In 1162, aiming to expel invaders and recover the lost land to realize the reunification, Xin Qiji went to the south to persuade the Song Emperor to drive the Jurchens out of the north. Successfully accomplishing his mission, Xin Qiji only to find the commander Geng Jing was killed by a traitor and the army had lost morale.
