After General Xiao Jue pacified the northern border, Emperor Li Shen was afraid that he would disband his armor and return to his fields. He lived in seclusion in Yunmengze and devoted himself to farming. However, Li Shen captured the old troops and made random changes to the defenses, causing chaos in the north, and the barbarian iron cavalry would move south. At the critical moment, Li Shen issued an imperial edict and begged Xiao Jue to come back. Xiao Jue gathered his old troops together and relied on his wisdom to defeat the enemy's army and stabilize the northern border. After his success, he refused the reward and returned to Yunmengze, continuing to protect his farmland and peace.
