The silver needle had been given to her by the Emperor before they left the Palace, saying that he wouldn't be able to look after her every step of the way on the journey, so she should test everything she eats with the silver needle and not eat anything indiscriminately.
If it wasn't for Nan Feng testing the oranges and peanuts with this silver needle that day, and then unwittingly eating so many different things, she wouldn't have had diarrhea.
After they finished eating, someone led them to gather with the Emperor.
This time, they were going to a county in the entire region called Cen County, which had always been a hard-hit area by floods in previous years. However, the land there was fertile, and crops grew easily, so the people were reluctant to move and had continued living there until now.
Once everyone had arrived, the Emperor stood in front and scanned the crowd.
Fortunately, all the ministers who were supposed to come had arrived, and so had Nan Feng.
