Wei Wuyin discovered the end result of the Refraction World-Light Elixir was somewhat different than what he had expected. Peering into the liquid, he saw a semi-perfect reflection of himself as if staring at a liquid mirror. The only faint difference was the glimmer of white brilliance that emanated from its surface, changing the contrast of his image.
"This is a peak-quality elixir…" He was indeed surprised by the quality of the product. When one used the Thirty-Three Earthly Concoction Method, the end result typically was of a lesser grade, ending at the low-quality level.
When a product was impure-quality, it contained unhealthy impurities and its primary effect reduced considerably. But when a product reaches the low-quality, as known as the lowest state of perfection, it has absolutely no impurities, no drawbacks, and achieves 100% of its intended effect. This was known as the Alchemic Standard.
