Among the Myriad Heavens, I'm Really a Gentleman

I, Luo, have come to the myriad heavens for just three things: causing trouble, causing trouble, and more trouble! Sentimental Swordsman, Ruthless Sword: Hello, ex-hubby! I’m the top scholar, Little Luo! Wuxia world: On the night of the full moon, atop the Forbidden City, a sword comes from the west, a celestial immortal flies from beyond the sky! The sword is three feet and seven inches long, weighs seven jin and thirteen liang, and is built around uranium-235. It’s called the Depleted Uranium Great Sword. Please, have at it! High-Martial World: Yin Kui Demon Sect, Holy Maiden of the Immortal Sect, don’t move! I really am your master! Naruto world: I’ll trample both banks of the Pure Land and smash the Five Kage Alliance with my twin maces. I’ll defeat every opponent in the shinobi world and shake half the Naruto world! How can we possibly maintain peace in the shinobi world when we’re surrounded by these vermin?! My name is Uchiha Luo En, and I’ll beat the villagers till they squeal! Marvel Universe: Do you think you can come and go from Kamar-Taj as you please? You’ve offended the Sorcerer Supreme and still think you can leave? The thirteen bronze warriors of Kamar-Taj, form up! DC Universe: I’ll tread on Heaven and Hell and beat the DC multiverse with my club. Do you even understand the prestige of being the top enforcer in both Heaven and Hell? Investiture of the Gods world: By rights, a heavenly soldier of your rank isn’t qualified to question me. And one more thing: who put Yang Chan in my bed?! A man among the myriad heavens, never crashes!
