Kirin Mountain

Kirin Mountain was a mountain owned by the Xuan Ji Sect.

Ten thousand years ago, Yan Mo Ge "punished" one of his servants, a kirin named Xiao Huo, by sealing him inside the mountain, though in actuality, he just didn't want to admit that he wanted to help Xiao Huo claim the inheritance of his people from said mountain.

Xiao Huo's aura caused gold and silver crystals to form throughout the mountain. The Xuan Ji Sect established mining operations, and Kirin Mountain became their greatest resource.

The crystals at the entrance thinned out, and most disciples did not dare go deeper into the mountain for fear of getting lost.

Yan Mo Ge ultimately released Xiao Huo. In retaliation for the Xuan Ji Sect's repeated bullying of Feng Lian Wan, he also caused the mountain itself to vanish and all of the gold and silver crystals to return to the kirin, dooming the sect to impoverishment.
