You Say You're a Grand Archmage, but I'm an Immortal Emperor

【Western Fantasy + Cultivation + Lighthearted Comedy + Multiple Heroines + Truly Invincible】 After spending two thousand years cultivating immortality and becoming an Immortal Emperor, Ye Yun has traveled the world countless times and defeated every opponent under heaven. How is he supposed to while away the endless years ahead of him? After a full second of thought, Ye Yun comes to a conclusion: Why not go have fun in another world? And so, one day, a perfectly ordinary cultivation practitioner appears in a perfectly ordinary magic-filled continent. Then the whole world goes haywire... “Why is your lightning magic so powerful, yet there’s no sign you used any mana?” The Great Sage of the age stares in disbelief. Ye Yun: “Because this isn’t magic. It’s the Heavenly Thunder Art.” “What kind of move is that? How come I can’t move just because you said so?” A minor villain by the roadside looks terrified. Ye Yun: “Oh, that’s called Word Becomes Law.” “We were merely sparring. What do you mean by this?” The current Sword Saint breaks into a cold sweat as swords rain down from the sky. Ye Yun: “This is Ten Thousand Swords Returning to the Origin.” Years later, the hero who defeated the Demon King stands before God. Hero: “Am I now the strongest in the world?” God: “Of course.” Hero: “Even stronger than Lord Ye Yun?” God: “Ye Yun... It’s been a long time since anyone called me that.”
