Seeking the title of this novel, the female protagonist is a mystery of ancient times

I only remember a few things
It was written in the first person of the female lead. It seemed that the female lead had a good family background. The beginning of the story seemed to be about meeting her fiancé.
The female protagonist was very smart. She knew a little martial arts and had a master. After that, there were basically small-scale cases that were solved in episodes.
In one of the cases, it seemed that the female lead didn't eat fish or something, so she could tell that the person was in disguise.
The name of the novel seems to have the word Liu or Qing or something
Ask the big ones to tell him.
No, no, I just read it. It's not a transmigration event book. Besides, I'm sure this novel is not transmigration.
The female lead also gives people a faint feeling
The whole article wrote that there were not many love scenes with her fiancé.
However, when I saw it, it was not over yet. The development after that was not very clear
There was a case that seemed to be related to a zither or pipa. Many seniors gathered in an inn, and many people died. In the end, the female lead solved the case because the murderer pretended to be her master and told her to eat fish, but she never actually ate fish.
It was also the temple that she went to pray for. It was said that praying for a child was very effective, but in fact, it was only in the end that she found out that it was a monk who raped a girl.
That's probably all I can remember.
He found the spring rain was like wine, Ruyan Liu.
