Yin and Ning begin traveling towards the rebel base in order to meet Mo Heng, the man developing a new weapon.
Meanwhile, in the Taibai Empire, Construct Commander Meng Ji makes the decision to begin mass-producing the new model of construct. Zhao insists the new model is still a prototype and opposes its mass-production, but Commander Meng Ji claims they must hurry in order to conquer the world. Upon hearing their arguments, Empress Cheng also orders the mass-production of constructs.
Zhao leaves his underlings to look after matters at the Construct Palace while he departs with the mobile unit in search of the magic-using rebels he fought previously.
Why do people always look 
back as they walk forward?
لمَ ينظر الناس للوراء بينما يمشون للأمام دوماً؟
Wieso blickt der Mensch stets zurück,
sobald er voranschreitet?
¿Por qué todos miran atrás
mientras caminan hacia delante?
¿Por qué todos miran atrás
mientras caminan hacia delante?
Pourquoi avancent-ils
le regard fixé vers le passé ?
Perché le persone guardano sempre indietro 
mentre vanno avanti?
Por que as pessoas sempre olham
para trás mesmo andando em frente?
Почему мы идём, вечно оглядываясь назад?
