Iruka awkwardly turned to Kai and said, “Kai, don’t mind Naruto.
He’s just… bad at remembering people.” Even Iruka himself felt that the excuse sounded ridiculous.
No matter how poor someone’s memory was, there was no way they should forget a classmate they had spent six years with.
To Iruka’s surprise, Kai did not get angry.
He simply smiled.
“It’s alright.
I’m just not very good at socializing.” “Don’t say that,” Iruka replied seriously.
“This is just Naruto being hopeless with names.” For the first time, Naruto actually paid attention to Kai.
“Iruka-sensei, did Kai pass the graduation exam?” Iruka turned toward him with a forced smile.
“Of course he did.
You’re the only one in the class who failed.
What exactly have you been doing all these years?” Naruto scratched the back of his head awkwardly.
“Iruka-sensei, I’m just bad at the Clone Technique.
My Sexy Jutsu is really good though!” The moment Naruto mentioned the Sexy Jutsu, Iruka’s face flushed red with embarrassment.
“Don’t bring up that perverted technique!” Naruto shrank back slightly and muttered, “But you got a nosebleed from it…” “Quiet!
Don’t say that out loud!” Having his reaction exposed only made Iruka even more embarrassed.
Kai paid no attention to their antics.
Instead, he turned to Teuchi with a smile.
“One tonkotsu ramen, please, old man.” As he prepared the noodles, Teuchi grinned and said, “So you passed the Academy exam, huh?
That means you’re officially becoming a ninja now.” “I’ll throw in two extra eggs today.” Teuchi had always gotten along well with Kai.
“Thanks, old man.” At that moment, Ayame placed a bowl of sliced beef in front of him and said cheerfully, “I’m happy for you too, Kai-kun.” Kai was good-looking, polite, and a regular customer at Ichiraku Ramen, so Ayame had always liked him.
By the time Iruka and Naruto finished talking, Kai was almost done eating.
Because those two were here, he had eaten much faster than usual.
After finishing his meal, he stood up.
“Iruka-sensei, Naruto, enjoy your meal.
I’ll be going now.” Iruka blinked in surprise.
He had not expected Kai to finish so quickly.
Then he glanced at Naruto and immediately understood.
Still, he did not blame Kai.
After all, Kai’s parents had died during the Nine-Tails’ attack.
It was perfectly normal for him to dislike Naruto.
Naruto, however, remained completely oblivious and cheerfully waved goodbye.
“See you later, Kai!
Let’s hang out sometime!” Kai merely smiled faintly without responding before turning to leave.
Polite, yet distant.
Naruto could not tell, but Iruka could.
“He’s already much better than most people.
At least he doesn’t openly look at Naruto with hatred.” What Iruka did not know was that Kai kept his distance from Naruto simply because he did not want trouble.
After returning home, Kai lay down on his bed and closed his eyes, wondering when the system’s reward would arrive.
And whether the AFK System was even real.
He waited until late into the night.
Just as he was about to fall asleep, the system’s voice suddenly sounded in his mind.
“You have AFKed for one day.
Reward granted: Chakra Limit Removed.” Kai frowned, unsure what the reward actually meant.
Then, suddenly, a faint blue glow emerged from his body.
Having learned chakra extraction long ago, Kai instantly recognized the blue light as chakra.
But what shocked him was its density.
The chakra was so concentrated that it had become visible.
“What incredibly dense chakra…” “There’s at least a hundred times more chakra here than I originally had.” “So this is my reward?” In the next instant, the chakra surged wildly into his body.
At that moment, Kai felt an indescribable sense of comfort spread throughout his entire body.
It was so overwhelming that he nearly cried out loud.
If he had not bitten down on his blanket to suppress himself, the neighbors might have misunderstood what he was doing in the middle of the night.
After a long while, he finally absorbed all of the chakra completely.
“This is unbelievable… I can actually absorb chakra from the outside world.” Normally, a ninja’s chakra was created by extracting energy from their own cells.
That was how Kai had always done it as well.
In the past, he had worried that extracting chakra might weaken the body.
But clearly, he had overthought things.
This world operated differently from the one he once knew.
The laws of nature here were unlike those of his previous life.
In this world, extracting chakra did not harm the body unless it was overused excessively.
However, the amount of chakra one could produce was heavily limited by physical constitution.
Simply put, members of ninja clans generally possessed far superior physiques compared to ordinary ninja, which naturally granted them larger chakra reserves.
Kai’s chakra reserves had always been very ordinary.
That was because his parents had both been civilian ninja.
Previously, his chakra reserves could not even compare to Sasuke’s.
The gap between them had been roughly tenfold.
Compared to Naruto, however, the difference was even more absurd—tens of thousands of times greater.
And that was without even counting the Nine-Tails’ chakra.
That calculation only accounted for Naruto’s Uzumaki bloodline.
As Naruto grew older, his chakra reserves would continue increasing, meaning the gap between them would only widen.
In this world, bloodline talent was incredibly important.
Without it, at best, one could only shine briefly like Might Guy.
But now, Kai could feel that his chakra reserves had become a hundred times greater than before.
His current chakra levels were roughly comparable to those of a jōnin.
More importantly, he could absorb chakra directly from the outside world.
That meant he could replenish chakra anytime, anywhere.
Very few ninja could accomplish something like that.
The natural energy present in the environment vastly exceeded the chakra within Kai’s own body.
Right now, he could feel external energy constantly flowing into him in an endless stream.
And its quality was extraordinarily high.
What Kai did not realize was that the chakra he absorbed from the outside world was actually natural energy.
Naturally, its quality far surpassed ordinary chakra.
Natural energy could not only be used in combat; it could also nourish and strengthen the body.
Kai’s body had never been particularly outstanding.
In fact, it was his physical limitations that prevented him from absorbing even more chakra.
If he possessed Naruto’s natural constitution, his current chakra reserves would likely exceed Naruto’s by more than a hundredfold.
At the moment, Kai simply felt indescribably comfortable.
Even soaking in a hot spring could not compare.
“This system is incredible.
It already gave me such a huge surprise on the very first day.” “Unfortunately, aside from the Three Basic Techniques, I don’t know any ninjutsu at all.” His parents had not left behind any ninjutsu scrolls either.
After all, they had only been ordinary chūnin, not elite ninja.
“Slowly but surely.
Maybe the AFK System will provide some in the future.” “Just increasing my chakra reserves by a hundred times is already amazing.” “My chakra reserves are far beyond Sasuke’s now.” Sasuke’s chakra reserves were already far greater than those of ordinary Academy students.
They simply seemed small when compared to Naruto’s.
But compared to Naruto, almost everyone’s chakra reserves looked insignificant.
The Uchiha Clan was also famous for possessing powerful chakra.
They simply fell slightly behind the Uzumaki Clan and Senju Clan.
After all, without massive chakra reserves, it was difficult to properly wield the Sharingan— Let alone the Mangekyō Sharingan.
