Zhang Gongduo and Hou Hongshi (), and then died. The news of his death was not immediately announced, and Wang informed Zhao Jiliang first. As he did, he was weeping, and Zhao Jiliang pointed out that the state was not yet on firm grounds, and that the appropriate thing to do is to quickly support Meng Chang to take the throne. Wang apologized and agreed. Zhao then instructed him to inform Li and to observe Li's attitude (as both of them had suspicions that Li might be unwilling to serve a young emperor). When Wang reached Li's mansion, however, Li only met him after surrounding himself with armed guards. Wang therefore decided not to inform him of Meng Zhixiang's death, until after Meng Chang took the throne shortly after. (With Zhang and Meng Chang's close associates Han Jixun (), Han Baozhen (), and An Siqian () all suspecting Li as well, Meng Chang shortly after had Li arrested and put to death after consulting with Zhao Jiliang and Zhao Tingyin; Wang's involvement in the matter, if any, was not stated in history.) Meng bestowed on Wang the honorary chancellor title of Shizhong () and also gave him the title of military governor of Wutai Circuit (武泰, headquartered in modern Chongqing). (As with the case with other high-level Later Shu officials/generals at the time, Wang did not actually report to Wutai, but governed the circuit remotely through staff members.) In 938, Wang, who was still serving as chief of staff and continued to do so, was made the military governor of Wuxin Circuit (武信, headquartered in modern Suining, Sichuan), and given the honorary chancellor title of Tong Zhongshu Menxia Pingzhangshi (). In 941, Meng Chang, believing that the circuits were being misgoverned in the absence of the high level officials who were also serving as their military governors, bestowed additional honorific titles on Zhao Tingyin, Wang, and Zhang, but stripped them of their military governor titles and put those circuits under civilian officials. However, in 944, for reasons unclear, Meng reversed his reforms on this issue, and Wang was given the military governorship of Baoning Circuit (保寧, headquartered in modern Nanchong, Sichuan). It was said that because of his accomplishments and seniority, Wang became very autocratic and corrupt, widely selling offices for bribes. His son Wang Dejun () was similarly corrupt. In 948, after senior chancellor Zhang Ye was put to
