Time immemorial, from ancient times to the present, encompassed The Lost Era, The Era of Demon Gods, The Devil God Era, The Taoist Era, The Ancient Era, and The Imperial Era.
The Twelve Demon Gods not only dominated an era, but even spanned the years, never ceasing to exist until today.
Such legends were living myths; countless civilizations were created because of them, and countless civilizations were also destroyed because of them.
Emperor Taizu of Great Qin, a striking figure through ancient times, once wanted to find them all.
However, after The Devil God Era ended, the Twelve Demon Gods faced their fates and ceased to appear in the world, leaving behind only occasional remnants of their projections and power.
Like Zhou Dao, who inherited the power of the four great demon gods—Dragon Hide, Black Sky, Void Aspect, and Heavenly Demon—these were traces of their continued existence in the world.
