王延政
In response, Wang Xi sent his generals Pan Shikui () and Wu Xingzhen () to attack Wang Yanzheng with 40,000 men. Wang Yanzheng sought aid from Qian Yuanguan, the king of Min's northern neighbor Wuyue. Qian sent the general Yang Renquan with 40,000 men to aid Wang Yanzheng. Before Yang could arrive, though, Wang Yanzheng had already defeated the Min central government army, killing Pan and forcing Wu to flee. Wang Yanzheng also used the opportunity to also capture the cities of Yongping () and Shunchang () (both in modern Nanping). When Yang's army arrived, Wang Yanzheng tried to send him away by offering beef and wine to the troops, but Yang refused, instead setting his camp outside the city, posturing to get ready to besiege it. In fear, Wang Yanzheng wrote Wang Xi, requesting aid. Wang Xi sent their nephew Wang Jiye () with an army to aid him, and also wrote Qian to rebuke him and sent another army to cut off the Wuyue army's food supply route. Once the Wuyue army's food supply ran out, Wang Yanzheng attacked, defeating it. Yang then withdrew. Subsequently, Li Jing, the emperor of Min's northwestern neighbor Southern Tang, sent the emissary Shang Quangong () to both Wang Xi and Wang Yanzheng, urging them to make peace with each other. With Li Jing's moderation, Wang Yanzheng sent officers and female servants to submit a statement of oath and an incense censer to Wang Xi. Subsequently, Wang Yanzheng's emissaries and Wang Xi swore an oath at their father Wang Shenzhi's tomb. However, despite this oath, the suspicions between the brothers remained.
