No matter what complex jutsu it was, his Heaven-Defying Comprehension allowed him to successfully learn it just by analyzing the theory or watching it once.
But he hadn't fully grasped just how impressively broken the 'One-Click Max Level' Gold entry truly was in this specific context.
As long as it was an ability, technique, or even a fragmented chakra source he had assimilated, he could upgrade it to its absolute maximum potential in an instant.
"In that case... doesn't this mean I've basically gained the full power of the Three-Tails for absolutely nothing?" Shiro asked aloud.
[Ding! Yes, Host. Would you like to initiate the upgrade protocol?]
"Do it," Shiro commanded without a second thought.
He mentally activated the *One-Click Max Level* on the Three-Tails Fragmented Chakra.
*RUMBLE!*
In an instant, an absolutely massive, oceanic surge of dense, aquatic-blue chakra flooded into Shiro's body. The sheer scale and pressure of this energy were simply immense, expanding his already vast reserves exponentially.
It could be said that previously, if describing Shiro's chakra capacity as 'greater than a Tailed Beast' was considered a slight hyperbole or metaphor, then right now, that sentence was a literal, undeniable statement of fact. He possessed the full, unfiltered power source of a Bijuu without the annoying drawback of having a giant, grumpy turtle sealed inside his gut trying to take over his mind.
Things became much more peaceful after that.
Following the successful hostile takeover in the Land of Waves, Shiro essentially had no urgent tasks to deal with until the Chunin Exams officially began.
So, Shiro spent his days entirely on a self-improvement loop: mastering the stolen Forbidden Jutsu, performing his daily sign-ins, and synthesizing low-level entries in the system.
However, his cosmic luck seemed to have hit a dry spell. For several days in a row, he didn't pull any particularly useful entries from the daily gacha. It was highly probable that his baseline strength and progression were currently so astronomically high that anything below a Purple or Gold entry simply didn't provide a noticeable boost to his combat capabilities anymore.
"The Chunin Exams should be starting in a few days. I really hope I can draw something interesting soon," Shiro muttered, analyzing his status panel.
He was not satisfied with his current situation. He needed to become even stronger.
While the general populace of the Ninja World believed they were living in an era of unprecedented peace, Shiro knew the terrifying reality. There were massive, apocalyptic undercurrents swirling just beneath the surface.
The Akatsuki Organization, puppeteered by Obito and Nagato, was quietly gathering its strength. The snake Sannin, Orochimaru, was currently plotting a full-scale invasion of Konoha. And lurking even further in the shadows were heavyweight, god-tier threats like Madara Uchiha and the Otsutsuki Clan.
Only by continuing to break his limits could Shiro comfortably play the game against those monsters when the time came.
"System, initiate today's sign-in!"
[Ding! Congratulations to the Host for obtaining the Gold Entry: 'Chakra Body Refining Technique'!]
[Description: Chakra Body Refining Technique - A supreme physical enhancement passive. The Host can compress excess chakra directly into their cellular structure. As long as the Host's chakra reserves are not completely exhausted, their physical body will not suffer structural damage from internal or external kinetic forces.]
"A Gold drop?!" Shiro's eyes widened in delight. The dry spell was finally over.
He immediately read the detailed description.
"As long as my chakra isn't exhausted, my physical body won't take damage..." Shiro took a deep, steadying breath.
This technique was practically tailor-made for him!
Between the boundless vitality generated by his max-level Wood Style and the literal ocean of chakra he just obtained from the Three-Tails upgrade, Shiro's reserves were practically infinite. It could logically be stated that with this passive technique active, Shiro would simply never suffer physical injury in standard combat!
"Wait... this is incredibly interesting," Shiro suddenly smiled, a bold idea forming in his mind. "If I pair this *Chakra Body Refining Technique* with the *Eight Inner Gates*... wouldn't I be able to open the gates and unleash their power without suffering any of the physical backlash?!"
Thinking of the forbidden taijutsu he had archived from the Scroll of Seals, Shiro rapidly linked the two concepts together.
After using his comprehension to master the Eight Gates previously, Shiro hadn't bothered using them. The jutsu functioned by forcefully removing the body's natural limiters, causing catastrophic, often irreversible damage to the user's muscles, bones, and circulatory system—especially the later gates.
While his Wood Style granted him miraculous regenerative abilities, Shiro had so many other, less painful methods of causing mass destruction that tearing his own muscles apart seemed redundant.
But now? With a passive ability that prevented physical damage as long as he had chakra to burn? He felt he absolutely had to test this theory.
---
But for now, all that training made a man hungry.
Realizing he had essentially been a shut-in for a full week since returning from his mission, Shiro decided he should probably step outside and grab a proper meal.
However, upon stepping out of his apartment complex, Shiro noticed that the village streets were exceptionally crowded today. It wasn't until he spotted the unfamiliar forehead protectors worn by several passing groups—bearing the symbols of Sand, Rain, and Grass—that he fully understood the situation.
"Ah, I see. The foreign Genin have arrived. The Chunin Exams are about to begin," Shiro murmured.
He hadn't expected the timeline to advance so quickly, but thinking back to the original plot, Team 7 had indeed been entered into the exams almost immediately after their chaotic mission to the Land of Waves.
"Well, since I have nothing pressing to do, I'll go check out Ichiraku Ramen."
Ultimately, Shiro chose his favorite haunt. The foreign ninja likely wouldn't know where the truly elite food stalls were hidden away.
Sure enough, unlike the flashy restaurants on the main strip which were currently packed to the brim with loud Sand and Rain genin, there were only a few regular customers sitting inside the humble Ichiraku stand.
"Ah, Shiro! Welcome back! It's rare to see you out and about these days!" Teuchi waved excitedly from behind the counter.
