China is divided, and in the north there is King Dingbei who dominates the vast sea and is powerful in Mobei. In the south there is Emperor Nan Tian who is in charge of Jinling. Although Daliang in the Central Plains is called orthodox, it is actually divided by vassal kings, with undercurrents surging in the court, and the forces of the rivers and lakes are even more intertwined - one government, two temples, three mountains and four sects equally share the fate of the rivers and lakes. The three realms of martial arts (Qihai, Tongmai, and Shenren) are heavily fortified. The legendary realm of "unity of man and nature" has long been extinct.
