I hate it when authors start writing that world is almost the same as real world. And then medicine comes in... Always needless and herbs that all surgeons use and respect, pulses that can nearly detect your thoughts xD.
It's absurd. Totally ruins whole worldbuilding to me.
And since when person who can learn from book to manipulate air, doesn't try to learn magic or other things like "how to cure cancer" or "Can I fly?".
it is just stupid.
