Su Yingwan unexpectedly wakes up and becomes the Queen Mother. Faced with the six-year-old little emperor Xiao Chengyan and the undercurrents in the palace, she abandons her harsh upbringing to reduce the little emperor's burden and rectify the hidden dangers around her. She brought Xiao Chengyan into contact with the School of Industry and Miscellaneous Studies, invited Shen Mo to teach practical knowledge, and also sold old items in the palace to subsidize the state treasury. During crises such as floods in the south and war in northern Xinjiang, Xiao Chengyan relied on what he had learned to calmly deal with the situation and gradually grew into a responsible monarch. Su Yingwan also firmly maintained the status and power of mother and son.
