Han Lin transmigrates into the body of the Emperor of Qi and becomes bound to a Tyrant System, which forces him to indulge in beautiful women and extravagant construction projects every day, behaving like the foolish and debauched ruler in everyone's eyes. But no one knows that he is secretly using the system's missions to put his plans into action, reform corrupt officials, train troops, and expand his territory. Though he appears immoral and incompetent, he is actually carefully plotting to make his kingdom powerful. As Qi grows increasingly prosperous, its territory expands, and the imperial court remains stable, with beautiful women filling the imperial harem, everyone wonders how this supposedly foolish emperor keeps making his kingdom stronger.
