The valley might not be as vast as Warland Thicket, but it contained as many monsters. And even though the valley seemed like a normal rainforest, the danger level and death rate here were much higher than at Winterrock Peak.
Why?
Firstly, what would happen when the same number of monsters occupied a smaller area? Of course, the density would be multiplied. The moment one set foot in the valley, they would be greeted by dozens of monsters.
Secondly, not only were the monsters in Nefarious Valley aggressive ones, but they also mainly preyed on humans, or rather cultivators. Only when there were no cultivators to hunt would they attack one another. These monsters were called Demonic Monsters.
