A fact was well-known about the mantis. In rare cases, the female mantis would cut the male mantis into pieces and eat it clean. Other beings that had the same habit of harming their male mates included the black widow spider and poisonous human widows.
There was no need to say much about the spider, but there was a story about the poisonous widow.
Once upon a time, there was a woman who had been married many times but became a widow each time. With the savings of her dead husbands, she thus snowballed her wealth. At the beginning of the story, she was just a widow who had just lost her husband. And at the end of the story, she was still a widow.
The poisonous widow would become a new widow by "marrying another rich man" and "poisoning her husband". With this cycle, she accumulated assets through the lives of others.
