Somewhere in the netherworld, five demon lords were gathered on a high hill where white bones were piled up.
These demon kings were red all over, with purple lines on their skin and a pair of exaggerated long horns on their heads.
They had extremely hard bone armor on their vital parts, and they also had natural protective runes.
The rune would take effect once it was attacked, and it would gain various defensive effects.
A cold glint flickered in his dark green eyes as he looked at the wilderness in the distance.
Looking at the runes between their eyebrows, it was clear that these five proud Demon Lord overlords all had high-level bloodlines certified by the demon gods.
The low-level demons nearby all stayed far away, not daring to come close.
The demons had gathered here because they had received a message that a mutated demon was crossing the border.
