Skull Mountain got its name because the mountain resembles a skull. It was a place of extreme Yin energy, thick with malevolent aura, making it an absolute feng shui treasure trove for cultivators specializing in that Dao.
There were two immortal caves on the mountain, inhabited by Shiji and Mayuan.
Inside the Black Yin Cave, a Daoist sat cross-legged. He had a green face, protruding fangs, and looked extremely ugly. A string of human skull prayer beads hung around his neck, making him appear fierce and terrifying.
