The Gray Ruins at the End of the World

A catastrophe swept the world, killing most people, first a plague, then a natural disaster. Just as people are preparing to concentrate their efforts to fight against this catastrophe, the world is undergoing drastic changes—— The West has discovered that a large number of high-level figures have died, and the power gap has led to riots at the bottom; researchers in various countries' research institutes have been killed one after another, and a large number of cutting-edge projects have been forced to terminate research... People have discovered a problem-the deceased are all men! Society seems to have pressed the pause button, and the world is falling apart. As seen from space, new lights disappear on Earth every day. A year later, a collective amniotic fluid embolism occurred in the obstetrics and gynecology department of a hospital in China. Since then, for every newborn born, a mother has died as a result. Civilization dies quietly. There are no nuclear explosions or zombies. The earth is still spinning as always, bringing about the most desperate ending in the most bland way - species extinction. This time, humans only!
