I actually read solo farming in the tower from a comment talking about it in https://www.mangago.me/read-manga/hunter_world_s_gardener/ it's not as good as solo farming, but it's pretty nice.
This one is very curious, as it is about a traditional doctor getting transmigrated https://www.mangago.me/read-manga/the_crown_prince_that_sells_medicine/
This is not what you asked for but the vibes are very much there https://www.mangago.me/read-manga/underworld_restaurant/ I imagine you already know the greatest estate developer
Completely forgot

There's some fighting but it isn't the focus, as the MC is mainly a healer (and very baddass)
Thank you so much for the recommendations! (⌒▽⌒) I'll check these out
Just wanted to know if there are more manhwa like solo farming in the tower.. basically any action or rpg game like manhwa where the MC focuses on something that isn't fighting like food/cooking/architecture or just gets stronger or better in a unusual or unique way
