"Then we can't just do a first-year outline of the history of magic," Joel quickly found a more important point, "We'll have to make the other four grades as well." ”

"It's more popular to make a series of books, and as long as they buy the first book and benefit a lot, they will buy the second and third books!" Joel paced back and forth in the dorm room, looking excited.

Sergei shrugged his shoulders, "Then the first-year outline of the history of magic that we made will not be suppressed first?" ”

“…… Hair! Joel said, "But we have to speed up and put together an outline of the history of magic before OWL!" ”

After the OWL exams, Hogwarts no longer has restrictions on compulsory subjects, and the vast majority of students will not continue to take the history of magic in the sixth and seventh years, and no students will take this course means that there is no market.

Eddie also rushed back from the common room, took the History of Magic Outline and read it twice, "No problem, I think those lazy students will like this outline!" ”

"The pricing is there...... 1 Galleon, how's that? Joel pondered for a moment, "Do you think it's reasonable?" ”

"Almost, even a book like "Theory of Magic" will sell for 2 Galleons, and "Advanced Potions Making" will sell for 9 Galleons a copy, and it is not expensive for us to buy 1 Galleon." Eddie is price sensitive.

After coming to the wizarding world for more than a month, Joel found that the books sold here were extremely expensive, and the average wizard in the wizarding world only earned about 50 Galleons a month, but a set of spell books (ranging from 3-7 copies) sold for 20 Galleons, which is equivalent to 40% of a wizard's income, which is ridiculously expensive.

Compared to those books, 1 Galleon's outline of the history of magic is also a good deal.

As long as you pay 1 Galleon, you can get a decent score for this year's History of Magic score, and you don't have to endure the reprimand of your parents, which is a great deal to think about.

Later in the evening, Joel asks Bobby the Owl to fly to the Book Stationery store in Diagon Alley with his belongings to buy a few quills for automatic writing.

For these books, the copy spell does not work.

The Copy Charm essentially uses magic to create an identical clone of the original object, but this spell cannot be used on food, money, or living things, and in Joel's understanding, it tends to be more of a camouflage, it simply uses magic to create the shape of an object, and after the magic dissipates, it will turn into nothingness.

When Sergei made the landlord's manuals before, these manuals could only be kept for 3 days, and the manuals would disappear after the magic disappeared.

If books can be copied with the Copying Charm, then what textbooks do they buy, not even the printing companies in the wizarding world.

They now have no contact with the printing press, so they can only use the most modest way - automatic writing with a quill pen to copy letter by letter.

This kind of automatic writing quill costs 2 Xi Ke a piece, the quality is not high, and there will be a lot of typos when writing, and they have to proofread carefully.

Sergei was tired of taking on this errand, because he could not organize the outline as fast as Joel, and in this text-oriented task, Joel made full use of the learning experience of his previous life, and was clearer than his ideas.

Three days later, Eddie left the dormitory with the ten outlines of the history of magic that he had made in advance, and within a short time of arriving in the common room, he sold 8 copies, one for each of the eight new female students in Ravenclaw, and everyone was not stupid, and they could see how much this 100-page booklet was worth.

As long as you buy this booklet for 1 Galleon, memorize those key concepts, and complete the exercises of previous years, you can get an E (Exceeds Expectations) score.

Doesn't it smell?

Most Ravenclaws care about grades, they don't really love a subject, they just don't want to be left behind.

There were also many senior students who were excited to ask if there was a syllabus for the history of magic for the higher grades, and Eddie responded one by one, lying to the public that Joel and Sergei had already made a template, and they were waiting to copy a few more copies before he could sell them to them.

In an hour's work, ten outlines were sold out, which made Joel and the three even more happy.

Alan offered to help them find a printing shop, and wrote overnight to trust Alan's grandfather's relationship, and they found the Silent Printing Company as their printing party.

They had made an appointment with the printing company to meet on Saturday, and this time the four of them left the castle through the Cyclops Witch's Passage, arrived at Hogsmeade, and then took the Knight Bus to Diagon Alley.

After a bumpy ride, they reached 18A on the south side of Diagon Alley after ten minutes.

They were received by a fat man who looked like a walrus, and after seeing the template provided by Joel and the others, he gladly accepted the deal.

"We charge 1 cy for printing 300 copies at a time, and we charge 25 copper nats for more than 500 copies." The fat man's voice is like a bell.

"Isn't it okay to have less than 300 copies?" Eddie asked.

The fat man hesitated for a moment, a little embarrassed: "You know, if the printing volume is too small, it will be difficult for us to recover the cost, so we will have to charge a higher fee." ”

The number of first-year students at Hogwarts is not large, more than sixty people simply cannot absorb such a huge print volume, and the outline of the history of magic for the remaining four years is even more distant.

"You didn't even think about spreading the book to other countries?" The fat man helped them come up with an idea, "There are indeed too few wizards in England. ”

Joel's brain was spinning, and this outline of the history of magic focused on the founding of Hogwarts, and of course part of the history of magic in Europe......

He was able to draw a picture of the gourd and make an outline of the history of magic from two other schools of magic in Europe, Durmstrang and Beauxbatons.

But there was a real conundrum before him: although there were some books in the Hogwarts library that dealt with the history of the founding of the two schools, there were certainly no questions for the history of magic exams in the two schools.

With only the key concepts and no mock exercises, the usefulness of the History of Magic review syllabus will definitely be greatly reduced.

They arrived here with hope, but reality hit them in the face.

Joel took a deep breath, an idea flashed through his mind, and he whispered his plan in Sergei's ear.

"There seems to be some doability, too." Sergei pondered for a moment and nodded.

Under the pretext of going back and thinking about it seriously, they left the Silent Printing Company and came to the streets of Diagon Alley.

"What did you just say to Sergey?" Alan was a little curious.

"We'll need your help next." Joel stepped forward and grabbed Alan's robe, his eyes genuine.

"Huh?" Alan didn't know why, and Eddie on the side was also confused.

"We're not just going to have to make a review syllabus for the history of magic, but we're going to have to make syllabuses for other subjects as well! It's time to show off your potions talent when you take over the Hogwarts textbook market, Alan! Joel spoke out about his plan.
