Chapter 522 - Ministry of Control and Punishment
Regardless of whether the people there wanted to investigate, the amount of clues that could be found in the cell was always limited. Liu Chong had only fallen to the crime of not being strict with regulations, and got paid with his salary for half a year's worth of work, in the eyes of Tianhui Emperor, the lives of the prisoners and servants were worthless. To be able to kill Yun Qianliang in an accident, the rest of the innocent lives were nothing to him.
However, the Gu Xiangfu and the Jin Mansion had been sending people to investigate the entire time. Even the cells where the male prisoners were held were investigated once, asking if they heard any strange noises that night.
