He used the Gravity Sphere held in Naruto's right hand as the template for duplication!
His left hand hovered over his left eye. Through the gaps between his fingers, his Rinnegan swept across the sky, placing the duplicated Gravity Spheres throughout it!
Of course, there was a limit to how far he could place them.
Regardless of the object's size, the maximum range extended three hundred meters outward from its edges. Placement relied on sight, so it could not pass through anything that obstructed his vision!
Thus, Naruto placed them from the outside inward, from far to near...
In mere seconds, the space within a three-hundred-meter radius was packed solid with tens of thousands of Gravity Cores for Planetary Devastation!
Looking down at the dense black mass below, Madara laughed. "Hahahahaha! It looks like a big bowl of caviar..."

He formed a hand seal with one hand, scattering the tens of thousands of Gravity Spheres throughout the sky...
Whoosh! The Gravity Sphere serving as his template vanished from his palm.
"Whew..." Naruto drew a deep breath and pressed his palms together.
-Ōmononushi Style: Planetary Devastation: Great Daikokuten!

"Ahahahahaha! This is insane, insane!!!"
Amid Madara's wild laughter, Susanoo swung both swords through the air, unleashing a chain of slashes powerful enough to shatter all things in nature. In an instant, it destroyed dozens of Gravity Spheres!
But compared to their total number, that was a mere drop
