In the final years of the Great Zhou Dynasty, the court is corrupt and the martial world is in turmoil. War rages along the northern border, while undercurrents stir in the south, where a plot involving the former dynasty’s hidden treasure is taking shape. Li Ran, a gifted swordswoman born into poverty, is caught up in a vortex of political intrigue and martial-world vendettas after an accident. The choices she makes will affect the fate of the entire dynasty. While investigating her master’s death, Li Ran unexpectedly obtains half of the Riverlands Token, said to be the key to unlocking the former dynasty’s hidden treasure. Forces from the imperial court and the martial world spring into action, and she gradually discovers that her own origins are closely tied to the conflict. Xiao Yunlan is ordered to seize the Riverlands Token, but his resolve begins to falter as he clashes with her. Meanwhile, Xue Wulei plots in secret, hoping to use the treasure’s power to overthrow the dynasty. Seeking the truth, Li Ran ventures alone into the Listening Rain Pavilion in Jiangnan, where she is besieged by martial-world experts. Xiao Yunlan comes to her aid, and the two are forced to join forces, gradually falling for each other as they work together. But when Li Ran discovers Xiao Yunlan’s true identity, her trust collapses in an instant. Xue Wulei takes the opportunity to appear, revealing that she is the last surviving descendant of the former dynasty’s imperial family and goading her to unleash a bloodbath in the name of revenge. Caught in an agonizing choice, should she obey the demands of her bloodline or stay true to herself?
As the hidden treasure in the imperial tomb is unlocked, Li Ran and Xiao Yunlan cross swords. At the critical moment, she shatters the Riverlands Token, foiling Xue Wulei’s scheme. But this also makes her a wanted criminal in the eyes of the court, with nowhere left to hide in the martial world. Some say they once saw a lone figure walking through the snow, sword flashing like frost; others say a white-clad general appeared amid the beacon fires beyond the frontier. The land remains as it was, but no one knows whether the legend of the Green Frost Sword is true.
