 Zhu escaped death only with help from Li Zhongchen, and Duan was killed.When Zhu then declared himself the emperor of Qin, he made Li Zhongchen one of his chancellors, and he kept Li Zhongchen in charge of Chang'an when he subsequently personally led troops to siege Fengtian.Li Zhongchen, however, was not able to deal with Tang resistance fighters near Chang'an, forcing Zhu to repeatedly send aid from Fengtian, hindering Zhu's efforts in sieging Fengtian.
