Using fire as the Pill Furnace can indeed continue pill refining, but without sufficient Cauldron Qi to nurture it, and no nature's spiritual energy for Xu Yanbing to absorb, even if Xu Yanbing refines the medicinal properties of the ingredients to the utmost, the chance of producing perfect quality Pills is very low.
And the only method for forcibly enhancing the quality of the Pills available to Xu Yanbing at the moment is just one.
That is, to use his own life force to improve the quality of this batch of Heavenly Human Pills, to bring out the full potency of the medicinal properties.
There were ancient Pill Refiners who, in the pursuit of refining an eighth-grade batch of Pills, exhausted all their vitality and life energy, and died on the day the Pills were completed.
Now, Xu Yanbing is also prepared in the depth of his heart to use most of his life force to ensure that each and every one of this batch of Heavenly Human Pills achieves perfect quality.
