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!

Multiverse, academic genius, magic and technology, fast-paced leveling-up, multi-world travel, harem + conquest storyline

I was transported to the world of Hogwarts, and when I opened my eyes, I was a baby, and a baby in the wild at that.

Just when Lucas thought he was going to have to restart the game, Snape, who happened to be passing by, picked it up!

He became the adopted son of Severus Snape, the youngest Potions Master in the British magical world.

He grew up at Hogwarts; while others entered at eleven, he entered at five.

On the day I officially started school at age eleven, I awakened the essential cheat code for transmigrators: the plot-breaking system.

You can get system rewards as long as the storyline breaks down.

Hogwarts Express is collapsing! Draco has become enemies with Harry Potter, and the reward is a weapon with maxed-out proficiency!

The Sorting Ceremony has failed, but the reward is a top-tier, max-level potion talent!

However, as his strength increased, Lucas's daily check-in style began to change drastically.

Holding the Gryffindor sword, he rode on the head of the basilisk.

Lucas smiled broadly as he watched the fragments of Tom Riddle's soul float out of the diary!

"Come on, Tom, say 'cheese' to the camera!"

Voldemort: Why? Why? I already have the Elder Wand, how could you defeat me? Harry!!! Harry wiped the sweat from his nerves with his sleeve and said: Because I defeated you a hundred times in the game! Voldemort: What? What game? Defeat me a hundred times? Hermione: Shut up, or you'll be smashed to pieces! Harry, why do you never remember to finish off the boss?!

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!

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...

[Single female protagonist Hermione + no system + starting from the prisoner of Azkaban + mainly movies]

My name is John Merrick. In my previous life, in order to save someone, I faced the Hundred Ton King, and ended up traveling to England in the late 20th century.

Because I didn't have a system, I thought this was just an ordinary world.

But when I was 10 years old, I saw with my own eyes a car flying across the sky, and then two people who claimed to be from the Ministry of Magic came to my door. From then on, a fantasy magical world opened its doors to me.

Harry: The sky is falling, my family. A Ravenclaw actually got the recognition of the Sword of Gryffindor?

Hermione: I never thought there would be people more reckless than Harry and Ron...

Ron: I don't know, as soon as he comes, Hermione won't play with me.

This book is also known as "The Patriarch Who Likes Galleons Ran Away with the Potions Master Again" and features two male protagonists.

Severus Snape x Sirod Slytherin (with personal interpretations)

The isolated and helpless potions professor finally met his little rose, a story of black and white intertwining, confusion and fusion.

Upon entering school again, Sirod winked at Severus.

Severus: ...

Later, Sylvie asked, "Professor, do you believe in love at first sight?" while grabbing Severus's sleeve.

(There are parents and children. They are Tom's classmates. They don't like idiots and like Galleon. Severus will not like Lily and will only like Sir Lord.) (You can skip this if you don't like it.)

Dumbledore quickly grabbed Orion who was about to cast a spell.

He wiped the sweat from his forehead and said, "Alas~ It's not appropriate to do this in broad daylight. Fiendfyre is a powerful dark magic and can't be used carelessly!"

Orion nodded and said, "I understand, Principal. We can let him go if we carry some people on our backs, right?"
