Ye Xiao's spiritual energy encompasses the world; with his guidance, even chickens and dogs can attain immortality. However, every time an era changes, Ye Xiao will undergo a complete transformation and hide in a mortal body. Ye Xiao's disciple, the Female Heavenly Emperor, in order to protect the Holy Lord, deliberately establishes the Heavenly Sect to ensure its descendants guard the Holy Lord, awaiting his true awakening. As the Holy Lord remains in deep sleep, the Female Emperor steps in to fight on his behalf, defending against enemies from other realms, and disappears for a thousand years.
