Calvin hurried back to his office, not thinking about substitute teachers for a while. Compared to the mysteries of magic, this matter is not worth mentioning.

He sat down at his desk and wrote down all the conversations of the day, on parchment—with Voldemort, with Flitwick, with Bablin, with Dumbledore.

All four of them were people who stood at the top of the pyramid of the wizarding world, and Calvin crossed their perceptions of magic and began to reconstruct their understanding of magic.

"Where did magic come from?"

"Soul? Or is it emotion? Or something else? ”

"What is the magic of love?"

"What does Flitwick say about the feeling?"

"What did Bassida say when she felt the heartbeat of the demon?"

Calvin's head was about to blow up with these questions, and he decided to go out for a walk.

It was already dark, and Calvin was walking on the frozen ice of the Black Lake. The surrounding scenery, along with Hogwarts Castle not far away, has faded from color to black and white.

Winter is the season of thinking.

Calvin quickly discarded Flitwick and Bascida's knowledge of magic, as they were not experienced enough or were suited to a few areas.

Only Voldemort and Dumbledore's words remained.

Calvin recalled the words of the two over and over again:

"Salazar Slytherin was an amazing wizard who threw himself into magic and eventually achieved something unsurpassed."

"Lily is willing to die and use her life to keep Harry safe. This magic would protect Harry until he came of age. ”

Calvin repeated the words of the two men countless times, trying to understand the meaning of the words in all aspects. It's like a good stonemason polishing a perfect sculpture.

The long thought was carried out on an aimless walk, Calvin walked on the frozen ice, walked in the colder and colder wind, and before he knew it, he had reached the other side of the Black Lake.

Calvin turned around and walked back, and when he reached the end of the Black Lagoon again, most of the information about the conversation with Voldemort and Dumbledore was also discarded, leaving only two short sentences:

Do you have to throw yourself into magic, sacrifice? That's not enough, you have to burn everything.

The power of magic depends on how much you are willing to pay for love.

Burn everything and pay for love.

Calvin paused and looked up at the endless starry sky.

Just a little bit.

The moment the ice water flooded Calvin's head, he understood, and in the dead silence of the cold darkness, he saw the truth of magic.

Calvin stood on the surface of the lake again, and before he even had time to dry his clothes with magic, he silently said in his heart: "Faith, it is faith." Or rather, the power of believing. ”

Calvin closed his eyes and imagined the flow of magic flowing through his body gradually converging on his right hand.

Calvin opened his eyes and saw wisps of white mist escaping from his right arm and gradually flowing into the palm of his hand.

"Is this magic in its purest form?" Calvin excitedly looked at the white ball of light that jumped in the palm of his right hand.

Calvin's mind moved, and a wisp of magic power separated from the ball of light, flowing to the tip of his index finger, emitting a dazzling white light, yes, the simplest light spell experiment was successful.

Calvin controlled the wisp of magic on the tip of his index finger and slowly returned to the palm of his hand, and in the next moment, the ball of light composed of magic began to burn, as if Calvin was holding a fireball in his hand.

Immediately after, the fireball disappeared, and Calvin controlled the magic to wrap a piece of broken ice on the ice, and the ice cube turned into a huddled arctic fox in an instant.

Transfiguration. Calvin was ecstatic and withdrew the magic in the Arctic Fox, which turned into a piece of crushed ice.

This time, the magic flowed throughout the arm, and Calvin's right hand turned into a thick tiger claw.

"Ah, it's okay to deform the human body." Calvin sighed.

Calvin hurried back to his office, he had too much to experiment with.

In his office, Calvin re-condensed the orb of light with his magic, trying to blend it into the walls around him.

Succeeded, Hogwarts did not reject its own magic.

Calvin was constantly pumping out his magic powers, trying to see how far his magic could envelop.

The white aperture started with Calvin's hand and spread outwards in a circle, finally successfully enveloping his office.

At the same time, Dumbledore, sitting in the Headmaster's office, put down the quill in his hand and frowned—he had lost control of a certain part of the castle. It's just a small room compared to the whole of Hogwarts, but who has the power and who has the ability?

Calvin also frowned slightly at this time, his magic could only cover his office and the two empty classrooms next to him, no matter how much, he couldn't withstand the pressure of the entire castle.

He decided to go the other way, condensing his magic into a slender but strong enough thread to penetrate deep into the walls of Hogwarts. The magic constantly roams through the castle, feeding back everything it perceives to Calvin who is sitting in his office.

Aside from the powerful magic that prevented him from entering the Headmaster's office, Calvin explored almost every corner of Hogwarts.

Professor McGonagall is drinking tea and chatting with Professor Sprout;

Professor Flitwick is writing to his pen pal;

Professor Snape casts the Moonbloom Charm on a newly planted plant;

Professor Trelawney drunkenly drank a bottle of rum;

Professor Babling is taking off ...... Forget it, I didn't see this;

Hermione was at the school hospital explaining to her two friends the lessons they had fallen behind in the past two days;

Cedric is painting a portrait of a strange witch in the break room;

The Weasley twins are on a rampant night tour of the castle.

George suddenly tugged at Fred's arm and motioned for him not to move.

"What's wrong?" Fred asked.

"Feel like someone?" George looked around wary.

Fred took out a worn-out map and looked at it: "You are mistaken, no one is near us at all." ”

"Really?" George scratched his head, "It's better to go back early, it's not too early." ”

Calvin's magic left the castle and entered the Black Lake, where Calvin wrapped the magic thread around a salmon and swam with it.

He saw the merfolk village underwater, the merfolk raised by Grindellow. I saw the big octopus guarding Hogwarts, sleeping peacefully.

And in Hogwarts Castle, not far from the Black Lagoon, Calvin gradually withdrew the magic thread, and his eyes were clear. He pushed open the window of his office, looked at the sleeping world, and said calmly:

"I'm going to lead magic into a new era."
