In the end of the Dharma era when the spiritual power of the fantasy world is declining, the protagonist Lin Xiaofan is accidentally bound to the "Supreme Express System of All Realms" and is forced to become a courier traveling through the heavens and all realms. His daily tasks include: delivering takeout (extremely spicy Mala Tang) to the Demon King who has been in seclusion for thousands of years, helping the Empress of the Immortal Realm purchase limited edition lipstick (paying the bill with the Nine Turns Golden Pill), and delivering the holy sword to kill the dragon for the brave man from another world (but the brave man always gives negative reviews). The express delivery rate will affect the recovery of spiritual energy in the real world. The faster the delivery, the stronger the spiritual energy in the world - so the life and death of the entire cultivation world depends on his five-star praise.
