(Also known as: The Undying Night Emperor and The Undying Emperor's Son-in-Law)
Standard version: At the age of eleven, the young Ye Xuan's soul traveled through the ages and returned to a distant mythological era. He became an undying, indestructible monster, emerging from the ancient burial grounds of emperors and influencing one era after another. Yet behind Ye Xuan, an invisible hand was manipulating it all. To seize control of his own fate, Ye Xuan gave everything he had. But just as he was about to succeed, his apprentice and wife betrayed him, causing his soul to sleep for ninety thousand years.
When Ye Xuan awakens, he discovers that he has returned to his own body and become the live-in son-in-law of the Huangji Immortal Sect. Everyone even takes him for a fool. And so the story begins.
An emperor's soul from time immemorial returns in a single night.
From that moment on, a peerless son-in-law rises, beginning an invincible legend that sweeps through the ages!
Concise version: A foolish live-in son-in-law returns in spirit, rises in a single day, and becomes invincible through the ages.
Bragging version: "I'm invincible. Do as you please." Ye Xuan.
Meme version: Back then, I walked with my hands in my pockets, not knowing what it meant to have an opponent.
