I Rule the Borderlands as the Young Master

Modern man Li An transmigrates as the ninth prince of the Daqing Dynasty. To survive the ruthless struggle for the throne, he voluntarily requests an exile to the famine-ridden Southern Frontier, disguising himself as a debauched and tyrannical weak king. In the South, he secretly punishes corrupt officials, implements work-for-relief programs, and builds his power base. When the third prince Li Xu murders his father and frames Li An for regicide, Li An is forced to rise up and purge the rebellion. Leveraging modern knowledge to craft advanced weaponry and train an elite army, with the support of several beloved companions, he conquers treacherous passes, exposes the truth, quells the uprising, and successfully ascends to the throne.
