Cang Yue traveled to a world of female supremacy. In this world, girls did not need boys to give birth to offspring, so boys were eliminated. All boys in this world must take progesterone. After taking progesterone for 18 years, a boy can change from a boy to a girl. If a boy refuses to take progesterone, the state agency has the power to send the boy to a training school for girls. Women's training centers violently force boys to take or inject progesterone.
