After Being Replaced by a Civet Cat as a Prince, I Want to Travel Around the World

After three years as prince, three years as prince, and four years as emperor, I was finally old enough to govern myself. However, the Queen Mother, who was in charge of the government from behind the curtain, thought I was difficult to control and had my diploma replaced by someone else's. Damn it, old godmother, I'm giving you face, right? If the tiger doesn't show its power, you really think that I am a puppet emperor!
