The Three-and-a-Half-Year-Old Crown Prince Helps His Father Conquer the Realm

(Beloved by everyone + feel-good power fantasy + unreliable emperor dad + unreliable empress mom + heroine disguised as a boy + clueless System) The emperor ran off with his empress, leaving behind their three-year-old crown prince. To keep the child from disrupting their time together, they simply dumped him on the ministers! The little crown prince attending court? Who says children don’t know any better? Everyone, get out of my way! Which country’s ministers need on-the-job training? Which country’s ministers have to learn their multiplication tables? And take an annual exam, too? Ugh, the ministers are weeping, but their efficiency is truly incredible! What do they do when they start getting hooked on math problems? A group of ministers looked helplessly at the three-year-old sitting on the throne and discussed it together: Let’s have the crown prince stage a coup! He can just become emperor. Then the unreliable, incompetent ruler can go wherever he likes! We’re done dealing with him. But the ministers’ worst ordeal was yet to come! They actually had to follow the crown prince to aid another post-apocalyptic world. What were they supposed to do? That monster was terrifying!! Your Highness, this old minister just can’t do it!!
