In the turbulent land of China during the Kangxi period, Lu Chenzhou, a former commander of the Jinyi Guards of the Ming Dynasty, robbed the Qing court of military pay and beheaded the third-rank assistant leader, which attracted a crazy pursuit of twelve golden orders. The "Thirteen Iron-Blooded Riders" suffered heavy casualties in order to protect them from breaking through. Lu Chenzhou was seriously injured, and with the "Secret Pact against the Qing Dynasty" in his arms, he went through hardships and fled to the fishing village of Lujiang River, where he transformed into a fisherman on the river.
Life in the fishing village seems peaceful, but there is an undercurrent. Lu Chenzhou behaves like a fisherman every day, obsessed with wild grass and alchemy, but his hidden martial arts and mysterious past still attract the curiosity of village girl Liu Ruyan and mute boy A Zhu. However, the secret agents of the Qing court followed him like a shadow, and the blood-thirsty Li Sanguai and others were in hot pursuit. The forces in the world also had their own hidden agendas and kept testing. Lu Chenzhou was struggling to wander on the edge between concealment and visibility. While guarding the secret agreement, he had to deal with crises from all sides, and he also had to make painful choices between his personal emotions and his responsibilities to his family and country.
Can he, in this crisis-ridden environment, rely on wisdom and courage to break through the siege and realize his ambition to defeat the Qing Dynasty and restore the Ming Dynasty? On the banks of the Lujiang River, a thrilling historical legend is slowly beginning.
