Modern cities are linked to the underworld. "Special groups" such as ghosts stranded in the world, spiritual cultivators, violators, and people with supernatural powers need exclusive supplies. This has given rise to the underworld takeout industry, with Lao Lu's "Human Unsubscription Service Center" (disguised as a funeral supply store) as a transfer station.
The protagonist, Gou An, delivers food and is involved in supernatural incidents. He balances the order of the world with the rules of the underworld, deals with the supervision of the 507, accountability from the underworld, and the chaos caused by malicious spirits, and grows up in fishing and saving the world.
