"Dragon Transformation Pill" is a relatively high-level Spirit Pill, typically requiring extended periods for concoction.
Zhou Chun knew some alchemy basics and understood that Spirit Pills like "Dragon Transformation Pill" usually required a longer time of nurturing to dissolve the inherent poison and enhance the medicinal strength of the pill.
In fact, regarding the preliminary steps of drug refining, merging, and combining, Luo Qingni had completed them in less than a day.
However, as she had previously mentioned, the nurturing time required afterwards ranged from seven to nine days, depending on the situation.
Hence, during the subsequent days, she simply maintained a small True Fire to nurture the Pill Furnace, focusing most of her attention on observing the medicinal liquids inside, intermittently casting nurturing spells to cultivate the Spirit Pill.
This is what is often said in the path of alchemy: three parts are in refining, seven parts in nurturing.
