Xiao Beixuan, heir to Nanzhao, returns after three years of travel. He seems carefree and irreverent, but is in truth a shrewd schemer.
On the orders of his father, Xiao Han, he is to marry Qingluo. But he secretly makes his own arrangements, exploiting Chen Qingzhi's feelings for Xu Weixiong to send him to Western Shu. At the same time, he orders Chu Lushan to secretly contact Nanzhao's former forces, preparing to take charge of Nanzhao in the future.
Xiao Beixuan is ambushed by Zhao Xun in the reed marshes. With the help of Sword God Li Chunfeng, he survives and becomes his disciple, learning the Twin Sleeves Green Snake technique and greatly increasing his strength.
Later, Xiao Beixuan forces his way into the Qintian Observatory to get justice for Old Ye. He also practices martial arts with Nangong Wenya at Tingchao Pavilion, and the two develop feelings for each other. After Xiao Han dies of illness, Xiao Beixuan officially succeeds him as King of Nanzhao. Facing the enormous pressure of Beiman's invasion, he puts Xu Beizhi and Chen Xiliang in important positions, reorganizes the military, and lays out a strategy. In the Battle of Liang and Mang, he overcomes the odds and ultimately drives back Beiman, protecting Nanzhao.
However, Xiao Beixuan knows that the Liyang court distrusts Nanzhao, while various forces in the martial world are watching hungrily. Greater challenges lie ahead.
In the end, Xiao Beixuan gives up his position as King of Nanzhao and retreats from the world with Qingluo, Nangong Wenya, and the others, living a carefree life.
