Quick Transmigration: The Beauty Is Blessed with Fertility

[Quick transmigration + Childbearing System + stunning heroine + exclusive devotion + a touch of palace intrigue] (The male lead and heroine both have past relationships. If that bothers you, please skip this one.) Su Su was the top performer at the Quick Transmigration Bureau. She had just woken from her stasis pod, ready to enjoy a few months of well-earned vacation, when the bureau's newly arrived Childbearing System bound itself to her. Worlds: [An emperor who plays the pig to eat the tiger × an ambitious imperial consort plotting to seize power] The heroine is born into a position of privilege, and there's a little more palace intrigue than in the other stories. [A fearsome, heirless emperor of the modern era × a female general disguised as a man] The male lead is a master of the succession struggle. He ultimately wins by killing all his brothers in one fell swoop. The heroine initially disguises herself as a man. The male lead is ambitious, but even more devoted to her. The highlight is that he is ruthless and says little: anyone with designs on the heroine is killed outright. Palace intrigue plays only a small part. Skip this if you dislike the woman-disguised-as-a-man trope. [An emperor without heirs, devoted to cultivating immortality × a swindling, orphaned female Daoist] The heroine is one final tribulation away from ascending to immortality, but her master tells her to enter the palace as a consort. Entering the palace is one thing, but who knew that her master's idea of helping the emperor would mean making a chaste Daoist nun have his child? The highlight is that the emperor initially mistakes the heroine for an immortal, then gradually falls in love with her. [A blunt, straight-talking steppe khan with few heirs × an unloved princess sent to marry into the kingdom that conquered her homeland] The male lead is strong, and the heroine is a pitiful little thing. Skip this if that bothers you. [A charming, amorous regent without an heir × a stunning, discarded consort from the previous dynasty] The male lead is a playboy, and the heroine was sent to the Cold Palace by the current Empress Dowager.
