After consuming the Magma-Magma Fruit, for reasons unknown, its power had altered Yoru's DNA, transforming his magma ability into a special kekkei genkai.
Stepping into the small courtyard outside his house, Yoru activated his magma power.
Glug… glug…
Half of his right arm turned into searing magma.
"Whew… that's the limit."
After pushing his ability to its maximum once again, Yoru realized that using his magma kekkei genkai to its limit would drain both his stamina and Chakra simultaneously.
"The amount of Chakra ultimately depends on the strength of the body… like the Uzumaki clan, whose massive Chakra comes from inheriting the Sage of Six Paths' physique."
This meant that as his body grew stronger—
His magma would only become stronger than Akainu's… and more enduring!
Because Chakra was extracted in advance and stored within the body, using his magma kekkei genkai consumed both stamina and Chakra—
Which meant the energy output behind his ability was even greater!
After devouring a large amount of food, Yoru used the method from the Body Limit Training Method to rapidly absorb nutrients and replenish his body.
When he fully recovered, although the change wasn't dramatic, he could clearly feel that both his Chakra reserves and physical strength had increased slightly.
"This is practically a bug!" Yoru said excitedly.
"This means I can train for longer than anyone in the Naruto world—and the results will naturally surpass theirs!"
From the original story, it was evident that aside from Naruto, who had the Sage's body and an enormous appetite, most ninjas ate relatively normal amounts.
And as powerful ninjas aged, their appetite would actually decrease.
This resulted in a very short peak period for most shinobi.
It also meant—
They lacked a method to break through their physical limits.
Talent determined everything.
At birth, your Chakra reserves and physical strength were already decided—and so was your future potential.
But Yoru—
With this training method—
Could continuously break through his own limits!
On one side, he was developing the latent potential within his body.
On the other, he was pushing beyond those limits, unlocking even greater potential!
Given enough time—
Reaching, or even surpassing, the Sage's physique might not be impossible!
The human body held infinite possibilities.
Shaking off his wandering thoughts, Yoru began training according to the force application and techniques described in the Body Limit Training Method, launching attacks at a wooden post.
(And don't question why there's a wooden post—this is a ninja household. Having one for taijutsu training is completely normal!)
To become strong—
First train the skin.
Then the tendons.
Finally, the flesh!
And to forge stronger skin and flesh—
You had to first destroy what already existed!
Bang! Bang!
Yoru's gaze was firm as he struck the wooden post relentlessly—fists, elbows, legs, knees, even his head—every part of his body smashing into it.
The special techniques ensured that every strike used his full strength, rapidly exhausting his stamina.
Every inch of his skin, tendons, and muscles was pushed into a state of extreme activity—becoming "hungry," ready to absorb nutrients and grow stronger.
"Ha… ha…"
After an unknown number of strikes, Yoru collapsed onto the ground, utterly exhausted, greedily gulping down air.
His body was covered in bruises—blue and purple patches everywhere. Some areas were even torn open.
Yet something strange happened—
The damaged flesh squirmed and healed rapidly. The bruises faded at an unnatural speed.
"So my recovery ability is still there…"
Panting heavily, Yoru stared at his body.
Even back on Earth, his physique had been abnormal.
If an ordinary person suffered a wound, it would take three to five days to heal.
For Yoru—
It only took minutes.
The most terrifying incident had been a fractured kneecap—
Which had completely healed within an hour.
Such a monstrous constitution had forced him to live cautiously, always afraid others would discover his abnormality.
But in the Naruto world—
With this terrifying body, combined with the Body Limit Training Method and the calamity-level magma kekkei genkai—
What kind of monster would he become?
After recovering a bit, Yoru once again consumed a massive amount of food, rapidly absorbing the nutrients.
Every cell in his body devoured the energy greedily—
Growing stronger.
This time, after exhausting all his strength through training, Yoru noticed something different.
The food that reached his stomach was digested and absorbed almost instantly!
The speed was so fast it left him stunned.
It felt like before the food in his mouth was even swallowed—
Everything in his stomach had already been digested.
After consuming five times the amount he had eaten before, his digestion finally returned to normal.
"That's… about three times a normal adult's intake…"
Yoru calculated silently, shocked.
"…Where am I supposed to get that kind of money?"
Although his parents had left behind some savings, and Konoha provided a subsidy, it was enough for now.
But this wasn't a short-term issue.
As he grew older—
His appetite would only increase!
Looking at his nearly empty refrigerator, Yoru felt a wave of helplessness.
Guess I'll have to work hard just to avoid starving to death…
After adjusting his mindset, he realized that his physical strength had improved significantly this time—he could clearly feel the increase in power.
Excited, Yoru sat cross-legged and began using the Chakra Extraction Method.
From each cell in his body, he drew out faint strands of Chakra, gathering them together and guiding them into his dantian.
"It really increased…"
Feeling the noticeable growth in his Chakra, Yoru was overjoyed.
After sensing it for a while, fatigue washed over him.
Unable to resist, Yoru collapsed into sleep.
