The concubine Shen Zhiyao once traveled through time, from being an abandoned son of the Hou family who was bullied, to becoming the only strange woman in the eyes of Emperor Xiao Jingyun who dared to speak out about the world's gains and losses. She used history as a sword to break up party disputes, uncover old cases, and quell border troubles, and gradually climbed to the top of power. She was framed by her eldest sister, framed by eunuchs, and seduced by concubines, all of which were her steps to ascend to heaven. And the cold-faced emperor looked on with cold eyes on the surface, but in fact he personally burned out all threats for her - being the only favorite was both a strategy and a redemption.
