Meanwhile, Lu Yanhong, after Yang Fuguang's death in 883, had taken his troops and become a roving marauder, raiding through Shannan East (山南東道, headquartered in modern Xiangfan, Hubei) and Shannan West (山南西道, headquartered in modern Hanzhong, Shaanxi) Circuits, despite the imperial government's attempt to appease him by making him the acting military governor of Shannan West. In fall 884, Lu advanced east and rendezvoused with two officers under Qin Zongquan (who had himself become a renegade to Tang by that point), Qin Gao () and Zhao Deyin, to siege Shannan East's capital Xiang Prefecture (). After capturing Xiang Prefecture, Lu raided parts of Wuchang (武昌, headquartered in modern Wuhan, Hubei) and Huainan (淮南, headquartered in modern Yangzhou, Jiangsu) Circuits and then headed for Xu Prefecture. Hearing of Lu's impending attack, Zhou Ji abandoned Zhongwu and fled. Lu took over Xu Prefecture and claimed the title of acting military governor; the imperial government, unable to stop him, subsequently commissioned him military governor. That was the last historical reference to Zhou, and it is not completely known what happened to him afterwards — although both the chronicles of Emperor Xizong's reign in the "Old Book of Tang" and the "New Book of Tang" indicated that Lu killed him.
