Yinshiguideng

Core world view (Chinese orthodox ghost story) There is a gap between Yin and Yang in the world, and it is named Dengyin City. Mortals will stray into the underworld if they don't return home at night, walk on deserted roads at night, and break the taboos of their ancestors. The Yin market does not sell gold or silver, but only exchanges lifespan, memory, obsession, and the next life. Those who enter the market can either exchange one thing for one life and leave alive, or they can be left in the Yin market and become a guide with a lantern, ferrying the dead souls forever and never being reincarnated. And all the strange things in the Yin City are not caused by thin air - all ghosts are old friends owed by living people; all disasters are the evil consequences planted by living people.
