Matthew traveled to "Harry Potter", only to find that the world was facing the invasion of various foreign evil gods:

The "Dimensional Devil" that rules purgatory, the "Eyes of the Abyss" that dominate the spirit world, the "Paradox Devourer" that occupies the void...

There is also the "Blood Lord" who stole his chance to travel through time and whose strength has undergone a qualitative change...

There are suddenly many evil cults in the world. They are the root of the old beliefs and the anchor point for the invasion of foreign gods.

Fortunately, the system has awakened an incredible wisdom!

Yes, you read that right! The system has given itself a cheat code!

And as the host...Matthew can completely skip the comprehension steps and directly obtain the results of comprehension!

What does your understanding mean to my understanding? We just have different divisions of labor.

Many years later, when many evil gods were willing to burn the world to death in order to descend upon Hogwarts:

[You have come into contact with the origin of the laws of space. Due to your extraordinary understanding, you have gained the right to manage the crystal wall of the world.]

[You watched the world that was about to fall. Due to your extraordinary understanding, you mastered the endless world destruction chain.]

You can figure out the system, and leave Hogwarts to me!

Looking at the system prompt, Matthew announced domineeringly:

Evil God, get out of my Hogwarts!

…

Dumbledore: Wait, your what?

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?"

Hermione (deep breath): "Hermione, you have to calm down!" "Ding! Silver treasure chest 1!"

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

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

Black: "Professor Snape, do you want to eat hot pot together? It's delicious!"

Snape: "This is my cauldron! How dare you! Hufflepuff will be deducted 50 points!" "Ding! Diamond treasure chest 1"

Black: "Professor, my last name is Grindelwald."

Dumbledore: "Huh? What did you say your last name is?" "Ding! Supreme treasure chest 1" Black

: Xiaotang, where is your nose?

Voldemort: Avada...

...

Black: "I'm just a little badger who wants to become stronger, what bad thoughts can I have?" (Spreading hands)

Edward Bedwell, who traveled to the wizarding world of Hogwarts, found himself a descendant of one of the Arthurian Knights of the Round Table. Not only that, but as long as he abides by the knightly virtues, he can gain the corresponding power. Humility and restraint allow him to be absolutely focused. Treating people with sincerity allows him to distinguish between truth and falsehood. The Weak can make him perceive all things. ...... Following the ancient knightly virtues, inheriting the will of his ancestors, studying the "Handbook of Magical Knights", Edward, who entered Hogwarts to study, practiced his own knighthood at all times. He was humble, sincere, and compassionate, and was well liked by his teachers and classmates. He was fearless, unafraid, and impartial, and the dark wizards were feared in front of him. He changed Slytherin and changed Hogwarts

"Don't put all your hopes in the 'savior', let me carry the burden!" "Believe me, there is nothing to fear from Voldemort, he was never our true enemy!" Ethan Vincent, winner of the 2008 World War II Award

His students always like to call him, "the one who fought in Hogwarts", "the terrifying instructor who conducts military exercises in the school every year"...

——

And his legendary story will start from the summer of 1980 when Voldemort had not disappeared.

——

My name is Anduin, I live in the villa area of ​​Godric's Hollow, I don't smoke, I only drink a little, I won't insist on winning over others, and I won't create enemies that give me a headache or keep me awake at night.

However, if I really have to fight, I won't lose to anyone.

Soar into the sky with the giant dragon of the Black Forest;

learn the fairy magic in the Fairy Garden;

meet the goddess of luck at the Fountain of Good Fortune with the brave;

combine the three holy relics into one in the face of the god of death;

in a world where wizards exist, are fairy tales the fantasy of genius or embellished history?

Through the mist of history, across the boundary between this world and the next.

Avalon, please show the truth of the world to the wanderers.

"My dream used to be to become a best-selling fairy tale writer in the Muggle and wizard worlds."

The reporter from the Daily Prophet raised the microphone, "What about now?"

"I have written my life into a fairy tale that I am most satisfied with... Look, whether it is Muggles or wizards, is there anyone who can refuse my story?"

[Slytherin][Hermione is the only female protagonist][More rigorous: After living in another world for ten years, the protagonist barely remembers a little about Harry Potter][Not a system]

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...

If Dumbledore had not defeated Grindelwald.

If the war between wizards and Muggles really broke out.

If the finger witch that the faded one failed to meet was reborn in the body of an 11-year-old wizard girl.

My name is Hermione Granger, and I will rebuild the magic circle of this broken world.

(Contains secondary settings, rational discussion)

Edward traveled through time again and came to a mysterious world.

From then on, there was a stranger here who could travel between the two worlds regularly.

So, what will he bring to both worlds?
