After defeating the Stone Demon, Rogel put away the Giant Corpse Hammer and began searching the surroundings.
The reason he came to hunt the Stone Demon was for its ore stash, after all, he wasn't lacking in monetary rewards.
However, before Rogel found the ore, he discovered a few corpses emitting a foul stench in a corner.
They were no longer recognizable as human, but from their tattered clothes, it was possible to faintly see that they were likely the three miners who met their fate.
Clearly, they had been brutally killed by the Stone Demon.
Rogel sighed slightly, and just as he was about to leave, he found a thin, blood-stained diary next to the corpses.
