Fire Release: Dragon Fire Technique

The user breathes fire along a cord or any other type of long object, which rushes forward in straight line catching the enemy on fire. A line of enemies can be used as the conductor as well. The flames are meant to target, and assault the enemy's upper body just like a projectile weapon.

While the technique is shown in the anime to be even larger and more devastating than Fire Release: Great Fireball Technique (and being able to melt rock), in the manga it is shown to be just a small burst of flame running along a line of wire.
