In ancient times, people were few and beasts were many. The beasts had spirits and could transform into demons. The demons wreaked havoc, and people lived in misery.
A man wearing a mask of yin and yang wielded an ancient black sword that exterminated evil and slew ghosts. He also founded the Yin-Yang Sect.
From that day on, these two sayings were passed down through the world: If you suffer at the hands of demons, ghosts, or monsters, someone will tell you, "The Yin Eye sees life and death; Yin and Yang determine the fate of the world. If you encounter ill fortune, seek out a Yin-Yang practitioner at once."
