Delivery Boy, but He Delivers Orders from King of Hell

Shanghai is a huge, living, and very "volume" city. Underneath its apparent prosperity, there is a supernatural ecosystem that is more complex than the backend system of "Ele. Me". Various "old ghosts" and "new souls" are stranded in the world due to obsessions, land leases, developers and other issues, forming intricate "ghost relationships". And our protagonist, the delivery boy, is the "ferryman" who travels between the two worlds - except that the ferry is not a boat, but a battery car; the one charged is not a ghost coin, but a delivery fee.
