The two of them smiled at each other, recalling the seven years they had spent in Hogwarts Castle, running with their friends in the grass in the sun, their slightly raised school robes and youthful smiles on their faces.

The two of them have known each other since school, and after graduation, they both married into pure-blood families, and after giving birth to children, the trivial matters of life gradually smoothed the corners of their mouths, and although they were carefully maintained, the subtle wrinkles at the corners of their eyes still revealed that their age was not small.

The two of them were very curious to see this set of teaching materials, and planned to buy a set for their two children who had just entered the first grade and had no interest in herbal medicine.

"Hello, how much does this book cost?" The lady called a clerk.

"2 Galleons," the clerk didn't raise his head, and piled up the stack of astronomy courses in his hand to the door of the store, "If you want it, you have to buy it quickly, I guess it will be out of stock tomorrow." ”

When the two of them heard this, they looked at the people in the bookstore, and hurriedly found out all the courses of various disciplines, and took out their pearl packets to go to the counter to pay the bill.

There are many more parents who plan to buy a complete set of courses for their children, and who doesn't want their children to be better at homework?

The teaching materials produced by CLBT obviously broke their cognition, and everyone thought that the curriculum of the magic school only needed textbooks, but they didn't expect that there would be tutoring materials outside of class.

Parents also graduated from Hogwarts and entered the society, and although most of the knowledge they learned in school was returned to the teachers, they could still see the excellence of this textbook.

When they were in school, they didn't have so many exercises and analysis, and their homework was usually small essays, and they were crammed into the exam room before the final exam.

Now that the curriculum is fully understood, children no longer have to be as unprepared as they were back then, and they will not look anywhere, and their academic performance will of course rise steadily.

2 Galleons can make children one step ahead, and parents are willing to pay this money.

The 300 textbooks sold out over the weekend, not only for parents of first-graders, but also for many parents of students who are in the year of OWL and NEWT.

Many children return home during the Christmas holiday and just want to have fun for a few days, but they find that their parents happily take out a set of tutoring books that they have never seen before, and let themselves read it before the exam.

Picking up the counseling book in my hand, I saw four big words: CLBT.

Which neuropathy is this out of the book?

The children gritted their teeth but had no choice but to open the tutorial book and read it.

After reading two pages, the children found that the key points indicated in these tutorials were very helpful to their learning, especially the analysis of the exercises, and the templates of the subjective questions were standardized and detailed.

Joel also left two sets for the Weasley siblings in the Burrow, and during the two months they met in Tumbledown Alley, they exchanged letters frequently, and interestingly, Ginny and Ron did not know that Joel and Sergey were already studying at Hogwarts.

This made him look forward to seeing each other again.

After the 300 textbooks were sold out, the manager of the Blotted Bookstore sent a letter to the four of them, bearing the seal of the Ministry of Magic.

Taken apart, it is a copyright certification certified by the British Ministry of Magic, which proves that the CLBT magic course sold on the market belongs to the four of them.

After getting the copyright certificate, the Lichen Bookstore sent another order request, and the Silent Printing Company was also happy, and no one hated the money.

Everything came so quickly that during the Christmas break at Hogwarts, the manager of the Blotted Bookshop asked the four of them to meet.

"This is Geselda Marchban of the Ministry of Magic, the head of the Ministry of Magic's Wizarding Examination Authority, and a member of the Wizengamot (the highest court of the British wizarding world)." The manager of the Blotted Bookstore introduced the four of them to the lady sitting next to them, who had gray and old hair and looked much older than Professor Dumbledore.

"That's what I told you before, members of CLBT."

Lady Marchiban had a look of surprise on her face, and she looked at the four little dots sitting across from her, "Is that the full explanation of this magic course you wrote?" ”

The four looked at each other and nodded.

"It's amazing...... "Marchiban sighed as he looked at the four children who were only eleven or twelve years old, "how did you come up with this idea?" ”

The three of them turned their gaze to Joel.

"Well, I found that Hogwarts students are generally not very interested in the history of magic and wizardry, but it is a compulsory subject for the OWL exam, so I thought about how to save students revision time and improve their grades." Joel was calm.

"It's an extraordinary idea," Ms. Marchiban said, staring at his face, "very bold to try......

"The market proves that your idea is very successful." Mei Zizi, the manager of Lichen Bookstore, said that this year, he was able to get a lot of year-end bonuses from his boss with this set of teaching materials.

"I help them save time, and they deserve to be paid, and rightfully so." Joel shrugged.

Lady Marchiban laughed, "Of course, no one is going to have trouble with Kim Galleon. ”

Everyone laughed in unison.

"Let's get down to business, I'm here to discuss something with you on the behest of Mr. Cornelius Fudge, Minister of Magic," Ms. Marchiban crossed her hands, "and we intend to export some of your teaching materials to the United States." ”

"Really?" The four of them are happy.

"You can be involved in the modification process, but the Ministry of Magic has a requirement." Ms. Marchiban curled her smile.

"This set of magic courses fully explains all overseas income, and the Ministry of Magic will take 30%, of course, after this 30% of the income is handed over to the Ministry of Magic, we will no longer tax this set of books."

The four of them looked at each other, and 3% of their overseas income was not a small number to think about.

"Can we discuss it before making a decision?" Joel spoke.

"No problem," said Lady Marchban, standing up with a shudder, "and tell the manager of the Blotted Bookstore that it was a pleasure to meet you four wonderful children today." ”

After Lady Marchbon left, the manager of the Blotted Bookstore breathed a sigh of relief, "I suggest that the four of you agree to the Ministry's request. ”

"But 30% is a bit too much." Eddie was a little unhappy, this set of books was originally for the four of them to divide the income, and each of them received 25%, and the intervention of the Ministry of Magic was equivalent to one more person's money.

Sergei also showed a little dissatisfaction on his face, while Alan and Joel pursed their lips and did not speak.
