Introduction to the Classification of Spirit Beasts
In the book "Soul Emperor", Xiao Du divides the levels of spirit beasts like this. They are divided into four major levels:
The first level is a beast. It has no intelligence and is just an ordinary beast.
The second level is the spirit beast. From level one to level seven, the spirit has been developed but not perfect. Only when it reaches level seven can the spirit beast form beast elixirs and speak.
The third level is the holy beast. From level 8 to level 10, heaven and earth will also rain down countless calamities to refine it, and it can mobilize the power of heaven and earth for its own use.
The fourth level is mythical beasts, from level one to level three, level one (domain), level two (territory), and level three (real world).
