His soul power carefully controlled the Purple Flame as it slowly roasted the mutually resistant medicinal powders.

After all, if analyzing formulas were truly so simple, formulas would not be worth much...

The Purple Flame within the medicinal cauldron violently churned, and with a low curse, a burnt smell wafted out from the cauldron.
