Uncle Jiang's analogy is quite interesting; the most important effect of the Pure Yang Pill is to assist in Bone Marrow Cleansing, which can improve a person's cultivation aptitude.
Zhang San's score improved from forty to sixty, implying that a person lacking innate talent can barely achieve entry level in cultivation. Li Si's score improved from ninety to ninety-five, indicating that a talented person has taken another small step forward.
From a utilitarian perspective, Zhang San improved by twenty points, while Li Si improved by five points. Of course, giving the pill to Zhang San seems more cost-effective, gaining an advantage of fifteen points.
But the situation isn't that simple. Even if Zhang San achieves entry level in cultivation, he might remain a Low-tier Sorcerer for life, with cultivation reaching at most Tier Two, while truly profound techniques can only be cultivated by High-tier Cultivators.
