After stepping in, Xu Yi felt countless 'Spiritual Energy' surging towards him.
Intensely, Xu Yi felt somewhat overwhelmed.
Within less than ten minutes, Xu Yi started to feel dizzy.
Unable to endure, his body absolutely couldn't handle the 'Spiritual Energy' of the sixth-level Fierce Beast Territory, it was simply too concentrated, his body couldn't bear it.
Therefore, Xu Yi quickly withdrew from the sixth-level Fierce Beast Territory.
"Do I have to advance to the peak of level five before I can move freely in the sixth-level Fierce Beast Territory?" Xu Yi murmured to himself as he looked at the sixth-level Fierce Beast Territory.
Sitting cross-legged, Xu Yi began his training.
After all, his body now contained a lot of 'Spiritual Energy', wondering if he could utilize this 'Spiritual Energy' to quickly enhance himself.
As a result, Xu Yi discovered that these 'Spiritual Energy' inside his body were not easily digestible.
