Wen Wan, an orphan girl from Jiangnan salt merchants, suddenly lost her loving father. Her stepmother forced her to enter the palace with a suspicious "suicide note". He was assassinated on the way, and a mysterious man rescued him but left behind the family heirloom jade pendant. After entering the palace, with a humble business background, she was sent to the desolate Jingyixuan.
The palace is as deep as an abyss, full of murderous intent. The poisonous ravings of the abandoned concubine in the cold palace became her first lesson. A palace epidemic forced her and the medical girl Qing Dai to rely on their "poison-recognizing" wisdom to survive in desperate situations, and unexpectedly gained access to the library.
Under the fragrance of ink, there is a turbulent undercurrent. She meets Xiao Yu, the seventh prince who is disguised as a bodyguard. The huge Jiangnan salt tax case he is investigating is actually connected to the mystery of her father's death! A fragment of a scroll and a string of secret words start exploration and cooperation. When she helped him decipher the mystery of the account books, he took out the Wen family jade pendant he had found when he rescued her - the intertwining of identity and purpose was instantly complicated.
The salt tax black hole is bottomless, and the shadow of the mastermind behind the scenes is shrouded in shadow. Wen Wan uses her businessman's wisdom and photographic memory to weave a web in the silent place, hiding the enemy in front of her. The relationship that arose out of suspicion with Xiao Yu has gone through betrayal, pain and the test of life and death.
Bloody palace walls, imperial power changes. To protect the one she loved, she used her body to block the sword and narrowly escaped death. On the day he woke up, on the dragon chair, Xiao Yu held hands and asked. From a merchant girl in the south of the Yangtze River to an iron-fisted queen, she used her unparalleled wisdom and tenacity to clear up the dynasty, reform the long-standing shortcomings, and create a prosperous era in which the emperor and the empress are jointly in charge.
See how the orphan girl breaks the chess game in this cinnabar-stained palace and becomes a phoenix.
