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!

[Otome + group favorite + hilarious + child-generation + parent-generation + multiple male leads] Travel back in time and become the whimsical Luna Lovegood. By day, you're a diligently studying, self-consciously guarding your vest. By night, you're a Hogwarts ghost, traveling through time and space. Luna's tangled love story with talented wizards unfolds. Otome warning! This is an otome novel! Not a drama! Avoid Leon!

Snape: You mean... you are my future woman?

Sirius: Why do you keep looking at that old Bat?

Lupin: Thank you for being my friend.

Fred: You're definitely the best prankster in Hogwarts!

George: Fred is right!

Draco: Why are you in my father's diary?

Cedric: You're pretty good... I think...

Wood: Who are you to say Quidditch is not elegant?

Riddle: Miss Ghost, it was me...who met you first...wasn't it?

Krum: Be my dance partner...ok?

Zabini: You barely meet... my aesthetic standards, right?

Nott: Can you give this to me?

(Otome + multiple male protagonists + sweet love + separate endings + parent generation + child generation) Lina, a male health expert, traveled through time to the magical world of Harry Potter and became Selina Lestrange, a therapist at St. Mungo's. She was also a crazy fan of Sirius Black. She took advantage of her position to go to Azkaban every day, but it was hard for her to "deepen her roots" in a field she was not good at.

See how she shakes off the label of "star chaser" and "rebuilds her reputation" at St. Mungo's! And wins everyone's love (mistake)!

Sirius: That woman has changed! How come she's still... pretty?

Snape: I don't have that disease, thank you!

Lucius: I heard that you can help me give birth to a daughter?

Bill: Thank you for your care every time

Barty Jr.: You saved me, my life is yours...

Please look forward to more male protagonists——

[All-star + Popular + Breaks Up Official Pairings + Personalized Settings + Brainless] Orion Malfoy, Draco's younger brother, possesses an angelic face bestowed upon him by Merlin, enough to leave everyone speechless, and a mischievous heart that enjoys watching others rage. A spoiled and unruly boy.

He imagined his daily life at Hogwarts would consist of: using the sweetest smile to carry out the most ingenious pranks, making Longbottom cry with his brother, and enjoying Malfoy-style privileges and luxury.

However, things seem to have taken a bit off track?

Why do some people blush and feel their hearts race instead of getting furious after he plays a prank?

Why did the twin brothers whistle and give him candy after he mocked "poor Weasley"?

Why did his attempt to trip up the savior result in a stammering Christmas gift instead of a glare?

And Professor Snape, with that complicated look in his eyes, was he trying to lock him up or brew him a health potion?

Orion looked at the increasingly bizarre "heartthrob" script, tilted his pretty little head, and revealed a naive yet wicked smile that could make any professor's heart skip a beat: "Oh? This seems... even more interesting?"

He was at Hogwarts, and had just become a Half-Blood Prince.

…

In 1976, 16-year-old Severus Snape welcomed a new life.

That year, Voldemort had not yet split his soul into seven pieces.

That year, Nagini was still hiding in the forests of Albania.

That year, Pandora was still doing wonderful experiments at Hogwarts.

That year, Ms. Rosmerta was in her prime and very graceful.

That year, Snape decided to experience this wonderful world.

First grade, Horatio: Headmaster, look, use this scythe of mine to hook out the soul, then lock it in this lamp and roast it with the fire.

Second grader Horatio: Principal, look at this cabbage! It can increase in value infinitely and even kill the basilisk in an instant!

Third grader Horatio: Principal, do you think this soul contract could arm the Dementors into my army of Soul Reapers?

Fourth grader Horatio: Headmaster, look, this gravity magic can pull down meteorites from outer space to strengthen Durmstrang and Beauxbatons College.

Fifth grade, Horatio: Principal, you said if I projected this mark onto the moon, everyone who saw it would be brainwashed into a believer in houttuynia cordata, and the houttuynia cordata I planted in the Forbidden Forest would sell like hotcakes.

Sixth grader Horatio: Headmaster, look! The tree that grows from this seed can convert cosmic energy into magical seeds. Then all of humanity can become wizards, mastering both technology and magic. Conquering the stars will be just around the corner!

Seventh grader Horatio: Principal, look...

Dumbledore: "Enough talk. Take out your wand. It's either you or me today."
