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...

The incomplete fragment of the artifact carried a soul to the magical world we imagine, albeit a little too early. Voldemort was still Tom Riddle, Snape's mother hadn't been born yet, and the original Dark Lord was still striving for the greater good.

The male protagonist has no CP in the main text, but there is ambiguity in the early stage. Support ggad, Sili

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.

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.

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.

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!"

Burning souls, casting forbidden spells. "Black Emperor" Klein Grindelwald successfully traveled through time and started his third life. This time, he wants to shut up all doubts and prejudices and ascend to the highest Mithril Throne in the magic world in another way! "Knowledge is the eternal pursuit, and power is just a by-product in the process of seeking truth." "Magic is neither good nor bad, neither black nor white.

Karen, who thought he had traveled to a parallel world, finally found out that he had come to the world of Harry Potter when he was eleven years old.

With eyes that can see through magic, Karen is destined to become a master of the magic world.

Karen has always felt that the most fascinating part of magic is not those earth-shattering spells, but the subtle flow of magic in daily life.

He would rather spend his time reading various magic books in the library or observing the magic background of this thousand-year-old castle.

On a frozen tundra, through the billowing steam and blinding blizzard, the shape of a colossal beast slowly emerges.

A grotesque construct seemingly cobbled together from wood and iron, devoid of any sense of beauty or design. Whether it can even move is a mystery—it’s a wonder it holds together at all.

At the front is a massive steel face locked in a twisted grin, with a red mechanical tongue lurking inside its maw.

Below, four claw-like mechanical legs—thin and bird-like—stride awkwardly through the snow, barely supporting the towering monstrosity above. Their fragility is alarming against the beast’s massive frame.

They say, deep within the fortress, a mysterious figure dwells… weaving the fate of all who live.

Xiao Er transmigrates into the world of Harry Potter and inherits the Black family estate. Upon entering Hogwarts, he discovers that this magical world is far from simple — and his own origins are even more mysterious.

He dominates Slytherin, becomes the top student, handles Snape with ease, teases Draco, redeems Theodore, reunites GGAD (Grindelwald and Dumbledore) at the tower, establishes a magical throne, inherits the ideals of pure-blood supremacy, and breaks through a decaying world!

One legendary tale after another unfolds.

— Content Warnings —

The protagonist starts off as someone who goes from rags to riches and might get a bit arrogant, but evolves into timeless elegance.

Apart from GGAD as the canon male/male pairing, there’s no romance in the main plot. Fan extras might include other CPs (couples).

Ron is portrayed as mildly antagonistic in the early stages, but he matures later on.
