The Eldest Lady Is Upright and the Heroine Is Right

During the Yongle period of the Ming Dynasty, Shen Heng, a maid from the Huanyi Bureau, was born with a blue spot on her face as big as a copper coin and was regarded as an "unlucky person". She doesn't know her life experience, she only knows how to wash clothes, get beaten and take orders every day. Until one day, she was secretly taken away by an emissary from the East Factory and ordered to get close to the seriously ill young prince - because her blood could detoxify strange poisons. Only then did Shen Heng realize that his existence was involved in the game between the four major forces in the harem: the queen wanted to use her as a favor, the concubine wanted to use her to harm others, the eunuch in charge of the ceremony wanted her to be a puppet, and the seemingly fatuous Emperor Yongle already knew everything. She originally just wanted to survive, but she discovered step by step that her life experience, the birthmark on her face, and her natural medicinal blood were all the result of someone's careful design. And when she finally stood in the center of the chess game, she made a decision that no chess player had expected - to overturn the chess board and become the banker herself.
