You Were Supposed to Serve the Emperor in Bed and Bear His Child, So How Did You Charm Him and Steal the Phoenix Throne?

She used to dread spending the night with him. Later, she spent every night with him. Yun Xi once naively believed that her body, so fertile that she conceived whenever she was favored, was a gift from heaven. If she obediently took her elder sister's place in the imperial bed and bore a child, a peaceful life would surely follow. But when fireworks burst during the birthday banquet for the twins she had borne... She was handed over to a sadistic nobleman and tortured to death. Reborn, Yun Xi won't put up with it anymore! Need someone to bear a child for you? Then she'll go along with it and sleep with her imperial brother-in-law. Low status? She has her ways of getting His Majesty to change her name and family registration! The six palaces join forces to frame her? She'll take them on one by one. She'll never spare anyone who harms her. In this life, she won't be a pawn. She'll be the one moving the pieces. Wealth and glory? Supreme power? Twin children, a boy and a girl? She wants it all! But, Your Majesty, didn't you say you were a workaholic who loved the empire, not beautiful women? Why do you cling to her every night, refusing to let go, and insist on putting the Imperial Seal into her hands? “Empress, two children aren't enough. Have a few more with me?”
