(No romance, female-oriented, focused on family affection and saving Li Chengqian)
In this new story, Lin Wei, a modern soul, is reborn as Wu Yue, the youngest daughter of the Changsun family in the Tang dynasty. She hopes to keep a low profile, but it's hard to hide her knowledge of another world.
When the princes struggle with their studies, she cleverly weaves new learning into her book, A New Compilation of Mengqiu, unexpectedly becoming a "wild card" in the palace. When a severe drought strikes Guanzhong, she risks her life to send in a proposal to provide relief through public works. It eases the disaster, but also draws Taizong's inquisitive gaze.
Using anecdotes from ancient books as a cover, she quietly introduces modern ideas, from methods of providing relief to plans for imperial highways. Little by little, her proposals begin to take shape. But the emperor's scrutiny, the undercurrents in the palace, and other people's suspicions about her "miscellaneous books" have already ensnared her.
Now that her secret hangs over her like a sword, can this pawn from another world find a secure place in the Tang dynasty?
