Bearing Heirs to the Throne

In the harem, all the children were born feeble-minded, including my eldest prince. Only Princess Grace, daughter of Noble Consort Samford, was an exception and was showered with love. Yet, she drowned my son during his first birthday banquet and forced me to drink poison. Upon reopening my eyes, I found myself bound to a Miraculous Pregnancy System, which allowed me to customize my children's intelligence and gender. In this new life, I am determined to fill the imperial palace with prodigies of my own making.
