Former Yan
Later in 369, after Murong Ping refused to cede the Luoyang region to Former Qin, as Former Yan had promised when seeking Former Qin's aid against Jin, Fu Jiān sent Wang to attack Former Yan. Wang requested that Murong Chui's heir apparent Murong Ling accompany him as a guide. After capturing Luoyang in early 370, Wang bribed Murong Chui's attendant Jin Xi (金熙) to give Murong Ling a false message that Murong Chui had heard that Empress Dowager Kezuhun had regretted her actions and that, therefore, he was defecting back to Former Yan. Murong Ling, unable to verify either the truth or the falsehood of the message, decided to defect back to Former Yan. Wang immediately accused Murong Ling of treason, and Murong Chui, in fear, fled, but was captured, although Fu Jiān believed that Murong Ling was acting independently and therefore pardoned Murong Chui. Former Yan did not trust Murong Ling and exiled him, and later that year, after he tried to start a rebellion, he was killed in battle after being betrayed by his brother Murong Lin.
