The Legend of the Freeman

When the new emperor ascended the throne, in order to maintain his power, he demoted many civil servants and generals to an empty border town. As a result, he became the king of the country, and when he led the defeated soldiers to the border town, everything surprised him. The white-haired civil servants and generals had all turned into handsome young men, and the deserted border town was now indeed prosperous. But what puzzled him even more was why his father, who had died many years ago, was there.
