Kevin traveled to the world of Harry Potter and grew up in an orphanage without ever coming into contact with magic. It was not until he was 11 years old that he finally received the admission letter to Hogwarts.

Reborn, he just wants to enjoy this magical journey, but as time goes by, he can't help but get caught up in it...

Snape: Kevin? Humph! Just a cocky brat with a bit of talent.

Dumbledore: Kevin is such a good boy who would go to great lengths to help his friends.

Voldemort: Kevin, this unethical and despicable villain! He has attacked me with a crowbar every time I die!

[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...

In the magic world a thousand years ago, he traveled with four teachers for seven years. Ryan found himself back in 1991, back to the orphanage he was familiar with. After three days. He saw a pure white owl flying towards him with a Hogwarts admission letter in its beak. So Ryan knew that he would return to the Hogwarts that was familiar yet unfamiliar to him. "Mr. Ryan Elias." "Dumbledore called you the most outstanding graduate in the history of Hogwarts, the Dark Lord regarded you as his greatest enemy, and the dark wizards called you a wizard destined to be great. For these titles..." "Of course." Ryan answered calmly with the answer that should be given. "I approve of it all." Be it potions, duels, spells, alchemy, the dark arts, or even cooking and pranks. "Of course I will always be the best." Because he...

Wade: I only studied at Hogwarts for seven years, which means 266 weeks excluding holidays! Even if I can finish a book in a week, 266 weeks is only 266 books! How many magic books are there in the Hogwarts library? Thousands of them! Time is running out, how can I not seize the time to study? ! I will never allow anyone to destroy my learning environment - not even the Dark Lord! No, no, no, I don't just love knowledge. I'm just greedy.

On the day he crossed the world of Harry Potter and received the admission notice, Ethan awakened the achievement system. As long as he made the corresponding events, he could get rewards.

With three million gold, he has achieved the achievement of [hegemony and wealth can rival the country].

Get the blood of magical animals and achieve the achievement [I'm not a human].

Use Avadaso's life to kill 100 wizards and achieve the achievement of [Gnawing Big Melon Lover].

......

On the day of graduation, when Ethan was seamlessly appointed Minister of Magic, the reporter of The Prophet's Daily asked:

"Mr. Adrian, as the youngest and best Minister of Magic in history, I heard that you have been famous for Hogwarts in the first year of admission, won the Merlin Order Medal in two years, and directly overturned the professor in three years... I don't know why you have achieved such dazzling results?"

Ethan Adrian spread his hands: "I really want to make progress!"

Rowling travels through the world of Harry Potter and awakens to become a necromancer.

Having escaped Azkaban twice, he is famous (and infamous) in the wizarding world.

But he was hired by Hogwarts as a professor of Defense Against the Dark Arts.

Dumbledore: "Letting Rowling become a professor at Hogwarts is the best decision I have ever made in my life. But Rowling, why are you sitting in my seat?"

Snape: "You are definitely the next Dark Lord. I will keep an eye on you. Wait, why did you expel me?"

Professor McGonagall: "Rowling, I've told you many times that Transfiguration can't turn your pile of skeletons into a catgirl!"

...

Many years later.

Some people call Rowling the greatest wizard in the wizarding world after Dumbledore.

Some people also say that Rowling has influenced the atmosphere of the magical world and is a sinner of the magical world!

Some even say that Rowling becoming the headmaster of Hogwarts is a disgrace to Hogwarts!

Rowling, surrounded by the Scourge, sat on the golden chair in the Hogwarts Great Hall, looking helpless:

"How did I, a prisoner of Azkaban, get hired as a professor at Hogwarts and eventually become the headmaster?"

"It can only be said that a person's fate..."

Adrian Wisen, who traveled to the world of Harry Potter, didn't have any big ambitions. As a professor at Hogwarts, his daily routine is to take care of children, farm, and cause trouble for the elderly headmaster.
