Quick Transmigration: Villain Boss, Please Show Mercy

She's died and reborn ten times, and now she's done playing the hero. Armed with a system and a mission to collect soul fragments across infinite worlds, our heroine discovers a twisted truth: the cold, ruthless villain bosses guarding each realm are all incarnations of the same man. To complete her quest, she must get close to these dangerous antagonists—but mercy isn't in their vocabulary. Can she melt the heart of a villain who's destroyed her in every lifetime, or will she fall for the enemy she's meant to save?
