Lu Yiran was once a top player in "Nine Domains Huazhang", but when he woke up, he transformed into the white moonlight substitute in the game who was about to be discarded - Hanlin editor "Lu Yi". This identity is shady: if a woman disguises herself as a man and enters the court, she will be exposed as Ling Chi. What the original body left to her was only the humiliating memory of being used as a substitute by Pei Yanzhi, and a fatal sequelae: the price of photographic memory is randomly triggering "memory flashbacks" and reliving the pain repeatedly. Pei Yanzhi regarded her as useless, and the concubines in the harem laughed at her for not overestimating her abilities. But what Lu Yiran wanted was not the king's favor, but the authority of the entire court. She used her past life game memory and photographic memory to solve three unsolved cases in a row and bring together the two demon and spirit clans. She unexpectedly discovered that the taciturn colleague He Lianzhao beside her was actually a woman disguised as a man. When Pei Yanzhi finally realized that she was not a substitute but a threat, the secret of her identity was on the verge of collapse. A deeper conspiracy emerged: her awakening was not an accident, but a chess game after the rebirth of a certain "goddess". There was only one way left for Lu Yiran: to tear up the chess game first, and then have all the chess players kneel down and call His Majesty.
