This is an "evolution" story of palace fighting without cheats. The heroine Shen Qingci was originally the daughter of a general, but after her family was wiped out overnight, she became the most despicable female widow. With a blood feud in mind, she stepped into the palace with the help of a bizarre murder case of a palace concubine. In the deep palace, everyone is a chess piece, but she has to be the one who plays chess. She used autopsies as a blade and human hearts as a chessboard to search for clues from each cold corpse, uncovering conspiracies that had been carefully covered up. From a little female official who could only protect herself, to "Shen Sizuo" who solved strange cases and won the emperor's admiration, and then step by step to uncover the mastermind behind the massacre that year, and finally assisted the emperor and gained power in the government. The heroine's evolution is a battle between intelligence and humanity. She does not rely on favor, but only relies on the scalpel and careful mind in her hand to blaze a bloody path from hell to the top of power.
