The Su family was once a scholarly family for a century. His father, Taifu Su, angered the powerful officials because of his outspoken advice, which led to the execution of everyone in the Su family. Su Qingyan, who was only ten years old, escaped under the protection of his old servant and hid his name in the market.
Nine years later, she returned to the capital as "Mr. Yan" and took charge of the largest intelligence center in the capital, "Tingfeng Pavilion". She is not interested in money, but just to redress injustice. In fact, she wants to collect the truth about her father's case and use her "words" to clear her father's name in this turbid court.
