The doomsday imagination of wasteland pollution has appeared in human literature, but now, wasteland pollution has become a reality. It's just polluted wasteland, the breeding soil for human beings.
As technology develops and parthenogenesis becomes common, the characteristics of biological sex are gradually degenerating along with the decline of sexual reproduction.
At this time, large-scale parasitic pollution occurred that sent chills down people's spines - pollution like rain, known in history as "Xia Niang/Xia Daddy Day".
The words "father and mother" are taken from the names of human beings' roles during the stage of sexual reproduction when they are giving birth to newborns.
The difference is the time of knowing - humans who immediately know that they are becoming mothers and humans who do not yet know that they are becoming fathers are both parasitic targets of pollutants.
It started with regional rainfall pollution, and with the spread of unsuspecting humans, the scope of the pollution expanded faster.
Just like land pollution, contaminated human genes lose their fertility, and the recovery period lasts for several years or even until death. During this period, everything related to fertility is bred to be parasitic pollutants.
Parasitic pollutants are like alien shapes that remain in the history and culture of sexual reproduction. The pollution has lasted for ten years, and humans still do not know the source of the pollution.
Some people guess...

Purpose: Chasing a glimmer of hope in a hopeless life
