Naruto: I Am Crazy with the Simulation System!

『Ding~ The host is thinking in the right direction. The closer your bloodline gets to the Ōtsutsuki, the more attribute points you'll gain from growth.』

『However, be aware—the Ōtsutsuki clan is of the long-lived species. The closer you get to them, the slower your growth becomes...』

Reading the system prompt, Kirin nodded. He had already made up his mind—to refine his bloodline further and continue walking the path of becoming closer and closer to the Ōtsutsuki.

But before that, it was time to take inventory of the loot he'd gained from this simulation.

"Let's head back to Granny Yukina's place first."

Although the White Zetsu in the area had already been wiped out, old habits died hard. If he didn't shut himself away when working, Kirin would always feel a faint sense of unease.

He deactivated his clearly unnatural Six-Tomoe Sharingan, jogged back while pretending to be out of breath, and shut himself inside the small cabin.

First was the Tsuchikage's inheritance scroll. It contained the fusion method for Dust Release, along with several derivative jutsu.

In addition, there was Dustless Bewildering Cover, a technique that could rival Transparent Release but had far greater endurance, and a clone technique called Fission Technique that could split off cells to create a duplicate virtually identical to the original body.

He also obtained several of the Second Tsuchikage's research manuscripts, which included extensive notes on training with Nature Affinities and conducting experiments to fuse Kekkei Genkai. They would definitely help Kirin avoid many detours in the future.

Then came the Mangekyō Sharingan. This time's simulation had given him more Mangekyō Sharingan than he could have hoped for:

Uchiha Itachi's left and right eyes—Amaterasu and Tsukuyomi. Obito's dual Kamui. And the inheritance left behind by Uchiha Setsuna: the fusion of a sealing technique and time manipulation—Butōgyokumei.

Five Mangekyō Sharingan in total.

Uchiha Kirin counted all the Sharingan he'd obtained across simulations.

"Wait... this isn't right!"

Counting the Mangekyō Sharingan he already had, the number from Itachi and Shisui added up just fine...

But there were three Kamui Sharingan—and only one eye from Uchiha Setsuna.

"One extra... and one missing. The total number is unchanged, but there's clearly a problem with the Mangekyō Sharingan!"

Kirin didn't want to ask the system directly about something that might be a bug. Instead, he decided to deduce things based on previous information.

First, in the last simulation, he brought in three Sharingan:

He gave Kotoamatsukami to Granny Yukina during the fight against Obito.

The eye containing Butōgyokumei hadn't fully awakened at the time, and he had transplanted it into Uchiha Setsuna, the original owner.

The last one—a Kamui eye stolen from Kakashi—was meant to be used by Kirin himself to fight Obito, but he never got the chance.

After Setsuna and Granny Yukina passed away, he reclaimed those two eyes.

The newly obtained dual Kamui were snatched straight from Black Zetsu.

Now it made sense.

Sharingan given as rewards from the system and brought into simulations couldn't increase out of thin air. But once upgraded, their progress would carry back into reality!

However, eyes taken directly inside the simulation could be reclaimed repeatedly.

For example, if in one simulation, Uchiha Kirin stole Obito's dual Kamui and got a pair of Mangekyō, he could do the same in another simulation—essentially collecting infinite sets of Kamui eyes!

"Looks like fusing Eternal Mangekyō in the future won't be a problem at all!"

Uchiha Kirin picked up a Kamui Sharingan and tried pressing it into his eye socket—only to end up screaming in pain with no effect.

The mysterious ocular technique within the Six-Tomoe Sharingan that could absorb bloodlines showed no reaction to the Mangekyō Sharingan.

"So that's the real challenge—how to transplant the eyes and still retain the original ocular powers afterward!"

In his memory, when Sasuke transplanted Itachi's Mangekyō, Tsukuyomi disappeared.

As for Amaterasu, Sasuke already had that ability, so it was unclear whether the powers fused together—or if, like Tsukuyomi, the original ocular techniques vanished during transplantation.

"Looks like I'll have to pay Orochimaru a visit in the next simulation... or maybe track down Amado. Worst case, I could use Edo Tensei to revive the dead..."

As for awakening his own Mangekyō Sharingan—

Uchiha Kirin wasn't worried at all.

Ever since he'd obtained the Six-Tomoe Sharingan—a fusion of Uchiha and Uzumaki bloodlines—he'd gained a sharp intuition, a sixth sense unlike any other.

In other words, Kirin already knew exactly what kind of "scene" he would need to show himself in order to perfectly awaken his own Mangekyō Sharingan.

"Uchiha Itachi... it's time for you to receive the ultimate surprise I've prepared for you."

...

As for the target he would set using the Loot System—

After a brief moment of thought, Uchiha Kirin decided to go with Itachi. Sasuke was still too young. Whether it was the Indra chakra inside him or the Mangekyō Sharingan, neither had fully developed. Getting high returns would require investing time to cultivate him.

So why not go straight for Itachi?

He'd been eyeing the Three Sacred Treasures for a while now—time to grab two of them and have some fun!

Once he awakened his own Mangekyō, he'd deal with Sasuke—and the Indra will behind him—in one fell swoop.

〖Simulation Start〗

〖Loot System Target Set—Uchiha Itachi〗

〖8:00 AM〗

After organizing all the Mangekyō Sharingan, jutsu scrolls, and manuscripts, you summon Boss Black Cat.

You present the token, give a brief self-introduction, then stroke the flustered and honored feline a few times. You order him to disguise himself as a stray and sprint straight out of the village, heading toward the Land of Lightning.

Once you establish a mental link with him, you'll activate the Reverse Summoning Technique.

You strap the Black-Blade Tachi to your waist and glance at Granny Yukina, who's kneading dough.

You think for a moment, but ultimately decide not to leave a note.

Taking down Black Zetsu isn't something that just anyone can do. Only someone truly invincible stands a chance against that scheming mastermind who's manipulated the Shinobi World for a thousand years.

And you—at this moment—are preparing to become that invincible person.

〖9:00 AM〗

You use the Transformation Technique to disguise yourself as an adult and put on a black cloak.

Timing it perfectly, you start trailing Uchiha Itachi from a distance—he's escorting Sasuke to school.

Transparent Release grants you unparalleled stealth, and with the Six-Tomoe Sharingan, you don't even feel the chakra consumption—it recovers faster than you can spend it.

Uchiha Itachi, though possessing exceptional intuition, has no way of detecting your presence. In fact, the constant failure to find any anomalies causes him to question himself.

But that hypersensitive intuition keeps warning him of danger—making him feel perpetually on edge.

Like a cat toying with a mouse.

Bit by bit, you're playing with someone who's arrogant to the extreme, overconfident in his abilities, and imposes his will upon others.

You're tearing apart his pride, his ambitions—everything he holds dear.

Bit by bit. Inch by inch.

Turning it all into nothing...
