the MC character is way too overbearing... and the logic to get to the "make potion ability" is pretty BS... power to be a saintess, power to revive, see the future, luck... As we can see, that goddess is pretty easy to deal with, she could have even asked for a lot of abilities or something. The plot was too forced IMO (can understand better why the novel was so hated x'))
edit: and wait... she says she's the goddess they worship and all.. but the "god" of the earth just said last half chapter that they are just a race protecting the space-time continuum of their universe... urg, dang it, too much to say about the plot and I didn't even finished the first chapter, that's quite depressing. The good points that can differentiate from other isekai : 1) the MC is a female 2) the cheat is making potions. anything else make this story regrettable
