After the Humble Palace Maid Was Reborn, She Relied on Her Good Pregnancy Physique to Counterattack

[Rebirth + palace fighting + childbirth and promotion + low-level counterattack + late-stage exclusive favor] Jiang Tan was originally the lowest-ranking maid in Fengyi Palace. The queen had been childless for many years, so she was chosen to be put on the dragon bed, hoping to use her belly to give birth to a prince. In his previous life, Jiang Tan believed in the queen's mercy. She endured the humiliation, struggled to conceive, and gave birth to the prince with all her might. But as soon as the child landed, he was taken away by the queen. And she was just waiting for a bowl of fatal medicine. When she opened her eyes again, she was back to before everything started. In this life, Jiang Tan is still involved. She knew she couldn't escape, so she didn't escape. She wanted to be favored, to get pregnant, to give birth to a prince, and to have the child only recognize her as his mother-in-law. From a palace maid to a talented person, from a nobleman to a noble concubine. The queen took advantage of her, and she took advantage of her situation. If the harem harms the fetus, she will kill him in return. The emperor initially only protected his heir, but later he protected her step by step. Everyone thought she was just a pawn raised by the palace. Until she held the emperor's eldest son and sat on the throne of the imperial concubine. Jiang Tan just let everyone know: a borrowed chess piece can also overturn the chessboard with his own hands.
