Maurice, reborn, wanted a peaceful life, but a letter from Hogwarts disrupted his plans. Along with it appeared a book detailing various forms of necromancy. Becoming a necromancer? Perhaps that wasn't so bad. Bones as servants, ghosts as companions, the whispers of the dead murmuring in his ear. "I'm just an ordinary wizard who loves research," Maurice said with a gentle smile to his trembling classmates. Until one day, he suddenly woke up in front of the mirror—wait, could he be a psychopath who deals with corpses all day?

Travel back in time to Harry Potter, and acquire magical skills by spending gold!

From then on, the art style of the magical world completely went astray.

Only I know that I just want to make more money, and incidentally... become a god.

Years later, Voldemort, wielding the Elder Wand, roared at me, "How dare you oppose the Dark Lord!"

I sighed, and behind me slowly appeared a skill tree, illuminated in gold and stretching across the sky.

“Sorry, Mr. Tang,” I snapped my fingers, “but you’re preventing me from making money.”

(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..."

Upon entering Hogwarts, Andre discovered that his spells possessed their own independent thought. When practicing the Glowing Charm, it disapproved of Andre's weak magic, roaring, "At the end of the path to immortality, who reigns supreme? A glimpse of glowing light, and all is vanity!"—That very night, a divine light pierced the Forbidden Forest, alarming the entire Ministry of Magic. When practicing the Ironclad Charm, it scorned Andre's poor defense, working through the night to comprehend, "Crimson Spear, Immortal Shield, slaying all Celestial Kings and annihilating the Nine Heavens!"—The next day, Voldemort's Killing Curse struck it, leaving not even a mark. Andre trembled, staring at his wand still frantically chanting "Involution, Cultivation, and the Evolution of the Imperial Scripture." "Headmaster, before I learn Avada Kedavra, is it too late to expel me?" "That thing says it's going to sacrifice the entire wizarding world for its ascension!"

Leonard, an earthling, travels to Hogwarts and awakens the powers of the Seven Gods of Teyvat (wind/rock/thunder/grass/water/fire/ice), but he needs to gradually unlock them through the sacred relics of Hogwarts' underground leylines - the statue of the God of Wind in the Astronomy Tower, the statue of the King of Rock in the Chamber of Secrets, the Fountain of Wisdom in the Forbidden Forest... Each sacred relic contains a thousand-year contract between the ancient elemental wizards and Hogwarts.

As Hermione Granger's distant cousin, his wandless levitation and rock-lance combat astonished the wizarding world. Hermione, with her photographic memory, translated these powers into learnable "elemental spells," becoming his sole theoretical partner. From using wind to generate bay leaves in Potions class, to using a rock shield to block the basilisk's petrifying gaze in the Chamber of Secrets, to using lightning to split the Dementor's black mist in Azkaban, the two redefine the possibilities of magic through the complementary "wisdom and power" of the original novels.

As the power of the Seven Gods is gradually released, Leonard discovers that Voldemort's Horcrux is actually a "crystallization of abyssal energy", which can only be destroyed by the corresponding power of God's Eye - the Rock King's Spear shatters the golden cup, Wuxiang cuts off the diary with a single blow, and the Echo of Green purifies the poisonous fog... and Hermione pieces together a bigger truth from the family genealogy and "A History of Magic": the gargoyles and leyline obelisks of Hogwarts, and even the entire magical world, are all in line with the elemental laws of Teyvat.

When the final battle came, the shadows of the Seven Gods appeared over Hogwarts. The Wind God swept away the Death Eaters, the Rock God held up the city shield, and the Thunder God cut off the dark magic... Leonard and Hermione stood in the center of the seven-pointed star, weaving the fate of the two worlds with the resonance of elements - it turned out that as early as a thousand years ago, the authority of the Seven Gods had laid the foundation for the protection of the world.
