The Battle of the Qiu River

The Fang clan and the Yun clan are fighting for the control of the Qiu River. Yun Dahao worried his son, Yun Hanzhang, may be too lenient, so he makes Hanzhang swear upon death penalty that he will uphold his mission. He also sends his daughter, Yun Jinshang, to be the vanguard. At the battlefield, Jinshang is captured by Cheng Beihai and Fang Ziyan is also defeated by Hanzhang, but he released her. Ziyan pleads with Beihai to stop fighting but in vain. So she helps Hanzhang sneaks to the Fang’s camp to rescue his sister but failed. Ziyan then persuades her father Wancheng to make peace and he consents to let her be the peace envoy. At the enemy's camp, she sees that Hanzhang is awaiting execution and she pleads with Dahao to pardon Hanzhang. Dahao agrees to meet Wancheng by the riverbank but it turns out to be a trap. Hanzhang leads his forces to protect Dahao and they fight with Beihai. Ziyan sends someone to sink the battleships and Beihai is defeated. Finally, Dahao and Wancheng agree to make peace with each other.
