Su Xinyi received the message from Zhu Chanyi on the second day and felt slightly reassured. With Duke Zheng taking action, it wouldn't be too difficult for Yan Qiongsi to conduct a thorough investigation.
Mrs. Jiang on the other hand...
Su Xinyi hesitated over whether to send a message there. She sat in the hall, deep in thought. The matter implicated Prince Rong, who had the Empress backing him, and the Empress was currently protecting Yan Qiongsi.
After much deliberation, she couldn't directly reveal anything from Duke Zheng's side, but she still needed to give Mrs. Jiang a heads-up.
Having both parties take action was fine, but it would be problematic if they worked at cross purposes.
Su Xinyi called for Cuique and said to her, "You go make a trip to the Jiang Family."
Mrs. Jiang was a clever woman. With just a hint from Su Xinyi's side, she would know how to proceed.
Upon hearing the Crown Princess's orders, Cuique nodded repeatedly, "This servant will go at once."
