Lin'an Strange Things: Binding the Underworld Dungeon System at the Start

Era background: During the Shaoxing period of the Southern Song Dynasty (around 1150 AD), Lin'an City (now Hangzhou). This is a balanced world where history and myth are intertwined - the legend of the White Snake is happening, but the details are different from the folk tales; reincarnation in the underworld is real, there are ghosts on duty in the City God's Temple every night; there are occasional monks among mortals, and there is really a Dragon Palace under the West Lake.
