"Extraordinary wisdom is mankind's greatest wealth. I came to Hogwarts to learn the wisdom accumulated over the years," said Blackley.

What kind of story will unfold when a new friend enters the Harry Potter story?

Dumbledore: "Oh, that little Ravenclaw kid you're talking about. He's a smart kid who's obsessed with knowledge."

Harry: "Blackley is a very reliable man, but he can be strangely persistent sometimes."

Hermione: "Merlin's lace stockings! This is the first time I've seen someone so eager to learn."

Blackley: "Knowledge is the most precious treasure in the world, and I am a goblin with an extreme greed for knowledge. So, Professor Dumbledore, can you really not explain the principle of the Killing Curse? I want to invent a counter-spell for the Killing Curse."

Dumbledore: “…”

Voldemort: "That little wizard is simply a lunatic. He actually wanted to capture me and dissect me for research! He is a lunatic!!!"

This book has many private settings. The protagonist is an orphan in this world. His adoptive father is a super ancient magician and alchemist who has lived for 17,000 years. He knows a lot of ancient magic and ancient alchemy and will teach the protagonist some, but he rarely appears and basically appears to complete the protagonist's character.

Well, this is a legendary wizard from another world. At the critical moment of entering the divine realm, he was inexplicably drawn into the world of Harry Potter by a space-time wormhole. Faced with...

[Cyberpunk][Harry Potter][Dual World Shuttle]

Harry Potter: Old man, the work is done, give me the money

Dumbledore: Harry, 60 points from Gryffindor for your bravery.

Harry Potter: Damn it, I almost died there, and you just give me some extra points and that’s it?

Dumbledore: ...

Malfoy: Pott, you shouldn't be hanging out with those mudbloods, the disgrace to purebloods.

Harry Potter: Go away, company dog, oh no, puppy

Priest: Harry, I have a big order that I think you can take on.

Harry Potter: Dad, don’t you always ask me to handle your big orders internally?╮(￣⊿￣)╭

V: Harry, you, want to go to Arasaka Tower with me and cause a scene?

Harry: You hit the nail on the head. Let the year 2023 bring back the past, V. Let's burn Arasaka Tower to ashes!

Mann: Harry, how are you? (He leans forward) Um, that soothing agent you have...

Harry: It's the soul... Never mind, I'll give you a 30% discount for Rebecca's sake.

Rebecca: Harry, explain why you stood me up last time, honey~ (pulling out the iron gall)

Harry: I, um, I said I traveled through time, do you believe it... Don't load the gun!

Left at his aunt's doorstep, baby Harry Potter arrived in Night City after a mishap. Raised by Father Sebastian, he became a "special" mercenary for the Valentino Gang. But after a mission, he traveled back to his original world, and a line of small words appeared on his prosthetic eye: Shuttle Energy, Accumulating...

(No heroine + tearing umbrella in the rain + original god card + funny and relaxed)

The protagonist begins by fusing the soul of the Grim Reaper and directly robs Dumbledore's Philosopher's Stone! Becoming the Demon King of Hogwarts.

He joined the Nazarene Church, became a professor, trained Draco and Harry, and became Theodore's father.

Create an army of undead and treat Voldemort's remaining soul as a crunchy snack gift pack.

Occasionally, I would get furious with Dumbledore and Grindelwald, and this comfortable life was simply wonderful.

Kerry Black is a time traveler. She doesn't have any cheat codes, but she possesses an innate ability to sense and relate to creatures. Her dream is to capture and train all manner of magical creatures. Her goal is to use them to defeat Voldemort, and then live a carefree life. She can't write an introduction; writing is a hobby, practice, and not a livelihood.

A necromancer with the title of natural disaster, because of an accident, he traveled to the world of Harry Potter.

His name is Ian, and he was an orphan in the first life, and only the stories of Harry Potter accompanied him in his childhood.

In the second life, he is a necromancer that everyone fears.

When he comes to Hogwarts, where will the fate of this world go…

After many years:

Voldemort: Me? Dark Lord? Don’t talk nonsense! Be careful, I will sue you for spreading rumors!

Dumbledore: Ian is the patron saint of the wizarding world!

Grindelwald: It was Ian who made the wizard great again!

What? You're saying I'm the prophesied savior of the wizarding world? Are you sure? How about you take a look at my Ten Thousand Souls Banner before you speak? The story of an Eastern magic cultivator attending Hogwarts.

Travel through the ruined magic academy, the epic battlefield of blood and fire, and the doomsday scorched earth where demons wreak havoc.

When Zhang Peiran opened his eyes in the cycle of death, the bricks and stones of Hogwarts Castle were being corroded by the Dark Mark, the smoke of war in Middle-earth obscured the brilliance of the Silmarils, and the Eye of Sargeras could be seen on the broken coastline of Azeroth.

Voldemort's power was infused tenfold by the abyss. The Mordor orc army, accompanied by the fallen Maia, swept across the earth, and the Burning Legion's twisted fel warships obscured the entire starry sky.

There is no way to retreat, only hands holding the magic wand and rune sword, walking alone in every world where eternal night is approaching.

(Advance warning: This is a long and endless story with no female protagonist. It focuses on the magic system. The current planned routes are "Harry Potter World", "Lord of the Rings Middle-earth", and "Azeroth World of Warcraft".)
