In Quanzhen, Yang Guo is often bullied by his fellow seniors, and discriminated against by his master, Zhao Zhijing. Yang Guo flees from Quanzhen and ventures unknowingly into the nearby Tomb of the Living Dead, where the Ancient Tomb School is housed. He is saved by Xiaolongnü, a mysterious maiden of unknown origin, and becomes her apprentice. They live together in the tomb for many years until Yang Guo grows up.
Yang Guo and Xiaolongnü develop romantic feelings for each other, but their romance is forbidden by the prevailing norms of the jianghu (or wulin, the community of martial artists). Throughout the story, their love meets with several trials, such as the misunderstandings that threaten to tear them apart, and their encounter with Gongsun Zhi, whom Xiaolongnü almost marries at one point.
Finally, after their reunion and marriage, Xiaolongnü leaves Yang Guo again, owing to her belief she cannot recover from a fatal poison, and promises to meet him again 16 years later. While Yang Guo is wandering the jianghu alone, he meets several formidable martial artists and a giant condor, and improves his skills tremendously after training from them. His adventures gradually mould him into a courageous hero and the most powerful martial artist of his time.
Yang Guo serves his native land by helping the Han Chinese people of the Song Empire resist invaders from the Mongol Empire. At the end of the drama, he is reunited with Xiaolongnü and they leave to lead the rest of their lives in seclusion after receiving praises and blessings from the wulin.
Since the series was first announced, it was wrapped up in various controversies. In particular, the casting of Michelle Chen attracted a large outcry by fans of the original novel, who called Chen the "fattest Xiaolongnü (little dragon lady)" that they have ever seen. When the show first premiered on Hunan TV, it was heavily panned for its bad writing, cheaply made actions scenes and a story that completely departs from the novel. Critics call the show "a vulgar mess possessing little artistic value", and "a production that completely destroyed the spirit of the original story".[2][3]
