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...

Traveling through the world of Harry Potter, and reborn as the flesh and blood of Grindelwald and Dumbledore, Black awakened the emotional treasure chest system!

You can get a treasure chest by making others' blood pressure soar!

So...

Black: "Review? You just learned the knowledge, you forgot it so quickly?"

Black: "What a handsome cat!" (Take out the cat toy!)

Professor McGonagall: "!!" "Ding! Gold treasure chest 1!"

*"Avada Kedavra!"*

The evil Dark Wizard cast the Unforgivable Curse.

Yet Asher, unfazed by danger, even laughed and taunted:

*"Come on! Kill me if you have the guts!"*

Then, the eerie green light struck Asher’s body—

but the one who dropped dead was the Dark Wizard himself.

*"Heh… Didn’t expect that, huh?*

*There are people under us!"*

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.

Infernal Affairs

Wormtail: You undercover guys are really interesting, always meeting in the cemetery.

Snape: I'm not like you, I'm honest.

Snape: How can I give you a chance?

Wormtail: I had no choice before, now I want to be a good person.

Snape: Okay, tell Mad-Eye and see if he tells you to be a good person.

Wormtail: That means my death.

Snape: Excuse me, I'm from the Order of the Phoenix.

Wormtail: Who would believe that?

Memento

Bertha Jorkins: Someone has been messing with my memory. At first I just forgot the afternoon, then I started to lose track of dates and what I had for breakfast…

I wanted to visit my aunt in Albania before I lost all memory of her, and Mr. Crouch was very considerate in granting me this leave.

Crouch?

I seem to remember something, a great secret.

Danger is approaching.

Adrian Wisen, who traveled to the world of Harry Potter, didn't have any big ambitions. As a professor at Hogwarts, his daily routine is to take care of children, farm, and cause trouble for the elderly headmaster. Everyone who knew Adrian Wisen also knew that he was a kind and amiable wizard. Oh, there is one important thing. Never go near those plants he grows!

Roger traveled to the world of Harry Potter.

The game started on hellish difficulty; he became the apprentice of an old, powerful, and extremely temperamental dark wizard. Just as he was cautiously serving this unpredictable mentor, he unexpectedly discovered that the bio-computer he had developed in his previous life had also transmigrated with him!

From then on, Roger's magical training began with the three Unforgivable Curses! "Analysis of the Imperius Curse complete." "Begin observing Professor Quirrell."

Years later, when the Daily Prophet was preparing to write a legendary feature on Mr. Roger Lewis, prominent figures in the wizarding world spoke out:

Professor McGonagall (with a serious expression of amazement): "Without a doubt, Mr. Lewis is an unprecedentedly outstanding graduate in the history of Hogwarts." Dumbledore (his wisdom gleaming behind his half-moon spectacles): "I must admit that no one understood the nature of magic better than Roger. Not even the four founders of Hogwarts." Voldemort (in a complex tone): "It is well known that I made indelible contributions to Roger's magical research..."

Rita Skeeter (writing furiously with her quill pen, her eyes gleaming with gossip): "Mr. Riddle, was it the summer before Mr. Lewis enrolled?"

Voldemort (lost in memories): "Sigh...that summer, they invited me to participate in the experiment, though the method was crude...If they had said it was to develop an elixir of immortality, I could have provided tremendous assistance! I wouldn't have needed to go through the trouble of finding the Philosopher's Stone...I still deeply regret missing this opportunity to return sooner!"

Joel Hemis always thought of himself as an ordinary druid. Until he was eleven, when he received a letter delivered by an owl—and from that moment on, he became a proud little magical owl. ...That school year, the Forbidden Forest welcomed a Patronus. By the time all the teachers and students of Hogwarts realized what was happening, they were already surrounded by the Forbidden Forest! Until one day, the mysterious man came knocking—Joel: "Sorry, I just want to plant trees in peace and quiet, I don't want to fight!"... [P.S.: This is a lighthearted story about going to school and happily planting trees...No need to have read the original books.]
