It has been almost three months since Roan began to study alchemy. Three weeks earlier, Roan finally concocted his first Energy Gathering Pill. However, that was not enough for someone to become an Earth Low-Level Alchemist. Neutral pills are always easier, so the alchemist guild couldn't take those as a sign of ability unless they were hard pills to start with.
As one can imagine, a simple Energy Gathering Pill was simply too far from being considered hard in the alchemists' eyes. However, if the alchemist makes an Elemental Type Energy Gathering Pill, the story will be totally different. Elemental Pills don't just give better results. They are also much harder to concoct.
