The female emperor is the ruler of Great Qi during the story's timeframe. She is mentioned in relation to Chen Baishu's daring medical procedures, specifically when he proposed performing cranial surgery on her based on Qi He's joking suggestions. She merely laughed off the proposal and refused the surgery but did not punish Chen Baishu in any way, demonstrating a certain magnanimity. Her existence is noted as a source of terror for Qi He, who never dared speak carelessly in front of Chen Baishu again after this incident.
