There were three types of universe life forms.
The first was the primordial godfiend stage.
The universe during this period was in chaos, and most of its laws were chaotic. The soil, sand, and stones became demons by chance and became the first batch of life forms in the universe. They were extremely weak.
In the words of the later generations, it was the contamination of the original material, turning the most ordinary soil and metal into spirits. Their bloodline was the most ordinary. In the later generations, even the strong would not be willing to be used as children or servants.
The second stage was the postcelestial stage.
As the primordial godfiends completed the laws and made the universe's environment suitable for the birth of life, life forms with perfect flesh and blood were born, and they became postcelestial lifeforms.
The third stage was actually the chaos heavens 'living being stage.
