Summary
To solve the problem of baby girls cycling through reincarnation too quickly, the underworld changed the rules.
Infant spirits and parents could now choose each other.
From then on, every newlywed couple had a boy on the first try. Couples who had struggled with infertility for years finally got their sons. Couples with eight daughters asked for a son—and got one.
Boys packed every street and alley, thick as weeds.
