Dong'er fled Yao Ling Cave in search of Wuei, unaware that her twin sister, Ling'er, had also left the cave. They were both pursued by the authorities in Fuyang County for being fox spirits. Dong'er was caught in the midst of this turmoil, facing life and death. 　　Wuei, knowing that Dong'er was being hunted as a fox spirit, chose to defy his duty and let her go. Love and duty conflicted in his heart, causing a profound change within him. Unbeknownst to him, it was the influence of the fox spirit blood in his veins that made him infatuated with Dong'er. 　　Ling'er's fanciful ideas not only put Dong'er in a life-threatening situation but also led to her own condemnation by society. However, since learning of Xubu's disdain for her, she wanted to change and become more like Dong'er, but Xubu's heart was always with Dong'er. 　　Xubu admired Dong'er's simplicity and kindness, silently loving and caring for her. However, just as he gathered the courage to confess his feelings to her, he discovered that his esteemed senior and he himself had fallen in love with women of the same name.
