Concocting

Emery wished he could do his potion-making inside the confines of the Khaos space. Unfortunately, he could not.

Thanks to his nine months trip all over the world, his [Spatial Storage] was filled to the brim with a few hundred new ingredients. If he had to analyze each manually, it would take literal months, but luckily the [Universal Flora knowledge] skill did most of the job for him, so he didn't have to experiment on all of them. What she needed to do was to separate the ingredients into different properties. One category for healing the physical body, one category for strength, one category for healing the mind, one category for the poisonous ones, and so on.
