In 921, Wang Rong was assassinated by his adoptive son Wang Deming, who took over the Zhao realms, changed his name back to the original name of Zhang Wenli, and slaughtered the Wang clan. Li Cunxu subsequently prepared for a campaign against Zhang Wenli (who soon died and was succeeded by his son Zhang Chujin). As part of his preparation, he had Li Cunshen and Li Siyuan stationed at Desheng (德勝, in modern Puyang, Henan) and Qicheng (戚城, in modern Puyang as well) respectively and then pretended to withdraw to lure Later Liang forces under Dai. When Dai attacked, Li Cunxu himself (along with Li Siyuan and Li Cunshen) defeated him. This victory allowed Li Cunxu himself to leave the front and go to the Zhao front himself. In 922, Dai, hearing that Li Cunxu had left to siege Zhao's capital Zhen Prefecture (), launched another major attack on Desheng. Li Cunshen defended the city, and Dai was unable to capture it. Li Cunxu subsequently came to his aid, and Dai withdrew.
