In 393, Murong Chui, under advice of his brother Murong De, decided to attack Murong Yong to end any doubt about the Yan succession. In early 394, he got his forces ready in battle posture, but did not attack for several months. Murong Yong thought Murong Chui was trying for a trick attack and tried to anticipate it, but Murong Chui then attacked by three different routes, leading the main army heading for Zhangzi. Murong Yong personally engaged Murong Chui but was defeated, and he fled back to Zhangzi to try to defend the city. He also sought emergency aid from Jin and Northern Wei, but before Jin and Northern Wei forces could arrive, Zhangzi fell, and Murong Chui captured and executed Murong Yong. Western Yan was at its end, and its territory was annexed to Later Yan.
