Fortunately, with this small cave exit being near the entrance of the 3rd layer, they only travelled another 4-5 kilometers before spotting the black rocky mountain that Gong Yi had described in his earlier briefing.
This mountain appeared to be scored with wounds; its surface was pockmarked, with dense and numerous large caves covering the entire mountainside, causing it to appear just like a massive ant mount that had been exposed to the world. Just looking at the dense array of caves was enough to make people dizzy.
