Hakkar was scared out of his wits when he saw the mark on the evil God's head.
At this moment, it didn't even have the thought of resisting.
In the great domain of hell, there were many powerful races, so there were many taboos that couldn't be violated.
For example, they were not allowed to step into the territory of certain gods, and they were not allowed to destroy the formations set up by certain gods.
However, what left the deepest impression on Hakkar was a taboo left behind by the ancient Abyss Dragon King.
This taboo described a divine seal, which was formed by a Burning blood-red eye.
According to the ancient Abyss Dragon King's description, this divine seal was a taboo for all races in the great domain of hell. Even the races of the ancient gods couldn't avoid it.
Because this divine seal symbolized the Supreme authority and inviolable authority of the great domain of hell.
