Beginning Sesame Official: from County Magistrate to Emperor

He traveled through time and became the son of a dignified Duke, but at the beginning he was demoted to the border as a county magistrate. Then just lie down and be a local emperor who waits for death and watches beautiful women dancing every day. What? The emperor asked me to be a teacher? What? The princess cried and wanted to marry me after reading my poem? What? Will neighboring countries surrender when they hear my name? What? The northern aliens knelt down when they saw me? Crazy? I'm just a county magistrate!
