Fifteen years ago, the famous "Shuanghua Sword Sect" was bloodbathed by mysterious forces overnight. The head couple Ning Yuanshan and Su Yingxue died tragically, but the young daughter Ning Shuanghua was rescued by a loyal servant.
Ning Shuanghua was adopted by Master Hanmei. She practiced martial arts in Qinglian Temple for fifteen years and mastered the peerless swordsmanship "Sixteen Styles of Shuangtian". At the same time, she secretly investigated the truth behind the family's destruction.
As an adult, Ning Shuanghua returned to the world under the name "Frost Sword" and met Xiao Yunlan, a young knight-errant. The two had never known each other before, and gradually fell in love while tracing clues.
As the investigation deepened, Ning Shuanghua discovered that behind the massacre, there was a huge conspiracy involving the collusion between the royal family and the scum, and Xiao Yunlan's life experience was inextricably linked to this grudge.
Ning Shuanghua finally found out the truth, killed the enemies who participated in the family extermination, avenged her parents, and at the same time revealed a larger conspiracy.
