Demon beasts were a rather peculiar breed of creatures. Due to how proliferated the demon race and the beast race were across the many worlds, they could be found almost everywhere.
Many beasts often had traces of demon bloodlines in them and the only thing that mattered was if it was pure enough or not. If it was pure, they would be able to awaken it and become a Demon Beast.
If it was not pure enough and had a lot of bloodlines mixed, it was called impure. Beasts with this were unable to awaken it, but there were still some beasts who, through some stroke of luck or a fortunate encounter, manage to awaken that bloodline.
The Ugly beast in front of Lin Mu could be considered to be one of those lucky beasts. It very clearly had a muddled bloodline, and its effects could be seen on its physique. The most common difference that was there between Demon beasts and normal beasts was the fact that they could actually gain humanoid forms way faster.
