The story takes place in the parallel world Earth in 2050. Because of America's super human experiment, new pansexual humans appeared in the world. Because of their good looks, high physical fitness, and sexual charm far exceeding that of men and women, they caused huge conflicts and changes not long after they entered society. In 2095, the Football League officially became the common supreme government of mankind. However, due to the dilution of the genes of pansexuals, the number of XY males gradually decreased, and the conflict finally broke out. After the global civil war in 2095, the radiation of antimatter and radioactive particles gradually reduced the number of XY males. To extinction, then men began to conceive, and the female uterus was gradually absorbed by the body. From then on, the earth was divided into four genders: male, YY, XYY, female, XX, XXY. Only double YY can conceive, and all those with X sex chromosomes can conceive. There are only two political powers in the world after the civil war, the Pan-Asian Federation (later the Eurasian, African-Australian Federation) where the heroine belongs, and the Gamiba Empire where the male protagonist belongs. In the 2230s, when the empire hoped to use war to divert domestic conflicts, she gave birth to six children at the age of twenty. The "heroic father" used surgery to pretend to be a helper and asked the emperor to allow him to sneak into the heroine's lover, the joint deputy speaker, steal secrets and influence decisions to restore the glory of the tsarist family. However, the development of things deviated from the track he expected from the beginning.
