The cavern was spacious, and even the slightest sound could cause an echo, so for a time Suming couldn't determine the exact direction of the noise. He could only guess at a general area, which seemed to be on a piece of the mountain wall to his front right.
There were more than a dozen openings of various sizes on the mountain wall. It wasn't long before a shadow flitted across the largest cavern mouth, and He emerged, clinging to the stone wall as he jumped to the ground, followed closely by the burly Da Xiong coming out from the same hole.
"Damn it!" Da Xiong cursed, rubbing his head, a faint trace of blood still visible on his forehead.
The caves inside the cavern varied in height; Da Xiong was tall and burly, which made crawling through the holes quite inconvenient. He probably had hit his head just now. He ignored him, taking a whistle to his lips and gave it a blow.
It seemed that this group was searching for something inside the cavern.
