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?

There's a legend circulating around Hogwarts: Miss Lacus's first cry gave birth to the Dementors; Miss Lacus's first nightmare gave birth to the Obscurus; Miss Lacus's first fear gave birth to the Boggart; Miss Lacus's first laugh gave birth to Peeves; and Miss Lacus's light side became Voldemort! "Hogwarts, that's all a lie!" Miss Lacus protests. "Your light has no dark, heavy secrets, only light and bright!" (A playful Hogwarts fanfiction, featuring many meme elements and some Hogwarts Legacy content. The protagonist is a lone wolf, not for women.)

At first, Aiden Winchester thought he had simply been transported to another world filled with malevolent spirits. However, an acceptance letter from Hogwarts changed his life as a witch hunter. He never imagined that he, who had always only hunted witches, would be accepted into a wizarding school. Witch hunter? Wizard? These two identities didn't conflict at all. Aiden, twirling his Kurdish demon-slaying blade, stood at the entrance to the Slytherin common room. Since dark wizards all came from Slytherin, why not start there! This book is also known as: *Three Sentences That Made the Headmaster Pay Me Ten Thousand Galleons*, *I Really Didn't Want to Be a Wizard*, and *Exorcising Voldemort Is Also Exorcism*.

In his previous life, Harry defeated Voldemort, protected the wizarding world, protected Hogwarts, and became a great wizard like Dumbledore. After a long time, when he was about to leave, he thought of the blond boy. What will happen to them after their rebirth? Harry's life will also change, and his relationship with Professor Snape will also be unusual.

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?

ps1: This book is a traditional fan work and will not completely abandon the original characters to tell the story. The heroine is Miss Justice, and she may join the Queen later on.

ps2: The path of the protagonist of this book is semi-original. He takes the path of [Apprentice] in the early stage and starts to change in the middle stage.

ps3: The protagonist is basically invincible in the same level, but he can't kill high-sequence enemies.

As a time traveler, Agares decided to stay away from Hogwarts after graduating, fearing he'd be caught up in the dangerous situation. However, his thoughts changed after he struck a deal with Arceus, the Pokémon God. Chosen by Arceus as a Pokémon ambassador, Agares decided to start promoting Pokémon among the more receptive wizarding community. Five years after graduation, Agares returned to the magic school, this time as a professor.

Leonard, an earthling, travels to Hogwarts and awakens the powers of the Seven Gods of Teyvat (wind/rock/thunder/grass/water/fire/ice), but he needs to gradually unlock them through the sacred relics of Hogwarts' underground leylines - the statue of the God of Wind in the Astronomy Tower, the statue of the King of Rock in the Chamber of Secrets, the Fountain of Wisdom in the Forbidden Forest... Each sacred relic contains a thousand-year contract between the ancient elemental wizards and Hogwarts.

As Hermione Granger's distant cousin, his wandless levitation and rock-lance combat astonished the wizarding world. Hermione, with her photographic memory, translated these powers into learnable "elemental spells," becoming his sole theoretical partner. From using wind to generate bay leaves in Potions class, to using a rock shield to block the basilisk's petrifying gaze in the Chamber of Secrets, to using lightning to split the Dementor's black mist in Azkaban, the two redefine the possibilities of magic through the complementary "wisdom and power" of the original novels.

As the power of the Seven Gods is gradually released, Leonard discovers that Voldemort's Horcrux is actually a "crystallization of abyssal energy", which can only be destroyed by the corresponding power of God's Eye - the Rock King's Spear shatters the golden cup, Wuxiang cuts off the diary with a single blow, and the Echo of Green purifies the poisonous fog... and Hermione pieces together a bigger truth from the family genealogy and "A History of Magic": the gargoyles and leyline obelisks of Hogwarts, and even the entire magical world, are all in line with the elemental laws of Teyvat.

When the final battle came, the shadows of the Seven Gods appeared over Hogwarts. The Wind God swept away the Death Eaters, the Rock God held up the city shield, and the Thunder God cut off the dark magic... Leonard and Hermione stood in the center of the seven-pointed star, weaving the fate of the two worlds with the resonance of elements - it turned out that as early as a thousand years ago, the authority of the Seven Gods had laid the foundation for the protection of the world.
