Naruto: The Architect

[09 minutes 24 seconds remain until skill shadow cloak deactivates.]

Shadow cloak is a skill based on dark and space affinity, when he use this his practicaly invisible unless of course you have eyes of sage.

'more than enough' Hiroshi thought, 

In the quiet of night, Hiroshi moved through the Hyūga compound using his shadow cloak skill, slipping through corridors and passing guard posts with. Even the Byakugan, which could normally detect chakra and hidden threats, couldn't see him as while he use his skill,

He approached the clan library's forbidden section, a place reserved only for select members of the main branch. 

His plan is simple: he will disguise as cloud shinobi and broke into library and shrines of the clans, he will copy all the technique and jutsu into his system core even if he got caught he always frame cloud shinobi.

The information inside the library's forbidden section was kept secret, containing advanced jutsu, sealing techniques, and clan secrets known only to those chosen by the elders. Taking a steadying breath, Hiroshi slipped inside, carefully shutting the door behind him.

"Nova, we're in. Let's start copying everything we can find."

"Understood," Nova replied smoothly, her tone carrying a hint of excitement as she began scanning the scrolls Hiroshi touched. 

Hiroshi moved between shelves stacked with dusty scrolls, with Nova's help, he copied complex sealing techniques, barrier jutsu, and secret Hyūga clan techniques, storing each piece of knowledge for later study. 

Every symbol, every formula, every line of chakra theory was logged into his system core.

After copying everything he needed, Hiroshi carefully slipped out of the library undetected, making his way back to his room as though he'd never left. 

Over the next few nights, Hiroshi repeated the process, extending his stealthy explorations to other clans. First, he visited the Nara clan library, where he collected information on shadow manipulation techniques and chakra restraint jutsu.

 Then, he went to the Yamanaka compound, gathering mind-control techniques and mental defenses. From the Akimichi clan, he learned about expansion techniques and the unique ways they manipulated chakra for strength.

Each night, his knowledge grew, and Nova's understanding of sealing techniques rose steadily. With every scroll he copied, Nova's progress bar crept closer to the 100% comprehension. For now, he was still under 60%, but he knew he was getting closer with every mission. 

Finally, after days of study and preparation, Hiroshi stood on a tall tree overlooking the Uchiha compound. 

The Uchiha grounds were well-guarded, but that wasn't his only concern.

His stealth skill would mask him from most detection, but the Uchiha's shrine was well guarded, even countless seals and other traps made by Madra Uchiha himself.

He took a deep breath, steadying himself as he watched the flickering lights of the compound below. His final targets included the Uchiha clan's heritage and the secrets of the Uzumaki shrine—and, if he dared, the Hokage's office itself.

"Ready, Nova?" 

"Always …This will be our most challenging infiltration yet."

Hiroshi reached the shrine and start finding weak points in barrier, It took him around an hour to bypass the intricate barrier around the Uchiha Shrine, a layer of seals and chakra threads more complex than anything he had encountered before. 

Nova analyzing each part of the barrier and helping him deactivate specific portions without triggering any alarms. 

As the final thread dissolved, he slipped through the invisible wall, activating his stealth skill just in time as he sensed another presence approaching. 

Shisui Uchiha!, his muscles tense as he saw the figure of the young Uchiha prodigy pass nearby. 

Shisui's gaze swept the area, his movements silent and controlled.

Hiroshi held his breath, not daring to make a sound until Shisui finally disappeared from view. 

Sigh~

Letting out a quiet sigh, he slipped into the shrine.

Inside, Hiroshi found rows of ancient scrolls and tablets etched with Uchiha clan secrets and knowledge long guarded by their bloodline. 

He carefully examined each one, copying every piece of information to Nova's database. The knowledge of Sharingan evolution, techniques exclusive to the Uchiha, and the foundations of the clan's powerful fire-based jutsu were now his to study.

But as he reached the far end of the shrine, something unusual caught his attention—a pair of vials, carefully preserved in protective seals. As he leaned closer, Hiroshi could make out two names etched into the base of each vial: 'Madara Uchiha' and 

'Hashirama Senju.'

Hiroshi's eyes widened. 'Their blood.' He could barely believe it.

 The preserved blood of two of the most legendary shinobi to ever live was right before him. 

