Creak, creak, creak, creak!
The sound of bones rubbing against each other could be heard, and it traveled far in the black mist. If The Black Mages on the ark heard this sound, they would immediately know that it was the sound of a large number of skeletons moving.
Unfortunately, they were not on the ark continent. They were in the underworld, so it was not strange to hear such sounds everywhere.
Rows of gray skeletons were slowly moving forward in the black mist. These were the little skeletons at the bottom of the underworld. Only these skeletons would make creaking sounds when they walked. The higher-leveled skeletons would not make such sounds.
In the underworld, these ordinary gray skeletons that wandered around all day without any intelligence had only two uses. One was to be used as cannon fodder, and the other was to be used as food by other undead creatures. Besides these two uses, they had almost no other use.
