Thinking this, after the pursuers left, Wu Ma quietly asked, "How did the captain know there was a cave here?"
"Could he have been here before?"
Upon hearing Wu Ma's words, Shen Hou scratched his head and then said, also somewhat puzzled, "I'm not sure. It feels quite magical to me."
After speaking, he seemed to be stunned for a moment, then whispered, "By the way... during our escape, did any of you hear a 'rumbling' sound?"
"'Rumbling' sound?"
When Shen Hou mentioned this, the few looked at each other, and finally, Ding Xiaoliu, with a stern face, said, "I think I faintly heard something. But I was so rushed while fleeing, I thought I had misheard."
Hearing him say this, another team member from the Investigation Bureau named Dong Feng, as if suddenly thinking of something, abruptly turned his head to look at the cave wall.
