Lin Wan, a poor student in the history department, was suddenly transported to the Jing Dynasty when he was flipping through ancient books in the library. When he opened his eyes, he saw that the house was leaking, the old servant was in tears, and he was forced by his evil relatives to be a concubine for the landlord.
But with two lifetimes of knowledge, how could she be willing to be manipulated? He used psychology to scare away evil slaves, used improved farm tools to grow life-saving vegetables, and used movable type printing to enable poor children to read. He also dared to break the shackles of etiquette and establish "Qingyun Girls' School" in an era when men were superior to women, teaching girls literacy and arithmetic and making a living.
Her freshness and sharpness caught the eyes of two men: one was the third prince Xiao Yu, who was idle on the outside but secretly scheming, who helped her overcome the store crisis and sacrificed his life to protect her during the coup, but always wrapped his sincerity with possessiveness; the other was Wen Jingran, the son of the prime minister who was as gentle as jade, obedient but not pedantic, who accompanied her to improve paper, helped her manage the court, and stayed with her for half her life as a "best friend".
From a vegetable stall on the outskirts of Beijing to debating politics in the court, from reversing the case of the original owner's father to getting involved in the imperial power struggle between the prince and the second prince, Lin Wan used modern wisdom to fight his way through the feudal quagmire. But when Xiao Yu pointed his sword at the world for her, Wen Jingran gave up his official career for her, when the smoke from the women's school hit the sword of the palace, she clutched the pen that came from time to time - should she choose the cold prince who could accompany her to seek prosperity, or the gentle and talented man who was willing to accompany her to stay ordinary?
