Yan Ketao asked curiously, "Can I go up and have a look?"
Upon hearing this, Chu Jingtang turned around at the entrance of the cave, and Shen Moming also stared intently at Yan Ketao's facial reaction.
However, Wu Jinliang casually waved his hand and said, "We're all friends here. Feel free to look around. Come on."
Saying this, he jumped up first, leading the way.
Yan Ketao immediately followed. Once at the top, he indeed found a small space surrounded by little windows meant for observation.
He looked very carefully and even checked each window before asking in confusion, "These small windows are fine for watching from, but how do you pass messages through them?"
Wu Jinliang said, "Naturally, your Elder Jin would bring the messages over. When he strolls over here, or pretends to urinate while secretly slipping the message into this spot when no one is paying attention, we'd pick it up and bring it back to your little master and the others."
