The main difficulty in refining the Celestial Spirit Pill was the inclusion of a special ingredient in addition to the Spiritual Medicines: Magma Essence.
Under normal circumstances, Magma Essence felt merely warm to the touch, not hot at all.
But once a portion was separated and placed in a Pill Cauldron for Alchemy, it would instantly become scorching hot under the influence of the Martial Soul Fire, releasing a massive amount of heat.
Therefore, Chu Qingyun had practiced controlling this aspect thousands of times, not daring to be the slightest bit careless.
He only had that one mass of Magma Essence. If he wasted it, he wouldn't get another.
According to Chu Qingyun's estimates, the only other place to find Magma Essence in the Molten Rock District, besides the Fire Poison District, was within the large magma pits deep inside.
And he currently lacked the ability to go there and get any.
