Keyong sent Li Sizhao and an adoptive son, Li Cunshen, to attack Wang. Liu Rengong sent an army to aid Wang, forcing Li Sizhao and Li Cunshen to hold off on their attack and allowing Wang to take his army and flee to Liu. Even though Li Sizhao and Li Cunshen subsequently defeated another officer who rebelled against Li Keyong, Qibi Rang (), who then committed suicide, and retake Zhenwu (振武, in modern Hohhot, Inner Mongolia), which Qibi had seized, Li Keyong was still angry at them for allowing Wang to escape. He caned them and, for the time being, stripped them of their offices. In 906, Luo Shaowei, who distrusted the Weibo headquarters guards corps – as they had a history of assassinating or rebelling against past military governors – slaughtered the headquarters guards with support from Zhu. The other troops were outraged by this slaughter, and the officer Shi Renyu () rebelled and occupied Gaotang (高唐, in modern Liaocheng, Shandong), seeking aid from Li Keyong and Liu Shouwen.

Liu Rengong sought aid from Li Keyong to try to save Liu Shouwen. Under Li Keyong's demand, Liu Rengong sent troops to join Hedong forces under Li Sizhao and Zhou in attacking Lu Prefecture, to try to recapture Zhaoyi Circuit. When the joint Hedong/Lulong forces reached Lu Prefecture, Ding, who had been mourning Emperor Zhaozong (whom Zhu had assassinated in 905 and replaced with his son Emperor Ai), surrendered Lu to them. Li Keyong made Li Sizhao the acting military governor of Zhaoyi. However, a subsequent attack by Hedong forces on Ze Prefecture was unable to capture it, and therefore only Lu Prefecture was in Hedong hands by that point. In 907, Zhu forced Emperor Ai to yield the throne to him, ending Tang and starting a new Later Liang with him as its Emperor Taizu. Li Keyong, along with Li Maozhen (whose territory became Qi), Yang Wo the military governor of Huainan Circuit (淮南,
