[With your current bite strength, eating copper was laborious but still possible.]
[Mainly because copper had some softness. As long as the pieces weren't too large, you could eat it relatively easily.]
[But as the volume and density increased, eating copper became more and more strenuous for you, but you liked this feeling of effort.]
[Because it was challenging.]
[Moreover, besides increasing your body's sturdiness, copper could also enhance your flexibility.]
[If a Shinobi lost their flexibility, their mobility would inevitably become less convenient.]
[Having a body with perfect flexibility and incredible sturdiness filled you with excitement just thinking about it.]
[It took a year, but you ate every type of copper that could be refined.]
[Some copper was relatively soft and easily eaten, while some was very hard and took you a long time.]
[But none of this effort was in vain.]
[By now, you could ignore the Five Basic Nature Transformations, and no Ninjutsu could leave a mark on you.]
[Except for Onoki's unreasonable Dust Release.]
[Although you hadn't tested it, you knew it wasn't a Ninjutsu that could be blocked with flesh, no matter how sturdy.]
'Indeed.'
'Onoki's Dust Release is just broken.
'If you encounter it, you can only dodge, or you're definitely dead.'
Takumi nodded in agreement.
The Dust Release that Onoki learned from Nidaime Tsuchikage was the foundation of him becoming Sandaime Tsuchikage.
It was also the reason he could still hold the Tsuchikage position at such an old age.
[After finishing copper, your next target was iron.]
[This was also a very big challenge for you.]
[Onoki, following your instructions, gave you various types of iron refined to different hardness levels.]
[You still tried them in order of hardness.]
[But even with the softest iron, you encountered trouble.]
[The hardness of iron exceeded expectations, but fortunately, you could handle eating small fragments.]
[At least compared to diamond, this iron was much more fragile.]
['After I finish eating all of this, I'll be the hardest man in the entire Shinobi World!' You secretly encouraged yourself, then resolutely ate the small iron fragment.]
[Fortunately, your body, after years of tempering, was also very sturdy. Otherwise, the small iron fragment could easily cut your throat, causing internal bleeding and death.]
[Through bit-by-bit attempts, starting from small iron fragments.]
[When your teeth could handle it, you started gnawing on iron blocks.]
[After several months of effort, iron blocks became like tofu in your mouth.]
[At this level, although other hardness levels of iron blocks still posed difficulties, the speed of conquering them increased significantly.]
[At least, it didn't require taking several months or even a year every single time.]
'Finally, the training is almost complete.'
Takumi couldn't help but sigh.
Over these past few years, while other children were playing, Little Takumi was gnawing on dirt.
While other children started refining Chakra, Little Takumi was gnawing on bark.
While other children were learning Shinobi knowledge at the Academy, Little Takumi was gnawing on ore.
At the age when others would graduate from the Academy in two or three years, Little Takumi could already gnaw on iron blocks.
By now, Little Takumi's body was incredibly sturdy.
Although his other talents were average, relying on his powerful physique, Little Takumi could even ignore all enemy attacks, charge right up to them, and knock them out with one punch.
It's very simple and unadorned.
With this incredibly sturdy body, not just his peers, but even the village's Jonin might not be his match.
After seven or eight years of hardship, now was truly the time to reap the rewards.
Once he could eat iron as easily as tofu, and finally even eat diamond, Little Takumi's body would undoubtedly be the strongest.
[It took a year, but you finally succeeded in eating every type of iron, all reaching the ease of eating tofu.]
[By now, your body was extremely powerful. In all of Iwagakure, only Onoki was your match.]
[For your age, this was enough to be called genius.]
[But you weren't satisfied yet. Your gaze fell upon the diamond.]
[However, even you, who could eat iron blocks like tofu, still couldn't easily eat the diamond.]
[Having no other choice, you had to ask Onoki to use Dust Release to cut the diamond into small fragments, which you then swallowed directly.]
[Even though you couldn't bite it, as long as your body could absorb it, you could become stronger.]
[Onoki had Medical0nin on standby, ready to perform surgery to remove the diamond fragments from your stomach if you showed any abnormal reaction.]
[But you digested the diamond fragments very smoothly, and you could clearly feel your body strengthening.]
[This feeling was also something you awaited for a very long time… only in the very beginning did you have such an obvious feeling.]
[This was enough to show just how hard diamond was.]
[You excitedly swallowed all the diamond fragments and asked for more.]
[Onoki excitedly agreed to your request. He always believed your talent was a previously unseen Kekkei Genkai.]
[Any investment in you now would strengthen your family.]
"Pity, it's a talent, not a Kekkei Genkai."
Takumi shook his head.
[With Onoki's help, you strengthened your body at a rapid pace.]
[By the time you were twelve, the typical graduation age, your body had reached the impervious to swords and spears level.]
[You could withstand any attack standing right where you were.]
[Of course, Onoki's Dust Release still had to be excluded.]
[That wasn't an attack an ordinary person could withstand.]
[Thus, your divine skill was complete, and you smoothly graduated from the Academy.]
[You began your Shinobi career.]
"The arduous training is over, finally time to make your mark?"
Takumi looked expectant.
He couldn't wait to see Little Takumi go around beating up various powerful figures.
Although Little Takumi's defense was complete, he still had a fatal weakness.
But as long as he didn't encounter that type of enemy, Little Takumi was invincible.
[Because of your outstanding strength, Onoki didn't place you in an ordinary graduate team but assigned you to a team with rich experience.]
[Their mission was to steal intelligence in the Land of Water, but their whereabouts were leaked, and they were ambushed.]
[The three of you faced twenty Kirigakure's Shinobi.]
[But you showed no fear.]
[Countless shuriken and senbon came flying at you.]
[But you stood firm, not moving, shielding your two teammates.]
[Amidst a series of dense clinking sounds of metal on metal, all the projectiles were blocked by your flesh.]
["This is impossible!" A Kirigakure Shinobi shouted in shock.]
'Nothing's impossible.'
'This is a hardened body forged through nearly ten years of arduous training.'
'If it couldn't even block these kunai, wouldn't those ten years have been wasted?'
Takumi looked on with a disdainful expression.
He knew very well that even twenty Kirigakure's Shinobi joining forces wouldn't be a match for Little Takumi.
[After the shock, the Kirigakure's Shinobis used Ninjutsu one after another. For a moment, various Water Release Ninjutsu formed torrential currents with fierce force.]
[But you stood like an extremely sturdy city wall, allowing the Ninjutsu to blast against you without wavering in the slightest.]
[The Kirigakure's Shinobis were completely shocked.]
["It must be a Genjutsu! Kai!" A Kirigakure's Shinobi, unable to believe it, thought he had discovered the truth, but when he performed the release seal, nothing around him changed.]
["It's not a Genjutsu!" Another Kirigakure's Shinobi's eyes showed despair.]
Taijutsu was ineffective.
Ninjutsu was also ineffective.
Naturally, they had no way to deal with such an opponent.
'So pitiful.'
Takumi shook his head repeatedly, but his eyes were full of excitement.
Because the stronger Little Takumi performed, the higher the final rating would be.
This meant he could also possess such a sturdy body.
How could he not be excited?
