Gu Youyou looked in the direction the voice had come from; by now, there was no sound at all—perhaps the person had already left.
She took a breath and, without changing her expression, said, "Catching cicadas!"
"Catching cicadas at night?" Jin Zijin asked skeptically, raising an eyebrow.
Gu Youyou responded earnestly, "Yes, at night. I can't climb trees, so I can't catch them during the day."
"If you can't climb trees, you'll catch even fewer at night."
"Then I'll collect cicada shells!"
"What do you want those for? They're disgustingly creepy," Jin Zijin said with a grimace.
"It's an ingredient for medicine, a good remedy for sickness," Gu Youyou explained.
Having been at Jisheng Hall for so long, she realized it was the season to collect cicada shells, yet she had not seen this ingredient in the medicine cabinet. This could only mean one thing: at this time, the use of cicada shells in medicine had not yet been conceptualized.
