In the Xuanmen Fantasy Sect, Xiaoshan is an inconspicuous orphan girl. After being picked up by her master, she lives under the knee of the cooking grandmother. She has mediocre qualifications and lives as female cannon fodder. She quietly takes care of the sect's chores and sews cotton clothes, hiding her tenderness in the details. Three years ago, in order to save his master who was severely injured by ancient monsters, Xiaoshan sacrificed Huilinggen. He lost the qualification to practice, but concealed the matter. During the battle between the demon sect, the devil's palm was directed at Ling'er, the group's pet junior sister. When everyone was retreating, Xiao Shan stepped forward, but his internal organs were shattered and he died. She thought death was the fate of cannon fodder, but she didn't know that this sacrifice tore apart everyone's pretense.
