The Demon Race Underground City was a product of the Demon Race's massive invasion of the Divine Protection Continent.
At that time, the Demon Race was at its peak, causing the Continent Alliance to cry out, almost powerless to resist.
But fortunately, it was also a period of rapid player development. Because of their activity and "Undying Body" attribute, the Demon Race never managed to completely conquer the last continent of the Miracle World.
What was originally a crushing offensive was forcibly reversed into a tug-of-war, infuriating the Demon Race's upper echelons, who then decided on a plan to take down the entire Miracle World inch by inch.
Constructing the underground city was their method to deal with the Continent Alliance reclaiming lost territories from them repeatedly.
You can take back the fallen lands, but underneath, they're all my Demon Race's underground cities. Can you still sleep soundly on top, or even march across these lands to attack further?
