Hou Niao began his patrol career, honestly, it was his first time.
Yinyue Castle, Ironwood Castle, Black Soil Castle, Three Mountains Castle, King's Castle... and so on, a total of thirteen places, he had to visit each of them. According to the internal rules of patrollers, barring unexpected events, he was supposed to visit all the fortresses within a month, which was not difficult,
For instance, Yinyue Castle and Ironwood Castle were only a half-day's journey apart on foot. Some fortresses were so close to each other that from the highest point of one, one could even see the spire of another.
After all, he was not patrolling the entire Yinling, but only part of it; Tianfeng Plain was the state county, Jin City was the state city, places like Jiangyou, Miao Gao, Yinling, Bimu Hill, Black Swamp and such towns were county domains. The area he was responsible for patrolling was roughly comparable to a township? Just a slightly larger township.
