put him under house arrest. By 939, Wang Jipeng had alienated two elite corps that his father Wang Yanjun established, the Gongchen () and the Anhe (), by establishing his own elite corps, the Chenwei (). The commanders of the Gongchen and Anhe corps, Zhu Wenjin and Lian Chongyu, feared death, and therefore decided to mutiny. They rose and defeated Wang Jipeng's Chenwei corps, and then went to Wang Yanxi's mansion, offering the throne to him. Wang Jipeng fled, but was later captured and executed. Wang Yanxi took the throne. Reign As King of Min While Wang Yanxi took on much of the imperial trappings—including commissioning officials for his imperial administration, issuing a general pardon, and changing era name—he nevertheless only assumed the title of King of Min at the moment and submitted a petition to Shi Jingtang, the emperor of Later Jin, which then controlled the Central Plains, to be Later Jin's vassal. He changed his name to Wang Xi. Publicly, in announcing Wang Jipeng's death, he blamed it on a mutiny by the Chenwei Corps. He commissioned (presumably by this point) his father-in-law Li Zhen as chancellor. A number of sorcerers who had misled Wang Jipeng were executed. However, Wang Xi, once his power was affirmed, turned out to be arrogant, licentious, and cruel, and he was suspicious of other members of the Wang imperial clan. His younger brother Wang Yanzheng the prefect of Jian Prefecture (建州, in modern Nanping, Fujian) often wrote him to try to correct his behavior, but that led him to be angry. He sent his close associates Ye Qiao () to serve as monitor of Wang Yanzheng's army, and Du Hanchong () to serve as monitor of the army at Nanzhen Base (南鎮軍, near Jian). Both Ye and Du frequently submitted reports of their suspicions about Wang Yanzheng, adding to the friction. In 940, after an argument between Wang Yanzheng and Ye, Wang Yanzheng tried to arrest Ye, but Ye was able to flee. Wang Yanzheng then rose in full rebellion against Wang Xi's administration, and he quickly defeated the imperial generals in Jian's vicinity. When Wang Xi then sent the generals Pan Shikui () and Wu Xingzhen () to attack Jian, Wang Yanzheng sought aid from Min's northern neighbor Wuyue. Wuyue's king Qian Yuanguan sent a detachment commanded by Yang Renquan and Xue Wanzhong () to aid Wang Yanzheng, but Wang Yanzheng
