The Cross-dress warrior of Sun

In ancient China, when the Hun overthrow the dynasty,
A decree forbid any martial arts.
Hidden in the heart of the deepest mountains,
A school teaches those forbidden arts to a young generation of warriors.

Their goal is to free their land from their oppressors,
But to bring peace the have to maintain harmony in their own refuge.

Feng Yang is a young student of the Sun academy,
Dreaming of becoming a powerful warrior, her place in the academy is compromised when the son of the previous minister of war discover Yang's secret...

Because the martial art school is a place reserved for boys... and Yang is a girl.

Her real name is Feng Yue.
