An ordinary delivery boy who was accidentally struck by lightning and traveled across time was bound to the "ascension system" of a sand sculpture. In the bizarre world of cultivation, he started as a delivery boy and relied on modern thinking, clever operations and a little bit of luck (often missing the chain) to upgrade all the way to fight monsters, deliver goods and run errands, and make friends with strange people. In the end... He might become the leader of food delivery in the fairy world, or simply open his own "SF Express"?
