A normal person's brain certainly couldn't handle such a large calculation, but Akira had two brains to rely on.
Moreover, his main body's brain had undergone two absorptions, merging the spiritual energy of four people, making its capacity even stronger.
With the enhanced capacity, the functions it could perform were also improved, so multitasking with three different tasks simultaneously was barely achievable.
Of course, the attention allocated to each side would be slightly reduced as a result.
Akira needed to concentrate on controlling the ten puppets fighting Chiyo.
Secondly, there was Ebizo. To fight this experienced ninja, a significant portion of his attention was also allocated to him.
Akira paid the least attention to the Sand ninja.
The iron sand attacking them seemed unpredictable, but in reality, it was moving in a repetitive pattern. One could discern it if they focused for a while.
This was because Akira couldn't truly multitask with three different tasks. Controlling the iron sand with regular movements didn't require too much attention.
It's like a person can't write different characters with two hands at the same time, but can continuously draw a simple pattern on one side while writing complex characters with the other.
At the beginning, Akira's iron sand weapons did cause some trouble for the Sand ninja.
But as time went on and they gradually adapted to the Iron Sand Formation, the Sand ninja began to be less frantic.
They used rudimentary lightning release to interfere with Akira's Magnet Release chakra, causing some of the iron sand weapons to break apart.
Akira had to inject chakra again to reactivate and control them, which not only increased chakra consumption but also required extra attention.
The situation gradually became unfavorable for Akira, but he wasn't in a hurry to retreat. He had shown up precisely to test the puppets' ultimate skills.
There was still a lot of chakra left within the Yin Seal, enough to leave himself enough chakra to escape at the end.
So, Akira accelerated the rhythm of his attacks, wielding the blades on both arms to continuously attack Ebizo's two puppets.
Ebizo's puppets countered with their own weapons, the blades colliding and creating sparks.
The puppet clone used Magnet Release to control its body, spinning rapidly.
The entire body spun into a top, and the two spiral blades also spun, creating even greater destructive power under the body's drive, instantly damaging Ebizo's two puppets.
This frightened Ebizo, who quickly recalled the puppets.
His three puppets were damaged during the last battle with Might Guy, and one was so severely damaged that it couldn't be repaired.
If these two were also destroyed, he wouldn't have suitable puppets to use in the short term.
Seeing Ebizo being repelled, Akira felt that the puppets' performance had been tested enough.
Ebizo's frontal combat ability was roughly above that of an elite jonin, but slightly weaker than a typical Kage-level ninja.
Basically, he was similar to Kakashi before Shippuden.
Being able to force him back meant that the puppet clone's performance was indeed close to that of a Kage-level ninja.
Although today's goal had been achieved, Akira found that there was still some chakra left in the Yin Seal.
So, he wanted to try one last ninjutsu from another scroll that Sasori hadn't had time to use during his battle with him.
Akira stretched out his hands towards Ebizo, opening the palms of his hands, and two gun barrels popped out.
"Ninjutsu: Corrosive Torrent."
Under the enormous pressure of the internal mechanism, two streams of water shot out from the muzzles of his palms at extremely high speed.
Ebizo quickly had the puppets block in front of him.
Two puppets, one squatting and one standing, opened four hands simultaneously like umbrellas, stacking four chakra shields together to form a larger defensive area.
This was exactly the Machine Light Shield Seal that Akira had just used.
The water jets hit the chakra shields, bouncing back and splashing a large amount of water, but they couldn't break the chakra shields.
Seeing this, Akira adjusted the mechanism at his elbow, and suddenly the original high-pressure water line turned into a flood, sweeping towards Ebizo.
The Machine Light Shield Seal had amazing defensive power, but after all, it wasn't a perfect defense.
The highly corrosive liquid passed through the gaps in the four chakra shields and splashed onto the two puppets.
The places that were splashed immediately emitted a harsh corrosive sound, thick smoke rising as they suffered severe damage.
Seeing that the two puppets were about to collapse and Ebizo was about to be exposed to the puppet clone's ninjutsu, a figure suddenly emerged from the ground behind the clone and stabbed it with a knife.
Akira didn't expect this move and was caught off guard. The blade entered from the waist and pierced out the abdomen.
Some red liquid flowed from the wound, and the water jet in his hand also stopped.
Puppet Sasori turned his head to look and found that the attacker was one of Chiyo's Ten Puppets of Chikamatsu.
One of the Ten Puppets fighting Akira's ten puppets not far away turned into sand and disintegrated.
Chiyo had taken advantage of his distraction to replace a puppet with her sand clone, allowing this puppet to hide underground and wait for an ambush.
Because the chakra reaction on the puppet was very weak, Akira didn't notice it in such a chaotic battle and was successfully ambushed.
At this time, Chiyo said:
"It's over, Sasori. I didn't stab your vitals, but you're too badly injured to continue fighting. Come back to the village and accept the punishment."
Chiyo could have stabbed Sasori's heart or cut off his head from behind, but she softened at the last moment when she was about to succeed.
Akira's puppet lost control and fell to the ground, the iron sand weapons disintegrating.
Puppet Sasori slowly turned around to face Chiyo, still expressionless, and said in a voice that didn't betray emotion:
"I didn't expect to be schemed against by you, Granny Chiyo. Since that's the case, I'll consider this your win.
But it won't be that easy to keep me here."
The puppet clone's drooping tail suddenly popped up, slicing off the puppet's weapon-equipped hand in one motion.
Then, it wrapped around the weapon embedded in its body and pulled it out.
The wound didn't bleed much, which made Chiyo frown.
Sasori's expression wasn't affected by the serious injury at all. Even with strong willpower, he shouldn't be so stoic.
Could it be that he couldn't feel pain?
An incredible thought emerged in Chiyo's heart:
"You mean..."
She was interrupted.
The iron sand and puppets that had seemed out of control were once again mobilized by Sasori, launching a sudden attack.
Caught off guard, Chiyo and the Sand ninja suffered a minor loss.
But to Chiyo's relief, Sasori didn't press the attack.
Instead, he commanded the iron sand and puppets to return to his side.
The iron sand gathered beneath Puppet Sasori, lifting him into the air.
Then, it formed enormous wings and carried him away at high speed.
He had to leave. The Yin Seal's chakra was nearly depleted.
Once it was gone, the puppet clone would only have the chakra the Rebirth Core could generate—barely Genin-level. At that point, escape would be impossible.
If he were caught, Akira would need to orchestrate a rescue. He had no choice but to retreat now.
The puppet clone, acting as Sasori, appeared mysteriously and left just as suddenly.
The Sand ninja were left stunned, and Ebizo, devastated, looked at his two severely damaged puppets with despair.
They had no means to pursue a puppet that could fly.
Only Chiyo stared into the sky where Sasori had vanished, her expression conflicted.
"Sasori... did you finally take that step?"
