[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!

[Single female protagonist Hermione + mainly based on the movie plot, later plot changes + system]

Kevin traveled to the world of Harry Potter and grew up in an orphanage without ever coming into contact with magic. It was not until he was 11 years old that he finally received the admission letter to Hogwarts.

Reborn, he just wants to enjoy this magical journey, but as time goes by, he can't help but get caught up in it...

Snape: Kevin? Humph! Just a cocky brat with a bit of talent.

Dumbledore: Kevin is such a good boy who would go to great lengths to help his friends.

Voldemort: Kevin, this unethical and despicable villain! He has attacked me with a crowbar every time I die!

[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.

[Daily flow, easy, very talented in magic, from the same class as the Weasley brothers, single female protagonist (original), may be a little worse in the early stage, but will improve in the later stage, so please watch it later]

Learn magic here and live a peaceful life

But some vengeance still needs to be avenged.

"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.

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.

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!"
