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!

As a graduate of the top-tier program at Wudaokou Technical College, Taowu, after successfully completing the Hogwarts Relics and mastering various ancient and dark magics, wreaked havoc in the wizarding world, she was struck by lightning and restarted. She was transported a century later to the Harry Potter era, carrying her post-record abilities. Determined to cultivate Bite Kale, she insisted on entering Hufflepuff. Taowu: You call yourself Voldemort? Voldemort: No, no, no, just call me Tom. (Including but not limited to Orminus, Newt, Harry, Draco, Cedric, Wood, the Weasley twins, Percy, Theodore, Blaise, Sirius Black, Regulus, Tom Riddle.)

Li Wei, a Chinese, entered Hogwarts in 1971 and graduated from Slytherin House. Twenty-one years after graduating from Hogwarts, he was accused of "spreading and proliferating the Dark Arts" and, after defeating nine Aurors sent by the British Ministry of Magic to arrest him, was personally summoned by Dumbledore and forced to become the new Defense Against the Dark Arts professor. "First-years, Professor Hooch, who is in charge of flying, told me that she is not feeling well today, so both flying classes this afternoon will be replaced with Defense Against the Dark Arts.

For the next month, you will not need to attend any Divination classes. Please remember this and make sure you don't go to the wrong classroom." "NO!!!!!!!!!...

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!"

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."

Feng Xingchen lived in China for 12 years. A magical uprising killed seven of her servants. To suppress her inner spiritual energy and magic, she was forced to teach at Hogwarts in England. Yes, as the eldest sister of the Tianheng Sect, she came to teach. But something seemed off. Why was that tattered hat constantly shouting "Slytherin"?
