory and established a new combustion system. And now, he even created polar coordinates, which indirectly helped a high-level mage successfully prove three ground-breaking conjectures. This Reiner Ian Gray would surely become a middle-level mage in twenty years' time.

It was really hard to imagine that such a person was just a mage apprentice now.

Being in the same era as a genius would always make people feel powerless, and Angeli could only comfort himself by telling himself that he was the first to discover the value of Reiner Ian Gray's thesis.

He walked out of the bookstore, opened his umbrella, and walked into the rain, still holding the supplement to the Astrologer Monthly.

Absentminded, Angele came to the agreed restaurant but found that several of his friends were also a little depressed.

"What happened?"

Angeli asked Hans. The Monthly Alchemist Griffin founded by his friend became famous because of the publication of Reiner Ian Gray's first paper, and the sales volume and number of submissions had increased a lot.

Before the others could answer, Angeli saw the supplement of Astrologer Monthly on the table, and instantly understood why they would look like this.

Angeli looked at Luan, who was sitting on the side. The fourth-ring mage of the astrology study was absent-minded. Obviously, although it was not enough to shake Luan's cognition greatly, he who believed that the trajectories of stars were perfectly round in the past still suffered a big blow.

"It seems that you have also seen that paper."

Hans smiled, feeling a little helpless.

"Unexpectedly, this Reiner Ian Gray had such an achievement in mathematics, it seems that it is indeed a fluke that we were the first journal that published his paper."

Everyone was silent, a sense of powerlessness enveloped the heads of these mages, and only Angeli mumbled to himself when he heard the rumble of thunder in the distance.

"It's going to rain heavily."
