The flames controlled by the two of them appeared to be nothing more than ordinary fire being used to burn things. Ordinary people simply could not see the mysteries within and would easily assume that this was merely the effect of flames and techniques.
But in truth, fire control was not something that could be mastered with mere words. Uncontrollable flames could never be used to refine pills. No matter how exquisite one's hand seals were, no matter how special the flames used were, successful pill refinement would still be impossible. Those who did not understand pill refinement often believed it meant tossing Spirit Medicine into a pill furnace and burning it with fire. That was, in fact, utterly wrong.
Those with keen eyes, however, could see that the two men's control over every subtle aspect of their flames was exceedingly exquisite. Each lick of fire gently nudged certain patterns on the medicinal wood boards, the movements so slight as to be nearly imperceptible.
If the force was too great, it would burn away the Spirit Medicine within, and these Spirit Medicines were exceptionally fragile. But if it was too light, it could not shift the patterns on the wooden board. That would only waste time for nothing.
The flames had to be controlled with perfect precision to achieve the best effect. In terms of such fine control over flames, Huo Hai could only sigh that he was inferior. Though his flames were of a higher grade and possessed greater power, and though his own strength and Mental Power far surpassed theirs, in the matter of flame control, he truly could not compare to them by a long shot.
No wonder his pill refinement always had such a high failure rate. Only after enormous amounts of practice could he achieve
