"In order to keep humanity proliferating, they were only able to use gene modification to transform humans."
"Under such gene modification, there became more and more men and fewer and fewer women, leading to a male-to-female ratio of 100:1 on this high-tech Alliance planet, and original pure-blood females with high fertility have almost gone extinct."
"If they can't find an opportunity to improve the situation, then, as you might guess, this Union planet will become a place of only males and eventually go extinct in a number of years. No one on the entire Union planet wants to see this cruel outcome happen."
"Therefore, now if they discover a single original pure-blood female, they will treat her like a national treasure and nurture her to breed a new generation of pure-blood humans, hoping to regain the most primitive human fertility."
