Traveling entertainers Yin and Ning are very close sisters.
Yin cares for her armless sister as they travel between villages, putting on performances of swordplay and dancing.
When they arrive in the ruins of a village, they find a mysterious bamboo writing strip.
The strip glows, and from within it a strange girl and a single sword appear.
Meanwhile, in the Taibai Empire bent on conquering the Shenzhou region, a boy name Zhao is working as a slave.
Zhou, who has been teaching himself engineering, meets a young girl one night.
But now we won't have to camp out.
لكن لن يكون علينا النوم في الخلاء
Jetzt müssen wir zumindest
nicht draußen schlafen.
Pero ahora no tendremos
que dormir en la tienda.
Pero ahora no tendremos
que dormir en la tienda.
On n’aura pas à camper, au moins.
Perlomeno 
non dovremo accamparci all'aperto.
Mas agora não teremos que dormir na rua.
Зато ночевать будем 
не под открытым небом.
