Chu Xiao unexpectedly travels through time and becomes the neglected Ninth Prince of the Great Xia Dynasty. His predecessor was timid and insecure, struggling to survive in the depths of the imperial palace. But Chu Xiao remains true to himself, seeking nothing more than a peaceful life while waiting to come of age, receive his princely title, and move to his fiefdom to enjoy a carefree existence. When the Imperial Household Department cuts his monthly allowances, a favored consort abuses her influence to make things difficult for him, and the Crown Prince schemes to frame him and ruin his reputation, Chu Xiao remains composed and unyielding. With extraordinary courage and quick wit, he repeatedly overcomes these crises, fiercely protecting the maid who treats him sincerely and Consort De. He also puts modern knowledge to practical use, improving printing techniques to spread classical texts and benefit students from humble backgrounds.
