The entire underground fault world was silent, with no changes.
…
Whiz, whiz!
About half an hour later, a handful of figures appeared.
The Sky Thunder Rat, Old Snake Turtle, Big Black Tiger and Black Mountain Bull - the four Demon Kings appeared. They stared at the formation barrier in front of them, their eyes full of surprise. They looked to the left and right, as well as underneath them.
The Sky Thunder Rat couldn't help but exclaim, "Where did it go? How come it's not visible?"
The Old Snake Turtle, with a snake-like head, flicked its tongue, its eyes cool and calm. It didn't say anything but seemed to be deep in thought.
Next to it, the White-Eyed Soul Tiger's eyes shone with a strange light. A mysterious soul power searched around again and again, scanning the sides and the bottom. Finally, it said with a furrowed brow, "No trace."
The old Black Bull was immediately surprised, "That's incredible. It didn't go inside, did it?"
