Harry Potter:

In 1991, Harry Potter, who was looking forward to campus life, stood on the platform of the Hogwarts Express, accompanied by his parents, godfather, Uncle Remus and a snow-white owl, and hugged and said goodbye to them one by one. The wind blew his bangs aside, revealing his smooth forehead above his green almond-shaped eyes. He just felt that he was the happiest little wizard in the world. The last person to say goodbye to him was his godfather, Sirius Black. "Harry, remember, have fun!" Black squatted down, his grey eyes sparkling, "If anything happens, you know, just look for Uncle Regulus—" This is a story about a game geek who plays "Assassin's Creed" and travels through time to the story of Regulus Black, a relative of Harry Potter. Regulus is responsible for hard work, and others are responsible for happiness! Protagonist: All..

[The unknown diary of a white devil]

"In 1991, I entered school, and together with the savior Harry Potter, the magic world gave me a good feeling. Magic is really wonderful.

"In 1992, I was a little bored today, so I just went out and killed a few Death Eaters for fun."

"In 1993, Dumbledore is really old and confused. How can people feel at ease if he doesn't hold power in his own hands? No wonder he is always disgusted by the people in the Ministry of Magic."

"In 1994, why is Voldemort so timid? He has been resurrected for a long time but there is no movement. Is he still the dark devil who doesn't take all wizards seriously?"

"In 1995, why did Grindelwald come out? Two generations of dark devils joined forces? Do you still have shame?"

"In 1996, he finally stopped hiding? Just right, solved it all at once. ”

......

Hermione: Harry! You must tell Dumbledore about this - well, you can tell Damon too.

Harry: Damon, thank you, you are the only one who always believes in me - what? You want to take a photo of me in women's clothing and send it to Snape - but - why?

Professor McGonagall: It is a loss for the entire British wizarding world that you don't participate in Quidditch!

Dumbledore: Damon, I think you are right, I made a mistake - I forgot the feelings of young people - but fortunately you are here, it seems that I can be a teacher with peace of mind, after all, this is the best for me.

Death Eater: Do you think Damon White has become more and more cruel recently? I really regret being infected with the Dark Mark...

[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...

If Dumbledore had not defeated Grindelwald.

If the war between wizards and Muggles really broke out.

If the finger witch that the faded one failed to meet was reborn in the body of an 11-year-old wizard girl.

My name is Hermione Granger, and I will rebuild the magic circle of this broken world.

(Contains secondary settings, rational discussion)

Many years later, Rita Skeeter, who had become the editor-in-chief of the Daily Prophet, asked: "When you decided to study at Hogwarts, did you foresee that you would be successful at Hogwarts?"

Mr. Andy Hall, then Minister of Magic, President of the International Confederation of Wizards, Chief Wizard of the Wizengamot, and holder of the Order of Merlin, First Class, replied helplessly: "?"

"At the time I didn't know a single spell, and I didn't even know I was a wizard."

Rita Skeeter: "So how did you learn magic?"

Andy: "You guys didn't [beep]?"

In 2026, Blue Planet was attacked by monsters from another world. Lin En, who was originally middle-aged, was forced to join the ranks of defending his country. Unfortunately, he was killed in an orc raid. When he woke up, he came to England 20 years ago. Reborn as Andres Mori with a complete set of golden fingers, he had a chance to save Blue Planet. Until many years later, he not only saved mankind but also led mankind to conquer the other world. He was called by humans: Marquis of Paradise Island, founder of Hogwarts, guardian of mankind, conqueror of the other world, and great magician.

(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.)

The setting respects the original work, with appropriate inferences and expansions, no CP breakup, no female lead, no system, no lowering of intelligence, and not a cool article; a daily growth article that studies magic! (If you think daily writing is watery, if you think studying magic is boring, or if you want to read pretentious and face-slapping writing, then don’t waste your time!) An oriental boy was abandoned in a British orphanage in the 1980s and 1990s, but he was not depressed, because the soul inside him was an adult from the Blue Planet. He knew that he was special, not only because of his identity as a time traveler, but also because of his super powers.
