Having transmigrated into the last bloodline of the Grindelwald family, he initially wanted to live a low-key life, but was forced to bind himself to the "Underworld God System".

From then on, the style of Hogwarts completely went astray.

"Petrify everyone? That's too lame. Come and witness the power of our Zaun petrification!"

"Want to learn the Patronus Charm? First, pay protection money to the system. Avada Kedavra can turn a melon into a rainbow color for you."

Dumbledore looked at the savior, who had been turned into a "henchman," and fell into deep thought: "This kid...maybe he can form the most cowardly villain alliance in history with Tom?"

Until one day, I was cornered by the Dark Lord, and the system suddenly prompted me—"Hey buddy, there's only one guy on the other side, call for reinforcements to take him down!"

I, Li Gang, an indestructible physical cultivator, failed in my attempt to pass the tribulation and was reborn in a magic school called Hogwarts!

At the beginning, I was given a fire stick, and then I was asked to recite some bird language spell that I couldn’t understand?

Sorry, as the only physical cultivator in this world, I firmly believe that all beings are equal and can be "physically liberated." The end of magic is my fist!

As a result, the style of Hogwarts painting completely went astray.

The Sorting Hat trembled on my head. "Help! He's all brawn for brains!"

A Halloween monster broke into the ladies' room? Sorry, I'll take him down with a sliding tackle and a chokehold. Faster than lightning!

The thousand-year-old basilisk in the secret room wants to wrestle with me? I'll show it what "dragon tendons and tiger bones" mean on the spot!

Dementors want to suck my soul? My blood and energy will burst forth, like the sun in the sky, and I will roast you to ash!

The Triwizard Tournament requires taming a dragon with bare hands? I simply rode on its neck and asked it, "If I punch you, you might die. Do you agree?!"

When I smashed Voldemort's Horcrux with one punch, he was completely stunned.

Finally, Headmaster Dumbledore grabbed his snow-white beard and roared at me in despair: "I beg you to stop demolishing the school! Physical exorcism is prohibited at Hogwarts!"

He traveled to the world of Harry Potter and became Ron Weasley, awakening to an extraordinary level of enlightenment, which brought a bit of a shock to the magical world.

"Your comprehension is extraordinary. By visualizing the starry sky, you learned the Star Sword Technique, and with one strike, you can freeze fourteen continents."

"Your comprehension is extraordinary. By breathing while asleep, you've learned the Great Dream Breathing Technique. You can practice it while you sleep."

"You have an incredible comprehension. By observing, you learned the Animagus transformation and mastered the Seventy-Two Earthly Demon Transformations."

"Your comprehension is extraordinary. Through practicing the flying broomstick, you can fly with a sword and take heads from thousands of miles away."

Ron single-handedly killed the dragon, and Harry Potter said: "And my friend, you are the real savior."

Seeing Ron master all the spells, Hermione Granger said: "Genius is just the starting point for you."

Ron destroyed the city and split the sky with one sword. Dumbledore said: "My boy, you have shown me what real magic is."

Ron imprisoned Voldemort in the Horcrux, and Voldemort said: "I wish I had never been born."

Ron chuckled: "When I'm not practicing, you see me as the bright moon in the sky. When I'm practicing, you see me as a mayfly seeing the world!"
