With the addition of fifty thousand Anyang Army troops and no assassination or disruption, the disaster relief in Fengcheng and Yuqiu went very smoothly and swiftly.
Qing Po, disguised as Su Zizhan, issued a warrant to arrest officials who fled from both Fengcheng and Yuqiu. He quickly apprehended officials who had neglected their duties and escaped to avoid trouble after the disaster, executing them publicly by beheading.
At the same time, he dismissed all officials of government offices within a hundred miles, including the Prefect and County Magistrates, placing them in the Heavenly Prison to await judgment.
Within a mere three days, the area encompassing a hundred miles around Fengcheng, Yuqiu, and the Heilong River had undergone complete transformation.
