Yun Jiao said, "Since there are no issues with these, it's very likely the problem lies in the diet. It's best to carefully investigate what Duke Guo consumes daily."
The head maid curtsied and exited.
The next day, Yun Jiao went to pay her respects to Lady Wu, who held her hand and said, "Yesterday, I had people investigate thoroughly, but couldn't find anything. I want you to take a look."
With a wave of Lady Wu's hand, the maidservants laid out several items.
There were the tea leaves that Duke Guo regularly drank, several kinds of wine he often consumed, and the candles used in his room.
Yun Jiao inspected each item and then shook her head, "No problem, there's nothing wrong with any of them."
She thought for a moment, "It seems very difficult to find anything now. After all, who knows what Duke Guo has eaten or drunk over the past ten years."
