The group quickly followed after witnessing the scene.
The river they traveled twisted and turned for quite some time before they finally arrived at the entrance of a gigantic cave.
This cave towered ten meters high and spanned five meters wide, utterly pitch-black, resembling an abyss that seemed to draw one in with a single glance.
At the entrance of the cave, there was only a small river channel about ten centimeters wide, perpetually flowing with thick black liquid.
Xu Ran saw this and said, "This should be the origin of the river."
Tiger Girl, feeling a bit apprehensive, looked at the seemingly light-devouring cave and said, "Big brother, is this the entrance to the deep underground of Planet of Resentful Beasts?"
Xu Ran nodded and said, "It should be."
Tiger Girl took a deep breath and said, "If that's the case, let's go down."
Everyone nodded and together entered the pitch-black cave entrance.
