This long cave tunnel is actually a small ecosystem.
Xu Xin saw a stream of water flowing through the tunnel, forming an underground river.
Due to the sound of the wind, he hadn't heard the sound of the water below. It was only when he shone his flashlight that he noticed the situation.
There were also various creatures along the underground river.
These creatures appeared insect-like in appearance but were as large as tigers. Seeing them in this pitch-black underground space made one feel a bit creepy.
"Seems like giant insects are still living here. But these insects..."
Huihui was fast, and almost every insect vanished in the blink of an eye, but Xu Xin still managed to capture the appearance of a few insects.
Completely different from the giant insects he encountered before.
Previously, most of those giant insects were familiar creatures that had just grown larger. But these giant insects were bizarre in shape, some even frightening.
