Jing Ke
King Zheng and his troops continued to take over different states. The state of Yan was small, weak and frequently harassed by soldiers. It was no match for the Qin state. So Crown Prince Dan of Yan plotted an assassination attempt to get rid of King Zheng, begging Jing Ke to go on the mission in 227 BC. Jing Ke was accompanied by Qin Wuyang in the plot. Each was supposed to present a gift to King Zheng: a map of Dukang and the severed head of Fan Wuji.
