"Is this too valuable?" Yang Zhenshan said with shock after his initial reaction.
Zhou Lan smiled and said, "I was born in the Duke Ning Mansion."
Yang Zhenshan's expression stalled.
He did not know what the Duke Ning Mansion represented in Da Rong, but he did understand the meaning of a duke.
In Da Rong, the nobility was divided into dukes, marquises, and earls, spanning three levels and nine ranks, from a first-rank duke to a third-rank earl.
The titles were also divided into hereditary and non-hereditary, although generally, a duke was always hereditary; the highest non-hereditary title was that of a first-class marquis.
Being born in the Duke Ning Mansion meant Zhou Lan might be the daughter or granddaughter of Duke Ning.
Whether legitimate or not, such lineage was beyond what Yang Zhenshan could currently aspire to.
When Zhou Lan mentioned her background, it wasn't to elevate her own status, but rather to explain that her gratitude gift wasn't overly valuable.
