I Became a Cannon-Fodder Concubine, and the Emperor Gave Me All His Tenderness

Shen Qingzhi, a modern woman, transmigrates overnight and becomes a powerless concubine-born daughter of the Shen family in the Great Jin. Her birth mother possessed a lost art of ancient mechanical engineering, but after becoming entangled in an old case from the previous dynasty and being framed by the Rong family, she died with regrets. All she left behind was a white jade longevity lock concealing a secret key and some incomplete mechanical blueprints. Seeking to curry favor with the powerful, the Shen family plans to send Qingzhi to marry the violent old prince as a good-luck bride. Just when she is at her most desperate, Emperor Xiao Che suddenly appears and takes her into the inner palace. It looks like salvation, but in truth, he is pushing her onto the game board.
