In 776, after the death of Tian Shenyu (田神玉, Tian Shen'gong's brother), the acting military governor of Biansong Circuit (汴宋, headquartered in modern Kaifeng, Henan), Tian Shenyu's subordinate Li Lingyao () seized control of Biansong Circuit and tried to act independently as well. This time Emperor Daizong reacted by ordering Li Zhengji, Li Zhongchen, Li Mian, Ma Sui, and Chen Shaoyou () to attack Li Lingyao. The main attack against Biansong's capital prefecture Bian Prefecture () was commanded by Li Zhongchen and Ma, but the other military governors also attacked Biansong from other sides, and, as part of the campaign, Li Zhengji seized five of the eight Biansong prefectures and requested that they be merged into Pinglu. Emperor Daizong agreed, and Li Zhengji moved his headquarters from Qing Prefecture () to Yun Prefecture (鄆州, in modern Tai'an, Shandong), leaving Qing Prefecture in Li Na's hands. Also at his request, Emperor Daizong incorporated Li Zhengji's line into the imperial clan rolls. It was said that by this point, Li Zhengji became the most powerful military governor, with 100,000 men in his army. He governed Pinglu with a harsh hand, such that the citizens in Pinglu did not dare to converse with each other publicly, but it was also said that his laws were fair and simple and the tax burden was low. The military governors of the nearby circuits were all fearful of him. Emperor Daizong created him the Prince of Raoyang.
