After contacting Dao Meihua with the walkie-talkie, the female team members stayed here, and Chen Ying and Ying Bo followed the Big White Monkey to the entrance it mentioned.
"Squeak, below."
The Big White Monkey pointed to the gap between two peaks and jumped in first.
With a height of more than four meters, you can use the protruding rocks in the middle to support yourself, and as long as you're careful, there won't be any problems.
Once they got down, they discovered it was a narrow gap, about two meters high and around sixty centimeters wide, that could be easily entered sideways.
The gap was about one meter. After passing through, there was a downward sloping path with stone walls on both sides that seemed to belong to karst geology.
Going into this gap, there were two stone platforms over a meter high. After descending the second platform, the sky visible through the gap was reduced to almost a single line.
