"The most basic use of sword force is to incorporate the majestic might of nature's mountains and rivers into your swordsmanship, layering the power of a single strike and driving it forward in successive waves, making it difficult to block."
With a turn of his raised hand, Hatake Sakumo shattered all the flames Uchiha Gen had unleashed. Amid the swirling lightning, he drew his ninja blade back and spoke.
Seizing the opening as Hatake Sakumo drew his blade inward, Uchiha Gen stomped down and lunged forward, fierce flames blazing along Demon Blade Thousand Blades as he slashed diagonally upward.
The familiar Leaping Sword Flame!
Flames surged up along the blade, becoming a towering wave of fire that rushed straight at Hatake Sakumo's face.
Uchiha-style Fire Release Ninja Sword Technique!
Hatake Sakumo calmly held his blade across his body to block. Thunderclap sword force covered the short blade, and with a turn of his wrist, the pale blue lightning on it instantly condensed into a thick barrier.
"A slightly stronger use is to turn this 'force' into something like chakra that you can wield. This lets you perform moves similar to ninjutsu, but... this use is only slightly stronger."
As the lightning became a barrier, Hatake Sakumo spoke again.
He was demonstrating to Uchiha Gen what sword force was, and how to use it.
The wave of fire from Leaping Sword Flame struck the lightning barrier. Searing heat and electrical power ate away at each other, red and white light flickering together as vast clouds of white-hot vapor rose.
"And the strongest use of sword force... no, I'd rather call it the most correct use, is..."
As the hot vapor rose, Hatake Sakumo's quiet murmur rang out.
The next instant!
Boom!!!!!
The sky abruptly darkened, and a deafening peal of thunder
