I Became the Demon Emperor in Hiding, Then the Immortal Empress Confessed Her Love

Su Baiye wakes up in a cultivation world as the doomed Abyss Saint—destined to be betrayed, stripped of his spiritual bone, and imprisoned for eternity. But he's got a system and a plan: lie low for ten thousand years until he becomes the Demon Emperor. When he finally emerges from the Celestial Demon Forbidden Zone, the last thing he expects is a confession from Ling Yanhan, the ruthless Immortal Empress who once stood against everything he represented. A slow-burn romance between former enemies, where patience pays off and sweetness comes after ten millennia of suffering.
