Searching around the area where those Fiend Demons appeared from, Long Haochen and his teammates finally found their destination, the Desolate Hissing Cavern.
Rather than saying this was a cavern, one should say that it was a crevice.
The crevice was three meters broad, six or seven meters high and the interior was pitch-dark. With an unknown depth, countless cracks covered the cave’s wall, clearly made from the terrifying sound waves.
Using his spiritual energy in an attempt to inspect the hardness of the rock, he figured that it was even harder than granite.
After observing this place, everyone looked at Long Haochen and Lin Xin unhappily complained, “This mission the Alliance bestowed us is really quite something. They didn’t make it clear to us that the Desolate Hissing Cavern was such a terrifying place. We haven’t come prepared at all.”
