Li Chengyun promised Yu Jingrong that he could spare Yu Qingmei, but he banished Yu Qingmei from Q City and forbade her from ever setting foot there again.
Of course, merely expelling her from Q City wasn't enough to set Li Chengyun's mind at ease—especially knowing that she was mentally unstable. Who knew whether she would cause more trouble?
Yu Qingmei's actions paid no heed to social morals and laws. She was clearly the type who would stop at nothing to hurt others. If she was mentally ill, she should be treated properly. So, while banishing her from Q City, Li Chengyun also sent her to a mental hospital in the nearby R City, where she was placed under strict control.
Having settled matters with Yu Qingmei, Yu Jingrong found Mo Liusha to thank her specifically.
