I asked a couple people who reached level 10, they said it costs between 90m-100m. I'm waiting until I get 110m just to be safe.

Istoleyourtaco a few posts above mentioned 17mil to lvl 9.
Seems like there are quite a few ways to do this.
ninja I asked the first to reach level 10, Brain Akazuriua (I think that's how you spell his name), and he said it was 100m. But when I asked the fifth or ninth level 10 alchemist (I can't really remember their username or when they reached level 10, sorry), and they said it was 90m. So it seems to be getting cheaper.
