I Became the Villainous Ancestor After 10,000 Years

Transmigrated into a cultivation world as an ancient elder, Qin Lan gets locked in a system space for ten millennia. When he finally breaks free, he discovers he's become the legendary ancestor of a notorious villainous clan. With overwhelming power and zero moral constraints, he unleashes chaos upon the world. "I'm done being human!" he declares, commanding his descendants to pillage entire cities. Chosen Ones cower, sects flee, and the cultivation world trembles at the return of the Great Demon. This is the rise of a true villain—ruthless, decisive, and unstoppable.