"Hey, Teuchi-san. I'll have the usual extra-large pork tonkotsu," Shiro greeted, taking a seat. "By the way, where's Ayame?"
"Oh, she ran to the market to buy extra groceries. There are a lot more mouths to feed in Konoha today, so she might be a while!" Teuchi explained warmly, turning to prep the noodles.
Shiro nodded, sitting quietly and waiting for his meal.
"Hmph. I originally thought Konoha was supposed to be impressive, full of legendary figures like the Sannin... but it turns out the new generation is just a bunch of pathetic worms!"
A harsh, arrogant voice drifted over from the seats next to him.
"I know, right? That guy who bumped into us earlier... Uchiha Sasuke? He seemed to have nothing but a bad attitude and trivial tricks. Completely vulnerable!" a girl's voice chimed in, sounding thoroughly unimpressed.
Initially, Shiro wasn't very interested. If foreign Genin wanted to sit around and brag to boost their own egos before an exam, let them brag. Being arrogant wasn't a crime.
But when Shiro glanced over and registered the distinctive appearances of the trio sitting a few stools down, he immediately realized who he was dealing with.
A boy entirely wrapped in a black bodysuit with purple face paint, a blonde girl carrying a massive iron fan on her back, and a short redhead with dark rings around his eyes and a massive gourd slung over his shoulder.
*So, it's the Sand Siblings,* Shiro noted internally. Gaara, Kankuro, and Temari were casually discussing their earlier run-in with Team 7.
"It doesn't matter," Gaara stated, his voice devoid of any emotion, staring blankly ahead. "From what I have observed, besides perhaps the Uchiha, there is no one else in this entire village who is even worth killing."
Gaara's tone implied he didn't take anyone in Konoha seriously in the slightest.
"It seems the Kazekage was right to send us," Kankuro chuckled darkly. "If we crush Konoha's 'finest' in front of all the other hidden villages during the tournament... Sunagakure's reputation will skyrocket!"
"Kankuro is absolutely right," Temari agreed strongly, leaning on the counter. "The legacy of the previous Hokage has carried this village's reputation for too long. If we ruthlessly trample their new generation in the arena, Konoha will lose its position as the premier military power."
"Hey! You've got a lot of nerve, you know that?!"
Perhaps unable to stomach listening to a bunch of arrogant foreign brats loudly disrespecting their village in a local establishment, one of the older, civilian regular customers sitting nearby slammed his cup down and spoke up indignantly.
"You outsiders win a minor scuffle against a few fresh academy brats and suddenly you start acting like Kage-level experts! Try talking all that trash after you've faced our strongest!" the local shouted angrily.
Little did the brave civilian know, those specific words were the absolute worst thing he could have possibly said around Gaara. It immediately sparked the sociopathic redhead's murderous, competitive desire.
"Oh?"
Gaara slowly turned his head. His cold, soulless, sea-foam green eyes locked onto the civilian. "Tell me... who exactly is the 'strongest' fighter in Konoha?"
The sheer, suffocating killing intent radiating from the small boy made the surrounding customers, including the brave local, feel a sudden, terrifying chill run down their spines. They hadn't expected a child to possess the aura of a mass murderer.
"H-Hmph! Speaking of Konoha's Number One Genius... it obviously has to be Lord Shiro! D-Did you think it was going to be me?!" the civilian stammered, terrified but stubbornly defending his village's pride by invoking Shiro's name.
Unexpectedly, upon hearing that such a heralded individual actually existed, Gaara was immediately filled with a dark, twisted interest. He desperately wanted to find and crush this 'Number One Genius' to prove his own existence.
"Interesting," Gaara whispered. "But you still annoyed me."
Even though he had his answer, Gaara's unstable mind decided the civilian still needed to be punished for speaking out of turn. He subtly raised two fingers.
Sand silently spilled from the gourd on his back, rapidly condensing into a dense, spear-like tendril aimed directly at the civilian's chest.
*CRACK!*
Just as the hardened sand spiked forward, it was effortlessly intercepted and violently shattered into loose dust by a single, casual backhand slap.
Gaara: "?"
Kankuro: "?!"
Temari: "?!"
"How is that possible?!" Gaara's blank expression finally cracked, replaced by genuine shock. His sand was infused with chakra; its defensive and offensive density was incredibly high. How could it be shattered into dust by a simple, physical slap?
"Is your supposedly ultimate defense really this fragile?" Shiro sighed, casually dusting the sand off his knuckles. He hadn't even used chakra; his base physical strength, enhanced by the Senju vitality and his new passive, was absurd.
"Y-You are... Lord Shiro!" The terrified civilian immediately recognized the handsome boy who had just saved his life.
"Pay for your meal and hurry home. The streets are going to be a bit chaotic with the tourists around," Shiro advised calmly, not taking his eyes off the Sand trio.
"So... you are this famous 'Number One Genius' they were talking about! Shiro, was it?" Temari demanded, standing up and reaching for her fan. As the eldest sibling, she felt compelled to assert dominance.
"Temari, don't bother talking to this guy. I'm just going to..." Kankuro sneered, reaching for the bandaged puppet on his back.
But before Kankuro could finish his threat or draw his weapon, Gaara suddenly reached out and forcefully yanked his older brother back by the collar.
"Gaara?! What are you doing?!" Kankuro choked, stumbling backward.
"This person..." Gaara whispered, his voice trembling slightly, his eyes wide as he stared at Shiro. "How is this possible...?"
Gaara found it completely impossible to comprehend. He, a Jinchuriki who lived for murder, was actually feeling an immense, suffocating sense of primal dread radiating from the boy sitting across from him.
It wasn't just him, either. Deep within his subconscious, the One-Tails Shukaku—the monster of the sand—was actively trembling in fear
