The world didn't have to go through the hassle of publishing a book, it didn't need a book number or an edition number, Reiner just had to find a printing house and pay for a mountain of copies of the reference books, and many mages would bind their papers into a book and sell them separately after filing them with the Magical Society.

It's just that the problem of sales channels has to be solved by itself, after all, these self-printed copies do not have a fixed audience of readers like those academic journals, and it takes a lot of effort to convince bookstores to buy them, and this kind of thankless work is probably only done by some people who have a grudge against publishing books.

Reiner naturally took these issues into account, but fortunately he was not alone, and his previous experience had given him many connections, so he put aside three reference books, picked up a quill, and began to write a letter.

The recipient was Frederick. Dmitry, the president of the mercury scales, left Reiner a personal contact information that could be delivered directly to his home.

As far as Reiner knows, there are also several magic academies under the mercury scale, which focus on alchemy education, and usually the students who enter the school are the children or relatives of the members of the mercury scale, which can be regarded as children's schools.

The teaching level of these schools is naturally not bad, but even so, the level of students is uneven, and these magic academies are naturally no match for those comprehensive academies.

Reiner's purpose in writing this letter was to promote his reference book in the magic academy under Mercury Balance, and he didn't know how to contact the principals of those schools, so he simply wrote directly to the top leader.

In fact, what Frederick said at the annual meeting was not a scene, after Reiner took the mock exam, the steady middle-aged man immediately sent a congratulatory letter, congratulating Reiner on successfully inscribed a ring of spells into his heart, it seems that this high-level mage is well-informed, not Reiner can imagine.

“...... The focus is on improving the students' test-taking level, consolidating the foundation, increasing the number of advanced students, and providing more high-quality reserve forces for mercury balances......"

Reiner wrote that he first offered some opinions on the current educational problems encountered by the Academy of Magic, then recounted several teaching materials that he had compiled, and finally laid out the results of his application to Crescent Academy, and the whole letter was so convincing that even Reiner himself was impressed.

He waited for the ink to dry, sealed it in an envelope, melted the wax, and then went to the attic of the tower, and handed it to the owl to send along with an excerpt of the sample book.

When he returned to the office, Reiner found that there was already one more guest in the room.

The tiger-striped kitten, which she hadn't seen for a long time, was sitting on Reiner's desk licking its paws and washing its face, and the sun shone through the window.

I don't know where it went during this time, and Reiner almost forgot that there was such a magical cat in the school.

It quickly noticed Reiner and meowed.

"I don't have anything to eat here."

Reiner shrugged, it wasn't a meal now, and he didn't have the habit of having to eat to work, and there might only be a glass of water to drink in the huge office.

The kitten seemed to understand Reiner's words, shook his head and jumped off the table, and slipped out of the main entrance generously.

Reiner smiled and returned to his seat, only to find that the "Complete Explanation of Ian Gray's Teaching Materials" that he had put aside had been opened at some point, and he had also turned to the chapter on spell model building.

Looking around, Reiner found that the window of the headmaster's room was not open, it should not be blown by some wind, and when he thought about it, it seemed that there was only one possibility.

"Won't it?"

Reiner was dumbfounded.

......

Frederick. Two days after Dmitry received Reiner's letter, and he was presiding over a regular meeting of the mercury scales, and when he returned home, his wife was out to buy food, and his daughter had not yet finished school, so Frederick took out his heather pipe, put in a few tobacco, and wanted to enjoy the afternoon comfort, knowing that his wife never allowed him to smoke when his daughter was at home.

The pungent smell was inhaled from his mouth, spread to his lungs, and then gently exhaled, and Frederick lay in a rocking chair with his eyes slightly closed, very comfortable.

"If only another frothy Yorkshire beer at this time......"

Frederick muttered to himself, it was the city where he studied when he was a child, and the beer in the bar always had a special aroma, and it was Frederick who relied on these beers and pipes to survive for many days and nights, and finally became a high-level mage.

It's just that after having a daughter, Frederick quit smoking and drinking at the request of his wife, at least at home, he never smoked or drank in front of his daughter.

If the colleagues of the mercury balance were actually strict wives, Frederick probably wouldn't be able to be serious in front of them in the future.

Thinking about an academic question, Frederick heard a noise by the window and opened his eyes, only to find that it was a variegated owl with a package in its talons, pecking at the glass with its beak.

Standing up and grabbing a handful of crushed nuts from the table, Frederick opened the window and fed the owl as he removed the package from its talons.

Not many people knew the address of Frederick's house, and when he opened the properly sealed package, he found that it was Reiner. Letter from Ian Gray.

"Hehe, I don't know what this kid has in mind."

The previous Crescent Moon Coke was promoted by the mercury balance, and now it has become popular among the mages of the Rainbow Tower, and has gradually spread to the nobility, and the mercury balance has naturally made a small fortune from this.

Opening the letter, Frederick quickly finished reading it, and instead of rushing to conclusions, he first opened the sample books that Reiner had sent at the same time.

Although he had been away from elementary education for many years, Frederick had students of his own and quickly saw Reiner's intention to produce these materials, and he was a little surprised and amazed by the business vision of the other party.

Mages have a grasp of cutting-edge knowledge, but they don't like to make money, so many times they don't pay too much attention to how to monetize their results, and attack magic accounts for the vast majority of traditional spells, so it has always given people a feeling that magic is alienated from the general public.

But this Reiner. The vast majority of Ian Gray's creations are magical, and they are practical enough to revolutionize mages in the future.

"That's a funny guy."

Frederick laughed, and already had a few candidates in mind.
