[Sweet and heartbreaking, with no female rivals]
When heaven and earth first formed, the murky energy of the land took shape as a spirit: an evil spirit. It assumed human form and gained the power to devour. Though it was conscious, its devouring power could destroy all things without a trace.
To restrain it, the Goddess Nuwa used a stone from the sky to forge a spirit pearl. Its power could dispel the devouring force. Nuwa helped the pearl take human form and commanded her to stay by the evil spirit's side, calling it their heavenly mandate.
For over a hundred thousand years, the heartless evil spirit Wuxin kept the spirit pearl Ling'er company. Wuxin used his devouring power again and again, but Ling'er never killed him. Instead, she tried every way she could to purify him, because she had fallen in love with him. What a ridiculous heavenly mandate!
At last, one day, Wuxin could no longer control the devouring power within him. For the sake of all living beings in the Three Realms, Ling'er submitted to fate and killed Wuxin with her own hands.
Before he died, Wuxin offered his soul to the Book of Fate for Ling'er. He used his chance at rebirth to create two people: Leng Qianyue of the fox clan and Feng Xun of the serpent clan. He made a pact with Ling'er to meet again in twenty thousand years.
But nothing unfolded as Wuxin's book had written. Who changed their fate, turning a promise made for twenty thousand years into nothing...?
