Gu Yihan frowned and thought for a moment. "Is Baby Nuo referring to maps?"
Map recorded the entire country's mountains, rivers, cities, towns, and lands.
Usually, only the ruler of a country would have the most detailed map. Some of the more detailed local maps were kept in the hands of the local prefectural governor.
It was also considered a kind of military secret, avoiding the possibility of having wily people from other countries stealing the map and taking the opportunity to study the routes to attack their country.
This shouldn't be something that was within Gu Nuo'er's understanding and knowledge.
Therefore, Gu Yihan was very surprised when she suddenly mentioned it.
"Where did Baby Nuo find out about maps from?"
The child looked up, her eyes as big as ice jade grapes.
