The Dajing Dynasty set up a historical museum to record the history of the country, but no woman ever served. Su Yan, who came from a poor family, relied on his photographic memory and solid historical skills to break a century-old tradition and become the youngest editor of the history museum. Faced with the contempt of her colleagues, the difficulties of the nobles, and the disputes over the authenticity of the history, she did not cling to the powerful and was not afraid of threats. She only used her pen as a blade to verify the records one by one, from palace secrets to local disasters. In a male-dominated history museum, Su Yan spent ten years growing from a low-level editor to the Taishi Ling in charge of compiling national history, making the imprint of "women can also compile history" forever engraved in the history books of Dajing.
