Li's assassins then suggested the next move — assassinate the chancellor Wu Yuanheng, whom Emperor Xianzong had put in charge of the logistics of the operations against Zhangyi. Li agreed, and sent them with sufficient funds to the capital Chang'an to carry out the operation. Shortly after, Wu Yuanheng was assassinated, and the assassins also attacked another official in favor of the campaign against Wu Yuanji, Pei Du, but failed to kill Pei. Suspicions quickly fell on soldiers that Wang had sent to Chang'an as liaisons — as Wang had, shortly before, submitted a petition that attacked Wu Yuanheng bitterly. Wang's liaisons were arrested and, probably under torture, confessed to assassinating Wu Yuanheng. Emperor Xianzong thus declared Wang a renegade, while, at that point, not suspecting Li, and his assassins were able to flee Chang'an without being arrested. When some officials suggested ending the campaign against Zhangyi, Emperor Xianzong firmly refused, and further made Pei chancellor.
