Hogwarts School of the Dark Arts

Hogwarts Castle was unusually quiet late at night, just like the water in the black lake outside the castle. Only a few ripples occasionally sounded when fish passed by.

Or a cat running after a fish.

Mr. Filch and his cat patrol Hogwarts Castle every night and sometimes during the day. God knows how he maintains such high energy for so long at his age.

Sometimes he could catch one or two young wizards wandering around the castle without sleeping at night, but most of the time he was doing useless work.

"Damn it! Lost me again!"

Mr. Filch turned a corner with the oil lamp in hand. His prey had disappeared without a trace.

"Library! It must be in the library!"

Muttering something to himself, Mr. Filch ran quickly towards the library without stopping, panting heavily as he ran.

Bang!

Pushing open the library door, Mr. Filch raised his oil lamp and looked around.

"Xavier, I know you're here! Come out!" Mr. Filch shouted.

His voice was not loud, but it carried far in the quiet night.

At a table not far from him, Xavier raised his head and glanced at Filch, then continued reading.

His legs were crossed on the table and he was slumped in the chair. There was a stack of books on the chair next to him. On top of the books were a plate of chocolate beans, a cup of tea and a candlestick.

"Xavier?"

"Isn't it here?"

Filch scratched his half-bald head, sighed helplessly and walked out of the library.

suck~

After taking a comfortable sip of black tea, Xavier continued reading leisurely.

After a while, the door of the library was opened again. Principal Dumbledore, wearing a nightgown, walked into the library and looked around, then walked straight towards Xavier's location.

"Maybe I should hide all the magic books that record Muggle banishing spells...or list Muggle banishing spells as magic that is forbidden to be cast in school...especially not on Mr. Filch." Principal Dumbledore He took a chocolate bean and threw it into his mouth while eating it.

"why?"

"Don't you think it was disrespectful to Mr. Filch to cast the Muggle Repelling Curse on Mr. Filch?" Headmaster Dumbledore asked.

"Is it a sign of respect to cast a Muggle Expelling Curse on a Muggle?" Xavier asked without raising his head.

"This is different." Principal Dumbledore shook his head: "Mr. Filch is a squib. He and Muggles..."

"What's the difference? Or is it just because of different origins?"

Principal Dumbledore was silent for a moment: "No, the biggest difference between them is that Squibs believe in the existence of magic, while Muggles do not believe in the existence of magic."

"You can go to an orphanage in the Muggle world and find a random Muggle child and bring him to live in the magical world. When he grows up, he will definitely believe in magic. People who live in the magical world will naturally believe in the existence of magic."

"This is an interesting research topic... What book are you reading?"

Principal Dumbledore pushed up his glasses and changed the subject. He did not want to continue discussing this topic.

"The Origin and Development of the Cruciatus Curse."

Principal Dumbledore:...

Let’s continue the topic we just talked about.

Ugh……

Principal Dumbledore sighed tiredly, pulled up a chair and sat down next to Xavier, across the chocolate beans.

"Why should you read this book?"

"Of course it's to learn the Cruciatus Curse."

"Then why do you want to learn the Cruciatus Curse? You should know that it is one of the most evil black magics, right? The reason why black magic is called black magic is because they will in turn affect the wizard's mind, making the wizard more and more crazy and paranoid. .”

"That's them, I'm different."

Xavier turned a new page, then reached out and placed his hand next to the plate of chocolate beans, palm up.

Boom~

A ball of black flame emerged from Xavier's hand.

Principal Dumbledore looked carefully at the flame in Xavier's hand, with approval in his eyes.

"Great magic, and it can be cast without a wand. Xavier, with your level of magic there is no need to learn black magic. You are already very powerful."

Xavier didn't speak, just clenched his fingers, and the flames immediately went out.

Then Xavier opened his fingers again, and the flames appeared again.

It was also a black flame, but this time, Principal Dumbledore frowned instantly.

He felt a strong malice from this flame, as if he was facing a powerful black magic... No, it was black magic!

"Love and hate are both extreme emotions, and extreme emotions are just the external manifestations of gravity and repulsion. If you are not exposed to the essence of gravity and repulsion, then naturally you can only cast those powerful magics by mobilizing extreme emotions. And I have come into contact with the nature of gravity and repulsion, and I don’t need extreme emotions to perform powerful black or white magic.”

"is it?"

Dumbledore frowned. If he hadn't seen it with his own eyes, he would never have believed that there was black magic in the world that had no side effects.

"Maybe you can see the other magic more clearly...pay attention to my emotional fluctuations."

"Okay." Principal Dumbledore nodded.

Xavier retracted his left hand and took out his wand from his pocket, pointing it towards the table.

"Call for God's Guard"

A white oriental dragon appeared above the table. It twisted its slender body in the air as if swimming in water, and "jumped out of the water" from time to time.

"Did you feel any emotion I had just now?" Xavier asked after taking back his wand.

Principal Dumbledore shook his head: "Indeed not."

"uh-huh."

Picking up a chocolate bean and throwing it into his mouth, Xavier continued reading.

Reading a book about the Cruciatus Curse, one of the three unforgivable curses, in front of the headmaster of Hogwarts School of Witchcraft and Wizardry is so exciting~

"Harry told me that you cast a very terrifying spell on Malfoy. Between you and him..."

"Oh, it's just a personal matter. Don't worry, I acted in a measured way. I was just trying to scare him... but Harry suddenly appeared and broke the atmosphere I had worked so hard to create." Xavier took a sip of tea and looked a little a little a little nervous depressed.

"Really?" Dumbledore picked up a chocolate bean: "You may not know that after you left, Harry used some tricks to liberate Malfoy's house elves. Malfoy was so angry that he vomited blood and was sent to the hospital. "

"Really or not?"

"Maybe you put too much pressure on him before, and Harry's behavior gave him the final blow."

"That's it..." Xavier put down his legs and put the book on the table and touched his chin with his hand: "It seems that after the holidays I will buy a house elf to help me deliver a gift to Malfoy and visit him. illness."

Principal Dumbledore shook his head helplessly, thinking that this is too damaging for you.
