Great! But I think we will do it gradually in-fiction, Li will discover some talents and interests in Alchemy. And slowly gain some skill is in it(probably changing it from Science as you said, as I don't want to 'waste' so many advances to get it by itself, as that would mean Li staying to much behind others in terms of development - I think. Maybe Amiko or Lonjiku Kaijitsu have some knowledge about Alchemy?
We will see:)
But, maybe: Is there a way to gain Alchemy by in-fiction/game training, by i.e. paying for lessons? As not to 'waste' advancement for it?
