Yin and Ning meet Tuoba Yuan and Can Lang during their travels.
They are members of the rebel forces fighting against the Taibai Empire and invite the sisters to join them. They claim it is the duty of one who possesses the tianshu and the Xuan Yuan Sword. Meanwhile, in the Taibai Empire, the recently promoted Zhao struggles with the development of new constructs. In order to give him a chance of pace, the  mpress Long Cheng assigns Zhao to command a unit of constructs and travel the empire. However--
The rebel forces' rise in power and Chief 
Engineer Mo Heng's betrayal make no sense.
صعود قوّة جيوش الثوّار وخيانة كبير المهندسين 
بوكو كو ليست منطقية
Die Rebellen werden immer stärker und
Mo Hengs Verrat will mir nicht einleuchten.
Las fuerzas rebeldes ganan poder,
Las fuerzas rebeldes ganan poder,
Entre la montée en puissance
des rebelles
L'aumento della potenza delle forze ribelli
O aumento de força das forças rebeldes e a traição
do Chefe Engenheiro Mo Heng não fazem sentido.
Мятежники набирают силу, а главный
инженер предаёт нас... Уму непостижимо.
