This novel aims to revive traditional mainland wuxia and bring back Jin Yong's style of writing. The Book of Han records that during the Jianping era of Emperor Ai of Han, a man in Yuzhang transformed into a woman, married, and had a child. People believed this story was a historian's satire of the politics of the time, and that the tale of a man becoming a woman had been fabricated. But during the Northern Song dynasty, the Liao envoy Mi Jiazi, while passing through an unnamed village on the outskirts of the capital, witnessed a man turning into a woman. This brought to light a story unknown to the martial world...
A hundred years later, Gao Xiying, a farmer's son, stumbles upon a diagram of acupuncture points. After practicing its techniques, his body undergoes a strange transformation. He follows Master Taoye from Taoye Ferry in search of a famous doctor, and along the way becomes entangled in a romance with Master Taoye and Wang Ziqing, the swift sword of Jiangnan. He also unwittingly rescues the heroes of the martial world, stirring up a storm across the land and indirectly shaping the fates of the newborn Shen Gufeng, Song Wuyou, and others. Shen Gufeng and Song Wuyou were betrothed by their parents when they were children, but each has a destiny of their own and a heart set on someone else. Their unyielding journeys to find themselves unfold into an immortal legend of heroes from the Northern Wastes.
