Chapter 3703: Refining the Azure Wood Restore Spirit Pill

The concoction of the Celestial level alchemical pill was slightly more complicated. Merely the formation alone was not enough. It also needed an alchemy cauldron, which was very important.

Because the quality of the cauldron would also affect the quality of the completed pill.

Ling Han didn't have a good alchemy cauldron in his possession right now, so he could only use the Primal Chaos Extreme Lightning Tower as a replacement.

Why was the cauldron so important?

This was because an alchemist's cauldron was like a Spirit Tool. It would be fused with a sliver of divine sense. Thus, it would be extremely sensitive to changes in energy, and alchemy was actually using energy to extract the medicinal properties, guide the medicinal properties, and fuse the medicinal properties.

The more sensitive one was to energy, the higher the chances of concocting alchemical pills, and the higher the grade of the completed pill.
