Thousands of years ago, the demons had fought against the experts of the Divine Martial Continent.
During that war, the Divine Martial Continent had almost vanished into thin air.
In the end, the Divine Martial Continent joined forces with the Demon Clan, the Sea Clan, and all living beings to deal with the Demon Clan. After tens of thousands of years of war, the Divine Martial Continent finally won.
Although they had won, the major races of the Divine Martial Continent had exhausted their resources, and their cultivation and civilization had fallen by a million years. Moreover, although the Demon Race had suffered a great defeat, they had not been expelled from the Divine Martial Continent. Instead, they had been driven to Youzhou.
In Youzhou, the demons were suppressed by countless restrictions, and countless experts guarded the demons.
