The rules could not be disobeyed. Once one was restricted by them, one would feel helpless and sad.
Just like this group of mutants, they were like domesticated cattle, sheep, pigs, and dogs, without any freedom at all.
Once the grazing cultivator gave the order, they had to run obediently without a moment of rest.
With another order, they had to either attack the innate divine embryo or devour the corpses of the innate gods.
The process of devouring a God's remains was not enjoyment, but unspeakable pain and torture.
For mutants, the corpses of gods that contained divine source could not only help them evolve, but they were also the most fatal poison.
It had devoured the innate divine remains and turned into a mutated divine embryo that was neither human nor ghost.
After being refined by the divine fire, the mutated man had already gotten rid of all the residual poison, and his body was as transparent as flawless glass.
