(This work is a system-based work. The early stage focuses on building Hogwarts to train wizards. The middle stage allows the trained wizards to integrate into the Muggle world to establish a society where wizards and Muggles coexist. The later stage welcomes the invasion of the alien world and resists and counterattacks. The number of words is determined by the work's performance.)

For thousands of years, names like Merlin, Gryffindor, Slytherin, Hufflepuff, and Ravenclaw have illuminated the magical sky.

In the past hundred years, Grindelwald, Dumbledore, Voldemort, these names, whether good or evil, have been guiding the direction of history.

And when Kyle opened the door to magic

A floating island rises before the eyes of billions of Muggles and wizards

He knew that a thousand years later

He is a legend!

At just seven years old, Dina Avery was imprisoned in Azkaban, becoming Sirius Black’s fellow inmate.

On his first day behind bars, he discovered that "Merlin’s XX" wasn’t just an expletive—it was a real summoning ability. He could actually call upon Merlin’s powers, including but not limited to:

- Merlin’s Beard

- Merlin’s Stockings

- Merlin’s Magic

- Merlin’s Bloodline

- Merlin’s Treasure

From that day on, Dina relentlessly “borrowed” from Merlin’s legacy.

Four years later, Dina made history as the first young wizard to receive a Hogwarts acceptance letter while in Azkaban. After being picked up by Snape, he found that his home was gone.

But it didn’t matter. He was Merlin’s heir.

The scum responsible for his family’s destruction would soon face justice—

at the hands of the new Merlin, just like in The Count of Monte Cristo.

Many of the stories of the bards are not just hearsay, but also their personal experiences.

Ino thought that he would spend his future in one fantasy story after another, until one day, he received a letter from an owl...

[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...

The story begins. Ian thought he was just a little wizard with a bit of talent and a simple [plug-in]—as long as he worked hard, he could become stronger.

However, as time passed, he began to realize something.

The teachers guiding him in magic were either legendary powerhouses or figures straight out of myths.

*"Standing before you is the noble Apostle of the Maze, the Co-Spokesman of the Old Dead, and the heir personally chosen by the founder of Hogwarts!"*

What? The noseless monster wants to make a move?

He must have never heard of the original spell recorded on my Chocolate Frog’s Famous Wizards Collection Card!

Dumbledore: *"That spell…!"*

Dumbledore’s expression changed as Ian recited *"Call of the Guardian Spirit."*

Silver-white threads surged, intertwining and condensing until a familiar figure appeared, one that a certain professor had spent his entire life drowning in guilt over.

Sherlock Forrest, who had just crossed into the world of Harry Potter, did not have a golden finger and did not inherit the memory of the original owner, looked at the Hogwarts letter of appointment in his hand, and pouted.

“Just a Defence Against the Dark Arts professor.”

…

A few years later, the Daily Prophet conducted an interview with Harry Potter, one of the ten outstanding talents in the wizarding world of the 21st century.

“When was the happiest day of your life?”

There was an uncontrollable smile on Harry’s face.

“It’s the day after Professor Forrest cursed me that I would be taken away by You-Know-Who tomorrow.”

“Uh…what about the day you least want to go through?”

Harry suddenly turned gloomy.

“Every Christmas.”

“Why is this?”

He covered his face in pain, and even couldn’t help sobbing.

“Woooooo…because on that day, Professor Forrest will wish me a Merry Christmas!”

……

The book is also known as “Please Shut Up, Professor Forrest! “, “On the matter of defeating the Dark Lord, it only takes a certain professor to open his mouth”, “I’m living a life of stealth at Hogwarts, just to live a healthy and happy life”
