"Xuanjing Cold Blade" tells the story of Ye Xuan, a young man from the border area, and Su Qinghan, a chivalrous girl from Jiangnan, who were involved in a dispute between Jianghu and Jianghu due to two peerless secret books.
Ye Xuan was originally an unknown traveler driving a mule cart. He carried the "Tianyan Jue" left by his master with him and lived a life without competing with the world. In an accident, he saw the killer of Broken Soul Valley chasing Su Qinghan, who was carrying a copy of the "Marrow Cleansing Sutra". He became chivalrous and rescued him, but he didn't know that this rescue would completely push him into the whirlpool of the world.
Su Qinghan is an orphan of the Su family in Jiangnan. Her father was brutally murdered by Soul-Desolating Valley because of the "Marrow Cleansing Sutra". She fled to the world with a copy, but she was poisoned by the other party's Seven-Star Begonia, and her life was hanging by a thread. Ye Xuan's appearance became a glimmer of light in her desperate situation, and Ye Xuan's seemingly basic but hidden martial arts also made her suspicious.
One is a young man who ignorantly enters the world with mysterious martial arts knowledge, and the other is a chivalrous woman who is burdened with a blood feud and is poisoned. The two are forced to go together. They not only have to avoid the crazy pursuit in Broken Soul Valley and find the Ice Silkworm Snow Lotus that can detoxify the seven-star begonia, but they also have to deal with the coveting of the two secret books by all the forces in the world.
Ye Xuan gradually uncovered the secrets of the "Tianyan Jue" in life-and-death battles, and also understood the deep meaning of his master's "Don't use this technique unless necessary"; Su Qinghan saw hope other than revenge in getting along with Ye Xuan, but he was also caught in a dilemma due to family grudges and the morality of the world.
When the secrets of "Tianyan Jue" and "Marrow Cleansing Sutra" gradually come to light, and when personal destiny is closely connected with the safety of the world, can Ye Xuan and Su Qinghan keep their original aspirations amidst the swords and swords, and find their own destiny amidst the grievances and hatreds?
