For the other provinces, Yan State's DaHuang Mansion symbolizes the border, or rather, many believe that DaHuang Mansion is synonymous with the border.
Even Gu Chen had always thought so before he arrived in Yan State.
However, the truth is different; Yan State is located in the western region of the Nine States, and to the extreme west, adjacent to the vast mountains, only past DaHuang Mansion lies the true border.
The closer one gets to the border, the more desolate the environment becomes, and the more barren mountains there are.
The name DaHuang Mansion derives from this reality.
The imperial court had established several military towns along the border, with six hundred thousand XuanTie troops stationed there. Well-equipped and strictly disciplined, they replaced Da Xia in guarding the border over generations.
