When she looked up, she saw Ning Huaixiu staring at her in shock and disbelief, so she asked, "How much more do you have?"
Ning Huaixiu blushed and said hesitantly, "Just one more book."
Cai Wei nodded and said, "Not bad, go back and have dinner first, come back tomorrow!"
Ning Huaixiu hurriedly stood up and bid her farewell, "Yes, this servant takes her leave!" After taking a few steps, she couldn’t suppress her curiosity and stopped to ask, "This servant dares to ask Your Highness, what method do you use to calculate the accounts so quickly?"
Cai Wei was leisurely sipping her tea and replied unhurriedly, "Arabic numerals arithmetic!"
"Arabic numerals arithmetic?"
Ning Huaixiu was taken aback. Although she considered herself widely read and well-informed, how had she never heard of this method of accounting using Arabic numerals in this world?
Cai Wei put down her teacup and explained softly, "This arithmetic method was uniquely created by my father. It’s much faster and more convenient than the usual methods of accounting, and it’s about to be widely promoted throughout the Great Jin Nation. You’ll know it by then!"
Upon hearing this, Ning Huaixiu’s expression turned somber. So, it wasn’t just her looks but her abilities too that were inferior to her...
During dinner, Nangong Yi told Cai Wei about Duke Li Guo’s visit and his reply. Cai Wei was very satisfied with Nangong Yi’s democratic approach, letting Xiang Yun decide her own destiny, believing only then she could attain the happiness she desired.
