Most demon beasts have demon qi that appears gray-black, like dense smoke emitted by burning wet wood, which indicates the chaotic nature of their bloodlines.
In contrast, demon beasts with pure bloodlines will have clearer demon qi. The Cyan Deer's demon qi is a hue of cyan, with only slight gray mixed in, almost unnoticeable if not looked at carefully.
Demon beasts instinctively purify their bloodlines, as a purer bloodline poses fewer obstacles to improvement. Once the impurities are entirely dissolved, the beast transforms into a spirit beast.
Fundamentally, all Golden Core Stage demon beasts fall under the category of spirit beasts, having refined their throat bone to speak human language.
The demon kings have demon qi as black as ink, representing the inheritance of the demon beast system, containing primitive beast nature.
Human Race cultivators domesticate beasts with the aim of weakening their beast nature as much as possible and enhancing their spirituality.
