After the Spirit Prohibition shattered, the first thing that surged out like a breached dyke was the imposing Demon Power.
What is Demon Power?
It wasn't the oppression of Demon Energy, nor was it a kind of Divine Skill of a Demon Beast. If anything, it was similar to Martial Arts Boxing Intent; it was a form of mental suppression. This might had nothing to do with strength and was closer to what one might call a "temperament." According to Modern methods, it was a byproduct of the "algorithm of consciousness" in action. Unlike the Shenzhou People Clan who experienced Innate Spiritual Awakening, it was incredibly challenging for the Demon Clan to even acquire Spirit Wisdom. Each member of the Demon Clan was an extremely emotional being, making it easier for them to develop abilities akin to Martial Arts Boxing Intent. Demon Power was the sediment of primeval wildness transforming into civilization.
