From a broke kid with just three yuan and fifty cents in his pocket to the working-class Heavenly Emperor ruling over the Seven Realms! Mu Sheng unexpectedly picks up a lucky cat demon, setting him on a one-way road of raising demons, working odd jobs, making money, and protecting his family. Cleaning, deliveries, bringing in good fortune, security... There’s no job he won’t take, no matter how wild! The Demon Realm? Signed up! The Immortal Realm? Covered! The Origin Realm? Monopolized! Anyone who blocks his way to making money, ruins his peace, or lays a hand on his family gets dragged in to work until they learn their lesson! The world-ending overlord mops floors, the King of the End delivers parcels, the Rebel of Chaos hauls bricks, and the Root of All Evil cleans house!
