Calvin and Dumbledore broke up, Calvin never believed that Black would betray James Potter, but he really couldn't convince Dumbledore.

Sirius Black had defected to the Death Eaters, and even if Dumbledore had become a Dark Wizard, something had to go wrong.

Calvin returned to his office and wrote Blake's name on parchment, followed by James Potter and Peter Pedirou.

According to Dumbledore, Blake betrayed Potter and killed Peter, and if you want to prove his innocence, the easiest way to prove his innocence is to restore the truth of the matter, except to find the loopholes in the trial process that Phineas said.

But two of the three people on the parchment are dead, and one is in Azkaban, and if he wants to know what happened, Calvin has to go to one person.

Remus Lupin.

The only problem was that Calvin couldn't reach him. Since Calvin came to England, he had sent several letters to Lupin, but none of the owls could find him.

It's really strange where Lupin is hiding.

However, Calvin quickly dispelled this idea, the friendship of the four Calvin knew, if Lupin did not save Blake, it only means that he believed Dumbledore's words, in this case, he must not know too much of the truth.

It seems that the only way to meet Black is to go to Azkaban, or to find Fudge and take out his file.

But before visiting the prison on the weekend, Calvin had other things to do, such as giving private instruction to a few young wizards.

At seven o'clock on Saturday night, Harry, Ron, Hermione, Neville, and Draco arrived at Calvin's office on time. Harry and Neville were familiar, but Draco was the only one who felt a little uncomfortable.

I don't know what Professor Capet thinks, throwing me into a group of Gryffindors.

Harry, Ron, and Hermione were noticeably closer, and Draco was standing a little further away from them.

Calvin stepped out of a painting hanging on the wall and said lightly, "Sorry to keep you waiting, I just went to assign tasks to the third-year students." ”

Calvin took out three more scrolls from his sleeve and hung them on the wall, "Potter, Malfoy, you go into this classroom, Granger, Weasley, you go into the second classroom, Longbottom, you are in the last room." ”

Harry and Draco looked displeased at the same time, and Harry said, "Professor, aren't we in class together?" ”

"Of course not, Harry, teaching like this will help you make the most of your talents." Calvin explained mildly.

"Then can I take a class with Hermione and Ron." Harry made no secret of his dislike for Malfoy, which was hard not to remind Calvin of James Potter's attitude toward Snape.

"Alright, Harry, I have a reason for being grouped like this, don't bargain with me anymore."

Draco opened his mouth to say something, but remained silent.

"Malfoy, what do you want to say?" Calvin asked solemnly.

With Harry's lesson, Draco naturally didn't dare to mention the change of group, so he said, "Professor Capet, this painting is a classroom?" How do I get in? ”

"How you get into the nineth-three-quarters platform, you get in." After Calvin finished speaking, he summoned two doppelgangers, and the three Calvin walked into the painting at the same time.

Hermione and Ron walked into the second painting, and they found the scene familiar - they were standing on the edge of a huge chessboard with a giant wizard's flag, taller than them.

"This is the mechanism set up by Professor McGonagall." Ron shouted.

"You're right, Mr. Weasley." Calvin stood in the center of the board, "I heard from Professor McGonagall that you played a good game that night. ”

"So Professor Capet, what are you going to teach us? It won't be a game of chess. Hermione asked, smiling, baring her buckteeth.

"Of course not, Miss Granger, you're joking," Calvin opened his arms, and thirty-two white filaments flowed out of Calvin's arms, wrapping around all the pieces on the board, the stone pieces cracking and peeling off the human skin within.

Thirty-two chess pieces moved their bodies, shook off the stone skin that was still sticking to their bodies, jumped off the pedestal, stood beside Calvin, and surrounded him.

"Naturally, I'm going to teach you Transfiguration, and to be honest, I'm not as good as Transfiguration... Forget it, in short, I have recently realized that the level of Transfiguration is also the best in the world. ”

"Your task is to defeat these thirty-two chess pieces with Transfiguration, and when you are done, you can end my private instruction."

Ron looked at the tall and mighty, thirty-two chess pieces with sharp blades in his hand, swallowed a mouthful of saliva, raised his hand and asked, "Professor Capet, shouldn't it be done today?" ”

"Of course not," Calvin was amused by Ron's stupidity, and to be honest, of the three little ones, his favorite was Ron, "I've divided Transfiguration into sixteen easy applications, twelve intermediate applications, and four advanced applications, and it's on these thirty-two chess pieces, go learn them, kids." ”

Ron found a black chess soldier, and the soldier took out a coin and began to teach Ron a lesson; And Hermione walked up to a white chess bishop, and was just about to talk to him when Calvin stopped him: "Hermione, I know that you are a very talented little wizard, but I still recommend that you start with simple learning, and a soldier can only become a queen if he persists until the end." ”

Hermione nodded and asked, "Professor Capet, can I ask these pieces... How did you do that? Can I learn? ”

"Come to think of it, Transfiguration, Alchemy, Ancient Magic, and Potions, plus a little bit of memory magic, Miss Granger, you have a lot to learn, go find a soldier, don't let Ron overtake you." Calvin said to Hermione with a smile.

Harry and Draco found themselves in the castle's auditorium, with a large gilded stage in the middle, with Calvin standing in the center.

Harry was used to being in the world of paintings, but for the first time, Draco was surprised by everything: "Professor Cape, this is... Is this a painting, or is it another space? ”

"It's both a painting and another space," Calvin said, "and here, you're going to learn from me, to duel, or to fight." ”

"Even though you're only in the first grade, I still think proper combat is essential." Calvin waved his wand, and two delicate wooden figures appeared on the stage, "Of course it's impossible to get you to attack each other as soon as you come up, now your goal is to dodge the rope sent by the wooden men." ”

With that, the two wooden men shot a rope out of their right hands, tying Harry and Draco together.

"Tut, kids, practice well."
