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--
What if once we find the 
world beyond and conquer it,
ماذا لو وجدنا العالم وراءها وحكمناه
Was ist, wenn wir nun
eine Welt hinter jener finden?
¿Y si cuando lleguemos
al fin del mundo y lo conquistemos,
¿Y si cuando lleguemos
al fin del mundo y lo conquistemos,
Mais si après avoir conquis
le monde qu’on connaît,
E se, dopo aver scoperto e conquistato
 il mondo oltre confine,
E se quando encontrarmos o mundo
além daqui e o conquistarmos,
Что, если мы найдём,
что дальше мир не кончается?
