The voice gave Lightning goosebumps all over her body.
All the horror stories that she had heard from some other explorers flashed upon her mind. No matter it was a devil crawling out of the abyss, a ghost bearing a grudge or a lingering deathless, it would be an explorer's nightmare. A monster like that could kill a person simply by looking into his eyes and was good at creating illusions and deluding people. She was afraid that there was such a monster in this monument.
Despite that her father Thunder had told her that those stories were just nonsense made up by the worst explorers, she still got cold feet at this moment. "If it's not a monster, then what's it? Who can keep shouting inside in the same tone and at the same frequency for several months while being besieged by demons."
