As he barely escaped death and returned to the palace, the cunning and power-thirsty Prince Yun questioned his defeat, forcing Pei Yanzhi to relinquish control of the military. Realizing that Prince Yun was coveting the imperial power in the act of supporting the enthroning of the young emperor, Prince Qi came to a tacit agreement with the young emperor and decided to withdraw himself from courtly affairs.
