북검전기

When the world was plunged into darkness martial artists gathered to form the ‘Northern Heavenly Sect’.
With the help of the Northern Heavenly Sect people began to enjoy peace again.
However, as time passed the martial artists began to conspire against the ‘Northern Heavenly Sect’,
and eventually caused the death of the Sect Leader, Jin Kwan-Ho, destroying the sect with it.
As everyone left the sect, Jin Kwan-Ho’s only son, Jin Mu-Won was left behind.
Mu-Won has never learned martial arts, but he finds the Techniques secretly left
behind by his father and begins to acquire the martial arts of the Northern Heavenly Sect.
