A fierce battle between two of the finest warriors from the Joseon Dynasty and Qing Dynasty unfolds.

2. The philosophy behind the arrows [source]

• Nam-yi's arrows: Only 1/3 of the traditional arrow size and weight, making it superior in velocity, force, and range. His arrows make it hard to detect the shooter's location, thus ideal for an ambush.
• Jyu Shin-ta's arrows: 24 times heavier than the traditional arrow, tearing apart targets with just one shot.
• The bow-and-arrows in action scenes will keep you in awe and you will have that heart-in-throat kind of feeling throughout the entire movie.

3. The usage of the Manchu language [source]

• Director Kim Han-min introduces the Manchu language in order to portray a more realistic historical depiction of the 'Manchu War of 1636'.
• Due to constant practice and learning, the actors were able to speak Manchu at a level not seen since the actual days of the Qing Dynasty. The heavy, masculine tone that the Manchu language exudes is especially well-carried out by Ryoo Seung-yong who acts as Jyu Shin-ta, a Manchu warrior.
  
• The persistent efforts that both actors and film crew alike made to stay true to the Manchu language surely lends in favor of the movie's overall depiction of this period in history.

You really, really must watch this movie. Its impressive action sequences and historical details plus the few factors listed above will make you feel like you have stepped back in time to witness history for yourselves.
