After seven hours, both Pill Kings had successfully extracted the medicinal essence from the ingredients. However, the moment that was done, the real challenge began.
They now had only eleven hours to burn impurities, condense the pill, and refine it to Tier 12. All this had to be completed without making a single mistake that would compromise the impurity-burning or condensing process.
As usual, it was a race, and they had to be sure to stay just a step ahead of perfection, or else they would both lose.
Pill King Han Lu was the first to initiate the purification process.
Kent paid close attention to him, and what he saw amazed him.
Pill King Han Lu activated his classic impurity-burning technique, the Butterfly Burning Art.
It was one of his signature and most frequently used techniques. Some say it was self-created, while others claim he obtained it from the Lost Pill Immortal Tomb.
