Shen Yu's green eyes narrowed slightly, a flash of genuine surprise rippling through his thoughts.
'Ninety-eight percent purity? Bai Ruolan... you actually managed to push the threshold by another two percent? You really are a frighteningly talented creature.'
To an ordinary cultivator or a low-grade merchant, a mere two percent increase might seem insignificant.
If a pill's purity was sitting at a mediocre fifty percent and someone raised it to fifty-two, it would barely warrant a second glance.
But in the peak strata of alchemical refinement, the difficulty curve scaled exponentially.
Shen Yu's own optimized recipes had already pushed the town's standard to a near-flawless ninety-six percent.
To extract an additional two percent from that absolute ceiling required an almost miraculous comprehension of the ingredients' spiritual properties, perfect heat control, and an immaculate execution that defied standard textbook logic.
