After Sheng Yan dies suddenly from overwork, she transmigrates into the body of a low-ranking concubine in the household of Xiao Han, Marquis Dingbei of the Great Jing dynasty.
The original owner was the daughter of a fallen scholarly family. Sent to the marquis's manor to save her family, she had spent six months there without being summoned, suffering mistreatment from the principal wife and contempt from the servants. At last, freezing and starving, she was near death when Sheng Yan took over her body.
The moment she transmigrates, she binds to the [Legitimate and Illegitimate Heirs System]. Its core mission is to bear children for Xiao Han, whether sons by concubines or legitimate daughters. Completing a mission unlocks survival benefits, including increased allowances, immunity from punishment, and protection during pregnancy. The ultimate mission is to bear a legitimate son and exchange him for her freedom.
