This story is about a young Daoist disciple, Geng YuJing, who travels from Wudang Mountain on a journey of self-discovery across China. It is based on a novel of the same name (Wu Dang Yi Jian) by Liang Yusheng.

During the late Ming dynasty, a time when the nation faced enemies externally and within, the young hero Geng Yu Jing discovered that his birth parents' death was due to a conspiracy that snared the pugilist world. As he embarked on a journey of self-discovery traveling back to his birthplace at Northeast frontiers of China, he uncovered dark secrets of the past, found warm friendship, and romance but also sorrow and enmity. These adventures eventually shaped him to became the legend known as the "First Sword of Wudang".—Unknown
