The Eastern Region was also known as the Holy Sword Land.
Within the Holy Sword Land, there were 108 realms.
One realm encompassed three different types of counties and cities.
The Eastern Sky Realm was one of the more famous of the 108 realms in the Eastern Region.
With Dongtianwang City at its center.
Although it was named after a city, its size was almost the size of a county.
Dongtianwang City had all the teleportation spiritual array leading to the 36 upper counties of the Eastern Sky Realm.
But currently, no teleportation portals were leading to the middle and lower counties like the Tiansang Prefecture.
Therefore, if the people in the central region wanted to go to the White Cave, they had to use teleportation portals in the other realms until they reached Dongtianwang City.
