"What is the most valuable asset of Ravenclaw?"

"Wisdom."

"Then where does wisdom go?"

"Any direction, as long as we want, we can always find like-minded people in the house. Companions are our second wealth."

"Very good, that's it, we are united because we have the same aspirations. So, what is the most important thing besides that?"

Dumbledore always thought that Voldemort was the biggest threat to the wizarding world, until a vampire who had lived for more than a thousand years came to his door with the title deed to Hogwarts——

"A thousand years have passed, and the lease of Hogwarts is up!" Dracula said, "Mr. Principal, you don't want the students to be displaced, right?"

"What do you want?" Dumbledore asked solemnly.

"Anything interesting."

"This is easy to handle. I think the Defense Against the Dark Arts professor position is quite interesting!"

…

In the shadow of the green lantern, Carl tapped Voldemort's diary with a hook stained with evil despair.

"Poor lonely ghost, you are mine, come out and play, how are we going to carry out this pleasant torture?"

On the day when the owl delivered the Hogwarts admission letter, Carl was excited, but also glad that he did not choose "Harry Potter" when he copied books to make money. He was just one step away from biting into the special melon of Avada. After Professor McGonagall arrived, Carl discovered his talent (external plug-in): "Detect Minerva McGonagall, Animagus Transformation... Match Nidalee, Vastaya Xayah Transformation..."

It is understandable that they can transform into a cat, but why did Professor Snape match Viego? "Forever lost my love! Defeat with a single glance!

Voldemort: "We are all wizards. What do you mean by tearing the earth apart with your bare hands? Also, how come you are more proficient in dark magic than I am?"

Looking at the various black magic spells at the maximum level on his panel, Lynch was speechless.

Do positive things, why is the attribute explosion rate of black magic so high?

He looked at the admiring eyes of the people in the magic world:

"Although I'm very proficient in the dark arts, that doesn't prevent me from being the most positive wizard in the world. No one should object, right?"