With Nova's help, he quickly copied everything he could, committing the details of the preservation seals to memory, though he didn't need to tamper with the vials. 

For now, simply having the knowledge was enough.

With his work complete, Hiroshi moved to leave, making his way toward the exit as quietly as possible.

The night was quiet, Hiroshi, clad in a simple transformation disguise that mimicked the features of an older shinobi with nondescript blond hair and blue eyes, stepped silently out of the Uchiha shrine. 

Nova's voice chimed in his mind, her tone amused. "You're getting bold–," 

"Leaving so soon?" He heard voice from behind.

Hiroshi froze. The voice was calm yet sharp. 

Shisui Uchiha stood before him, his Sharingan spinning lazily, their crimson glow cutting through the dark.

"Care to explain yourself?" Shisui asked.

Hiroshi's mind raced. Shisui was no ordinary shinobi; Escaping was no longer an option. 

"He's scanning you," Nova warned. "You need to buy time or he'll see through the disguise. At other hand you will gain lots of experience fighting shinobi of his level."

Hiroshi tilted his head, his expression calm despite the storm of thoughts swirling in his mind. "Explain myself? Shouldn't you be thanking me for keeping the shrine's secrets safe, by order of Hokage we are searching the village for the spy."

Shisui raised an eyebrow. "Funny. I don't remember anything like that."

With a flick of his wrist, Shisui drew a kunai, his stance shifting into a defensive posture. A smile appeared on Hiroshi's face,

"Fine," Hiroshi said, his voice taking on a mocking tone. "Let's do this your way."

Shisui began with a swift Fireball Jutsu, Hiroshi jumped to side dogging it.

'Counter with lightning, like you did it instinctively.' Nova said.

Hiroshi formed a quick series of hand seals, releasing a bolt of crackling lightning that tore through the fireball, scattering embers into the night. Shisui's eyes narrowed as he adjusted his stance, clearly impressed by the speed of the counterattack.

"You're not bad," Shisui admitted, his Sharingan spinning faster. "But you'll need more than flashy tricks to beat me."

Hiroshi grinned. "Good thing I have more than flashy tricks."

The battle intensified as both fighters began to escalate their techniques. Shisui used his Sharingan to predict Hiroshi's movements, his strikes swift and precise. Hiroshi countered with calculated lightning-style jutsu, each strike guided by Nova's real-time analysis of Shisui's patterns.

At one point, Shisui used his famed Body Flicker Technique, disappearing in a blur and reappearing behind Hiroshi. But Hiroshi, anticipating the move, activated a gravity-based jutsu that created a crushing force field around him, forcing Shisui to retreat with smile?

Shisui stepped back, his expression turning serious. "You're skilled. I'll give you that. But I think it's time we end this."

Hiroshi's heart sank as he noticed the change in Shisui's demeanor. The air around the Uchiha seemed to darken, and a chilling pressure filled the space.

"He's activating his Mangekyō Sharingan," Nova said, her tone urgent. "You need to leave. Now."

Hiroshi cursed under his breath. "Guess it's time for an exit strategy."

As Shisui's eyes transformed, Hiroshi quickly formed a single hand seal. A ripple of energy surrounded him as he fired one of the power full lightning base jutsu on ground before activating shadow cloak.

Shisui lunged forward, his Mangekyō Sharingan locking onto Hiroshi—but the blond shinobi disappeared in an instant, leaving behind only a faint distortion in the air!

Shisui stopped mid-step, his Sharingan spinning wildly as he scanned the area. The intruder was gone, leaving no trace of chakra or movement.

The man standing before him was unusual, to say the least—tall and muscular, with wild blond hair and intense blue eyes. 

His face looked like it had been carved from stone, jaw set and gaze focused, but what really caught Shisui's attention was the foreign look of him. This wasn't a shinobi from Konoha.

And then there was the lightning. It crackled faintly around the man, weaving in and out of his chakra like an electric pulse. Shisui narrowed his eyes. 

'Hidden Cloud,' he thought. 'They specialize in lightning techniques, I can bet a whole month's pay that's where that guy is from.'

He turned his gaze back toward the Uchiha shrine, thinking what to do. The intruder had accessed their sacred grounds, possibly stealing critical information. Worse, they had managed to escape from him—a feat few could claim because of his eyes.

"I need to report this to Lord Hokage,"
