Since the Mc got the game interface his cultivation state will be related to his level-ups. Every 1 level of cultivation will correspond to 2 level-ups.
This is what i decided to go with for the cultivation states in case of any changes you would like to see leave them in the comments and i'll change stuff accordingly.
