Calvin's first class ended quickly, leaving the classroom soon after assigning a paper on unicorns.

But he didn't expect three students to follow him all the way to the office.

"Come in, don't stand outside the door." Calvin looked at George, Fred, and Cedric, who were sneaky at the door, and asked them to come in and talk.

Calvin sat back in his chair, and a blue cat jumped on the table, Calvin tapped the cat's head with his wand, and the blue cat split into three, and began to tidy up Calvin's clothes, tidy up his desk, and make coffee.

Calvin took a sip of coffee and said to the three little wizards who were stunned: "The civet cat given to me by the French Minister of Magic will be taught in the future class."

So Mr. Diggory, and the two Weasleys, what do you have to do with me? Is there something you don't understand in class? ”

Cedric calmly stepped back: "Let George and Fred speak first." ”

Calvin nodded, then looked at the almost identical Weasley twins.

George took out a book full of notes from his bag and said excitedly, "Professor Capet, it's really about studying. ”

"But not Fantastic Beasts." Another Weasley said.

"It's alchemy."

"We want to learn alchemy from you." The two of them placed the notebook "Simple Alchemy of the Family" and two small mirrors in front of Calvin, and looked at Calvin expectantly.

To Calvin's surprise, he picked up the book "Simple Alchemy for the Family" and flipped through it to see the notes the two had made on it.

The idea is very immature, but also very creative and has some unique understanding. It seems that the students of Hogwarts are still very interested in alchemy. Should you suggest that Dumbledore take an alchemy class?

Calvin closed the book and picked up the two small mirrors. A very simple alchemy artifact, with only two cores that can be used to transmit words and messages. But the precious thing is that this is not the content of "Simple Alchemy of the Family".

"Does anyone in your family know alchemy?" Calvin asked, leaning against one of the mirrors.

Fred and George shook their heads together, "My father would, but he didn't know that we were teaching ourselves alchemy. ”

Calvin went again to see when the book was printed, June of this year. That is, George and Fred read the book thoroughly in less than three months and invented their own alchemical artifacts without guidance. It seems that he still has some talent.

"At your age, it's already a good work, especially if you haven't been exposed to alchemy." Calvin returns the book and mirror to the Weasley brothers.

George and Fred were thrilled to hear Calvin's praise, their faces turned as red as their hair, and they stammered, "So professor, you, would you like to teach us?" Teach us alchemy. ”

A smile appeared at the corner of Calvin's mouth, as if he was calculating something. He crossed his hands in front of him and said, "Mr. Weasley, I believe you already have some basic understanding of alchemy. So tell me, what are the basic principles of alchemy? ”

"The basic principle of alchemy is equivalent exchange." Fred said quickly.

"Yes, so if you want to learn alchemy from me, you need to pay the corresponding price." Calvin looked at the twins with a smile.

"Uh, Professor Capet, if you need a golden Galleon, we'll give it to you. I mean, uh, not now, later. Or we can give you, our store later, shares. George said nervously.

Calvin smiled and shook his head, "Mr. Weasley." Sorry, I can't tell the two of you right now. I'm not interested in Galleon, and I don't want your shares in the future. ”

"As a magizoologist, I raise a large number of amazing animals. Now that I'm a professor, I don't have time to take care of these cuties.

So, if the two of you can come to me every week to help me take care of the fantastic beasts, I'd like to give you some alchemical guidance in my private time. ”

George and Fred looked at each other and said in unison, "We do, Professor." ”

"It's not that simple, Weasley. You two, when you go back, write a paper on your understanding of alchemy, and show me a new alchemical product. If my requirements are met, then I can teach you a lesson. Calvin made the last condition.

"Okay, Professor!"

Seeing off the Weasley twins, Calvin turned his gaze to the quiet Cedric Diggory, "Would you like a cup of coffee?" Mr. Diggory. ”

"Oh, thanks, no need, Professor Capet."

"Okay," Calvin put the empty cup on the table, and the civet cat next to him offered to refill it for him, "Are you here to learn alchemy, too?" ”

"No, it's not," Cedric was a little cramped, "Professor Capet, I'm more interested in your magic paintings. ”

"I taught myself magic drawing during the summer vacation and could only draw simple objects. Seeing your magic painting today opened my eyes to a whole new world. That's why I want to learn magic painting from you. ”

Calvin nodded: "No problem, the same request as the Weasley brothers." At the same time next week, show me your magic painting, and if it meets my requirements, I'll teach you how to do it. ”

Cedric agreed to Calvin, but did not leave the office.

"Do you have any questions? Cedric. ”

"Yes," Cedric nodded heavily, "Professor, I see that the fantastic beasts you drew can come to reality and even interact with us. If I'm not mistaken, under your control, these magical beasts can attack. ”

"If that's the case, then can you draw a magic spell into a magic painting, and throw it out to draw paper when you want to use it."

Cedric's statement really surprised Calvin, he thought it was just an ordinary student, but he didn't expect him to think of so much.

"Very good, Cedric," Calvin looked at him approvingly, "you are very good. In fact, the wizards of the Far East did just that.

They record spells in obscure symbols, more like our ancient scriptures, drawn in special ink on special paper, and the finished product is smaller than your textbook, which they call charms.

Ink and paper are expensive to draw spells, and the success rate is not guaranteed, so the most precious treasures of the wizards there are the powerful charms made by the master spells.

I have seen a powerful, or rather rich, sorcerer duel in the Far East. As soon as he made a move, the sky was covered with yellow paper, and countless powerful charms were overwhelming. ”

"So, Professor, do you know how to make charms?" Cedric asked excitedly.

"Charms? Cedric, you'll find out later that I can do more with magic than spells can't. Calvin smiled and drank his cup of coffee.
