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!

Coming to Hogwarts from a low-magic world, Moon was originally just a half-baked psychic with no talent, but in this magic school, he received the best magic education.

......

Flitwick, the spell professor: Scarlett, I teach you magic duel, not dimensionality reduction attack.

Sprout, the herb professor: Scarlett, I think you are more suitable to be a judge of the herb evaluation, not to participate in it yourself.

Transfiguration professor McGonagall: Moon, I let you study transfiguration, but not to change things that do not exist in the world!

Snape, the potion professor: You must have more potion materials, bring them, bring them all, this is the future of potions!

Dumbledore: Moon Scarlett, what is the secret of you...

A person from earth is reincarnated in the Harry Potter World as Draco Malfoy. Armed with future knowledge, he tries to defeat all obstacles while protecting his family, fighting Voldemort and figuring out how to deal with teenage girls.

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...

Harry's diary:

On 1991/6/23, I traveled to another world and was adopted by a couple. They were both very gentle, much better than my aunt's family!

On July 31, 1991, I returned to my original world and received a mysterious email. Oh my God, it was a magic school!

1991/8/8 I saved the world's richest man, Tony Stark!

On 9/9/1991, I encountered a mysterious man. He seemed... very weak?

1991/10/10 I was accepted as a disciple by the Supreme Sorcerer. Relying on the magic power in my body, I don’t need to pay the price like others!

1991/11/11 I became the greatest wizard ever!

...

Many years later, the Supreme Sorcerer, the Master of Chaos, the Third Dark Lord, and the Most Powerful Wizard in History, Harry Potter, faced the crazy reporters and said calmly: "

Thanos may be very weak, but he is right about one thing, the world needs a new order!"

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!"

After traveling to the Harry Potter world, Vaughn awakened the reputation system. As long as his reputation can be widely spread, he can gain reputation points to add points to the magic he has learned and upgrade it. There are also various tasks that reward magic power and even talents. So... the traveler keeps a low profile and pretends to be a pig to eat the tiger? Follow the plot and become a male mother for the iron triangle? Not possible! Hogwarts, the legendary white devil Dumbledore, the fateful entanglement between Harry and Voldemort... These are the best reputation machines. How can you get rich without stirring up trouble and destroying the plot? Harry: "Vaughn should be the savior. He stopped Voldemort from taking the Philosopher's Stone." Lupin: "Wolfsbane Potion, Werewolf Affairs Committee... Damn, it's a heart-pounding feeling!" Cornelius Fudge: "I want to rule the werewolves, I want to recruit Vaughn Weasley... Damn Dumbledore treats him like his own son, no, he protects him like his own father!" Dumbledore: "Vaughn is a magical genius, but what is more dangerous is his thinking. He always reminds me of someone. I must guide him well..." Vaughn spread his hands: "Don't get excited, resisting Voldemort, recruiting werewolves, challenging the Statute of Secrecy and starting a wizard revolution... I just want to gain some fame!"

The following is a real interview record:

"Professor Evans Kahn, what do you think of the rumors that you are the first generation Dark Lord and the confidant secretly cultivated by Headmaster Dumbledore?"

"That is pure slander!"

Evans stood at the Wizengamot's inauguration ceremony, his face indignant.

"Dark Lord? White Lord? These all sound too scary."

"If there must be a title, I actually prefer the word Beast King."

The next day, newspapers throughout the wizarding world published reports about the third generation Dark Lord changing his nickname.

"Wait, when did I admit that I was the Dark Lord?"

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