Three years ago, the "Sword Immortal" Ye Guzhou disappeared mysteriously, and there were rumors that he had been poisoned by his enemies. His close disciple Shen Jinghong, carrying a mysterious invitation written in a familiar handwriting, chased him from the north of the Great Wall to the south of the Yangtze River. The iron sword wrapped in old cloth at his waist hid the secret of the lost secret technique "Three Styles of Liuyun". The pursuer follows him like a shadow. The "Shadow Pavilion" killer under the bronze mask always reveals his poison-quenched short blade on moonlit nights, just to snatch the "Liu Yun Sword Manual" that is said to dominate the martial arts world.
An accident on the banks of the Xunyang River caused Shen Jinghong to bump into Su Ningshuang, who was rushing to Lushan to discuss swordsmanship. This girl who carries family secrets has clear eyes when her skirt is stained with wine, and she is deep in thought when holding the detoxification pill between her fingertips - her enemy is the Celestial Canker Sect that has annexed the seven sects and practices evil arts, and the Shadow Pavilion is its minion.
The two swords clashed for the first time in the cold night, and they were destined to end up in a confusing situation together. Deep in the clouds and mists of Lushan Mountain, are there traces of Master Shen Jinghong, or is it a trap set by the Tiancan Cult? When Liuyun swordsmanship meets Shuangying Qinggong, when the wandering swordsman meets the revengeful girl, what they want to uncover is not only the martial arts conspiracy, but also each other's fate hidden between sword moves and heartbeats.
