Slow
It didn't take long for Ryu to notice something quite curious. Each one of these spatial rings contained at least three sets of ingredients. Some included four or five, some even had as many as ten.
Of course, these weren't attempts at bribing Ryu, nor were they asking for more than one pill to be formed. Rather, it was simply common practice.
When asking for an alchemist's work, not only would materials be provided, but several sets of them would be, in fact. Depending on the difficulty, more or less ingredients would be provided and if the minimum number wasn't met, then the commissioner would have to accept the possibility of failure.
If the minimum threshold was met, then the risk would be on the alchemists shoulders. If the alchemist failed, they would have to procure more materials themselves to complete it at no extra cost.
However, to Ryu, all he saw was free money.
