[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!

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. The same applies to second-years; Professor Trelawney, who is in charge of Divination, senses that her fortune is not good this month and she is not suitable to teach. 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!!!!!!!!!...

Gringotts's finest anti-charm specialist, the archaeologist of the wizarding world, Hogwarts' professor of ancient magic, a destroyer of pure-blood supremacy, and Severus Snape's nemesis—

Toby Heimer.

Eleven-year-old Arthur, an ordinary boy, decides to earn money to pay for the expensive tuition of a good secondary school. Thus, *Harry Potter and the Philosopher's Stone* was born... Fudge, in the basement of Whitehall, London, clutches the Muggle children's novel in horror...

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."

Relaxation + delicious food + healing, the taste of magic.

Ye Tao, a recent graduate of New Oriental Chef Academy, shared delicious food with his friends in this magical world, exchanging stories and experiences. The Hogwarts farm became the focus of their conversation.

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"? Why did that gloomy, black-haired man with a bun stand up and applaud? Huh? What's that platinum-haired boy over there doing, pulling her along? Also known as "Hogwarts...

(No system + villainous protagonist + ensemble cast) (PS: Several million-word HP novels already exist, feel free to read) Kong En, Chinese. He entered Hogwarts in 1971 and, after graduating from Slytherin, joined the Ministry of Magic as an outstanding graduate. Using his memories, he helped Fudge become the thirty-second Minister for Magic, earning him a close confidant. To counterbalance Dumbledore, Fudge sent him to Hogwarts as a "Senior Investigator," while Kong En, seeking further advancement within the Ministry, chose to use extreme exam-oriented education methods to rapidly improve student grades, thus enhancing his own political standing. "Now, I will issue the Ministry of Magic's 'Education Order No. 23'!" "Hogwarts will be under closed, centralized management." "Boys will have buzz cuts, girls will have short, shoulder-length hair, uniform hairstyles, uniform clothing." "Timers will be installed in the toilets." "Male..."
