Lin Nian, a doctor of modern criminal psychology, passed through the Dayin Dynasty in an experimental accident and became Zhaoyi Yu Wantang, who was sent to the cold palace for "cursing the prince". When she was on the verge of death, she bound to the "Fengming Palace Fighting System" and obtained the "Mind Reading Skill" (limited time/consumable) core golden finger. She must complete the tasks issued by the system to obtain survival points, skills and props, and return to the center of power from the cold palace.
In the early stage, Yu Wantang used her mind-reading skills to see through the malicious intentions of the concubines who came to humiliate her. She set up a trap and killed someone with a borrowed knife, and initially established a reputation as a "poisonous concubine in the cold palace" to protect herself. In the mid-term, she relied on the "people's heart insight" skills and psychological knowledge rewarded by the system to accurately grasp the psychological weaknesses of each empress, prince and even courtiers during the concubine selection ceremony and festival banquets, and she could win over, alienate, or frame them, and weave intelligence networks and alliances invisibly. She and Chu Jinglan, a down-and-out prince who appeared to be a playboy but was actually sent as a hostage by the enemy, tested and used each other, and developed into an ally and lover who depended on each other for life and death.
In the later stage, the plot reversed, and Yu Wantang discovered that he was not the original person, but the real royal blood who was transferred to live among the people twenty years ago. The unjust case and the truth about the system all pointed to the mastermind behind the scenes - the powerful Queen Mother and the family that controlled the government. In the end, she united with Chu Jinglan and the loyal forces, and with the multiple promotions of the late emperor's edict, the system's ultimate mission, and her own strategy, she uncovered the conspiracy, brought down the black hands, and vindicated the unjust case. She chose to give up becoming a puppet empress, but instead worked with Chu Jinglan to reform the government, establish a new order, and truly take control of her own destiny. After the system mission was completed, she became the rule maker.
