All things are three at Hogwarts

Unlike the Gryffindors who eagerly look forward to the Defense Against the Dark Arts class, the Ravenclaw students are very calm.

The only thing they need to worry about is that Professor Moody will cause trouble for Allen because of his original actions.

When the bell was about to ring, the little wizards of Ravenclaw were already in place. They took out their own Black Magic: Self-Defense Guide and waited, and the atmosphere was extremely solemn.

Soon, they heard Moody's distinctive thumping footsteps coming down the corridor. He walked into the classroom looking weird and scary as usual. They could just see his claw-like wooden foot peeking out from under his robe.

"Put these things away," he said gruffly, walking to the edge of the podium with crutches, and sat down. "These textbooks. You don't need them."

The students put their books into their schoolbags and exchanged glances with each other.

Moody took out the roster, shook his head, brushing his long gray hair away from his twisted, scarred face, and began to roll the roll.His normal eye moved down the list, and the magic eye kept turning around, staring at each student who answered.

"Alan Harris," he growled.

"Arrived." Alan stood up and responded calmly.

Moody's magic eyes suddenly stopped turning and focused on Allen. That unblinking look was even more terrifying than when it was spinning crazily.

The classroom was extremely quiet.

Allen stood patiently for a long time and found Moody staring at him like a wax statue. He felt strangely like he was being punished to stand.

"Professor Moody, my mother and sister both worked at St. Mungo's Hospital for Magical Injuries. Do I need to reserve a high-end bed for you?"

Allen smiled, his tone extremely polite.

"Or, are you under too much mental stress? Do you want me to convene a general meeting of shareholders and apply to the Ministry of Magic for a free diagnosis of your mental condition?"

With a puff, Michael couldn't help laughing.

Allen's words seemed to break the spell, and the extremely quiet and unusually oppressive atmosphere in the entire classroom disappeared.

Moody's magic eye resumed its movement and stared at the snickering classmates.

He coughed and continued to call names. Veins appeared in the hand holding the wand under the table.

"Okay," he said when the last student finished answering, "For the smart Ravenclaw, you should have mastered a lot of basic knowledge about how to deal with black magic animals. According to Professor Lupine, You learned to deal with Boggarts, Red Hoods, Hincklepunks, Grindylows, Kabbahs, and Werewolves."

"But you haven't learned enough about how to deal with spells," Moody said. "So, I'm going to give you a taste of what wizards do. I have one year to teach you how to deal with the dark devil. "

Immediately there was a commotion under the podium.

Moody's big, rough hand slammed onto the podium. Because he was suppressing his anger, his scarred face looked even more distorted and weird.

"Logically speaking, since you are not in sixth grade, I shouldn't tell you what the illegal Dark Curse looks like, because you are still young and cannot deal with this set of things. But Professor Dumbledore praised you greatly. With courage, he thinks you can deal with it, and in my opinion, the sooner you understand what you are dealing with, the better. If you have never seen something, how can you protect yourself in front of it? A wizard is going to give If you recite an illegal spell, he will not tell you his plans. He will not recite it to you in a frank, fair and polite manner. You must be prepared and alert."

Moody stood up with difficulty on his prosthetic leg, opened the drawer of the podium and took out a glass bottle. Three big black spiders were crawling inside.

Moody reached into the bottle, grabbed a spider, and held it in his open palm for everyone to see. Then he pointed his wand at it and murmured: "Out of Body!"

There was a moment of excitement under the podium, and the learned Ravenclaw knew the meaning of this spell.

Moody instructed the spider to flip, soar, and even tap dance, but not a single Ravenclaw in the audience laughed.

They didn't expect that Professor Moody was demonstrating the Unforgivable Curse.

"Totally under my control," Moody whispered.

"The Imperius Curse can be resisted, and I will teach you the method, but it requires a strong personality, and not everyone can master it. You'd better avoid being hit by it as much as possible. Be vigilant at all times!" He Suddenly he yelled, startling everyone.

He turned his back to the class, took out the second spider from the glass bottle, and placed it on the podium.

He zoomed in on the spider and "cut out the bones." The spider's legs all shrank up and were close to the body. It flipped over, while its body twitched violently, shaking from side to side.

Moody raised his head and scanned the class, his eyes lingering on the calm face of Allen for a few seconds.

Moody's crooked mouth twitched again, revealing a smile, "Now, the last and most powerful spell is left. Avada Kedavra... the Killing Curse."

"Avada!" Moody yelled.

A dazzling green light pierced people's eyes, and at the same time there was a chaotic sound, as if an invisible giant flew through the air. At the same time, the spider turned over and lay on its back on the table, with nothing on it. Not a scratch, but undoubtedly dead.

The Ravenclaws became uneasy. It was hard for them to imagine that they would face my class next. Are they going to cast killing curses on each other?

Alan's face also showed surprise. Just now, the wand in his hand heated up and there was a strange movement.

He took out the wand and found that the wand had grown automatically at some point, and the spider's soul was imprisoned as soon as it left the body.

"Avada Kedavra requires very powerful magical power as the basis. You can all take out your wand, point it at me, and recite this spell. I suspect that I will only get a little nosebleed at most. But that doesn't matter. I'll do it. I’m just teaching you how to recite the incantation.”

Moody's expression was somewhat complacent, and suddenly he froze, and the whole class looked at the lifeless spider on the table.

The spider that lost its soul disintegrated into pieces in front of everyone, rotted away and turned into dust.

"Avada Kedavra still has this effect?" Michael asked in surprise.

None of the young wizards here have actually seen Avada Kedavra, but there is no such phenomenon in the description in the book.

Even Moody was stunned for a moment. He instantly looked at Allen, and his intuition told him that what happened to the spider must have something to do with Allen.
