Painless motherhood + mindless cool writing + multiple male protagonists
The heroine is not a reproductive tool, so the plot of giving birth is relatively slow.
People with love brains and emotional mysophobia are not allowed to enter (love brains and zombies will not be eaten.)
In her previous life, Qian Huahua died of congenital heart disease at a young age. She thought everything would disappear after she died.
Unexpectedly, when she woke up again, she was transported to a graduate student with the same name as her on Blue Star in 2035. Fortunately, she survived and encountered the first scene of the end of the world.
When Qian Huahua was about to be eaten by zombies, the childbirth system suddenly appeared and saved her.
Qian Huahua, who was forced to be bound to the childbirth system, stared at the sky speechlessly. Other people's apocalyptic spaces, superpowers, and various skills were flying all over the sky, and she was so invincible that she was the only one who was asked by the system to have children every day.
Fortunately, this childbirth system is still a bit humane, allowing her to become a mother painlessly, and she will receive generous rewards after giving birth to a child.
As for whom to have a baby with, of course she has to find a man she likes!
