The One-Line Sky Forest was Hive-like's easiest newbie stage. Even if they couldn't use their Skills, very few people would die here.
Those unlucky ones who died were not careful enough and attracted a large number of wild dogs. They were then surrounded by these little guys with extremely high attack power and killed with normal attacks.
But...
This was only the fate of human Professionals experienced.
Their efficiency in obtaining the admission passes was too low.
On average, there was only one every few months, and they couldn't form a team with other human challengers at the same time. Therefore, they basically entered the arena alone and fought the likes of Hippo Behemoth and the group of wild dog monsters alone.
As for the challengers from other planes, they had a stable channel to obtain an admission pass and could enter Hive-like with their friends from the same world. Furthermore, they could enter the Hive-like dungeon multiple times.
