Modern military doctor Song Yaoyao, carrying the gossip system, time-travels to become an ancient minister's daughter, never expecting her inner voice to be completely overheard by all the officials in the court. The inner voice she inadvertently reveals exposes the plots of the previous dynasty's remnants and the truth behind a cold case, thus earning the emperor's appreciation and being appointed as a Diary Writer. From then on, every day during morning court, her inner voice, like a live stream, constantly exposes court secrets and stirs up the political winds.
