My Fertility System Only Wants Babies, But I Want a Crown!

Died of old age, then dumped into the Dajing Dynasty as Shen Yao, a low-ranking concubine entering a dangerous imperial harem. Her appearance is average, her family useless, and the royal line is riddled with sickly heirs. She's cannon fodder, destined for a lonely, insignificant life. But Shen Yao isn't a meek maiden. She's bound to the Child-Bearing System, a bizarre entity focused solely on reproduction. While the system demands powerful offspring, Shen Yao, ever the opportunist, quickly abuses its \"offspring-enhancing\" pills for her own benefit—becoming stunningly beautiful, incredibly healthy, and utterly irresistible. Her goal? Not the emperor's fleeting favor, but to birth a uniquely healthy, high-potential royal heir who will secure her lavish, lazy future. In a palace where power is fragile and survival is brutal, can this selfish, pleasure-seeking concubine truly game the system, outwit her rivals, and casually raise the next Emperor, all while enjoying the good life?
