Although Mrs. Zheng didn't feel a concubine-born girl was not worthy of her son.
Her son had lost his reproductive function due to Princess Fulu, so Qiao Ruoyi was suitable to be his wife now.
Early in the morning, Mrs. Zheng brought a matchmaker to the Duke Mansion with a mingy betrothal gift.
When she came to the gate, she was stopped by the guards of the Duke Mansion. "Mrs. Zheng, Madam has ordered us not to allow you to set foot in the Duke Mansion again. Please leave!"
Mrs. Zheng was puzzled and said, "Why? I'm her sister-in-law!"
Qiao Jinniang chuckled at Mrs. Zheng at the gate and said, "So what? The Zheng family murdered my sister and swapped her with your own daughter. We don't welcome a murderer.
"I'm going to sue you to the Chang'an Prefect. You Zheng family must take responsibility for murdering my sister."
Mrs. Zheng avoided eye contact with her and said, "Nonsense! I don't know what you're talking about."
