To the south of Green Mountain State lies a vast state domain, covering an area of hundreds of thousands of square kilometers, but it is not suited for the survival of mortals.
For it was once the bridgehead for the Water Devils' invasion of the continent; in that battle, countless Water Devils and Cultivators fell, and the fierce war even sunk the land into the sea, leaving only a few scattered islands visible now.
For a long time afterward, this area was the domain of the Water Devils, and the Cultivators paid a heavy price to reclaim it. They then transformed it into an inner sea by means of reclaiming land from the sea, hence it was called Cang Hai Province.
