Su Junyu tilted his head and listened for a moment, then immediately made his judgment. "Two mid-Opening Spirit Stage demon beasts. By the rules, I won't intervene. Deal with them yourselves."
Demon beasts cultivated in a manner vastly different from humans. Due to the existence of spiritual energy, beasts of the Divine Land could accidentally attune themselves to the breathing of heaven and earth, drawing a tiny thread of spiritual energy into their bodies. This negligible energy stimulated their brains and souls, granting them intelligence and gradually demonizing them. This process was purely a gamble on beastly fortune—if they were lucky, they would embark upon the path of becoming demons. Of course, that was the case for the first generation of the Demon Race. Among demon beasts nowadays, far more were innately demonized individuals, born to parents who had already become demons.
For demon beasts to awaken their intelligence, they had to accumulate a certain level of demon power. This natural process of accumulating demon power was known as the Opening Spirit Stage. The demon power of an Opening Spirit Stage demon beast was roughly equivalent to the mana of a Qi Refining Cultivator, but Opening Spirit Stage demons generally had already awakened innate gifts, making them harder to fight than Qi Refining Cultivators.
After the Opening Spirit Stage came the Qi Accumulation stage, where one amassed demon energy in great quantities. After Qi Accumulation came the Demon Core. These two realms were respectively equivalent to human Foundation Establishment and Core Formation.
After the Demon Core, demons could control their flesh and alter their appearances. In ancient times, this realm was called the Transformation Stage. Its modern academic name was the "Pervert Stage"—but both cultivators and demons had tacitly forgotten that little detail and continued calling it the Transformation Stage.
