In the past hundred years, "monsters" have been rampant. Scientists have discovered that male Alpha's body contains some energy that can summon spiritual beasts, and can defeat monsters with training. As a result, with the accumulation of a large number of nutritional supplements, scientific methods, radiation, and expectations, the probability of men becoming Aphla has skyrocketed. Female sexual characteristics gradually degenerate under drug extraction. Almost all babies will be subjected to this process to "extract AI factors", which is one of the cells necessary to differentiate into A. As a result, female Alphas were almost artificially destroyed, and female exorcists were even rarer.
