— was about to occur. Li, believing that Wang would be a general who can serve in the campaign, thus kept him as an imperial guard general at Luoyang. Shortly after, when Meng and Dong did openly rebel against the imperial government, Li put his son-in-law Shi Jingtang in command of an army against the two circuits and made Wang the forward commander for Shi. He also made Wang the defender of Chang'an. During the campaign against Xichuan and Dongchuan, it was Wang, along with other generals Wang Hongzhi (), Feng Hui (), and Zhao Zaili (), who made a daring surprise attack against the key pass Jianmen Pass, surprising the Dongchuan garrison at Jianmen and allowing the imperial army to take Jianmen, for one time causing Meng to panic and believe that all was lost. However, as the rest of the imperial army could not follow up and meet up with them at Jianmen, they eventually had to abandon Jianmen and rejoin the rest of the imperial army, which subsequently became caught in a stalemate with the Xichuan/Dongchuan armies and was forced to withdraw. After the imperial army's withdrawal, Wang Sitong, for his accomplishments, was made the military governor of Shannan West Circuit (山南西道, headquartered in modern Hanzhong, Shaanxi).

Meng desired peace with the imperial government, but Dong, because the imperial government had executed his son Dong Guangye () and Dong Guangye's family, rejected it, and further renounced his alliance with Meng and attacked Meng. Wang notified the imperial government of this, Li's new chief of staff Fan Yanguang suggested to him that this was the time to act against the two circuits while they were fighting with each other, so Li ordered Wang to begin planning for such a campaign. However, shortly after, Meng defeated Dong, who was then killed by his subordinates, and Meng took over Dong's realm. The imperial government thereafter abandoned further designs on the two circuits, as Meng nominally resubmitted to the imperial government as a vassal. Wang was thereafter returned to Chang'an to serve as its defender. During Li Conghou's reign Li Siyuan died in late 933 and was succeeded by his biological son Li Conghou the Prince of
