Kohler, who lives in a London industrial wasteland, lives with a madwoman who is obsessed with finding magic. Kohler once firmly believed that she was insane.

However, one day, while being chased by a British gentleman, he bumped into a "wall" that turned out to be a bar where everyone was a wizard. It turned out that magic really existed in this world!

But why do they all call him "Harry Potter"?

There was no other way but to pretend to be the savior.

While at Hogwarts, I awakened the Middle-earth Survival System, but something about the system was a bit off… [You received your Hogwarts acceptance letter—Main Quest: The Fellowship of the Ring!] [You didn't go to Gryffindor, but instead joined the Hufflepuffs, a bunch of gluttons—Reward: Hobbit Racial Talents (Stealth + Gluttony)!] [You refused Malfoy's handshake—Reward: Strength +1 (That's how you deal with fallen elves!)] [You wielded your wand powerfully—Reward: Two-handed Sword Strike (Magicians should have some Strength)!] The system actually thought I was in Middle-earth from Lord of the Rings?! …Years later.

Before the Dark Lord could even finish reciting Avada Kedavra, Rowe Baggins was already in front of him, wielding Narsir, and with a backhand…

"You'd better find something to eat before dark." This was the first thing Kane heard after running away from the Dursleys. Okay, I knew I hadn't completely escaped the Famine world... but thankfully, his ability to manipulate his shadow in Famine still remained, not only saving him from starving to death after running away and being killed by invading shadow creatures at night, but also bringing him other benefits in this world.

Dumbledore blushed and quickly snatched the envelope from Kane's hand, replacing it with another. A Hogwarts acceptance letter, this time it's right.

From then on, Tang Yan and his companions embarked on a path of resource cultivation. Starting with just two hands, resources were all obtained through plunder. [Harry Potter Tang Yan]: "What Voldemort Horcrux? It's clearly the essence of magic!" [Mr. Zombie Tang Yan]: "The old man was afraid of fire? No problem, I'll dismantle it into spiritual essence and yin-attribute luck." [Under One Person Tang Yan]: "What Quanxing? It's clearly spiritual material!" [Armor Hero Tang Yan]: "This is no ordinary monster, we must strike hard!" [The Boys Tang Yan]: "What superpower...

Docroft Evans, a transmigrator from the Muggle world, finds himself as the older brother of two special sisters: Lily, who possesses amazing magical talent, and Penny, who yearns for magic but cannot have it.

When his Hogwarts acceptance letter arrived, he embarked on his wizarding journey. Unlike in the original story, he met the lonely Severus Snape in his childhood and decided to protect this misunderstood boy in his own way.

That year, the werewolf howled, and he died in the Screaming Shack.

That year, golden energy accompanied by a whooshing sound like rusty gears grinding, the dead returned to the realm of the living.

Revenge? Retaliation? Or forgiveness?

Wizards become Muggles, and Muggles become wizards—should they disappear or merge?

Upon returning to England, he receives an invitation from Hogwarts. Considering it's likely they want him to continue in his old profession, Carl initially wants to refuse, but Dumbledore offers him an offer he can't refuse: a professorship in Alchemy plus a letter of recommendation from Nicolas Flamel. Carl readily agrees and randomly chooses an inn in Hogsmeade the day before, expecting to start work smoothly. But then, an unexpected incident occurs: a love potion mix-up leaves him tightly bound to someone. However… Carl says, he doesn't dislike her, he even likes her?

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...
