In the Northern Song Dynasty, there were smoke and clouds, and the rivers and lakes were empty. Liu Yin and Sheng Yun were both highly relied upon by the imperial court, but one maintained benevolence and the other used trickery. They were good friends in the past but eventually became antagonistic.
Liu Yun, the leader of Liu Yin Sect, has three disciples. The second apprentice's name is Liu Lifeng, an orphan girl he picked up under a maple tree in his early years. Because the sect never accepts female disciples, she has tied up her hair and dressed as a man since she was a child, practicing martial arts as a man, hiding her daughter's attitude, and only standing with a maple sword.
As the dispute between the two families gradually arises, the conspiracy is getting closer and closer, and the Jianghu and the court are involved in the turmoil. In it, Liu Lifeng not only has to face the life and death of the sect, but also has to find her own chivalrous path between identity, friendship, and good and evil.
Philosophy: In the turmoil of the court in the Northern Song Dynasty, Shouren broke through the conspiracy and walked out of his own chivalrous way as a woman.
