Chapter 442: Chapter 442 Punishment(1)_1

After a girl matures into a woman, she will have her first menstrual cycle. In Cai Wei's era, even children as young as eight to ten years old knew about this, yet Nangong Yi, the legitimate heir to the throne of the Great Jin Nation and His Highness, King Qin, truly had no idea that such a thing could happen to women!

Ever since he had become aware of his surroundings, he had been busy learning literature, military strategy, managing people, and how to evade the conspiracies and assassinations of Jin Guifei's party, and many other things that would be useful in the future.

The burden on him was too heavy. There were too many things to do and as a result, he had never devoted energy to observing women or exploring the differences between men and women.
