Oddly enough, Emperor Xuan believed that he could seize part of Northern Qi territory after Northern Zhou's victory, and he sent Wu Mingche to again advance north. In winter 577, Wu put Pengcheng (彭城, in modern Xuzhou, Jiangsu) under siege, and Emperor Xuan was confident that Wu would soon be able to capture the region south of the Yellow River. When the official Cai Jingli (蔡景歷) warned otherwise, he was so displeased that he demoted Cai to the post of a commandery governor. In spring 578, the Northern Zhou general Wang Gui (王軌) thoroughly crushed Wu, capturing him. Regretting his actions, Emperor Xuan recalled Cai to the capital. With the people's hearts shaken by the great defeat, in fall 578, Emperor Xuan held a ceremony in which the officials reaffirmed their loyalty to the state.
