well ... Gu Xin mimicked Lu Zheng and touched her chin. I've been reading Ren Ren's novels recently. It's about investigating a case. If one had to say what purpose he had, it would be that the Duke Zhengguo's mansion was easier to manipulate than the Yi and Yun families. Or rather, King qu has something on the Duke Zhengguo's mansion."
"Right, a handle!" Gu Xin's eyes suddenly lit up, " I've heard about Auntie Jia from great-grandma. Great-grandma said that in the beginning, aunty Jia and the country guarding Duke had a good relationship, which made many people in the capital envious. This was because the country guarding Duke was one of the most handsome men in the capital, and he had a good family background. He was very good to little Auntie Jia, and his reputation had even spread to the palace. At that time, great-grandmother had to teach uncle Emperor how to deal with some court officials, so she had a better understanding of the relationships between the families."
