The ending of Celestial Bane, Biyao is dead, I'm always confused. Immortal Slaying was a wuxia novel written by Xiao Ding. It was about the love story between the protagonist, Zhang Xiaofan, and Biyao. In the ending of the novel, Biyao sacrificed herself to protect Zhang Xiaofan so that Zhang Xiaofan could finally complete his mission successfully. This ending was rather shocking but also somewhat regretful. Although Biyao's death was unacceptable, the plot arrangement in the novel was also a form of artistic expression. Through elements such as death and love, the novel shows the impermanence and fickleness of life, but also the fragility and preciousness of life. Therefore, although Celestial Bane's ending was heartbreaking, it also had a certain value and significance.
