In the deep mountains of the Primitive Forest, there exists such a cave.
Inside are many rats, the largest being a meter long, with smaller ones—about a dozen—resting on the backs of the larger rats, and even newborn tiny ones.
They gnaw on the body of a dead giant wild boar, with the stench permeating the cave and countless bones of animals scattered everywhere.
The squeaking noise is enough to make one's scalp tingle.
Gu Xiaoxi and the others continued to press deeper into the mountains; after a day's travel, they arrived at the boundary of the deep forest, beyond which lay the Primitive Forest that no one dared to enter.
"Captain, do you see if that's a cave up ahead?" a team member called out urgently, setting down his binoculars.
Everyone followed his gaze and, indeed, there was a cave, not very large.
Kate, without hesitation, commanded two elites from the International Alliance, "You two go and check it out, see if there's any problem."
