Su Yuan's transmigration into a cultivation realm where deliverymen soar on flying swords brings an unexpected gift—the awakened Chaos System. This demonic force operates by a single creed: seize treasures, steal opportunities, and consume others' fortunes. The system drives his advancement through task mechanics and demonic rewards, with the coveted Brahma Purifying Demon Heart dangling as his ultimate prize. His demonic nature manifests in the mundane: when confronted about missing food, Su Yuan's casual deflection exposes his true inclinations. Navigating a world of rigid cultivation laws with a system designed for chaos, Su Yuan becomes the unpredictable force that challenges everything the cultivation world holds sacred.
