During the Northern Dynasties, various forces were divided and the martial arts world was in turmoil. "Southern Blade" Li Zheng (played by Hu Bing) established the 48th Village in the Huxiang area, taking in the down-and-out martial arts people, and lived in seclusion from then on. But with the death of Li Zheng, the famous martial arts families also fell one after another. Many years later, Li Zheng's granddaughter Zhou Fei (played by Zhao Liying) was accidentally rescued by a young man who called himself Xie Yun (played by Wang Yibo) in Ximo River, and the two have been inseparable since then. Half a year later, Zhou Fei and Xie Yun met again in the black prison of Huojiabao, but were hunted down by several masters of the dark forces of the martial arts world "Disha Villa" at the same time, and the two were involved in a conspiracy catastrophe in the martial arts world. Zhou Fei was instructed by her predecessors in the martial arts world, and she kept honing her swordsmanship. She killed the evil spirits, quelled rebellions, captured the enemy king, and saved refugees with the courage of "the brave wins when they meet on a narrow road". Xie Yun accompanied Zhou Fei from beginning to end, giving her advice. The two of them worked together, never giving up, and together they quelled the turmoil in the martial arts world. The newcomers of the generation represented by Zhou Fei and Xie Yun have since grown into true "gentlemen with bandits", and Zhou Fei has finally become a generation of "Southern Sword" girl master.
