The level of magic determines the allegiance of justice. "Truth lies in the difference of magic; history is the hymn written by the survivors." Owen Carrot, looking at Voldemort and his Death Eaters standing before him, said calmly, "You are noisier than the wind; dance with the wind, endless wind." Watching Voldemort and the Death Eaters being swept into the air by the powerful tornado, Hogwarts fell into an eerie silence. Only when the young wizard who had been reading a book while walking disappeared did someone quietly breathe a sigh of relief. "I knew it. Even Voldemort can't break Owen's rules, or he'll be punished too." A Mr. Weasley, who wished to remain anonymous, looked at the people spinning in the wind, his expression not too good...

Roger traveled to the world of Harry Potter.

The game started on hellish difficulty; he became the apprentice of an old, powerful, and extremely temperamental dark wizard. Just as he was cautiously serving this unpredictable mentor, he unexpectedly discovered that the bio-computer he had developed in his previous life had also transmigrated with him!

From then on, Roger's magical training began with the three Unforgivable Curses! "Analysis of the Imperius Curse complete." "Begin observing Professor Quirrell."

Years later, when the Daily Prophet was preparing to write a legendary feature on Mr. Roger Lewis, prominent figures in the wizarding world spoke out:

Professor McGonagall (with a serious expression of amazement): "Without a doubt, Mr. Lewis is an unprecedentedly outstanding graduate in the history of Hogwarts." Dumbledore (his wisdom gleaming behind his half-moon spectacles): "I must admit that no one understood the nature of magic better than Roger. Not even the four founders of Hogwarts." Voldemort (in a complex tone): "It is well known that I made indelible contributions to Roger's magical research..."

Rita Skeeter (writing furiously with her quill pen, her eyes gleaming with gossip): "Mr. Riddle, was it the summer before Mr. Lewis enrolled?"

Voldemort (lost in memories): "Sigh...that summer, they invited me to participate in the experiment, though the method was crude...If they had said it was to develop an elixir of immortality, I could have provided tremendous assistance! I wouldn't have needed to go through the trouble of finding the Philosopher's Stone...I still deeply regret missing this opportunity to return sooner!"

Returning from the mysterious world, witch Harry only wants a peaceful life and to experience Hogwarts, this fairytale playground, firsthand. However, a certain self-proclaimed Dark Lord and some so-called "important figures" seem determined to prevent her from having her way. So, it's time to let the wizarding world know what true "calamity" really is. (Those who haven't read Harry Potter or Lord of Mysteries won't be affected.)

The protagonist, now Tom, has transmigrated again, this time to the world of Hogwarts. He's adopted by Luna and becomes part of her family. Tom, who thought he could only attend classes after his owner enrolled, receives an acceptance letter from Hogwarts on Luna's tenth birthday! Thus, a resilient, mischievous cat with some strange abilities enters Hogwarts as a student. No one knows what changes his arrival will bring to the wizarding world. (Updated at 12 PM as usual)

[Single female lead, Hibiscus, a genius protagonist. The story will try to follow Rowling's original character traits as closely as possible, though some elements may be added by the author.]

Having been reborn into the world of Harry Potter, Raven only wants to live a happy and joyful life with his family and friends.

So Hogwarts gained a little badger who always acted on his whims.

Harry: Where's Raven? I want to see if he'd be willing to help.

Ron: He seems to have gone fishing in the Black Lake.

Harry: But I just checked the Black Lake, and it's not there!

Ron: Maybe he went to have hot pot with Hagrid? He always says that having a fish hot pot after swimming is very comforting.

......

Dumbledore: Raven, you should continue to create a few more spells so that you have a very good chance of getting a Merlin First Class before your fifth year.

Raven: But Professor, I don't want to continue. I've become more interested in alchemy and fishing lately.

Dumbledore: Your interests are very varied.

Raven: Yes, but I feel like fishing will be a long-term hobby of mine. Those damn fish just won't bite. I think I need to learn some new techniques to deal with them.

......

Grindelwald: You possess the immense talent of Raven, you...

Raven: Sorry, Mr. Grindelwald, I'm not really interested in the greater good.

Grindelwald: But war between wizards and Muggles is inevitable.

Raven: Let the people who should be worried about this worry about it. I'll bend over if the sky falls.

Grindelwald: ......

The tallest tower in Nurmengard

This is a forbidden area for wizards throughout Austria and even the world.

At that moment, the cry of a baby with sunset-colored hair shattered the long-lost peace!

Grindelwald: Her bright smile will always inspire those who walk with her and light the way for the rest of my life.

A certain White Demon King: This little girl's childlike innocence and vitality are like fireworks in the night sky.

A diary entry: He is my salvation, my hope, the person who changed my life.

"Things you believed in during your childhood and the stories you experienced will become irreplaceable treasures."

"I believe that language has its own unique power, and there is nothing that cannot be solved by speaking it out!" said Xiaogong.

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?

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.
