The eastern continent was vast and boundless. Outside Taixia Country, there was a large, unpopulated wild area, which was covered with venomous animals and mutated beasts. With the sharp increase of the population in Taixia Country, Taixia Country's territory almost expanded every year. However, no matter how Taixia Country expanded its territory, there were always large gray-black areas outside those barren provinces in the north and the west, which indicated that they had not been exploited and explored yet.
Taixia country was adjacent to the ocean in the east and the south. Therefore, the unidentified gray-black areas were mainly in the north and the west.
