In her previous life, Shen Lingyi was the head of the "Dark Pavilion" of the Jianghu intelligence organization. She held the world's secrets but died in a power struggle. She was reborn as a concubine in the Hou family and was forced to enter the palace draft. While other concubines are still fighting for favor with tears and scheming, she has rebuilt an intelligence network and has everyone's fatal clues. From a talented person to a concubine to a queen, she and the young emperor went from an interest alliance to a life-or-death agreement. They teamed up to bring down the relatives, eradicate the masterminds behind the scenes, and finally abolished the draft and established monogamy, becoming a legend of a generation of virtuous queens.
