In this beautiful world, light and darkness maintain a delicate balance.
Wei, the first queen of the Demon World, broke this balance. She awakened the ancient dark power hidden in the Demon World: Decline, Eternal Night, and the End of the World to help her seize the dominance of the Demon World and establish an unprecedentedly powerful Demon Star Empire.
But the existence of the apocalypse is becoming more and more frightening - his powerful dark power has caused an imbalance in the power of light and darkness...
Therefore, at the end of the Mowei century, under the joint seal of light and darkness, the apocalyptic priest with great military exploits fell into silence.
Thousands of years later, the second queen of the demon world was born, but was assassinated by her half-brother to usurp the throne... In order to regain what she deserved, she chose to reawaken the sealed ancient dark power!
