In the Kawa Great Forest, the deeper you go, the higher the tier and stronger the monsters that roam the forest.
The higher the danger,
naturally, the fewer Beastman Tribes survive around.
Through the Stone Peak Forest, the Dragon Nest Legion entering the inner domain encounters resistance that is several times stronger than in the outer domain.
Those monsters rampant in the mountains and forests are simply difficult to achieve a complete cleanup.
In fact, the expansion of the Dragon Nest Territory to such a vast region nowadays, due to population concerns, it is impossible to attack a place and completely sweep away all the monsters there.
The farther away from the Dragon Nest Base, the longer the supply line, making expansion increasingly difficult.
Before the Dragon Nest Legion reached the Stone Peak Forest, they basically conquered a region suitable for development, cleaned up the monsters around that area, and then relied on the Stronghold City for outward expansion.
