The Frail Eldest Daughter, Number One at Solving Cases

Yun Shuwan, a modern history researcher, transmigrates into the body of the eldest legitimate princess of the Great Jing dynasty. When she opens her eyes, the empress dowager's faction has already written her off as a pawn forfeit in the succession struggle, leaving her to wait for death. Her birth mother, the former empress, died young. The empress dowager suppressed her throughout her childhood, and her half-sister Yun Shuyao schemed to make her fall into the water. The court and the capital alike assume she'll be the first to fall. But Yun Shuwan, who has arrived from another world, is calm and calculating. She feigns weakness through illness and investigates in secret, piecing together clues to her mother's old injustice and a court grain scandal from a box of incense, a roster, and half a page of old military supply records. Han Xiao gives her his loyalty, Shen Zhiheng tests poisons, Chu Zhaoran organizes documents, and Yun Lie clears out hidden agents. Wen Yuchen weighs the situation with a cool eye, Lu Ji first looks down on her and then is brought to heel, while Ye Wang approaches with schemes from Beishuo. She isn't ruled by romance and she has principles. With every step carefully planned, she goes from discarded pawn to regent crown princess. The dead can't speak, but the living can.
