Pill formulas were extremely important to a pill master. Whenever a pill master obtains a new pill formula, they would need to study it for a while before they could refine a pill.
Hence, this was how pill refinement competitions were conducted in the First City. Each party would bring out their own pill formula and exchange them. The opponent would then have to refine the pill based on the formula that they have obtained! The one who fails to do so will lose! Since this means that others would get to take a look at their own pill formula, not many people would initiate a pill refinement competition!
Bai Zhongtian would never have done this unless he had reached his limit.
"You mean that I'd win if I can refine a pill based on your pill formula?" Gu Ruoyun raised her brow and looked at Great Master Wu Yin as she asked indifferently.
