287 Perfect Pill

"What!"

Duan Shu was in shock when she glanced at the pill in Chen Tian's hand.

The purity of the pill in Chen Tian's hand was unlike anything Duan Shu had ever seen before.

"Completely pure!" Duan Shu could hardly believe her eyes.

The hardest thing for an alchemist was to achieve such a high level of purity when concocting a pill.

Even an alchemist king like her could only achieve 99% purity; there would always be this 1% that couldn't be refined, no matter how skilled the alchemist was.

Maintaining purity becomes more challenging with higher-grade pills.

Don't look down on this 1% of impurity because even the slightest difference could have significant effects on the effects of the pill.

For example, a top-notch 99% pure Ironwood Pill could increase raw physical power by 20% for a duration of 2 hours.

An Ironwood pill with a similar grade but a purity of 90% would only increase physical power by 16% for the same duration.
