The false devil:

Gather the Saints to fight against the Muggles.

Occupy Britain and attack the school.

The real devil:

Destroy the world and cause great suffering to all living beings.

Elias traveled through time for eleven years and suddenly found out that he had traveled to the world of Harry Potter and was chosen by the bloodline of the devil!

You only need to gather three of the seven deadly sins: pride, wrath, laziness, greed, envy, gluttony, and ecstasy, and the power of the devil in your blood will automatically summon the devil to possess you and destroy the world!

For the peace of the world,

From that day on, Elias knew that his idle life would be gone forever...

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!

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!"

…

As a result, Hogwarts has an unattended professor.

McGonagall: "Albus, I don't think Professor Dracula's teachings are suitable for poor children!"

Dumbledore: "I have no choice, no one can fire him."

…

Draco: "My father is the school director, I will definitely let him expel you!"

Lucius slapped Draco on the head, "Mr. Dracula, Draco is childish, you must not expel the school board!"

…

This is the story of a vampire who has lived too long and is so bored that he can only find fun in the magical world.

As long as you do positive things, the relevant people may drop attributes.

"I picked up 1000 Occlumency experience points, and my Occlumency skill level reached max. I got the achievement: Spell Mastery!"

"I picked up 500 points of Potions experience, and my Potions skill level was upgraded to level 5. I got the achievement: Potions Master!"

"I picked up 1000 points of physical experience, and my physical fitness increased to level 7. I got the achievement: Tear a dragon apart with my bare hands!"

...

Snape: "Are you an expert in potions? You should be the one to take the potions class from now on!"

Dumbledore: "You can master all spells at once, and you are so positive! You are the hope of the wizarding world!"

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?"

He was at Hogwarts, and had just become a Half-Blood Prince.

On the night when the savior of the wizarding world should have been born, Harry Potter died under the unforgivable curse.

The man who made almost all British wizards dare not call him by name, regained the wisdom and ambition that belonged to him from the Horcrux.

Darkness has completely enveloped the island of Great Britain.

Wizards are divided into high and low according to their bloodlines. Pure blood firmly holds the authority that belongs to the superior, and people called mudbloods can only be as humble as mud and trampled on throughout their lives.

The Ministry of Magic, which is supposed to enforce justice, is full of villains, and the castle, which is supposed to impart knowledge, is full of oppression.

In these dark times.

Jon Green, who came from across time, was brought into the exiled carriage that truly inherited the title of “Hogwarts”…

Originally titled "HP: I Died Early and Passed Through the World"

Faye was sickly since childhood and had to stay in the hospital ward all year round. She died when she was less than ten years old. After her death, she was bound to a system and traveled to the magical world.

Little Faye remembered the system novel that the nurse sister had read. The system always assigned various tasks, and there were penalties if they were not completed. She couldn't help but feel a little worried.

The system said: "We are a regular system, not some wild system with a punishment mechanism!"

... ...

Later, Xiao Fei's relationship with the system was indeed as the system said, free and unrestrained. He would often appear from one corner and then disappear to another.

One day, while wandering the castle, Faye saw a fluttering black robe. Having heard so many fairy tales from her family, Faye thought to herself, "Oh! That must be the most perfect wizard!" So she followed...

From then on, the black-haired, black-eyed professor who was the most feared by the students at Hogwarts had a "little tail" with a completely different style beside him...

"Little Tail" would give him his favorite Christmas presents, would accompany him quietly while he brewed potions, would tell him to love himself, and would even use his little hands to "slap" his head when he unconsciously belittled himself...
