How to become an villainess(DROPPED)

This novel have a good idea, but the execution is... regular. Firstly the writing is fast, TOO FAST, the actions doesn't be explained, and there are a totally fault of descriptions and some details. The characters' actions are sooo cliches; the guard, the apothecary, the merchant, etc. The MC is inexplicable too. She isn't thinking about her situation, things like "WTF IS THIS SYSTEM" or "WHY IS VILLAINESS SYSTEM", she accept all so fast and doesn't have any thinking about almost nothing, for example her own world. You should make a space to explain his character, because right now I don't have nothing. Other thing about the world...Where is this novel? In a first look is in a typical cultive world, but how in the name of budda the MC knows about medicine?. I mean I was thinking that she was in the same world but the lack of technology contract my theory, and his body is a maid's body, so she shouldn't have those knowledge. There are other things but, I don't want to write more about errors.
