"It seems we are safe for now, but I have no idea where Baldy and Niu Dan have gone. We've been running for half a day and still haven't caught a glimpse of them." I was feeling a bit strange as they had left before us, but we had been running for over ten minutes. By all logic, we should have caught up with them by now, yet there's no sign of them, not even a ghostly shadow.
"Baldy! Niu Dan!" Luk Yu's father called out after hearing what I said. His voice echoed time and again in the passage, but there was no response from Baldy and the others.
"Uncle, did you notice any side paths when we came down just now?" I suddenly thought of something. Maybe there were side paths in this tunnel, and we hadn't all gone the same way, which means we might have gotten separated from Baldy and the others.
"Side paths? I didn't notice—I was too busy running at the time," Luk Yu's father shook his head, turning his gaze to Luk Yu.
