The greatest difference between demons and humans is that demons do not draw upon the Power of Heaven and Earth through Artistic Conception. Instead, they rely on the demonic power refined within their own bodies. Even though their demonic power is robust and they can also extract Yuan Qi from Heaven and Earth to circulate slowly, compared to Artistic Conception, which can almost endlessly mobilize the Power of Heaven and Earth, the gap is simply too vast.
A human Martial Artist, even if they are at the Five Viscera Realm, as long as they have mastered one or two kinds of Artistic Conception and combine it with their own Yuan Gang, it is nearly impossible to exhaust their powers, whereas demons cannot do the same.
This is why a Seventh Rank Demon King has near-Grandmaster abilities, but any expert on the Wind Cloud List does not fear them and is confident of overcoming and ultimately slaying them.
