The Emperor Has No Heirs? I’m So Fertile I Rule the Harem

【Rebirth revenge fantasy + devoted love later on + clear-headed heroine throughout】 In her previous life, Su Yue was blessed with extraordinary fertility, but her elder half-sister plotted against her. Su Yue had her tongue cut out and was imprisoned for seven years, reduced to a surrogate for her sister. Her three sons became stepping stones for Su Yao to become empress, while her swaddled daughter was turned into a secret fertility elixir. Su Yue, too, died at Su Yao's hands in despair, never escaping the underground chamber where she had been imprisoned for seven years. Reborn, Su Yue used her ability to bear children as bait to hook the emperor. They said her birth was too lowly? Then she'd win favor by bearing his children and claim the empress's throne! Her elder sister wanted to use her as a surrogate? Then she could hardly blame Su Yue for flaunting her favor and using her pregnancy to put her in her place! Su Yue calculated every move and planned ahead. The four children she'd lost in her previous life were born one after another. Her eldest son became crown prince, her second son commanded the army, her third son managed the court, and her youngest daughter was blessed with heaven's favor and saved the people... Even the emperor, who had once cared only about producing heirs, became obsessed with her, blocking her bedside night after night. “Yueyue, who's more important, the little ones or me?” “But Your Majesty said we needed to have lots of children and strengthen the imperial family.” “I'm done having children! If we have any more, I'll lose your favor!”
