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.

"How does it feel to be given the name Rozier?" "Get lost!" "How can you be so heartless!" "Stop with that gloating look. And can you please stop bullying those three little ones and Malfoy? You're practically ruining them!" "Tch, what do you know? You're having fun outside, while I can only find my fun at Hogwarts." These were the days these two shameless rascals spent having fun at Hogwarts.

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...

This is a story about hanging out at Hogwarts.

First Transfiguration Lesson

Loren: Look at that cat above, it looks so easy to touch.

Hermione: Heartbeat, in short, it is heartbeat.

five minutes later

Hermione: Loren! ! !

(PS: The three little ones are the same age, they don’t follow the main line of the original work, they don’t have a system, and they try their best not to be OOC.)

Will Evans wakes up to find himself transported to the world of Harry Potter. Good news: he knows the entire plot. Bad news: he knows nothing but the original story. So, Will decides—to cling to Dumbledore's coattails and achieve a life of effortless success! "Professor, Quirrell has a face on the back of his head!" "Professor, the diary has a mind of its own, burn it with Fiendfyre!" "Professor, don't wear that ring, it'll kill people!" Dumbledore: ...? When the greatest wizard holds the script, Voldemort's Horcruxes face their most disastrous failure in history. In their first year, they prematurely eliminate Peter Pettigrew. In their second year...

"You'd better find something to eat before dark." This was the first thing Kane heard after running away from the Dursleys. Okay, I knew I hadn't completely escaped the Famine world... but thankfully, his ability to manipulate his shadow in Famine still remained, not only saving him from starving to death after running away and being killed by invading shadow creatures at night, but also bringing him other benefits in this world. Wait... what does "for using dark magic in front of Muggles, now granted a VIP status in Azkaban" mean? Dumbledore blushed and quickly snatched the envelope from Kane's hand, replacing it with another. A Hogwarts acceptance letter, this time it's right.

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..."

Original title: "The Secret Black Cat of Hogwarts". The protagonist is not a saint, and the IQ of all the characters is basically online.

The Oriental Black Cat brought mysterious power into Hogwarts. There are so many ghosts in the school, I really want to eat one, the Dementors taste very good, Voldemort is the main meal, there is no escape!

Centaur: The end of the bear, the destroyer of herbs, the nemesis of the eight-eyed giant spider, the ominous darkness...The Mars tonight blinded my eyes.

Draco: He is a true aristocrat! What an elegance!

Simo: shepherd of lost lambs, ferryman of the sea of ​​soul, life mentor, pioneer of art.

Macon: I'm a regular little black cat.

Voldemort: Great! I am beginning to understand everything!

Harry Potter:

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!)

"When others travel through time, they see the system and the old man in their minds, but why is it that when I see it, it's just ice cream?"

When wizards in "Harry Potter" cast magic, emotions are of paramount importance, and can even be said to be the foundation of magic.

So, what kind of journey will a pure soul with a spirit of sacrifice in another world embark on when paired with ice cream that symbolizes happiness and joy?

Where will the pure-blooded nobility go? Will tragedy repeat itself? Will our victory still be a "lose-lose" victory?

When "Harry Potter" truly becomes a grand world, then are the enemies and crises really only hidden within us?

Following the aroma of ice cream, we headed to Hogwarts in 1991 to find out

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!"
