In the small pouch, Anji noticed a hairpin. It was a plain accessory that Liu Guiya mentioned was commonly worn by the palace servants.
"However, we noticed that most of the servants wearing this hairpin act weirdly. They often lose memories of what they are doing, even when we have full evidence that they were trying to send secret letters to leak information. Moreover, a good number of those incidents happen at night. The imperial doctors have diagnosed it as a sleepwalking disorder, but I suspect that is not the case. There are faint traces of spell carvings on these hair accessories, but I don't recognise them."
