At this time, the magician Guo Nen (), whom Lü Guang and his people had trusted greatly, prophesied that Later Liang was about to be destroyed, and therefore started a rebellion himself within the capital Guzang, capturing even Lü Guang's eight grandsons and executing them cruelly. Guo soon supported the general Yang Gui () as the leader of the rebellion. Lü Zuan was forced to abandon his attack against Duan and return to Guzang. Eventually, however, Yang and Guo were defeated by Later Liang forces and forced to flee to and submit to Southern Liang and Western Qin, respectively. From this point on, however, Later Liang, by now highly reduced in size and strength, were subject to constant attacks by Southern Liang, Northern Liang, and Western Qin, causing it to be unable to hold its territory. By 398, the western parts of the Later Liang (including Xiyu holdings) had fallen to Northern Liang as well. In 399, Lü Shao and Lü Zuan launched another attack on Northern Liang, but with Southern Liang coming to Northern Liang's aid, they were forced to withdraw.
