Fire Release: Big Flame Bullet

This technique is a senjutsu altered version of the Fire Release: Flame Bullet. The user fills their mouth cavity with oil, created inside the body with senjutsu chakra. This oil is then expelled and at the same time ignited, which creates a giant flame, equivalent to multiple Flame Bullets. This flame can completely cut off the front escape route of an enemy cornered in a hallway or room, or it can thoroughly burn each respective escape route.
