"This is the everyday medical supplies section, offering special pharmaceuticals for various ailments. Would you prefer to look at the everyday medical supplies first, or the instance medical supplies?" The sales assistant, standing before a tall shelf, turned back to Gu Mian.
Gu Mian glanced at the shelf before him, then at the racks of instance-specific medication behind him. "Let's start with the instance ones."
At his words, the sales assistant walked over, reaching the shelf full of instance medical supplies in just a few quick strides.
"Our pharmaceuticals are categorized into four levels: A, B, C, and D. A-grade drugs are the most potent and expensive, but they can be life-saving in critical moments. B-grade drugs are next, and so on. D-grade drugs are the cheapest and have the weakest effects."
"A-grade drugs are on the top shelf, followed by B, C, and D. Right now, we're in front of the D-grade drugs."
