Zhou Mo, a graduate student in the history department of a prestigious modern university, accidentally traveled through time and became a poor peasant boy in ancient times. Faced with the four walls of family disciples and clan oppression, the imperial examination was the only way to rise. Relying on his understanding of historical context, policy systems, and people's machinations, he integrated modern thinking with classic knowledge. Starting from an illiterate cowherd boy, he gradually broke through the difficult county and government examinations, and stepped into the turbulent Kyoto court. With a humble body, he stirred up the solidified chessboard of aristocratic families.
