[Based primarily on the Harry Potter movies, with some FGO elements added] [The author received guidance from Rowling; this is not random writing or based on assumptions, so please read with confidence!]

[The main character will not become the Saber King; there will only be a few chapters where he/she becomes a girl for fun. I couldn't think of a better name at the time, so I just used this one. The name will be changed after the book reaches 200,000 words. If you mind this, please don't read on. I'm very sorry!]

When Lynn was reborn into 20th-century London, he thought he was living the life of a protagonist in a rebirth novel.

But tell me, what the hell is magic in this world?!

As Lynn gradually accepts everything and prepares to enroll at Hogwarts to learn magic and fight Voldemort.

Tell me what the hell a magic circuit is!

Fate is here, right?! Does that mean we'll have a Holy Grail War next?

Screw the Type-Moon universe, I'm quitting, I'm giving up!

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

HP+ The Sorcerer Supreme, single female lead Hermione, with a system

In 1991, while the new students at Hogwarts were struggling with the Levitation Charm, Silas Killer of Ravenclaw could already casually open portals. This seemingly "Muggle-born" new student had actually awakened as a time traveler at the age of seven, carrying a head full of knowledge from the original stories and a "system," and moved into the magical castle four years ahead of schedule.

He disliked the wand for restricting his nature, and instead conjured light shields and lightning bolts with his bare hands. While others dodged trolls, he countered with an Avada Kedavra, forcing Dumbledore to seek him out for a chat.

Silas, possessing dual magical abilities and an unparalleled talent for witty remarks, becomes the biggest plot hole in the Harry Potter world. His Hogwarts experience is a collision of tradition and subversion, a legendary journey for a "prospective Sorcerer Supreme."

Joel Hemis always thought of himself as an ordinary druid. Until he was eleven, when he received a letter delivered by an owl—and from that moment on, he became a proud little magical owl. ...That school year, the Forbidden Forest welcomed a Patronus. By the time all the teachers and students of Hogwarts realized what was happening, they were already surrounded by the Forbidden Forest! Until one day, the mysterious man came knocking—Joel: "Sorry, I just want to plant trees in peace and quiet, I don't want to fight!"... [P.S.: This is a lighthearted story about going to school and happily planting trees...No need to have read the original books.]

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?

[This is a lighthearted story; the protagonist has no morals or limits.]

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!"

(No system + single female lead + slice-of-life)

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.

[Invincible protagonist][HP + MCN + Harry Potter: Magic Awakened + other magical world][Ruthless system novel][Humorous]

Young An Ang travels to the magical world and, after many hardships, becomes the Sorcerer Supreme. Just as he is about to take control of Kamar-Taj, he suddenly receives an owl from Hogwarts and awakens a heaven-defying system. As long as he completes the heaven-defying tasks, he will receive unexpected artifact rewards.

An Ang smiled. It was time to give the magical world a little shock from the Sorcerer Supreme!

Why did the Savior change from a man to a woman? Why did Professor Snape cry during class?

Why does Professor Quirrell keep getting elbowed in the back of the head by giants?

Why is Professor McGonagall obsessed with mysterious plants? What kind of bizarre quest is "Educating Hermione"?

Why did all the Death Eaters suddenly start clamoring to quit overnight?

How will this terrible darkness, which threatens multiple magical worlds, end?

It all started on the day that the Venerable Master An Ang entered the academy.

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.
