It referred to an incident in Zhang Xu Kingdom.
Many decades ago, wars were still raging on worse than it was now. It was simply relatively stable because each kingdom was busy because of their internal problem. They didn't have time to care for others and only tried to have some skirmish at the border because of some reasons.
The Lin Family was suddenly hit when they were already declining and the reason for their downfall was because of a young lady who leaked the information. That woman earned a large amount of fortune and then married away to Fei Yang Kingdom.
Because of the distance, Lin Family couldn't do anything.
They could only suffer in silence as things continued to turn worse. In order to make sure things would not repeat, the rebellious women children were forced to eat parasites who would only be forced out when they were about to be married away.
