Baili Jing, the third prince of the Great Jin Dynasty, was originally an ordinary prince who barely attracted any attention. One day, he was suddenly appointed to Youzhou, a barren land on the northern frontier. Thinking he had merely been exiled to guard the border, he unexpectedly became bound to a City Lord System, tying his fate to that of Youzhou. Faced with dilapidated cities, rampant bandits, and other problems, the inexperienced Baili Jing must grow from an overlooked prince into a border lord capable of standing on his own.
