Hell Stone 1
The Voiceless Abyssal looked like a place devoid of any life. Inside the long passage, Hiro couldn't hear anything. Even Milly, who kept nagging at him, her voice couldn't be heard when the two of them had entered the place.
No communication. No sound whatsoever. Hiro felt like he was walking in a very quiet world. Not even the slightest sound of the flames of the torches on the wall was heard. When his sense of hearing was no longer working, Hiro had no other choice but to sharpen his eyes with the help of the [Demon's Eyes]. He had to be more alert than usual because he didn't know when the monsters would attack and where they would come from.
After exiting a long passage, Hiro and Milly arrived at a T-junction made of rock that was damp and wet. Even so, no moss grew on the rock.
