The novel tells the story of the orphan Diao Chan, who is entrusted by her adoptive father Wang Yun with the important task of "supporting the Han Dynasty". She uses her peerless appearance as a sword to deal with the powerful Dong Zhuo and the god of war Lu Bu. An unexpected encounter in the back garden under the moonlight formed an indissoluble bond between her and Lu Bu, and also unveiled the prelude to the serial conspiracy. She cultivated two faces in front of the bronze mirror - Lü Bu's innocence and ignorance attracted his pity, and Dong Zhuo's coquettishness and charm attracted her greed. She used rain and tears in Fengyi Pavilion to intensify the conflict between the two, used the brocade robe sewn by herself to affect Lü Bu's mood, and finally helped Lü Bu kill Dong Zhuo. However, after her success, she did not gain freedom. Instead, she became a pawn in the chess game of troubled times. She moved from Dong Zhuo's cage to Lu Bu's phoenix crown shackles, and finally ended decisively in Cao Cao's Tongque Tower invitation and the Han Dynasty's "Royal Wine Commendation". The work depicts Diao Chan's torn relationship between loyalty and mission and personal emotions with delicate brushstrokes, shows the tragic fate of women in troubled times, exposes the cruelty and hypocrisy of power struggles, and composes an elegy about sacrifice, deception and disillusionment within the framework of history.
