Before the fox clan transforms into human form, they all must go to the mortal world to undergo trials. 　　The eldest sister was saved by a mortal; to repay him she descended to the mortal realm and became an empress who embodied maternal virtue for a lifetime. 　　The second sister's spiritual roots matured early; she cultivated in the mountains and became the fox clan's youngest elder. 　　As for me, I was saved by a mortal… four hundred years later I transformed into a young beauty weighing three hundred jin. 　　Within the fox clan I immediately lost the right to choose a mate. 　　So I entangled him for seven lifetimes, making him lonely through each life until old age.
