Qin Yu had the pill formula for the Heavenly Essence Pill.
This pill formula was actually not a rare item. It was just that to refine this pill, one needed top-notch pill skills. There weren't many people in the world who could refine this pill.
In the current era, there was no accurate division of ranks among alchemists. However, Qin Yu had powerful divine sense and purple fire, so he was quite confident in himself.
Qin Yu followed the pill formula and put the herbs into the cauldron. Then, he slowly refined the pill with the purple spiritual fire.
To refine the Heavenly Essence Pill, it was very important to control the temperature of the flame. This required a powerful divine sense.
Golden light shot out from Qin Yu's glabella, and primordial spirit power burst out, refining the pill with great precision.
As the herbs melted one by one, the medicinal fragrance slowly spread out.
