Lin Mo, a 22-year-old delivery boy, appears to be a "good-for-nothing rider with a 99% overtime rate", but is actually the last descendant of an ancient family of immortal cultivators. The "Fairy World Delivery System" is sealed in his body - he must complete weird human orders (such as Only by giving "immortal grass that can stay up late" to otakus, and "photogenic jade that can slim down faces" to Internet celebrities) can the sealed spiritual power be unlocked, and the system comes with the attribute of venomous tongue-in-cheek (similar to "If you overtime again, the fairy world will give you a bad review").
