of four circuits—Xuanwu, Xuanyi, Tianping, and Huguo. Meanwhile, at Chang'an, the eunuchs, having established a firm alliance with Li Maozhen, were preparing to act against Cui. Cui, in fear, wrote to Zhu, claiming that the eunuchs were planning to attack Zhu in alliance with Li Maozhen. Zhu thereafter prepared to launch an army to march on Chang'an. When the eunuchs received this news, they seized Emperor Zhaozong and his family, and fled to Fengxiang with them. Campaign against Fengxiang Zhu Quanzhong subsequently reached Chang'an and rendezvoused with Cui Yin, and then proceeded to Fengxiang, where Li Maozhen and Han Quanhui had Emperor Zhaozong issue orders that he return to Xuanwu. After initial preliminary engagements there, Zhu turned around and focused his attention on first conquering Li Maozhen's other possessions in the Guanzhong region (i.e., the region around Chang'an) first, including, among others, Jingnan Circuit (靜難, headquartered in modern Xianyang, Shaanxi), governed by Li Maozhen's adoptive son Li Jihui; he quickly forced the surrender of Li Jihui and other subordinates of Li Maozhen, isolating Fengxiang. Han sent eunuch messengers to the circuits in the southeast, ordering them to attack Zhu's territory from behind, but most or all of them were intercepted and killed by Zhu's ally Feng Xingxi the military governor of Rongzhao Circuit (戎昭, headquartered in modern Ankang, Shaanxi).

Li Keyong tried to aid Li Maozhen by sending his nephew Li Sizhao and officer Zhou Dewei to attack parts of Huguo, but a subsequent counterattack by Zhu's nephew Zhu Youning () and officer Shi Shucong () beat back the Hedong forces and, for some time, actually put Taiyuan under siege again; while the Hedong forces subsequently repelled the Xuanwu forces, for several years thereafter, Li Keyong did not dare to again challenge Zhu Quanzhong's supremacy in the region. By summer 902, Zhu and his main army had returned to Fengxiang and put it under siege. Li Maozhen made several attempts to counterattack, but each of Li Maozhen's attempts was beaten back by the besieging Xuanwu army. (Meanwhile, Emperor
