When a science PhD travels to Hogwarts, he discovers that magic is just another form of energy—as long as there is a theory, it can be quantified, copied, and enhanced!

From analyzing the structure of wands to developing magic circuits and energy arrays, he ushered the wizarding world into the "era of technological magic."

Voldemort was sent to the research institute by him, and Dumbledore asked him to give a public lecture on "Magical Physics".

However, this was just the beginning—when he broke through the dimensional barrier, new worlds began to emerge:

In Middle-earth of The Lord of the Rings, he single-handedly suppressed Sauron;

On the continent of The Witcher, he combines magic and runes through alchemy;

In the Marvel Cinematic Universe, he even got Tony Stark to come and get inspiration from him;

After Harry Potter, he will eventually become the supreme god of magic in all the heavens and the myriad worlds!

Daud Wick, who has lost his memory, thought he could become the best killer in the world with his time ability, but one day he entered the magic school Hogwarts, and thought being a wizard killer would be a good idea.

But time is determined by fate and is not in our control. The twists and turns of fate are far beyond the imagination of ordinary people.

First-year Nicolas Flamel wants to sign an unbreakable vow with him, and Grindelwald wants him to inherit the Saint

The organization I worked for before the second year directly sent people to break into Hogwarts and finally escaped unscathed.

In the third year, a behemoth that swept the world surfaced and declared war on the entire wizarding world.

What will happen in the future?

"The road to destruction is shorter than you can imagine"

So said the third generation Dark Lord of Britain, Dowd Wick.

(The first grade will probably stick to the original novel, but starting from the second grade, the plot will be original and completely subvert the original novel)

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!!!"

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

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...

When he comes to Hogwarts, where will the fate of this world go…

After many years:

Voldemort: Me? Dark Lord? Don’t talk nonsense! Be careful, I will sue you for spreading rumors!
