The principle behind [Ten-Finger Bullet] was not complicated.
Though Kaguya Black Bone had seemed to steal Deidara's line just now, the principle behind this move was vastly different from Explosion Release.
When Araki saw that Kaguya Black Bone could carve spiral grooves into his bone bullets to increase their power, he immediately thought of another highly destructive type of bullet—
—Dum-dum Bullet!
It was a powerful special bullet banned in modern military use, commonly known as an "expanding bullet," "fragmentation bullet," or even an "explosive bullet."
Why was it banned?
Simply put, it was too powerful. Due to its specially designed tip, after striking a human body, a dum-dum bullet deformed and fragmented, creating spiraling, tearing wounds—the so-called "expansion."
This kind of bullet did not penetrate the body. Instead, its purpose was to leave more bullet fragments inside, creating a funnel-shaped wound that was small at the entrance and large within. Moreover, the toxic lead core caused extremely severe damage to the target.
So basically, no matter where someone was hit, they were pretty much done for.
[Ten-Finger Bullet] borrowed that principle.
Kaguya Black Bone had modified the structure of his bone bullets according to Araki's description. Since he could also exert a slight degree of control over the bones after firing them, exactly when they exploded could be manually controlled.
Compared to dum-dum bullets, aside from lacking a toxic lead core, they surpassed them in flexibility.
"Hahaha, now you know how awesome I am, purple-haired brat!"
Seeing that he had injured his opponent with a casual move, Kaguya Black Bone's grin turned even more unrestrained as he flung another [Ten-Finger Bullet] at him.
Since you can't handle this move, sorry, but I'm going to beat you to death with it!
Whoosh, whoosh, whoosh!
The bone bullets tore through the
