My name is Leggett Black.

After crossing over, I obtained a system....

It was also from this day that the world began to emit shrill screams.

Tang: Damn it, who stole my true energy!!!

Yu: "Ahhhhhhhhhhh!!! Oh my god!!!"

Jia Zhang: "Old Jia, please come back and take this thief away!!!"

In short, this is a story about exchanging everything in the Harry Potter world...

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.

"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

Many years later, Harry Potter, who was hailed as the greatest white wizard of this century after Dumbledore, was interviewed by a reporter.

"Mr. Potter, is the person you respect most Headmaster Dumbledore?"

Harry shook his head.

"Is that Professor Snape?"

Harry still shook his head and said softly, "From beginning to end, there is only one person I respect, and that is my teacher - Al Yaxley."

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"!

Harry Potter: Old man, the work is done, give me the money

Dumbledore: Harry, 60 points from Gryffindor for your bravery.

Harry Potter: Damn it, I almost died there, and you just give me some extra points and that’s it?

Dumbledore: ...

Malfoy: Pott, you shouldn't be hanging out with those mudbloods, the disgrace to purebloods.

Harry Potter: Go away, company dog, oh no, puppy

Priest: Harry, I have a big order that I think you can take on.

Harry Potter: Dad, don’t you always ask me to handle your big orders internally?╮(￣⊿￣)╭

V: Harry, you, want to go to Arasaka Tower with me and cause a scene?

Harry: You hit the nail on the head. Let the year 2023 bring back the past, V. Let's burn Arasaka Tower to ashes!

Mann: Harry, how are you? (He leans forward) Um, that soothing agent you have...

Harry: It's the soul... Never mind, I'll give you a 30% discount for Rebecca's sake.

Rebecca: Harry, explain why you stood me up last time, honey~ (pulling out the iron gall)

Harry: I, um, I said I traveled through time, do you believe it... Don't load the gun!

Left at his aunt's doorstep, baby Harry Potter arrived in Night City after a mishap. Raised by Father Sebastian, he became a "special" mercenary for the Valentino Gang. But after a mission, he traveled back to his original world, and a line of small words appeared on his prosthetic eye: Shuttle Energy, Accumulating...

The incomplete fragment of the artifact carried a soul to the magical world we imagine, albeit a little too early. Voldemort was still Tom Riddle, Snape's mother hadn't been born yet, and the original Dark Lord was still striving for the greater good.

The male protagonist has no CP in the main text, but there is ambiguity in the early stage. Support ggad, Sili
