This is an extremely large deep cavern, with an estimated depth of at least over 300 yards, and a diameter of over 1,000 yards.
Soon, Rod spotted a white cocoon on the cold rock wall.
The source of the Fire Mark's sensing was inside the white cocoon.
Mephit raised his voice: "That's the Dissolving Cocoon! They're captured, the monster sealed them in the cocoon, trying to completely dissolve their souls and absorb nutrients."
White light flashed on Rod's hand, and a Star Line shot out, quickly forming into a Star Sword.
He flew over and slashed open the white cocoon, a thick white liquid gushed out, and a warrior fell down.
Rod reached out to catch him, not paying attention to the white liquid.
A scorching sensation on his skin proved there was acid in the white liquid, and a decline in humanity indicated its soul-polluting nature.
However, his state still looked good, his soul hadn't been severely eroded.
