Purple Cloud Palace, deeply hidden within the Giant Eye of the South Sea, was surrounded by an underwater mountain range with intricate terrain, hosting numerous marine plants and teeming with a variety of fish and shellfish.
This Immortal Palace was built by the Golden Mother of the Heavenly Ones. The Heavenly One generates water, and in the Five Elements, metal gives birth to water, hence she was known as the Water Mother. Her proficiency in refining True Water earned her the title Heavenly Water Mother. In the Shushan World, there was another mighty figure known as Water Mother, named Ji Xuan, who was the master of Yan Yingmu before she attained enlightenment. Ji Xuan had her Water Mother Palace at the bottom of the North Sea, where she secluded herself for secluded cultivation, appearing rarely.
