"Has it mutated?"
Wang Ba looked astonished.
He could sense only a single life inside the eggshell, so there was no possibility other than a mutation.
"But... how could this happen?"
Successive peak masters of Beast Peak had all made dedicated studies of breeding Ghost-Patterned Stone Dragon Lizards.
Yet the offspring they bred were almost indistinguishable from their mothers.
Even the black markings on their bodies were exactly the same.
They were practically cast from the same mold.

It had explicitly stated that there were only three ways for a Spirit Beast to break through its current grade.

For instance, one cultivator's notes had recorded that he had once
