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

In the year 1340 of the Shire Reckoning, one year before the departure of the Lonely Mountain expedition, the Grey Wizard had yet to visit the Shire, the Dwarf King was still forging weapons in the Blue Mountains, and the dragon still slept deep within the mountain…

In that very year, a young wizard unexpectedly crossed into Middle-earth, carrying the Hogwarts Sign-in System.

Overnight, Hogwarts Castle rose from the ground, standing tall and majestic on the lands of Middle-earth; flying broomsticks streaked across the skies, becoming a unique sight in this world.

In the wild lands, the legend of a black-robed wizard began to spread silently.

He was a friend of the Elves, a bane to the Orcs, a nightmare to the Trolls, and the lifelong nemesis of the Dark Lord Sauron.

Years later, when the Dark Lord was defeated, the Elves sailed West, and the Age of Men began—Duir, who had signed in at all corners of Middle-earth, looked toward the fabled lands in the West.

[Location: Aman. Would you like to sign in?]

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!

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?"

On this day, the first-year Hogwarts freshman, the young savior Harry Potter, learned that a fifth-grade transfer student came to his college. He asked curiously: "Mr. Linde, where did you study magic before you transferred?"

Linde smiled slightly after hearing this, "I was the chief mage in Winterhold in the first grade, studied pyroxene magic at Rhea Lucaria College in the second grade, and conducted actual combat training in Middle-earth in the third grade. Years went to Candlekeep to build their mage tower at Baldur's Gate."

"That sounds incredible, so what are your plans for this year?"

"If you want to build a floating city, you have to set up your own secret religion. Maybe you can solve a little trouble for Professor Dumbledore by the way? For example, a certain Parseltongue is not very friendly."

Traveling through the sky, Harry Potter, The Elder Scrolls, Elden's Ring, The Lord of the Rings, The Hobbit, Baldur's Gate, Esoteric Cult Simulator...

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

…

In 1976, 16-year-old Severus Snape welcomed a new life.

That year, Voldemort had not yet split his soul into seven pieces.

That year, Nagini was still hiding in the forests of Albania.

That year, Pandora was still doing wonderful experiments at Hogwarts.

That year, Ms. Rosmerta was in her prime and very graceful.

That year, Snape decided to experience this wonderful world.

In 1991, Harry Potter, who was looking forward to campus life, stood on the platform of the Hogwarts Express, accompanied by his parents, godfather, Uncle Remus and a snow-white owl, and hugged and said goodbye to them one by one. The wind blew his bangs aside, revealing his smooth forehead above his green almond-shaped eyes. He just felt that he was the happiest little wizard in the world. The last person to say goodbye to him was his godfather, Sirius Black. "Harry, remember, have fun!" Black squatted down, his grey eyes sparkling, "If anything happens, you know, just look for Uncle Regulus—" This is a story about a game geek who plays "Assassin's Creed" and travels through time to the story of Regulus Black, a relative of Harry Potter. Regulus is responsible for hard work, and others are responsible for happiness! Protagonist: All..
