In the first year of the Jingde era under Emperor Zhenzong of Song, the Liao dynasty used the Sixteen Prefectures of Yanyun as a base to launch a major invasion of Song. In the second year of Jingde, the two sides signed the Chanyuan Treaty.

"Sole ruler beneath heaven, the Ruyi Sword; wherever its edge points, all foes fall." Twenty years ago, Yin Qihua was peerless throughout the land with his Ruyi Sword, but was buried with it at the bottom of a cliff on Mount Hua. Twenty years later, the Ruyi Sword Manual has resurfaced. Does it truly contain the legendary treasure? Can the Ruyi Sword really make its wielder invincible and unite the realm?
Guo Ruhai, descendant of a military family, was one of the former Three Ruyi Swordsmen. His daughter, Guo Wanru, and Zhong Changgeng grew up together as fellow disciples.
