Sure enough, after swimming for about twenty seconds, the path ahead grew wider until suddenly reaching a turn, where there was a large opening directly above. Chen Tianlong knew that going up here would definitely lead to the destination.
No doubt about it, this was the spot leading to the secret tunnel in the cave from earlier. However, it wasn't in the direction of the factory, but near a small room along the way.
When Chen Tianlong was about to surface, he didn't rise directly but gently poked his head out. After observing his surroundings, he noticed many wet footprints, indicating that someone had just left here not long ago.
Seeing this, Chen Tianlong slowly crawled out of the water. What appeared in front of him was a large cave approximately one hundred square meters in size. It was empty, nothing but a hollow cave.
This must be a secret escape cave used by Earth Dragon.

"Mmm, let me go."
