Zheng Yihua, the self-made female chairman, made a bet with her competitors to test a new game product "Sanding". An imaginary game world with the basic background of the late Eastern Han Dynasty. She will play the role of Liu Yu, the prince of Yanbei, who disguises himself as a man (the game is set in the fictional setting), who will unify the fragmented land of China within 45 years and establish a new Northern Han Dynasty. After this challenge, Zheng Yihua can truly understand how to balance emotion and power, understand the meaning of life and governance, and regain his original intention of serving the country and the people amidst the struggle of swords and intrigues.
