Su Jingshu, a 31-year-old modern urban white-collar woman, is a senior fan of palace dramas, especially the plot of "The Legend of Zhen Huan". She was accidentally electrocuted while watching a TV series on N, and her soul traveled to the scene of the Zhen Huan Chuan draft in the first year of Yongzheng's reign, and became the show girl who was about to participate in the draft - the daughter of Jeju leader Shen Zishan and the distant cousin of Shen Meizhuang, named Shen Jingshu. With her omniscient perspective on the plot, modern thinking wisdom, and carefully maintained dignified beauty, Jing Shu is determined to use this once-in-a-lifetime opportunity to survive in this turbulent harem, and step by step to the top of power, taking charge of the Queen's Phoenix Seal.
She is well aware that the harem is dangerous and every step she takes is like walking on thin ice. From his first appearance in the draft, to his careful observation when he first entered the court; from cleverly avoiding Concubine Hua's sharp edges and traps, to secretly making trustworthy people; from using information gaps to predict the development of events, to carefully planning to guide others to his own advantage. As "Shen Jingshu", she will deal with many characters such as Emperor Yongzheng, Queen Yixiu, Concubine Hua Nian Shilan, Zhen Huan, An Lingrong, Shen Meizhuang and so on. She will obtain the Sacred Heart earlier than Zhen Huan, know how to manipulate the emperor's thoughts better than Concubine Hua, and be better at hiding and planning than the Queen. She will experience frame-up and counter-attack, favor and frustration, alliance and betrayal, and eventually defeat all her opponents - including Zhen Huan at her peak, the domineering Concubine Hua, and the sinister Queen one by one, to achieve her ultimate goal of being the mother of the world. This is the ultimate test of wisdom, strategy, character and desire.
