Variations: Twisting-Turtle, Round-Turtle, Xuan-Turtle
Xuangui, or Twisting-Turtles, are found in the Strange River, east of the Niu-Trees Mountain. They are black turtles with a bird’s head and a viper’s tail, and they make sounds like that of splitting wood. Wearing a piece of xuangui from the belt protects from deafness and calluses. Mathieu compares it to the Japanese water turtle Clemmys japonica.
It is unclear what, exactly, is strange about the river.
