Eastern Azure Dragon Continent, Yin Moon Palace:
Su Ya–whose hair was now white and black–was in a deep cultivation state as she closed her eyes. She constructed a deep and elaborate illusion. She separated the illusion into two layers:
In one of them was a version of her with cultivation while the other layer was a mortal. However, in both layers, the two versions of Su Ya will undergo catastrophe after catastrophe, and their only purpose is to survive.
She created elaborate ways for her two selves to die over and over. And every time they found a way to survive the current catastrophe, another one would appear and the process would repeat itself.
During her cultivation, the death in the illusion resulted in her actual death in real life. However, the Heavenly Dao Protection would activate itself and brought her back to life and in perfect shape.
This was the way that Su Ya was created to cultivate one of the 6 Desires: the desire to survive.
