Waking up, An Zizai transmigrated to become the Ninth Prince of Great Chu, yet became a "useless prince" mocked by everyone. Unlearned and unskilled, incompetent in martial arts, he even slept publicly during the court policy essay discussion. Facing the Emperor's questioning, a seemingly absurd answer shocked the entire court, and also activated a mysterious system for him. After a ten-consecutive draw, heaven-defying fortune descended, and his hidden strength quietly awakened. While others were busy contending for the throne, An Zizai only wanted to bask in the sun and enjoy life. Yet as a bowl of mysterious delicacy and a cup of ordinary spring water triggered a commotion in the capital, everyone began to discover—this seemingly laid-back ninth prince was perhaps far less simple than he appeared on the surface.
