Shindai froze in place due to Obito's words, and an idea sparked in his mind.
Shindai looked bruised and swollen now, but with a Ninja's recovery ability, he would likely be back to normal in a little while.
So... could Kannazuki achieve self-recovery when injured?
No matter what material was used, no matter how hard, there would always be a limit to what it could withstand.
No matter how hard, could it withstand a Tailed Beast Ball?
Of course, this was just an example; a material that could withstand a Tailed Beast Ball probably didn't exist at all.
As a puppet, it was certainly impossible for Kannazuki to recover like a person.
Even if it could recover like a person, it would be useless, because recovering like a person takes time.
What Shindai thought of was a method that would allow Kannazuki to recover the instant it was injured.
When Shindai saw Obito step through a puddle, the water in the puddle rippled and then quickly returned to its original state.
Shindai suddenly felt that the countless threads in his mind had connected into one.
Obito saw Shindai still standing still and asked in confusion, "Huh, Shindai, why are you still standing there? Let's go."
Shindai exclaimed with joy, "Ahahaha, I understand! I understand! I know what to do!"
Shindai immediately ran towards his home.
Minato Namikaze, Uzumaki Kushina, and Obito looked at each other, completely unable to understand what had suddenly gotten into Shindai.
Kakashi looked at the sprinting Shindai and guessed, "Could it be... that Shindai was beaten silly by Lady Kushina?"
Uzumaki Kushina pursed her lips, "That shouldn't be the case; I actually hit him quite lightly, not hard at all."
Kakashi, Obito, and Rin Nohara stared at Uzumaki Kushina in disbelief.
Shindai was already bruised and swollen; and that was considered light?!
Minato Namikaze said worriedly, "Let's go check on him, in case something really happened."
...
Rushing back home, Shindai eagerly took out a lump of Sand Iron.
Shindai used his Magnet Release Ninjutsu to manipulate this lump of Sand Iron.
The Sand Iron continuously changed shape under Shindai's control.
At this moment, Minato Namikaze and the others also arrived at Shindai's house and saw Shindai manipulating the Sand Iron.
Just as Obito was about to speak, Shindai interrupted, "Don't disturb me! I must focus completely right now! I have so many ideas! If I don't seize this inspiration, I don't know when it will come again!"
Obito closed his mouth and stood silently, watching Shindai manipulate the Sand Iron.
They realized that Shindai might be creating something, so they dared not disturb Shindai, not even moving a muscle.
An hour quickly passed.
Kakashi and the others seemed to have been subjected to a Body Immobilization Ninjutsu, not moving an inch.
But their expressions began to grow increasingly strange.
Because for this entire hour, Shindai had continuously manipulated the Sand Iron, changing its form, it felt... like he was playing.
Another two hours passed.
Obito's feet were numb from standing, and he was starting to lose his balance; it was incredibly boring.
Because he was afraid of disturbing Shindai, he had to stand still.
Just as Obito was about to gently shift his feet and try to leave, Shindai suddenly stood up from his chair.
Shindai looked at the cubic Sand Iron in his hand with a look of pleasant surprise: "It finally worked! It really can be done this way!"
"Phew!"
Hearing that Shindai had finally succeeded, Obito, Kakashi, and Rin Nohara all breathed a sigh of relief.
In fact, not only Obito, but Kakashi and Rin Nohara were also getting restless.
Obito immediately leaned in to examine the cubic Sand Iron in Shindai's hand, asking in confusion, "It feels... nothing special. Isn't it just changing the shape of the Sand Iron? Couldn't you do something like this easily, Shindai? Was it necessary to spend three hours on it?"
Kakashi also stepped forward, looking at the cubic Sand Iron and guessing, "Shindai spent three hours on it, so it definitely isn't just about changing its shape. There must be something special about it, right?"
Shindai snapped his fingers, "Exactly! Kakashi, use your strength to smash this cubic Sand Iron apart."
Kakashi didn't say a word and directly punched the cubic Sand Iron, which instantly shattered.
However, the next second, the shattered Sand Iron reassembled, forming the shape of a cube.
Rin Nohara asked in confusion, "There's nothing special about it, either. After it was broken apart by Kakashi, didn't you just reassemble the shattered Sand Iron, Shindai?"
Uzumaki Kushina stroked her chin and said, "I think I've figured something out, but I don't know how to explain it. It seems like the cube itself is a bit strange."
"Mmm-hmm, Lady Kushina got it a little bit right. Did Lord Minato figure it out?"
Shindai was extremely proud now. If even Minato Namikaze couldn't figure it out, then it was too successful!
However, as a genius among geniuses, Minato Namikaze had already seen through it: "After this cubic Sand Iron was shattered by Kakashi, you didn't control the Sand Iron to reassemble into a cube, but it automatically reassembled into a cube, right?"
Although Minato Namikaze had figured it out, Shindai didn't feel disappointed; he was still incredibly excited.
Shindai nodded and explained, "That's right, I didn't manipulate the Sand Iron; it automatically reassembled into a cube.
Magnet Release can imbue non-magnetic objects with magnetism. So, I imbued this Sand Iron with magnetism, from strong to weak, layer by layer, eventually forming a cube.
When Kakashi destroyed this cube, the strongest magnetic Sand Iron converged first from the center, and then layer by layer, it continued to converge, finally reforming the cubic Sand Iron."
Obito smacked his lips, "It feels... not that great."
Shindai said discontentedly, "If you don't understand, then shut up! The stronger the magnetism, the harder this cube will be, even harder than Ninjutsu tools. However, no matter how hard the material, it will be destroyed if it exceeds its limit.
The disadvantage of puppets is that if a part is damaged, that part cannot be used, and if it's completely broken, it can no longer fight.
But if I use the principle of this cubic Sand Iron to create puppets, then..."
Kakashi immediately understood Shindai's meaning: "Then even if this puppet is completely destroyed, it can use magnetism to reconstruct itself, right?"
Shindai's grin nearly reached the back of his head: "Exactly! This means I will have a puppet that cannot be destroyed, and I can also use the properties of magnetism to do many things, such as changing its form during battle by rearranging the order of the Sand Iron, and even using the principle of positive and negative poles to suddenly launch the Sand Iron as a hidden weapon, and so on.
I'm confident that once I develop this puppet, it will be incredibly powerful!"
Minato Namikaze and the others were somewhat surprised; listening to Shindai's explanation, the puppet Shindai was about to create seemed to indeed have great potential.
