The Ancient Night Secret Realm had several Ancestor-class demons and monsters.
Half of the ancient demon clans in that realm would work together to herd the overpopulated monsters toward the realm's portal and send them out to the outside world.
However, there were other goals. They would also be sending out 10th Rank monsters. After that, the ancient demon clans, including eight Demon Ancestors, would invade the outside world.
The most baffling thing was the invasion plan started because the secret realm's seal was broken due to a fight between two Demon Deities.
After obtaining more information, Ely's complexion paled as she could comprehend how chaotic the Terra World would become if the ancient demons and monsters from this secret realm joined the chaos.
It was still okay if it was just the demonic beasts. The allied forces outside the realm's portal could handle it. However, what about the 10th Rank monsters right at the beginning?
