Roger traveled to the world of Harry Potter.

The game started on hellish difficulty; he became the apprentice of an old, powerful, and extremely temperamental dark wizard. Just as he was cautiously serving this unpredictable mentor, he unexpectedly discovered that the bio-computer he had developed in his previous life had also transmigrated with him!

From then on, Roger's magical training began with the three Unforgivable Curses! "Analysis of the Imperius Curse complete." "Begin observing Professor Quirrell."

Years later, when the Daily Prophet was preparing to write a legendary feature on Mr. Roger Lewis, prominent figures in the wizarding world spoke out:

Professor McGonagall (with a serious expression of amazement): "Without a doubt, Mr. Lewis is an unprecedentedly outstanding graduate in the history of Hogwarts." Dumbledore (his wisdom gleaming behind his half-moon spectacles): "I must admit that no one understood the nature of magic better than Roger. Not even the four founders of Hogwarts." Voldemort (in a complex tone): "It is well known that I made indelible contributions to Roger's magical research..."

Rita Skeeter (writing furiously with her quill pen, her eyes gleaming with gossip): "Mr. Riddle, was it the summer before Mr. Lewis enrolled?"

Voldemort (lost in memories): "Sigh...that summer, they invited me to participate in the experiment, though the method was crude...If they had said it was to develop an elixir of immortality, I could have provided tremendous assistance! I wouldn't have needed to go through the trouble of finding the Philosopher's Stone...I still deeply regret missing this opportunity to return sooner!"

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!"

HP+ The Sorcerer Supreme, single female lead Hermione, with a system

In 1991, while the new students at Hogwarts were struggling with the Levitation Charm, Silas Killer of Ravenclaw could already casually open portals. This seemingly "Muggle-born" new student had actually awakened as a time traveler at the age of seven, carrying a head full of knowledge from the original stories and a "system," and moved into the magical castle four years ahead of schedule.

He disliked the wand for restricting his nature, and instead conjured light shields and lightning bolts with his bare hands. While others dodged trolls, he countered with an Avada Kedavra, forcing Dumbledore to seek him out for a chat.

Silas, possessing dual magical abilities and an unparalleled talent for witty remarks, becomes the biggest plot hole in the Harry Potter world. His Hogwarts experience is a collision of tradition and subversion, a legendary journey for a "prospective Sorcerer Supreme."

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.

Dumbledore: "Give me a copy of The Quibbler! I feel like ants are crawling on me without a new episode of Dungeons & Dragons!"

Voldemort: "Summoning the Death Eaters can wait, but whoever keeps me from watching the new episode of The Lord of the Rings is waiting to eat the Avatar."

Malfoy: "Vos-lo-da! That's not right. Why can't my dragon roar repel it? Let me study The Quibbler again."

Harry Potter sent out his protest letter for the twenty-third time: "I solemnly protest against The Quibbler's invasion of my privacy. It must have cast a tracking spell on me. Otherwise, how could it know me better than I know myself?"

It all started when Andre traveled through time and space to become the adopted son of the Lovegood family and Luna's brother.

In order to save his family from bankruptcy and upgrade himself, Andre decided to become a great writer in the magic world.

Become a literary giant in the wizarding world, starting with serializing "Harry Potter"!

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.”

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!"

(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..."
