Dumbledore said, "I am your father."

Grindelwald said, "Bullshit, he's obviously closer to me."

Voldemort said, "You are the boss, I accept your position and I won't fight you anymore."

Everything is in Hogwarts: The Forbidden Son of the Black and White Demon King.

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!"

Hermione: "Merlin's lace stockings! This is the first time I've seen someone so eager to learn."

Blackley: "Knowledge is the most precious treasure in the world, and I am a goblin with an extreme greed for knowledge. So, Professor Dumbledore, can you really not explain the principle of the Killing Curse? I want to invent a counter-spell for the Killing Curse."

Dumbledore: “…”

Voldemort: "That little wizard is simply a lunatic. He actually wanted to capture me and dissect me for research! He is a lunatic!!!"
