"This is the most comprehensive Alchemy class I've ever attended in my life... To think that the pill's effectiveness can be decided from the quality of flame alone." one alchemist from the group of fifteen said. A surprised look is still hanging on his face after he's enlightened by Qin Lan's theory class.
"I can't believe it either! Imagine to what quality of pills I can make if I followed this theory from the start? What a great point of view he made in his class regarding the extraction and nourishment process."
"But I am still curious... How can a simple fire-controlling class turn up to be so extensive, to the point it determines the efficiency and medicinal value of the pill? Not even the referencing book that I've read before talked about this." the students exchanged their views with one another after Qin Lan's ended the class.
