Traveling to the world of Harry Potter, Ivan Vesemir became the heir of a pure-blood family.

Adhering to the central idea of "If you can survive, you will survive", Ivan handed over the Horcrux he got to Dumbledore, detoured when he met Harry Potter on the road, lowered his grades in the exam to make the professor ignore him, take a step back and find a way out;

Arm yourself with alchemy, study black magic and learn about your enemies.

And then, he was inexplicably targeted by the boss...

"What? Why can I achieve what I am today? Ah... It's embarrassing to say, they won't let me go on, so I can only find a way to kill them all."

Hogwarts Honorary Headmaster, Eagle of Helheim, Incarnate Man, Midas Toucher, Enemy of Goblins, First Class Merlin Medal Winner, Honeydukes Candy Shop Owner——Ivan Vesemir Said.

Gilderoy Lockhart has just become Minister for Magic of the United Kingdom, and there are several uninvited guests in the office.

Dumbledore: “Minister, I have to tell you with great sadness that Moriarty Slytherin is the most hidden person in the European wizarding world!”

Lovegood, editor-in-chief of The Quibbler: “Look Minister, the Hogwarts Riots, the Himalayan Avalanche, the Gringotts Heist, the World Cup Opening, the Nurmengard Bombing, the Azkaban Defection , the Durmstrang riot, these mysteries all point to one person, Moriarty Slytherin!”

Platinum noble Lucius: “On behalf of the pure blood family, I strongly request the minister to launch a wanted request for Moriarty Slytherin! Oh, my minister, don’t look at me with greedy eyes, all pure blood money is taken by Mori Artie’s gone.”

Gilderoy Lockhart showed his signature smile: “Please allow me to introduce to you my young master, the greatest wizard of all time, the master of dawn and darkness, the master of ice and thunder, the legendary god of magic, Moriarty Slytherin!”

This is the story of a little wizard who only has magic in his heart and becomes the big boss behind the scenes in the Harry Potter world.

Wentworth Grindelwald, during his lifetime, had many star-studded titles:

The greatest prophet of our time, the successor of the Umrah party, the leader of the secret party, the heir of the Grindelwald family and – the third generation of the Dark Lord!

He filled London with black gauze, and the shamans reappeared in the wizarding world;

He established a secret party at Hogwarts and monopolized the magical talents of an era;

He and the second generation of the Dark Lord duel on the Rhine, nearly half of the Death Eaters fell;

He strolled under the tower of Nurmengard, and his followers greeted Gellert out of the tower;

In the direction of his wand, thousands of believers are marching forward.

Daily Prophet: It’s the worst of times, and he’s leading wizards to destruction!

The Quibbler: It’s the best of times, and he’s leading wizards to a new life!

Wentworth Grindelwald: I’m not! I don’t! Don’t talk nonsense!

Browder of the third generation was reborn in the world of Harry Potter.

The legacy of the previous two lives gave Browder a stronger foundation in this life.

But… the water in Harry Potter’s world is really deep!

A teenager named Evan Mason was reincarnated into the magical world of Harry Potter and goes to school at Hogwarts!

With only his knowledge of the future and great talent for magic, he takes the path towards the top of the magic world, only to realize that ever step he took, changed everything!

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”
