The ninjutsu developed by Onoki, the Third Tsuchikage of Iwagakure, "Earth Release: Added-Weight Rock Technique"!
The sand iron condensed by the Third Kazekage's puppet, combined with the enhancement of the Added-Weight Rock Technique, has extremely terrifying power.
After all, the weight of sand iron is heavier than ordinary sand. After being condensed into a block, its high density makes its weight even more terrifying. After being equipped with the Added-Weight Rock Technique without affecting its flexibility, its destructive power becomes exceptionally dreadful.
Kakuzu, who had already sensed the threat of the black iron spear, had a drastic change in expression.
Sand iron of this level cannot be completely melted by flames.
Moreover, its speed is so fast that the flames probably won't have time to burn it before it pierces through the encirclement.
Kakuzu no longer held back. All the seams on his body split open, and countless writhing black threads surged out of his body, enveloping him. At the same time, two masks fell from his back.
The mask representing the water-attribute heart and the mask representing the earth-attribute heart, under the support of the black threads, became two special monsters, separating from Kakuzu's body and standing on either side of him.
Under the distorted black threads, chakra surged rapidly.
"Earth Release! Earth Spear!"
The earth-attribute Earth Grudge Fear mask opened its mouth, and the ground swelled, separating several earth spears that crashed into the black iron spear.
However, the originally solid and sharp earth spears appeared somewhat too fragile against the black iron spear at this moment, and were directly shattered after only slightly hindering it.
On the other side, almost simultaneously, the water-attribute Earth Grudge Fear also opened its mouth.
"Water Release! Water Encampment Wall!"
A jet of water shot out from the mask's mouth, and a torrent of surging water gushed out.
Although it still couldn't stop the black iron spear, it further slowed down the black iron spear's offensive.
At the same time, Kakuzu lightly tapped the ground with his feet, quickly retreating and widening the distance again, giving himself enough buffer time.
"Lightning Release! False Darkness!"
Taking advantage of the water stains on the black iron spear and the metal's inherent conductivity of electricity, several bolts of lightning shot out.
Strands of lightning lingered on the black iron spear.
Immediately afterward, he suddenly pulled his hands downward, and the magnetized black iron spear was forcibly redirected under the guidance of the electric current.
Boom! Boom! Boom!
Although it seemed like Kakuzu did a lot, all of this was actually completed in the blink of an eye.
Kakuzu, who could simultaneously control five hearts of different attributes and perform ninjutsu at the same time, quickly conceived a countermeasure.
In the midst of the huge roar, the terrifying destructive power directly caused the ground to swell and crack, and a large amount of dust billowed up, obscuring the line of sight.
Qifeng stood still, his Byakugan still activated.
He could see very clearly that although this attack caused a great commotion, Kakuzu's repeated obstruction and alteration of the black iron spear's offensive and trajectory caused a certain deviation in the attack.
And for powerhouses like them, the slight deviation resulted in an ineffective attack.
Kakuzu was fine.
Qifeng was very clear about this.
"As expected, experienced ninjas like Kakuzu may seem to lack countermeasures, but their ability to seize opportunities is very strong, and they analyze the battle situation very clearly. Now that not even one of his hearts has been destroyed, it's too difficult to kill him, and the gains and losses are completely disproportionate," Qifeng thought secretly.
In the original story, Kakashi and the others also spent a lot of effort, plus a lot of calculations and ambushes, to destroy two of Kakuzu's hearts. Among them, even Hidan's almost certainly fatal "Evil God Ritual" was used to destroy one heart.
If it weren't for Naruto Uzumaki's accelerated completion of the wind-attribute chakra nature transformation, combining the Rasengan to develop the S-rank forbidden technique "Wind Release: Rasenshuriken," which destroyed Kakuzu's other two hearts in one fell swoop, Kakuzu, with his tattered body, was caught off guard and had his last heart destroyed by Kakashi.
Only under such circumstances was Kakuzu finally killed.
If there were some suitable ninjas around to replenish his hearts in time, I'm afraid Kakuzu could have survived even in that situation.
"It's good that he's not dead, so I can test my strength to my heart's content," Qifeng muttered to himself.
Taking advantage of the dust not having completely settled, he drove the Third Kazekage's puppet into the thick rolling dust.
"Wind Release! Pressure Damage!"
A stern shout rang out from deep within the dust, and the thick dust was instantly blown away.
Qifeng could be unaffected by the obstruction of vision, but Kakuzu couldn't.
"Continuing..."
Qifeng's fingers continued to move.
"Magnet Release! Sand Iron World Method!"
The black iron spear that had sunk into the ground once again dispersed into fine sand iron, gathering around the Third Kazekage's puppet flying in mid-air.
The sand iron rapidly contracted.
Under the pressure of the magnetic force, the large sand iron black cloud condensed into a ball, and under continuous pressure, it emitted a harsh metallic friction sound.
This caught Kakuzu's attention.
Seeming to have thought of what he might face, Kakuzu's eyes narrowed, and he wanted to launch an attack first.
He had a premonition that if he allowed this accumulated ninjutsu to be used, he would be in very big trouble.
But in the next second, before he could make a preemptive move, the squeezed black iron ball finally compressed to the extreme.
Like a hedgehog unfolding, countless spikes protruded from the black iron ball.
In a fraction of a second, these spikes transformed into large spikes with long thorns, sweeping across the ground very densely, forming a barrier covering an area.
Moreover, once the sand iron spikes landed, they would instantly retract, and then protrude again in the next breath.
Boom! Boom! Boom...
Almost endlessly, any place within the range of the cage barrier was completely destroyed.
The ground was shattered layer by layer.
Kakuzu under the barrier had no chance to counterattack at all, and simply dodging almost used all of his energy.
Not only that, the Third Kazekage's puppet could freely shuttle through the sand iron barrier and consciously control the sand iron spikes to concentrate their attacks on Kakuzu.
This is the Third Kazekage's strongest form in terms of attack, range restriction, and density.
Scars appeared on Kakuzu's body, and a large number of black threads were also severed under the attack.
