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

[Slice-of-life story + no female lead + research]

Lin Yi, whose love for astronomy is etched into his soul, is born into the HP world with all the knowledge from his previous life and a super brain that can "remember everything he sees".

He thought he could easily become an academic star in the magical world, but he discovered that wizards' understanding of the brilliant starry sky above them was still stuck in the primitive stage of "divination of good and bad fortune".

How can we tolerate this?

With a wave of his wand and a telescope in hand, his goal is to elevate astronomy from a "required, easy subject" to a "cutting-edge magical engineering" capable of changing the magical world!

From drawing precise star maps imbued with magic to developing powerful spells that draw upon the power of the stars;

From analyzing the probability theory behind divination to creating astrological artifacts based on constellations...

While Voldemort and his followers were still obsessed with pure-blooded people on Earth, a scholar under the stars was quietly turning the entire universe into his magical laboratory.

This is the story of a hardcore academic genius who, in a magical world, uses scientific thinking to climb the magical technology tree, and incidentally crushes everyone else in the process.

[Beast Girl][Resolving Unresolved Issues][Aside from a few major events, the author will do whatever the readers want, focusing on spoiling the fans][Author of two HP fanfiction works rated 9 or higher, please enjoy with confidence] Errol is the Weasley family's owl, but because she is a Ullnir owl, the male and female plumage are similar, so no one knew she was actually a female bird. The Weasley family even gave her a male name. Lin Hui accidentally transmigrated into Errol's body, while old Errol had his soul replaced that day. Lin Hui possesses the superpower "Fingertip Universe," which allows her to weave reality, but the problem now is—she is an owl, without fingers. Therefore, she must first learn Animagus to regain human form before she can use her superpower—no, that's not right, Errol is already too old to live, before learning Animagus, she must first survive! Damn it, she's only eleven years old, yet she has the same troubles as Voldemort!

Li Wei, a Chinese, entered Hogwarts in 1971 and graduated from Slytherin House. Twenty-one years after graduating from Hogwarts, he was accused of "spreading and proliferating the Dark Arts" and, after defeating nine Aurors sent by the British Ministry of Magic to arrest him, was personally summoned by Dumbledore and forced to become the new Defense Against the Dark Arts professor. "First-years, Professor Hooch, who is in charge of flying, told me that she is not feeling well today, so both flying classes this afternoon will be replaced with Defense Against the Dark Arts. The same applies to second-years; Professor Trelawney, who is in charge of Divination, senses that her fortune is not good this month and she is not suitable to teach. For the next month, you will not need to attend any Divination classes. Please remember this and make sure you don't go to the wrong classroom." "NO!!!!!!!!!...

The rating is low at the start, don't be scared away! I solemnly swear, this is a divine herb, not poison. Transmigrating to the HP world, Luke awakens the Magic Chef System, harvesting emotional points with delicious food to exchange for rewards.

As for learning magic at Hogwarts? Sorry, you can freely exchange for spell learning speed, potion-making skills, and alchemy experience. With a system, you can really do whatever you want.

Thus, the teachers and students of Hogwarts witnessed the terrifyingly strong yet seemingly unorthodox freshman Luke.

[Congratulations, host! Your Magic Hawthorn Candy Balls have successfully garnered 1000 positive emotion points, easily earning you the Beginner Transformation talent!]

Minerva McGonagall: Didn't the principal say you weren't good at it? You learned it in the time it takes me to twist my hip?

[Congratulations, host! Your magically spicy hot pot has successfully garnered 10,000 positive emotion points, instantly transforming you into a fire god in half an hour!]

Dumbledore: To be able to perform such a move with just a slight glance at my notes... perhaps he's more suited to it than Harry...

[Congratulations, host! Your Magic Lamb Skewers and Lamb Kidneys have successfully garnered 10,000 negative emotion points. You can claim the Dark Lord's Three-Piece Set without any side effects.]

Voldemort: You're just a little wizard from Badger Hill, why aren't you doing your job properly and learning dark magic? Don't I have any dignity?

...

When everyone's stomachs took the shape of Luke's, his magical talent and strength skyrocketed. A chef? Call him the God of Cookery!

The Death Eater was stunned: Oh my god! Run!

He is the real demon king!

Who has ever seen someone catch Avada Kedavra with a spatula?

Having transmigrated to the Harry Potter world, Charlie White is bound to the [Tyrant System].

By engaging in tyrannical behavior, you can earn Tyrannical Points and draw prizes infinitely!

While Hermione was studying her textbooks in the library.

[Ding! His Majesty's sleeping posture in class is practically a reincarnation of Hu Hai, perfectly embodying the behavior of a tyrannical ruler who "neglects state affairs"! Reward: Tyrannical Ruler Points +100!]

While Harry and Ron were training hard for Quidditch.

[Ding! His Majesty has been extravagant, purchasing all the desserts in Diagon Alley, in line with the behavior of a "tyrannical and hedonistic" ruler! Reward: Tyrant Points +500!]

Charlie casually did a ten-pull!

[Congratulations, Your Majesty, on obtaining: Animagus (Selectable Form)! +1 Free Talent Point, +1000 Proficiency in Fiendfire...]

Dumbledore: "Mr. White is the most gifted student I've ever seen, but unfortunately he just doesn't like to study..."

Voldemort: "Why? He learned the dark magic I painstakingly studied just by yawning?!"

Charlie lay on the sofa and sighed helplessly, "I don't want to either, but the system is giving me too much!"

Laudgreen displayed his extraordinary magical talent as soon as he entered Hogwarts.

Potions is easy to learn, but most of the finished products can only be drunk by animals. Snape regarded him as a fool who tarnished the great potions.

Transfiguration can easily turn inanimate objects into living things with their own thoughts, but it is powerless to do the opposite, which greatly puzzled Dumbledore.

In the study of spells, the spells cast by Lord always have some strange effects.

He only had no problems with Potions and Magical Creatures, and the magical creatures even regarded him as a child of nature.

Everyone praised him, saying he would become the next Newt Scamander, but he stuck to his profession.

Laudgreen: Although I am a master of Transfiguration, my spells are incredibly creative, and the magical creatures trust me, I am actually a botanist.

Evan has time-traveled once again.

His first time traveling was from Earth to the D&D world, where he went through trials and tribulations and became a sorcerer of the Universal School.

However, a fierce battle ended his second life.

When Evan opened his eyes again, he was surprised to find that he had once again traveled to a magical world that was both familiar and strange.

An owl flapped its wings and flew swiftly, delivering his Hogwarts acceptance letter, but the timeline he arrived in was 1971.

In 1971, a turbulent era, the Demon King was stirring, the Phoenix perched high in the castle, and the towers of Nurmengard remained tightly shut.

And those future heroes—Lupin, Sirius, James, Lily, Snape… at this moment, they are just innocent teenagers, unknowingly walking into the vortex of fate.

This is a glorious era, though not detailed in the original work, it is equally magnificent and filled with brilliant stars.

However, for Evan at this moment, the first thing he needs to solve is how to restore his spellcasting ability in this world without a magic network and with scarce magic power.

Or perhaps, he could go even further, relying on more advanced magical research concepts, gathering a group of intelligent and powerful companions, and launching a magical revolution that would change the entire magical world.

In any case, the times are waiting for Evan's actions.

-----------------

The timeline is set in 1971, in the same year as Sirius Black, Lupin, and Snape. The protagonist has mastered the spell system of D&D, has no system, breaks up the original pairings, is slow-paced, not mindless, and will seriously consider the plot.
