Yu Xian, a disciple of the Yunxuan Sect, and his junior sister Rouran were accidentally involved in a series of events such as the disappearance of a peerless sword and the unexpected death of the leader of the Chinese Sword Sect. Their childhood sweetheart, the junior sister Rouran, was attacked by a sneak attack and her life was in danger. The manipulator behind the scenes gradually introduced Yu Xian to the Kunlun Mountains to start the journey of becoming a swordsman. Can Yu Xian become a swordsman? What story will happen between him and his junior sister? Who is the manipulator behind the scenes? What's the purpose? Everything is complicated and confusing, and I look forward to readers and friends experiencing the love and hatred in the world of Yu Xian and Rouran Xianxia.
