The height of the underground cave was not very tall, maybe around four or five meters.
Phil landed steadily and first sensed the surrounding pollution situation.
Faint traces of pollution were gathering towards the depths of the cave.
She felt that this pollution had a tendency to become stronger gradually.
"Is it because of the invasion by Deep Sea Demons?"
Deep Sea Demons originated from the Era of Calamity, a realm humans struggled to resolve; the Era of Calamity only addressed land, but not the deep sea.
Even now, people's understanding of the deep sea remains very limited.
Maybe it has already taken the shape of the Abyss.
Phil looked towards the direction the pollution was coming from, and it was indeed the deep sea.
The girl furrowed her brows.
"Did the array Hilia discovered attract Deep Sea Demons, and after being killed, the resultant pollution quietly gathers here?"
Phil thought this possibility was very high.
