The Yunyi Country is not a country with slavery, it doesn't have slave marks, but it does have sin marks.
Sin marks are similar in meaning to slave marks, but while slave marks are used to distinguish slaves, sin marks are used to distinguish criminals.
Anyone branded with a sin mark is not permitted to hold any official or noble title. Even if they marry into nobility, their status remains at the lowest level, even lower than the maids in the household.
In other words, as long as Yin Ling is branded with a sin mark, no matter how much the Duke favors her, she won't have the right to command any servant.
In a strict sense, anyone in the Duke Mansion could order her around.
"No, no! Empress! Spare me! Princess!! I won't dare anymore!!!"
"How insolent! In front of the Empress and the Princess, a mere concubine dares to call herself 'I'!"
The nanny beside the Empress rushed up again and gave Yin Ling a few slaps, making Yin Ling's face visibly swell.
