Was there a recommendation where the female protagonist traveled to ancient times to become the concubine of a prince and had the ability to catch ghosts? Then, the prince asked her to find the cause of death of the princess and write it into a novel?

I recommend "Reporting to Your Highness, the Princess Consort Can Catch Ghosts." The female lead of the novel had transmigrated to become the prince's concubine. Because of her acupuncture skills, she had won the prince's favor. Wangye told the female protagonist to find the cause of death of the main consort and gave the female protagonist a book as a hint. In the process of finding the cause of the death of the main consort, the female protagonist would also wander through some scenes of internal strife. I hope you like this fairy's recommendation.
