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.
The guilt spun by a small lie becomes 
the seed of a series of tragedies.
الذنب الذي زرعته كذبة صغيرة يصبح
ثمرة سلسلة من المآسي
Aus einer kleinen Lüge
entstand eine Schuld,
La culpa por una pequeña mentira
La culpa por una pequeña mentira
Il senso di colpa per una piccola bugia
A culpa criada por uma pequena mentira
vira a semente de uma série de tragédias.
Маленькая ложь становится истоком
множества трагедий.
