The commotion caused by Reiner spread quickly after the exam, but none of the three people involved publicized it, so everyone only knew that Reiner's spell had damaged the obsidian slab of the test, and as for the details, there were different opinions.

But none of this has anything to do with Reiner and the others.

They returned to the hotel after their exams, where Mr. Osborne invited them to a celebratory feast, and the next morning, Reiner set out on his journey back to school.

It was already dusk when he arrived at Crescent Academy, but the affairs that had fallen in the past few days did not give Reiner room to breathe, and the alchemical creatures of the school immediately handed Reiner several letters.

He simply ate the sandwich and opened the first one.

This is a paper review letter from the Rainbow Tower.

Dear Reiner. Mr. Ian Gray, for your paper "A New Coordinate System and Its Ellipse, Hyperbola, Parabola and Other Curves in This Coordinate System", the review committee made the following review after careful review:

The research of mathematics and physics in this paper is groundbreaking, the polar coordinate system established by this paper can effectively solve the curve problems that frequently occur in the construction of spell models, the derivation and induction of several common curve function equations are rigorous and detailed, and its thinking method is worth promoting, and the optimization effect of several spell models is obvious, which has great reference value.

If the paper is approved, 30 audit points will be awarded.

"Thirty ......"

Reiner put down the letter, and although he knew that the number of award points for papers on mathematics had not been high, thirty seemed a bit too little.

It is true that thirty academic points is a very rich reward for an apprentice, but Reiner now has three hundred and fifty original academic points in his hand, which means that his potential value is already more than three thousand points, which is indeed insignificant in comparison.

But no matter how small it is, it's meat.,Academic points not only have a significant correlation with the evaluation of schools and individuals.,Materials and magic involving middle-level spells and above can only rely on academic points to redeem.,It's no problem to accumulate more now.。

Of course, these are all introduced by Reiner to other mages, when entering the middle level, the money in the world has lost its meaning to the mages, involving the casting materials of intermediate spells, the papers and monographs that record the middle level magic, including the right to use some half-planes, all need to consume academic points, so to speak, academic points are the gold of the magic world.

"Forget it, it's just a gesture anyway."

Reiner didn't dwell too much, the theory of mathematics is important, but as many mages think, mathematics is just another tool in this world, and the advanced mage is like a computer with huge computing power, or the kind that comes with matlab, even if there is no optimized algorithm, it can reach the end by exhaustion, and mathematics in many cases only plays the role of induction.

This point, Reiner has deeply realized after inscribed the spell model in his heart, he has not yet officially advanced, only the quasi-one-ring level, but for most of the high-order equations can already be solved in a few seconds, Reiner does not know if other people are like this, but at least he is currently a humanoid calculator, and the high-level mathematical formulas have lost their meaning to him.

Putting the letter away, Reiner picked up the other three letters.

This was sent to Reiner by the Alchemy Atelier in other provinces, and they were like Mr. Osborne, hoping to obtain the exclusive rights of Crescent Coke in their own province, which was also the effect of Reiner's previous publicity, he would set up an exclusive agent in each province, authorized to be responsible for the distribution of Crescent Cola, and he only needed to contact these agents.

These letters were accompanied by Reiner's requested financial reports for the most recent year, which Reiner used to determine whether the other party was worthy of authorization.

Nowadays, Crescent Moon Cola is already a hot brand-name product, and the mage card has also been updated to the third edition, with a total of seventy copies, in fact, since the third edition, Reiner has recruited a group of painters from the outside world to create the mage card with Xia Luo's painting style, which has also reduced the burden on the student in disguise.

Antoine, on the other hand, was busy improving the production line, and he had already set off for the two alchemy workshops in the Rainbow Tower, which were authorized to use the mercury balances, to learn advanced production techniques, and perhaps after years of stagnation, Antoine would be able to see hope of promotion again.

It took about an hour to review the three letters, and Reiner stretched for a moment before looking at the third.

This letter was obviously different from the previous ones, the pale yellow cover was elegantly made, turned over, and the coat of arms of the shining stars on the wax seal was also something Reiner had never seen before, and there was a small package along with the letter, not sinking, but like a book.

On the envelope, in thick and steady font was written "Kingdom of Aster, Province of Ammonay, City of Priest, Crescent College, Reiner. Ian Gray received the text", and the sender was "Wilder. Regens".

"Wilder. Regens? ”

Reiner vaguely felt familiar with the name, and he examined the magical signature on the letter, revealing that it was the coat of arms of the Stargazers.

"Stargazer...... It's supposed to be an astrological mage organization, right? ”

Talking to himself, Reiner opened the letter and read it carefully.

It took a long time for him to put down the letter and let out a long sigh.

"I only thought that the three laws of kinematics had been proposed, but I did not expect that the three laws of planetary motion had not yet been born."

This letter is a thank you letter from the high-ranking mage Wilder to Reiner, thanks to Reiner's polar paper, Wilder successfully verified his three conjectures, obtained feedback from the world, and was about to advance to the Nine Rings, just one step away from the legend, and that package included the Astrologer's Monthly Supplement.

Because on Earth, Kepler's three laws preceded Newton's three laws, Reiner subconsciously thought that someone had already taken the lead, but he didn't expect that it was his polar thesis that drove Wilder. Regens's validation.

However, Reiner thought about it, to verify the three laws of the planet's rotation requires a large amount of observational data, according to Wilder, he also got a lot of data from his own teacher, plus his own decades of observations, to get those three conjectures, so even if Reiner knew these three laws, he was a little powerless.

The feedback of this world is not simply written out of formulas, but requires an understanding of its essence, and an inductive summary after a large number of experiments, just like Reiner knows the mass-energy equation, but if it is not supported by experiments and pre-theories, it is just a formula.

On the other hand, Reiner thought that the letter from Lord Wild expressed his gratitude to Reiner, which was invisibly equivalent to the other party owing him a great favor, which should be able to come in handy in the future.

"Why don't you let him be the spokesperson for Ian Gray's textbook?"

Reiner didn't think about it, put down the letter, and opened the last one.

Surprisingly, however, the letter came from someone Reiner had never dealt with.

Chester. Christine, Dana's uncle.
