Rowling travels through the world of Harry Potter and awakens to become a necromancer.

Having escaped Azkaban twice, he is famous (and infamous) in the wizarding world.

But he was hired by Hogwarts as a professor of Defense Against the Dark Arts.

Dumbledore: "Letting Rowling become a professor at Hogwarts is the best decision I have ever made in my life. But Rowling, why are you sitting in my seat?"

Snape: "You are definitely the next Dark Lord. I will keep an eye on you. Wait, why did you expel me?"

Professor McGonagall: "Rowling, I've told you many times that Transfiguration can't turn your pile of skeletons into a catgirl!"

...

Many years later.

Some people call Rowling the greatest wizard in the wizarding world after Dumbledore.

Some people also say that Rowling has influenced the atmosphere of the magical world and is a sinner of the magical world!

Some even say that Rowling becoming the headmaster of Hogwarts is a disgrace to Hogwarts!

Rowling, surrounded by the Scourge, sat on the golden chair in the Hogwarts Great Hall, looking helpless:

"How did I, a prisoner of Azkaban, get hired as a professor at Hogwarts and eventually become the headmaster?"

"It can only be said that a person's fate..."

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.

Kevin traveled to the world of Harry Potter and grew up in an orphanage without ever coming into contact with magic. It was not until he was 11 years old that he finally received the admission letter to Hogwarts.

Reborn, he just wants to enjoy this magical journey, but as time goes by, he can't help but get caught up in it...

Voldemort: Kevin, this unethical and despicable villain! He has attacked me with a crowbar every time I die!

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 life of a special wizard in that familiar yet strange world, in which we will become the protagonists.

(In memory of my infinite yearning for that magical world, in memory of the days when I used to read under the desk or in the bed!)

In the wizarding world, magic only erupts when one is about to turn eleven. Rhine was ready to lie down when he just received the Hogwarts admission letter, until...

[Congratulations to the host for joining the Chan Sect, the Honghuang human connection system is officially bound]

Rhine: "This is Harry Potter, system, are you crazy?"

Rhine fell silent as he looked at the half-blood giant Hagrid in front of him.

"Okay, this is the primitive world, right?"

"I just want to ask, are you authentic?"

My dear grandpa is actually a werewolf, the truth behind the Philosopher's Stone, and the back-up man behind the four founders.

None of this prevents Loren from being a bastard, having fun with Seamus, exchanging experiences with the twins, and explaining the weirdness of Quidditch...
