Siying, a disciple of the Hehuan Sect, has a cowardly yet cute and timid personality, and her assessment results have always been at the bottom for five years after entering the sect. To complete the sect's trial, she mistakenly saves and brings back Wei Hanzhi, the severely injured young master of the Ruthless Dao. To cope with the assessment, she pestered and begged him to cooperate in acting, and in getting along, the two constantly tested and pulled each other. After learning his true identity, Siying fled in panic. Reunited in the secret realm, through crises and misunderstandings, the aloof sword cultivator breaks the shackles of the Ruthless Dao and confronts his inner emotions. Coming full circle, this bickering couple finally joins hands to stay together, opening a romantic xianxia romance.
