The more Yu Ziqing researched, the more he felt that the demonic cultivation methods seemed to correspond closely to the secret techniques and divine skills of the human cultivators.
As foundational cultivation techniques were researched by humans, various strange secret techniques might have been discreetly adapted from other races.
If the Black Sky Devil God Qi was treated as a secret technique for cultivation, there wouldn't be much of a problem, nor would it affect his foundational cultivation techniques.
His foundation still remained in Body Refinement, coupled with Refining God, taking the path of the Hungry Ghost Dao.
Without Qi Refinement, Yu Ziqing could only use his qi-blood to forcibly refine the egg of that demon; a thread of pure and violent Devil Thought emerging was promptly stuffed between the teeth by the Yin God.
This left only a strand of the purest power, uniquely belonging to the Black Sky Devil.
