Tasked with investigating a ghostly woman dancing nightly on the palace walls, Maomao finds a sleepwalking Concubine Fuyou. But with no medicinal cure for sleepwalking, she's forced to dig deeper to find the real reason behind Fuyou's affliction.
And she appears every night 
at the eastern castle walls!
!وتظهر في كلِّ ليلةٍ على أسوار القلعة الشّرقيّة
Und das jede Nacht auf der Mauer am Osttor!
Il apparaîtrait tous les soirs
sur les remparts est !
Ho sentito anche che compare
ogni notte vicino al muro orientale.
E ela aparece toda noite,
nas paredes do portão leste do castelo!
Каждую ночь она появляется
 на восточной стене!
