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.
But since Mo Heng betrayed us,
 the Chief Engineer's seat has remained empty.
لكن بعد خيانة بوكو كو لنا، ظلّ منصب
كبير المهندسين شاغراً
Doch seit uns Mo Heng verraten hat,
ist diese Position unbekleidet.
Pero como Mo Heng nos traicionó,
el puesto de ingeniero jefe está vacante.
Pero como Mo Heng nos traicionó,
el puesto de ingeniero jefe está vacío.
Mais depuis la trahison de Mo Heng,
ce poste est vacant.
Ma da quando Mo Heng ci ha tradito,
il posto da ingegnere capo è rimasto vacante.
Mas como Mo Heng nos traiu, a vaga
de Chefe Engenheiro está vazia.
Но, с тех пор, как Мо Хен предал нас,
его место продолжает пустовать.
