"Again, it's the second time! Has the grand master gone mad?"
It is said of the three souls in humans: Fetal Light, Shuangling, Netherworld Essence; and seven spirits: Corpse Dog, Fu Shih, Sparrow Yin, Swallowing Thief, Non-Poison, Filth Cleaning, Stinky Lung.
This Taoist Skill, derived from the "Spirit and Body Unification" technique, allowed her soul body to divide seven times, creating seven independent avatars.
Last time she "cut her feet to fit the shoes," using the activated [Elephant Head Vajra Stake] as a medium, she divided out the Sparrow Yin, which controlled her own reproduction and desires among the seven spirits.
She ultimately became the Beast Daoist Master Elephant Head Ming King, initially gaining freedom, permitting her avatars to move between the worlds of Yin and Yang freely.
But this time, she divided out the Filth Cleaning, which represents the "malicious thoughts" and also the source of all evil thoughts in her "Self."
