After two sleepless days and nights, Yan Lingzhen finally found the aphrodisiac gu insect.
This poisonous insect was used to cure male deficiencies, so it's no wonder the Deputy General had used it on himself.
He must have been newly under the influence of the gu and wanted to try it out on a palace maid.
"The gu must have been administered recently, or else we can't explain the Deputy General's erratic behavior," Yan Lingzhen, sitting amidst a pile of medical books, said to Xie Qun as he yawned.
Xie Qun, noticing the dark circles under her eyes, nodded in agreement, "Indeed, so anyone who appeared in your courtyard during that time is a suspect."
"That day, too many people showed up."
"The search range is wide, and we don't have much time left."
She couldn't help but yawn again and continued with her analysis.
Less than half a day remained until the three-day deadline.
