Three years ago, Yin, and Zhao lived together in a nomad settlement. The three of them were close childhood friends.
The sisters loved Zhao like a brother, but that eventually turned into romantic love.
While playing in the field as usual, they discover a broken construct.
Zhao is drawn to the workings of the strange machine.
Meanwhile, in the Taibai Empire, Chief Engineer Mo Heng is working on Zhengtian, the ultimate weapon.
We invented constructs and sent 
our forces further abroad,
ابتكرنا المُركَّبات وأرسلنا جيوشنا مسافات أبعد خارجاً
Wir erfanden die Konstrukte
und entsandten unsere Truppen in die Ferne,
Inventamos los constructos
Inventamos los constructos
On a développé les bêtes mécaniques,
envoyé nos soldats au loin
Abbiamo inventato i costrutti
Nós inventamos armamentos e mandamos
as forças ainda mais para longe
Мы изобрели конструкты и стали
отправлять войска всё дальше,
