The commotion caused by Reiner quickly spread after the exam, but none of the three people involved made it public, so everyone only knew that Reiner's spell caused the test obsidian slab to be damaged. As for the details, there are many different opinions.

But these have nothing to do with Reiner and others.

After the exam, they returned to the hotel. Mr. Osborne invited several people to have a celebration banquet. Then, the next morning, Reiner embarked on a journey back to school.

It was already dusk and dusk when I arrived at Crescent Academy, but the matters that had been lost in the past few days did not give Reiner a room for breathing. The school's alchemy creatures immediately handed Reiner several letters.

He had a simple sandwich and opened the first seal.

This is a paper review letter from the Tower of Rainbow.

Dear Mr. Leonard Ian Grey, for your paper "Study on the Functional Equations of a Brand New Coordinate System and its Elliptic, Hyperbola, Parabola and Equal Curves" after careful review, the review committee made the following review:

The paper's research in mathematics and physics is pioneering. The polar coordinate system it establishes can effectively solve the curve problems that frequently occur in the construction of spell models. The paper's derivation and summary of several common curve function equations is rigorous and detailed, and its thinking method is worth promoting. It has obvious optimization effects for several spell models and has great reference value.

If the paper is reviewed, thirty review points will be rewarded here.

"Thirty..."

Reiner put down his letter. Although he knew that the number of reward points for papers about mathematics has always been low, thirty seemed a bit too few.

It is true that thirty academic points are a generous reward for an apprentice, but Reiner is now holding 350 original academic points in his hand, which means that his potential value has exceeded 3,000 points. In comparison, these thirty academic points are indeed insignificant.

However, no matter how small it is, it is still meat. Academic points are not only related to the evaluation of the school and individuals, but also can only rely on academic points to exchange for materials and magic involving intermediate or above spells. It is no problem to accumulate more now.

Of course, these are all introduced by Reiner after hearing other mages. After entering the middle level, the money in the world has lost its meaning to the mages. It involves the casting materials of intermediate spells, papers and monographs that record intermediate magic, including the right to use some semi-planes, all require academic points. It can be said that academic points are the gold in the magic world.

"Forget it, it's just a move to raise your hand anyway."

Reiner was not too entangled. Theories in mathematics are of course important, but as many mages believe, mathematics is just another tool in this world. Advanced mages are like a computer with huge computing power, and they are still the kind that comes with matlab. Even without an optimized algorithm, they can reach the end by exhaustion. In many cases, mathematics only plays the role of induction.

After engraving the spell model in the heart lake, Reiner deeply understood this point. He has not yet officially advanced, only has a quasi-link level, but most advanced equations can be solved in a few seconds. Reiner is not sure whether others are like this, but at least he is currently a humanoid calculator, and high school-level mathematical formulas have lost meaning to him.

Putting the letter in his arms, Reiner picked up three more letters.

This was sent to Reiner by the alchemy workshops of other provinces. They were like Mr. Osborne, hoping to obtain the exclusive agency rights of Crescent Coke in the province. This is also the effect of Reiner's previous publicity. He will set up an exclusive agency in each province to authorize him to be responsible for the issuance of Crescent Coke. He only needs to contact these agents.

These letters are attached with the financial report of the alchemist for the past year that Reiner asked, and Reiner used this to determine whether the other party deserves authorization.

Nowadays, Crescent Coke is a popular brand product, and the mage card has been updated to the third edition, with a total of 70 pieces. In fact, since the third edition, Reiner has recruited a group of painters from the outside world, and used Xia Luo's painting style to create mage card, which has also reduced the burden on this student in disguise.

Antoine was busy improving the production line. During the Lena exam, he had already set out to the two alchemy workshops in the Tower of Rainbow, which were authorized to mercury balances, to learn advanced production technology. Perhaps after years of stagnation, Antoine might see hope for promotion again.

It took about an hour to review the three letters, Reiner stretched before looking at the third one.

This letter is obviously different from the ones before. The light yellow cover is exquisitely made. When you turn it over, the emblem shining with stars on the wax seal is something Reiner had never seen before. There is also a small package along with this letter, which is not heavy, but looks like a book.

On the envelope, the text "The Kingdom of Astel, Province of Anmonet, Preest, Crescent Academy, Reiner Ian Grey" is written in thick and steady font, and the sender is "Wilder Regens".

"Wilder Regens?"

Reiner vaguely felt that the name sounded familiar. He checked the magic signature on the letter and found that it was the herald of the Stargazer organization.

"Stargazers... should be the mage organization of the celestial system, right?"

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

It took him a long time to put down the letter paper and sighed.

"I only think that the three laws of kinematics have been proposed, but I didn't expect that the three laws of planetary movement have not yet emerged."

This letter was a thank you letter written by the advanced mage Wilder to Reiner. Thanks to Reiner's polar coordinate paper, Wilder successfully verified his three conjectures and received feedback from the world. He was about to advance to the Nine Rings, just one step away from the legend. The package included the supplement of the "Astrologer Monthly" which included Wilder's paper.

Because on Earth, Kepler's three laws were earlier than Newton's three laws, Reiner subconsciously thought that someone had already taken the lead, but he did not expect that it was his polar coordinate paper that promoted Wilder Regens' verification.

However, Reiner thought about it again that he needed a large amount of observation data to verify the three laws of planetary movements. According to Wilder, he also obtained a large amount of data from his teacher, and his decades of observations were used to obtain those three conjectures. Therefore, even if Reiner knew these three laws, he was a little helpless.

The feedback from this world is not something you can get by simply writing the formula, but requires an understanding of its essence. The summary after a lot of experiments is like even if Reiner knows the mass-energy equation, if there is no support from experiments and pre-theory, this is just a formula.

On the other hand, Reiner thought that His Excellency Wilder expressed his gratitude to Reiner in the letter, which invisibly means that the other party owes him a favor and should be useful in the future.

"How about let him be the spokesperson for the full interpretation of Ian Gray's textbook?"

Reiner thought of it without any idea, put down the letter and opened the last one.

However, unexpectedly, the letter came from a person Reiner had never dealt with.
