Hokage Sign-in System

"It's Uchiha Itachi of the Anbu."

"Itachi is the family's mole within the Anbu, how could it be him?"

"Yesterday, when the Patrol Squad was ambushed, I saw his Sharingan. The pattern of the Mangekyo, I'll never mistake it in this lifetime."

Uchiha Rei spoke slowly, his voice not loud, yet it stirred up a storm. Uchiha Itachi activating his Mangekyo was a family secret, known only to a select few.

In an instant, the assembly hall fell silent, then erupted like gunpowder.

"How could it be him?"

"Uchiha Itachi, wasn't he always loyal to the village?"

"Why? Why would he attack the clan?"

Amidst the clamor, Uchiha Rei's gaze grew calmer. He no longer wished to act. The three clan members who died yesterday, their blood had not yet dried, and he himself had almost met his end in the Yellow Springs. He had already made plans to escape the Night of the Uchiha Clan Downfall and flee Konohagakure, this land of strife, but in the end, he was poisoned and forced to stay.

Since I can't leave, I won't. Uchiha Itachi, Uchiha Obito. I will show you all a good show.

"Where is Itachi now?" a clan elder asked in a deep voice.

Uchiha Fugaku retorted, "That's not a question you should be asking."

"What is his stance exactly?" another voice chimed in, "Is it the clan? Is it Konoha? We have the right to know the truth."

"Itachi... is indeed carrying out a special mission."

"He's a double agent," Uchiha Fugaku explained, "To gain the trust of Konoha's high-level, he bore the darkest mission, but his hands are also stained with the blood of his kin."

"A double agent? To gain the trust of Konoha's high-level, he could kill his own people? Who will be next? You? Or me?"

"Then who is he loyal to? The Hokage, the Clan Head, or..."

"He has already personally dealt with our people," someone roared, "Perhaps we should abandon Itachi!"

"Maybe this brat is lying to us," an elder clan member turned his gaze to Uchiha Rei, his tone filled with coldness and suspicion.

Uchiha Rei just smiled, his smile devoid of any warmth. I originally planned to lie, and you would have believed me then. But I speak the truth, and you begin to doubt me. People only hear what they want to believe.

"I can confront Uchiha Itachi face-to-face," he said coldly, "As long as he dares to show up."

The assembly hall fell silent again, a stillness like dead water. No one spoke.

Now, the most crucial thing was no longer debate, but finding Uchiha Itachi.

But where was he?

Outside Konohagure, the night was deep. A long-haired figure wearing a tiger-striped mask and a black robe appeared silently, wandering through the forest like a ghost.

"How ridiculous," he sneered, his voice sinister. "They couldn't even handle the patrol team."

Opposite him, a silhouette in an Anbu uniform was crouched silently on a utility pole, watching the ground like a crow. Uchiha Itachi, his expression cold, his Mangekyo Sharingan quietly bloomed.

"Didn't you act later?" Itachi asked coldly. "You had the chance to stop him, but you let him go."

"His Fire Release is strong, and I didn't want to alert him," Obito asked, "Why are you dealing with him now?"

"Because he's trying to escape Konoha."

"I think he's already aware of our plan," Itachi's tone carried a hint of caution. "Better to kill by mistake than let him go. It's a shame we didn't kill him. He's still alive."

"He didn't see our true faces," Obito said dismissively. "He doesn't know who we are. He won't find out anything."

His figure began to blur, the spatial power of Kamui swirling around him, drawing him into the void. "Under the light of the Mangekyo, all crises will vanish."

Uchiha Itachi stood silently on the utility pole, his figure blending into the night.

"It's... Mangekyo."

Standing at the end of Konohagure's alleys, a flash of red light passed through Uchiha Rei's left eye, but he quickly concealed it, leaving no trace.

Since leaving the Uchiha clan's Assembly Hall, his heart had been churning with excitement, but his outward appearance remained as calm as still water.

This was the Mangekyo Sharingan, the embodiment of the Uchiha bloodline's power, his trump card now.

Without the Mangekyo, he wouldn't have the confidence to kill Uchiha Itachi.

With the Mangekyo, he finally had the right to refuse.

The world of Naruto was, after all, a game of eyes.

Naruto, also known as Black Zetsu finds mom, or Legend of the Eyes of the Five Great Village Melee. Eyes were the strongest mechanism in the world of Naruto.

He quickly walked into an uninhabited forest. Confirming that all was silent, he took a deep breath and closed his eyes.

"System," he thought silently.

Instantly, a cold and familiar electronic prompt sounded in his ears:

[Sign-in System activated.]

[Welcome to the world of Naruto.]

[The host can sign in at any location possessing a trace of destiny.]

[You can perform one effective sign-in per day. Some special locations can be signed in at repeatedly.]

[The deeper the serendipity, the richer the rewards.]

As the prompt sounded, a virtual panel appeared before him.

He quickly scanned the text, his heart gradually understanding.

Konohagakure, his home, had no aura of serendipity and could not be signed in at.

But just now, that Uchiha Clan Assembly Hall was the "place of serendipity" the system had mentioned.

He had already successfully signed in there once, and from it, obtained the Mangekyo Sharingan!

Konohagakure, the core of the Hokage world, held countless opportunities for him to sign in.

However, at this moment, he had no spare capacity to indulge in future fantasies.

"I've been poisoned."

If he didn't detoxify quickly, even the awakened Mangekyo would likely become useless.

"The system can only sign in once a day."

"To survive, I must find a key location before the next sign-in."

His mind raced, searching for opportunities in Konohagakure related to "detoxification."

There were three ways to detoxify.

First, a healer who mastered superb Medical Ninjutsu, like Tsunade.

Second, someone with a special Physique, such as the Sage Body of the Senju Clan.

Third, a powerful Dojutsu that could directly ignore or control toxins.

"That place..."

A flash of inspiration, and he recalled a Forbidden Zone forgotten for many years.

Without hesitation, he set off and soon reached his destination.

Beneath the forest, an abandoned Underground Medical Base, left behind by Orochimaru before his defection.

It was said that Orochimaru had conducted many Human Experiments here. As a famous Surgeon of Konoha, perhaps Orochimaru had left many opportunities here.

Unfortunately, all the Wealth left by Orochimaru had already been recovered by Konoha or Root. The entire Laboratory was empty. There was nothing.

Fortunately, there was nothing, and Rei easily entered the Laboratory. Next, he would have to wait until dawn to sign in.

"At least no one is disturbing my sign-in..." He sat down, leaning against the corner, circulating his Chakra to suppress the poison, and waited for dawn.

Time was almost up to 12 o'clock. Just as he was about to summon the system to sign in, he suddenly heard a faint Footstep Sound.

His eyes snapped open, his Pupils contracting.

Someone was here.

He wasn't the only one who had entered this abandoned Orochimaru Laboratory.
