The Villain Convinces with Reason [Quick Transmigration]

Yuan Buwei gets bound to a villain redemption system with one mission: whitewash his reputation across countless worlds. System 999's advice? Stay honest, don't cause trouble, and butter up the protagonist. Yuan Buwei's approach? Slice through problems with a sword while claiming he's just "reasoning" with people. From usurping tyrant to space pirate, from demon emperor to grim reaper CEO—he tackles each villain role with cheerful chaos, turning every world upside down while insisting he's the most reasonable person around. The protagonists never saw it coming.
