The evil king Shi Zhixuan's martial arts are world-famous, but he is afraid that his evil martial arts will cause disaster to the world in the future, so he freezes himself and the evil emperor relics who have sealed their huge skills in the evil king's tomb. The only key to enter the tomb of the evil king is the secret book "Secret of Eternal Life", which records the best martial arts, so everyone in the rivers and lakes wants to get it, but it has been lost in the rivers and lakes for many years, and no one knows where it goes. On the other hand, although Kou Zhong (played by Lin Feng) and Xu Ziling (played by Wu Zhuoxi), two orphans in Yangzhou City who have been dependent on each other since childhood, have been doing some petty theft to make a living, they are both talented and hope to learn a good martial arts in the future, so they want to worship the local Shilong Taoist as a teacher. Unexpectedly, when I went to look for Shi Long, I found that Shi Long was fighting with a woman with strong martial arts, Fu Junwu. It turned out that Shi Long stole the "Recipe for Eternal Life" from Fu Junwu, which everyone on the rivers and lakes wanted. After a vicious fight, Fu Junwu retrieved the "Secret of Eternal Life", but was also seriously injured, and Kou Zhong and Xu Ziling fled with her. At this time, the Imperial Guard's Janissaries totaled Yu Wenhua and led a group of people to rob the "Recipe of Eternal Life", Fu Junwu knew that the three of them would definitely not be able to run away if they left together, so she handed over the "Recipe of Eternal Life" to Kou Zhong and the others for safekeeping, and then she led away the pursuers alone. Kou Zhong and Xu Ziling, the self-proclaimed Yangzhou Shuanglong, began their journey to the rivers and lakes.
