Jing Ke
In the film, Ying Zheng sends his concubine Lady Zhao to the Yan state as a spy to enlist a Yan assassin to attempt to assassinate him, intending to use that as a "casus belli" to start a war against Yan. Lady Zhao persuades Jing Ke to perform the assassination. After learning of Ying Zheng's massacre of the children in her home state of Zhao, Lady Zhao desires the assassination in earnest. The attempt fails, but Ying Zheng expresses his fury when his associates make no attempt to stop the assassin and he is forced to kill Jing Ke himself. He is further saddened when Lady Zhao returns to Qin only to retrieve Jing Ke for burial.
