Emperor: "...Concubine Yu's body is itchy and covered in small red spots. What's going on?"
The Imperial Physician hurriedly replied: "I just discussed with several other physicians, and it seems that Concubine Yu is intolerant to certain foods."
"What intolerance?"
"It's an allergy," Jiang Ning casually explained.
The Imperial Physician looked at her and smiled, "Princess Consort used the right term. Your Majesty, some people do indeed have allergic reactions to specific foods. I heard that Concubine Yu ate shrimp, so it's likely she's allergic to seafood and shellfish. These foods can indeed cause itchy allergic reactions all over the body, and it's not just Concubine Yu."
"Has Concubine Yu never had shrimp before?" the Emperor asked.
Palace maid Chunxiao replied awkwardly, "As far as I remember, Her Highness has never eaten anything with shells before..."
The Emperor angrily said, "Why didn't you say so earlier?"
