西施
It is revealed that Aqing learned her skills while playing mock sword duels with a white gibbon. Fan Li allows Aqing to train the soldiers of Yue in swordsmanship. Aqing gradually falls in love with Fan Li. King Goujian of Yue finally defeats his rival, King Fuchai of Wu, after enduring hardship and humiliation. Fan Li is reunited with his lover Xi Shi, who was sent as a concubine to Fuchai. Aqing intends to kill Xi Shi but is taken aback by Xishi's beauty. Aqing accidentally hurts Xi Shi with her inner energy while thrusting her sword towards Xishi, even though the blade did not touch Xi Shi at all. She clutches her bosom in pain and the expression on her face is described as "so beautiful that it will take away the soul of any man who looks upon her". This is the origin of the Chinese phrase "Xizi clutching her bosom" (), which refers to a woman's beauty being enhanced when she is in a state of distress or agony.
