Wu Chengsi
Yet later that year, the chancellors Cen Changqian and Ge Fuyuan offended Wu Zetian by strenuously opposing the proposal to elevate her powerful nephew Wu Chengsi to be crown prince, and she had them arrested. Lai coerced Cen's son the county magistrate of Lingyuan into implicating another chancellor, Ouyang Tong, whom Lai subsequently arrested and tortured. However, he was unable to get Ouyang to admit to treason, and so he forged a confession from Ouyang. Cen, Ge, and Ouyang were all executed. Lai also killed the general Li Anjing ().
