Another cliched story about a young girl in ancient China that is betrayed by her relatives, there are at least 40 similar stories out there, so how does this one fare among this over exploited setting? Quite well actually.
To start with, all this stories have some sort of supernatural thing happen, the most common (over 75% of them) is transmigration of an ultimate female lead, which is quite dumb and boring imo. This one is on the second type of setting and the second most common one, she died and goes back in time, still kind of dumb but if used properly this only provides info so MC still needs to work for her food, and that's what happens here, MC doesn't miraculously gain medical skills or martial arts, she has to study medicine and based on a lucky encounter she attained by using her previous life experience. Simple but this kind of attention to consistency is not common and I like it.
Other than that, it's a slow story and it's still in diapers so there is very little to say, I keep getting annoyed at how the MC isn't more resolute in her actions but women in that era and setting were quite powerless, having a duche father makes things hard, it's a pity she doesn't want to stain her hands...
So, a good story so far making a proper use of a cliched setting that is usually muddled with conveniences. For those who care about proper development and justifications and for story consistency it's a good choice (so far).
Edit: Unfortunately it gets marred into a cycle, the same antagonists over and over. The MC put's their misdeeds in evidence so many times its annoying they are not done and over with. And the ML becomes more and more dislikeable, he cares little for the MC's will or her happiness. Add forced dramatic situations and the good points of the series progressively start to fade away. Other than an interesting FL there's not much left.
Maybe it'll get better again, but in my experience, when it starts going downhill it rarely gets better.
