Although Wanggu was divided into east, west, north, and south during the Ancient Sovereign Mystic Nether's era as well, the geographical boundaries weren't clearly defined. Mystic Nether also deliberately blurred these borders.
It was only when Mystic Abyss left Wanggu and the fragmented-face descended that everything changed.
Calamities enveloped Wanggu. The myriad races continued to experience death and war. Some races disappeared forever, and some races rebelled and ultimately evolved into the Five Great Races.
Among them, Flame Moon Mystic Heaven Race was in the east, the Northern Fate Royal Family in the north, the Empyrean Crimson Land Race in the west, the Underworld Origin Corpse Race in the south, and the number one race in the center.
These five large races stood at the peak of the present Wanggu.
