Yi Siha, a eunuch serving Feiyan Palace, visits Ye Ming Palace. He has seen the ghost of a boy holding a blue swallow feather and asks Shouxue to help him. During her investigation, Shouxue comes across Yi Siha being caned by some older eunuchs. When she stops the punishment, Yi Siha's mentor Kang Lan trembles with fear. In Shouxue's eyes he saw a horrifying monster.
A feather from the blue swallow
 that died back then.
ريشةٌ من السنونو الأزرق
الذي مات آنذاك
Eine Feder von der blauen Schwalbe,
die damals starb.
Es la pluma de la golondrina que murió.
Es la pluma de la golondrina que murió.
Elle était à la pauvre hirondelle.
उस समय जो नीली अबाबील मरी थी
 उसका ही एक पंख है।
È la piuma della rondine
che morì nella trappola.
A pena da andorinha
que morreu aquele dia.
Перо той самой синей ласточки.
