I also rather enjoyed how the author went a bit tongue in cheek with acknowledging how the MC was Mansa Musa-ing the economy with her ability to create as much currency as she wants out of thin air. But I can see the issue abt how the author makes the MC deal with slavery become a hit or miss with readers.

I do want to clear up that, despite what another commenter says, it's shown clearly that MC did want to use her powers to just free everyone. Multiple times. And multiple times, she only didn't bc she was convinced to go along with another person's plan, which was more thought-out and better set-up to break down an entire slave system and reform a whole society, rather than just save a single group of people for the time being if MC did things her way. Whether or not readers will agree that going along with this plan was the best way to go abt dealing with this issue, is another matter.

The story also emphasizes that MC cannot replicate magic items. Most likely, this implies that she's also limited in other ways of what she can do with magic items, and that pretty much sets up the context clues that the slave keys/collars are some kind of magic item.

It's clear the author is going to seriously explore the whole transmigration aspect to the story, rather than just hand-waving it away, bc the MC is alive in her "real" world and does manage to return against her will. The way the author dissects the MC's mental process as she struggles to find somewhere to belong and her fears in losing that place is being well written, imho.

And I quite enjoy the obstacles the main couple faces, even with the introduction of imprinting (bc it explores how harrowing such a feature is for everyone involved--take that, Twilight /jk).

Tbh, I'd be happier if the ML had more interests in things beyond the MC bc there's a lot of potential with his situation. But idk if we'll get to see it bc the MC also has a lot of different focuses the author is setting up for her and all of those look like a lot of fun to explore as well (I'm most interested in seeing more abt the MC's new family, particularly as the mom/dad/sis is set up to be fascinating bc of hints that things aren't so clear cut in the family dynamic--tho the other wives and half-siblings are rather one-dimensional).

So she can create gold from literal air, and does it so often the former slave worried she was going to cause inflation all on her own. Yet, she can't create keys to the slave pens or the lock on the collar upon the slave's neck? There's zero indication that there's some kind of trap or puzzle or anti-magic anything on the locks or the collar either.

Oh, and she doesn't have a single thought of saving the slaves. It was, quite literally, brought up by the slave himself to destroy the slave system to its roots and she said NO. It's too much work.
