[OC warning + many personal settings + no female lead]

Since arriving in this magical world, Bai Yang has had only one goal.

That is to graduate from Hogwarts safely.

So, anyone who prevents him from graduating should just die!

The magical barrier shattered under the spell of the cursed spirits! Dumbledore pointed his wand at the white-haired man emerging from the crack: "Are you friend or foe?" Gojo Satoru removed his eyepatch: "Here to rescue people—and incidentally, to have a cross-world brawl."

William, an ordinary person, originally thought he would live a plain and uneventful life.

A letter delivered by an owl transported him to a magical world.

Is the protagonist in danger?

William said he didn't have time.

Has Hermione become cunning?

Hmm, and then what?

Dementor Riot?

Now we have the materials!

William never considered himself a freak scientist.

He was just an ordinary, unremarkable scholar.

[HP Fanfiction + Imaginative Stories + Lighthearted + Humor] Li Mu, who transmigrated into the Harry Potter world, didn't gain extraordinary magical talent or a prestigious family legacy. Instead, he went from a handsome 1.83-meter-tall young man to Harry Potter's chubby cousin. Before he could even calm down from his impulsive act of banging his head against a wall, the system issued him his first mission: eat the revolver in front of him, then kill the dark wizard who was about to arrive in Little Wheegham, Surrey.

Having transmigrated into the last bloodline of the Grindelwald family, he initially wanted to live a low-key life, but was forced to bind himself to the "Underworld God System".

From then on, the style of Hogwarts completely went astray.

"Petrify everyone? That's too lame. Come and witness the power of our Zaun petrification!"

"Want to learn the Patronus Charm? First, pay protection money to the system. Avada Kedavra can turn a melon into a rainbow color for you."

Dumbledore looked at the savior, who had been turned into a "henchman," and fell into deep thought: "This kid...maybe he can form the most cowardly villain alliance in history with Tom?"

Until one day, I was cornered by the Dark Lord, and the system suddenly prompted me—"Hey buddy, there's only one guy on the other side, call for reinforcements to take him down!"

From the moment Yang Tian was born, he knew he was born into a wizarding family that combined Eastern and Western traditions. It seemed his life was settled; his parents loved him, everything went smoothly, and he lived a life that was both awkward and comfortable.

Unexpectedly, the mysterious and powerful evil organization turned out to be the family's mortal enemy.

Clash after clash, battle after battle...

Yang Tian and Nightmare both moved forward with determination!

But what's with Dumbledore and Snape's wariness and estrangement?

What's with the supposed break in the transmission of magic between the East and the West?

Why is Salok so ubiquitous?

But none of that matters! The support of my family, the help of my friends, the guidance of my teachers...

I will surely be able to fuse Eastern and Western magic, unravel the mysteries of ancient magic, and forge a brand new path!

Snape: This kid has unparalleled talent in potions, but he always substitutes precious herbs with cheap ones that I don't recognize. He's a total swindler!

Dumbledore: Is this kid still using Patronus? Those solid figures, could they be the legendary mythical beasts?

Voldemort: Kid, if you're so tough, don't use those two little pieces of paper, let's have a proper fight!

......

At the top of the world, he and his comrades stood tall.

Forward? Or...backward?

"Knowledge is our best friend, nourishing the growth of wisdom; curiosity is our best mentor, illuminating the horizons of exploration!" "Classmates! As long as we have this potion in my hand, Voldemort has nothing to fear. Times have changed, Voldemort!" Rhodes, the leader of Ravenclaw, delivered a passionate speech, crimson potion in hand. Albus Dumbledore looked at Snape in confusion: "Is this the soldier you brought with you? Will the potion in his hand blow up the school?" Snape said expressionlessly: "Probably not." ...In 20xx, Albus Dumbledore searched Rhodes' dormitory, stunned by the bottles of potion. "This is what you said you wouldn't do!" Albus Dumbledore looked at Snape angrily.

As long as you are willing to pay, you can destroy Malfoy, Black, and Lestrange.

As long as the money is paid, even Dumbledore can kill him.

Since then, the reputation of a "money-making madman" has quietly risen in Hogwarts.

Mysterious man: "I heard you are very powerful in magic, kill someone for me."

Hall: "One hundred Galleons."

Mysterious Man: "Here... help me kill Voldemort."

Hall: "Who?"

Mysterious man: "Are you scared?"

Hall: "You have misunderstood. That is the last bloodline of Slytherin, the great leader of the Death Eaters, the legendary Dark Lord, and the undead with seven clones!"

"This money is not enough..."
