"I understand, I seem to understand…"
At this moment, he saw an excited expression on Ah Can's face, as if he had discovered some secret.
"What do you understand?" Ye Feng was also curious.
"There are marks on the four edges of this stone slab, and they are different in number." Ah Can hurriedly explained to everyone.
Ye Feng walked over with his flashlight, and indeed, he found four small holes at the edge of the stone slab.
These four holes weren't deep, so they were probably man-made.
Then, he walked to the other side and found that there were two small holes on this side, three on the other side, and one on the other side.
"What are these holes for?" Xu Jingxin asked a question that everyone was curious about.
