Thirty miles north of the Imperial City lay the continuous Northern Min Mountains, with their over one hundred and sixty peaks towering high. Unlike the mountains in other parts of Nanzheng State, the peaks of the Northern Min Mountains were extremely high, successfully blocking the invasion of the Northern Barbarians and keeping the Capital of Nanzheng safe like a fortified citadel for nearly a hundred years.
Thus, even though the Nanzheng State had decayed to the point of stench, it had enjoyed several eras of peace. Moreover, Nanzheng State bordered the sea to the east, and Nanyu had only a few small countries to its south, while to the southwest and west, the three large nations comparable in strength to Nanzheng State were in a state of stalemate where none dared to make the first move.
