Milo looked at Qian Cangyi with a curious expression.
Qian Cangyi was still uncertain:
"I need to go out and check."
The four of them walked out of the cave, and after a big loop, they finally found a crescent-shaped exit near a large stone that was close to a rhombus shape.
Qian Cangyi squatted down and peered through the gap into the cave, where he could see about a third of the cave.
"Let's verify this, Robert, go check out the cave for me," said Qian Cangyi to Robert.
"Ah… I should have just stayed below," muttered Robert.
"You need to know the route, and later you'll need to monitor the surroundings of the cave," Qian Cangyi explained.
After a while, Robert appeared within the line of sight of the crescent-shaped gap.
"Can you hear me?" shouted Qian Cangyi.
"No problem, very clear, though it would be better if the sound was a bit louder," Robert shaped his hands into a horn.
Qian Cangyi, who didn't hear very clearly, replied:
"Your voice is a bit soft, louder."
