Apart from this, Daning's peripheries are flanked by six huge stone castles, each with a circumference of several miles and a height of one hundred and twenty zhang.
The one hundred and twenty zhang of Daning equate to four hundred meters of the modern day.
That is to say, the height of these city walls is equivalent to a modern skyscraper a hundred stories tall.
Such exaggerated stone walls were designed specifically to defend against the descendants of the giant gods from the North.
These descendants, often ten to twenty zhang tall, and not infrequently reaching a height of fifty to sixty zhang, could only be fended off by the astonishing heights of these massive city walls.
Wang'an City is the key strategic point between North and South, the requisite passage for the Northern forces marching into the Southern states.
Therefore, this is not only the Capital of Daning but also a fortress to defend against the Northern descendants of the giant gods and Barbarian tribes.
