Meanwhile, by 815, Emperor Xianzong's forces were deeply entrenched in a campaign against another ally of Wang Chengzong's, Wu Yuanji, who ruled Zhangyi Circuit (彰義, headquartered in modern Zhumadian, Henan).
Shortly after, Wu Yuanheng was assassinated - probably by assassins sent by Li - and another official who advocated for the campaign against Wu Yuanji, Pei Du, was nearly also killed.
