Descriptions[]
As the saying goes, "The layered cliffs cast elusive shadows, to where treacherous roads lead, no one knows." In the ancient texts of Liyue, this place is sometimes referred to as the "Yu Valley." Even the radiant brilliance of the sun must sink into the deep shadows of dusk. Although legends remain mere legends, one should always expect the unexpected when exploring this labyrinthine underground mineshaft.
