The broken-tailed stone fox in the rundown ancestral hall is a taboo revered by everyone in Ye Family Village. Out of mischief, the young girl Ye Xiaoying used charcoal to draw two thick eyebrows on the stone fox, unexpectedly unsealing the fox king who had been imprisoned for a thousand years. A blood contract is forged, a clan-annihilation crisis descends, and she and he become the most awkward life-and-death partners. As bizarre incident after incident occurs, she gradually discovers that she and this fox demon, who hates her to the bone, had already forged an inextricable destiny a thousand years ago.
