During the Northern Song Dynasty, turmoil stirs in the north. The Jin kingdom eyes the Central Plains, while the Shadow Pavilion secretly colludes with foreign enemies and wreaks havoc across the martial world.
Overnight, young Shi Han loses his entire family. Rescued at the cost of his own life by the old man Mo Mei, he flees far beyond the northern frontier and vanishes for ten years.
To avenge his family's blood feud and protect the "Book of the Mountains and Rivers," a treasure vital to the Song Empire's survival, he heads south alone and becomes a disciple of Yue Linfeng of the Qingfeng Sword Sect.
By chance, Shi Han learns the long-lost Cold River Sword Style in a cave on Sunset Isle. His inner power surges, and his martial arts improve by leaps and bounds.
Along the way, he meets Huang Lingshuang, a chivalrous woman from Mount Huang. Together they face life and death, and feelings quietly blossom between them.
Through the storms of Jiangnan, adventures at the heart of a lake, martial arts tournaments, and bloody battles on the frontier, he grows from an inexperienced boy into a chivalrous swordsman with peerless skills.
Atop Mount Jun, Shi Han defeats the entire Shadow Pavilion with a single sword strike, shakes the world, and earns the unanimous respect of the martial world as its leader.
He then leads righteous fighters north to Yanmen Pass to repel the Jin invaders and keep the border secure.
In the end, he eradicates evil and restores peace to the land. Having fulfilled his mission, he retires with the woman he loves to a quiet life among the green hills.
He carries the spirit of chivalry, and with his sword he defends the mountains and rivers.
A tale of a young man's growth, martial-world feuds, duty to country and family, and romance.
