Having been transported to the world of Harry Potter, the boy, who initially only wanted to survive until his death, successfully defeated Voldemort. However, upon leaving Hogwarts, he discovered that the infamous Voldemort was merely a minor boss.

A product of forbidden magic, heir to the Black and White Lords. A powerful body forged from three bloodlines, a brand new soul transcending time. The magical world is in turmoil, as two generations of Dark Lords clash on the same stage, wondering who will reign supreme.

Dumbledore said, "I am your father."

Grindelwald said, "Bullshit, he's obviously closer to me."

Voldemort said, "You are the boss, I accept your position and I won't fight you anymore."

Everything is in Hogwarts: The Forbidden Son of the Black and White Demon King.

[Slytherin + Grindelwald template + contrast + righteous White Devil + introduction insufficient, please read the main text]

Jacks never expected that the template he awakened would be full of question marks.

[Current template: ??? (30% integrated)]

Only black magic was displayed at the SSS level!

Is this to make him the Dark Lord?

And... what the heck is this orientation correction protection?

Wait, it seems like Jacks has figured something out?

This is just... the Grindelwald template!

...

Many years later.

Born in Slytherin and modeled after Grindelwald, Jax was widely regarded as the new generation of dark magic!

But.

The truth is often the opposite.

Jacks: Please, I'm perfectly honest!

"Hey, how did I become a master of magic thief?"

"Professor Dumbledore, how did your Galleons get into my pocket?"

"Professor Snape, I swear, I have nothing to do with your lost warehouse of potions!"

Crait Frey is reborn as a legendary master of magic thieves, but he carries a vicious curse on him. However, this cannot stop the rise of a new star in the wizarding world.

From now on, please ask wizards in the magical world to call him, an outstanding faculty member of Hogwarts, a well-known best-selling author, a legendary explorer, and a recipient of the Order of Merlin...

Laudgreen displayed his extraordinary magical talent as soon as he entered Hogwarts.

Potions is easy to learn, but most of the finished products can only be drunk by animals. Snape regarded him as a fool who tarnished the great potions.

Transfiguration can easily turn inanimate objects into living things with their own thoughts, but it is powerless to do the opposite, which greatly puzzled Dumbledore.

In the study of spells, the spells cast by Lord always have some strange effects.

He only had no problems with Potions and Magical Creatures, and the magical creatures even regarded him as a child of nature.

Everyone praised him, saying he would become the next Newt Scamander, but he stuck to his profession.

Laudgreen: Although I am a master of Transfiguration, my spells are incredibly creative, and the magical creatures trust me, I am actually a botanist.

Garlon is reborn in late twentieth-century England.

It was only after receiving the Hogwarts acceptance letter at the age of eleven that he realized he had traveled to the world of Harry Potter.

Fortunately, he awakened his incredible talent of understanding that hard work pays off and that one percent of effort will be rewarded.

"Read the Standard Spellbook, gain 100% of your reward, and comprehend basic elemental witchcraft!"

"Read 'A Thousand Magical Herbs and Fungi', gain 100% of your reward, and learn advanced potion formulas!"

......

Create elemental witchcraft system, create alchemy system, create transformation system...

Created the art of time and space spiritualism, created the art of devouring world stars, created the Holy Tower of the True Spirit...

Harry Potter: After meeting the Great Wizard of Truth, I am no longer afraid of Voldemort!

Professor Snape: Can anyone lend me some magic stones? I haven't built my wizard tower yet!

As Garlon becomes more powerful, he creates complete wizard systems one by one, and the era of Hogwarts's conquest of the world has arrived...

[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!

"Hufflepuff + the main character of the story does not involve a love line + no CP + daily life + invincible"

My name is Adonis Anderson, and I’m a time traveler. In my previous life, I worked as a slave all my life.

All the inheritance that I can't spend in this lifetime is what I deserve.

But I didn't expect that this world is full of two faces, and there is another side hidden behind the scenes that cannot be revealed.

It was not until I received the Hogwarts acceptance letter that I realized that I was transported to the England of this time not to give me shares in some Fortune 100 company, but to dig a big hole for me.

Fortunately, I have the golden finger to help me work hard. Even if there is a socket spirit blocking the way, it still can't stop me from being lazy and lying down.

So I chose to join Hufflepuff, hoping to get through the seven years of school. If the Socket Spirit doesn't know what's good for me, then I don't mind letting him see what it means to be a screwed person.

But I didn't expect to meet Fred Weasley on the first day of school, and become roommates with Cedric Diggory at night. What does this mean? !

Am I assigned to the death group?

No! I don’t want to die! My parents left me so much money, and I haven’t spent it all yet, how can I die! !

Golden Finger, get up and move! ! !

Until one day...
