Sisters Yin and Ning are joined by rebel forces Yuezhi and Rou. When they are invited to join the rebel army, Ning enthusiastically agrees, but worried for her younger sister, Yin is opposed to the idea. Ning resists her sister's concern for her. Meanwhile, Zhao reveals his concerns to Empress Cheng. Since the day of the tragedy three years ago, he has been unable to sleep. Furthermore, he is unable to forget what he's seen. During the night, Zhao struggles with his memories of the tragedy, so Cheng begins showing him around the secret passages of the palace.
But if you don't sleep, 
you'll pay for it tomorrow.
لكن إن لم تنامي، ستدفعين الثمن غداً
Aber wenn du nicht schläfst,
rächt sich das nur morgen früh.
Pero si no duerme,
mañana estará cansada.
Pero si no duerme,
mañana estará cansada.
Tu seras fatiguée demain,
si tu ne dors pas.
Ma se non dorme, domani
 ne pagherà la conseguenze.
Mas se não dormir, vai
pagar por isso amanhã.
Лучше поспи, а то завтра аукнется.
