Shengyan died suddenly after working overtime and traveled through time to become the "last concubine" in the backyard of Xiao Han, Marquis of Dingbei in the Dajing Dynasty.
The original owner was the daughter of a declining scholarly family. She was sent to the Marquis Mansion in order to seek a way out for her family. She was not summoned for six months after entering the manor. She was treated harshly by the royal family and looked down upon by the servants. She was eventually taken over by Shengyan when she was about to die from cold and hunger.
The time travel is instantaneous and bound to the "Legendary Continuation System". The core mission of the system is to give birth to an heir for Xiao Han (either a concubine or a legitimate daughter). The mission successfully unlocks the "survival guarantee" (increased status, penalty-free privileges, and pregnancy protection). The ultimate mission is to give birth to a legitimate son who can be exchanged for "freedom".
