Bai Lingxi, a fox demon from Qingqiu, seeks out "the general who pulls Dai Yu's finger" in order to repay his life. He mistakenly identifies the villain general Shen Jinghong and is rescued by his true benefactor - the border guard general Lu Zhaoyan. Lu Zhaoyan saw through her identity but protected her. In the process of fighting against the evil slayer and Shen Jinghong's plan, the two gradually grew from kindness to deep love, and resolved the estrangement between humans and monsters.
