Waking up, Joel found himself transmigrated into the magical world of Harry Potter, bringing with him a "Pipi Shrimp" pay-to-win system.

Charms, Transfiguration, Potions...

Spend money + grind = boundless magic!

But slowly, Joel discovered that this system was as mischievous as its name suggested.

"I absolutely cannot do something like that!" Joel vehemently refused a system-issued task.

One morning, Professor McGonagall's office doorknob mysteriously vanished.

The Gryffindor lioness was furious, while Joel, tucked in a corner, contentedly watched his Transfiguration progress bar tick up on the system panel.

This is a story about a protagonist making money and causing mischief at Hogwarts.

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!

This book and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.

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?"

"Don't put all your hopes in the 'savior', let me carry the burden!" "Believe me, there is nothing to fear from Voldemort, he was never our true enemy!" Ethan Vincent, winner of the 2008 World War II Award

van, who traveled through time and space and became a descendant of Merlin: Do you know how many secrets there are in the magic world? Why can ancient runes be engraved on magic wands? Why can it enhance magic power? What is its connection with modern magic runes? Is the boundary between life and death behind the curtain of the Department of Mysteries of the Ministry of Magic? Is there a secret left in its time hall that can turn back time with a time converter? Why does prophecy magic need to contact celestial bodies, why can Merlin understand the language of all animals, and why is the magic of love so powerful? Knowledge is infinite, but my life is limited! I will never allow anyone to prevent me from exploring secrets! I'm talking about you, the noseless monster! You are a mediocre person who only knows soul magic and black magic! This book is also known as: "Hogwarts: Merlin? Why do you call me ancestor?" "Hogwarts: Voldemort? He knows nothing...

In the year 1340 of the Shire Reckoning, one year before the departure of the Lonely Mountain expedition, the Grey Wizard had yet to visit the Shire, the Dwarf King was still forging weapons in the Blue Mountains, and the dragon still slept deep within the mountain…

In that very year, a young wizard unexpectedly crossed into Middle-earth, carrying the Hogwarts Sign-in System.

Overnight, Hogwarts Castle rose from the ground, standing tall and majestic on the lands of Middle-earth; flying broomsticks streaked across the skies, becoming a unique sight in this world.

In the wild lands, the legend of a black-robed wizard began to spread silently.

He was a friend of the Elves, a bane to the Orcs, a nightmare to the Trolls, and the lifelong nemesis of the Dark Lord Sauron.

Years later, when the Dark Lord was defeated, the Elves sailed West, and the Age of Men began—Duir, who had signed in at all corners of Middle-earth, looked toward the fabled lands in the West.

[Location: Aman. Would you like to sign in?]

I am a great alchemist and the supreme wizard king in the magic world.

Loki regards me as a nightmare, Thanos regards me as a thorn in his side, Thor... Why do you call me brother-in-law?

You can call me by my name, John Wick.

My motto is: "There is nothing that cannot be solved by your weapon. If there is, add an Avada Kedavra." ...

Ciel traveled through the magic world and became a distant relative of Professor Sprout. He was also tied to the planting system - planting plants can get rewards.

"Plant ten Devil's Snares and get 10 fragments of Binding Curse Enlightenment. Your Binding Curse has been upgraded to the legendary level."

"Plant ten Biting Cabbages and get 10 fragments of Sharp Spell Enlightenment. Your Sharp Spell's killing power has been greatly improved."

So Hogwarts has a diligent and thoughtful little wizard who is dedicated to planting trees.

Three-headed dog? Philosopher's Stone? Nothing to do with me.

Basilisk? The heir of Slytherin? Stay out of it.

Triwizard Tournament? Cedric died? That's a pity, plant a tree to commemorate him.

"What? You said the Death Eaters dug up my vegetable patch and trampled my saplings?"

...

[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...

What should I do if [Transformation] + [Marvel] + [HP]

is in the wrong world?

Hermione dressed as an HP world, but appeared in Marvel.

A mysterious magic book that makes Hermione jump back and forth in the worlds of Marvel and Harry Potter.

……

Tony Stark: It's time to study the Anti-Wizard Warframe.

Hermione: Are you talking about your ragged mantling that was torn down by whom?

Hulk: Roar!!

Hermione: Shut up and be careful I remove your pants...... Except for your weapons!

Ancient One: There are no mages on the timeline......

Hermione: Again, I'm a wizard!

Nick Fury: Where exactly are you from?

Hermione raised an eyebrow: I, Hermione, from Hogwarts!
