Traveling through the world of Harry Potter, Wayne awakened the Chaos Lord system. As long as he created chaos and violated school rules, he would be rewarded.

Thus, Hogwarts ushered in the most lively period.

Dumbledore: "A student life that does not violate school rules is incomplete, but Wayne... please restrain yourself."

McGonagall: "I thought the Weasley twins were invincible, but I didn't expect Wayne to be braver than them!"

Professor Sprout: "Since he came, the badger has become a flat-headed brother."

Snape: "Azkaban! He should be assigned to Azkaban!"

Voldemort: "Don't bother with the Son of Prophecy, I just want to kill Wayne Lawrence! Now, immediately, right away!"

Wayne spread his hands helplessly: "I'm just a little more lively, why do you keep urging me to graduate?"

The story begins. Ian thought he was just a little wizard with a bit of talent and a simple [plug-in]—as long as he worked hard, he could become stronger.

However, as time passed, he began to realize something.

The teachers guiding him in magic were either legendary powerhouses or figures straight out of myths.

*"Standing before you is the noble Apostle of the Maze, the Co-Spokesman of the Old Dead, and the heir personally chosen by the founder of Hogwarts!"*

What? The noseless monster wants to make a move?

He must have never heard of the original spell recorded on my Chocolate Frog’s Famous Wizards Collection Card!

Dumbledore: *"That spell…!"*

Dumbledore’s expression changed as Ian recited *"Call of the Guardian Spirit."*

Silver-white threads surged, intertwining and condensing until a familiar figure appeared, one that a certain professor had spent his entire life drowning in guilt over.

Adrian Wisen, who traveled to the world of Harry Potter, didn't have any big ambitions. As a professor at Hogwarts, his daily routine is to take care of children, farm, and cause trouble for the elderly headmaster. Everyone who knew Adrian Wisen also knew that he was a kind and amiable wizard. Oh, there is one important thing. Never go near those plants he grows!

Times Square in 2024 was bustling with activity. Oliver, holding Hermione's hand tightly, weaved through the throng. All around, advertising screens flashed, and street performers captivated passersby.

Suddenly, Hermione stopped dead in her tracks, her gaze riveted by a giant screen. Oliver followed her gaze and saw footage from Harry Potter and the Sorcerer's Stone. A familiar scene emerged: Harry's first time entering Hogwarts, the mysterious and majestic castle, and the fantastical opening ceremony.

"Oliver, look!" Hermione's eyes sparkled with excitement, and her voice rose unconsciously, "That's our world!"

Oliver smiled and squeezed her hand gently, "Yeah, I didn't expect to see it here." His thoughts drifted back to his time at Hogwarts, the days of flying on broomsticks, the novelty of learning magic spells in class, and the thrill of adventure with his friends.

People around also noticed the screen. Some stopped to watch, and occasionally a few comments could be heard.

"This movie is a classic, I love it so much." A young man exclaimed.

"That little boy must be Harry Potter. It feels so magical." A little girl held her mother's hand and stared at the screen without blinking.

Hermione listened intently, her face beaming with pride, as if she was showing Oliver her most treasured treasure.

"I really want to go back and take a look," Hermione said softly, her eyes full of nostalgia.

In the year 1340 of the Shire Reckoning, one year before the departure of the Lonely Mountain expedition, the Grey Wizard had yet to visit the Shire, the Dwarf King was still forging weapons in the Blue Mountains, and the dragon still slept deep within the mountain…

In that very year, a young wizard unexpectedly crossed into Middle-earth, carrying the Hogwarts Sign-in System.

Overnight, Hogwarts Castle rose from the ground, standing tall and majestic on the lands of Middle-earth; flying broomsticks streaked across the skies, becoming a unique sight in this world.

In the wild lands, the legend of a black-robed wizard began to spread silently.

He was a friend of the Elves, a bane to the Orcs, a nightmare to the Trolls, and the lifelong nemesis of the Dark Lord Sauron.

Years later, when the Dark Lord was defeated, the Elves sailed West, and the Age of Men began—Duir, who had signed in at all corners of Middle-earth, looked toward the fabled lands in the West.

Qi Komo unexpectedly transmigrated to the world of Harry Potter and gained a "Game of Life System." This system allowed him to enter game worlds and, by achieving in-game accomplishments, gain "materialization chances" to bring items from the games into reality.

He loved playing games, but before he could even celebrate, he discovered that the games he encountered were all frustrating ones like Elden Ring.

Fortunately, as a member of the "Wind Spirit Moon Shadow Sect," he had the sect's protection. Whenever he faced a difficult game, he could always find a way to lower the game's difficulty.

And so, Qi Komo lived a carefree life in the Harry Potter world, attending school, playing games, and raising little witches.

Many years later, looking at Hermione, now the Minister of Magic who had defeated both the Dark and White Lords, Qi Komo was filled with emotion.

"Raising" games are indeed the most fun.
