Chapter 13, the Flying Thunder God Technique.

At that moment, the Third Hokage arrived with the Anbu, accompanied by Danzo and members of the Root organization.

The Anbu, unaware of the true story, were horrified by the scene before them.

"This is beyond gruesome!"

"Uchiha Itachi and Uchiha Chiba went too far!"

"Check for any survivors!"

The Third Hokage and Danzo exchanged glances and issued orders. They had to maintain the act they were putting on.

Kakashi, standing nearby, found it hard to believe.

"Uchiha Chiba actually awakened the Mangekyō Sharingan and caused such a tragedy? It's completely different from the Chiba I knew, both in terms of strength and actions."

The Third Hokage, aware that Kakashi was focused on Chiba, spoke in a deep voice.

"Don't let yourself be distracted. They might still be around. Let's handle the current situation first."

"Yes, Lord Hokage," Kakashi replied, taking a deep breath and suppressing his doubts.

As the corpses were being carried out one by one, the Anbu remained speechless. Despite having taken part in numerous ruthless missions, nothing compared to the scene they were witnessing.

"Lord Hokage, we found a survivor!"

"Quickly, send someone to the Ninja Hospital!"

The Third Hokage felt a sense of relief upon seeing Sasuke alive. Now he could explain things to Itachi.

Danzo took this opportunity to leave and instructed the members of the Root organization to collect the Three-Tomoe Sharingan.

"Lord Danzo, some of the corpses are missing their Sharingan."

"Damn it! Continue the search and don't let any of them escape," Danzo ordered coldly, his face darkening.

Unbeknownst to them, Itachi was secretly observing everything. They were also unaware that Chiba had already infiltrated their hideout.

...

The Konoha Secret Art Library.

It housed all of Konoha's ninjutsu, including forbidden techniques and the original seal scrolls.

The Protectors, Konoha's most elite Anbu unit, stood guard. However, Chiba activated his Mangekyō Sharingan and swiftly eliminated them.

He then encountered a barrier and a sealing technique.

"I didn't expect to use this ocular technique so soon," Chiba remarked with a smile, feeling a glimmer of hope in his heart.

Pupil Art: Destiny!

Simulate: Kamui!

Whoosh!

Chiba's body suddenly became ethereal.

It worked!

Overjoyed, Chiba walked towards the barrier as if entering another dimension, effortlessly passing through it.

Inside the secret vault, Chiba gazed in astonishment at the enormous chamber, larger than a football field.

Rows of bookshelves filled with various ninjutsu scrolls and reference materials lined the room.

Countless secret techniques and forbidden jutsu were stored within.

However, Chiba did not share Orochimaru's ambition to learn every ninjutsu.

His goal was singular: the Flying Thunder God Technique.

Swiftly, Chiba located a bookshelf labeled "Space-Time Ninjutsu" and hurried toward it, feeling a sense of surprise.

In addition to the Flying Thunder God Technique, Chiba discovered several summoning contract scrolls in the vault.

First, he opened the Flying Thunder God Technique scroll and used his Sharingan to copy it.

After considering his options, Chiba chose two intriguing summoning scrolls to take with him, regardless of their potential use.

Finally, he stumbled upon the original sealed book.

"As expected, it's sealed. If I force it open, it will self-destruct," Chiba muttered, feeling a tinge of disappointment. After some hesitation, he decided not to destroy the sealed book, keeping it for a future opportunity.

He took the Water Style ninjutsu scroll from the Second Hokage as a well-deserved reward.

With his goal accomplished, Chiba left the secret vault. However, instead of leaving Konoha, he hurried to another location.

...

The base of the Root organization.

"Who?!" someone exclaimed as Chiba suddenly appeared, activating his Mangekyō Sharingan to control the Watcher.

To his surprise, there were quite a few individuals present. However, they offered no resistance in the face of Chiba.

Utilizing his Sharingan, Chiba gathered information and arrived at a secret vault protected by numerous enchantments and seals.

"Another barrier," Chiba sighed, realizing that he would need to learn some sealing and enchantment techniques in the future.

He employed Kamui once again.

With no risk of blindness, Chiba used his ocular technique without any concerns.

An image of an Uzumaki appeared in his right eye, rendering him ethereal.

All barriers and spells proved futile, allowing Chiba to effortlessly enter the secret vault.

Then, he was taken aback by what Danzo had amassed.

Secret techniques from prominent clans, Forbidden Techniques, even Sharingan eyes—including the unexpected white ones!

And there it was, his target—the First Hokage's cells!

"It seems I'm quite welcome here," Chiba smirked, opening his Sharingan to record useful secret techniques he discovered.

Destroying this place would be futile, as Danzo likely had many backups.

Chiba retrieved an antique camera and snapped photos of all the mysteries—the Sharingan, the First Hokage's cells—capturing them all.

He collected all the Sharingan eyes and sealed away the First Hokage's cells using a Sealing Scroll.

After completing these tasks, Chiba turned and departed.

"Danzo, I hope you enjoy this gift," Chiba muttered from a distance, gazing at the Uchiha clan's territory.

Just moments ago, he had sent corresponding photos of various secret techniques to the major clans, even sending a few cheeky shots to the Hyuga clan.

He was certain that Konoha would be in an uproar the next day.

Taking one final glance at Konoha, Chiba rushed to the designated meeting place with Obito.

The weasel hadn't arrived yet.

"You didn't cause any trouble, did you?" Obito asked impatiently as he saw Chiba's arrival.

Chiba spoke nonchalantly, his words carrying an air of indifference.

A twitch formed at the corner of Obito's mouth, indicating that something would unfold after their departure.

Stepping aside, Chiba activated the system silently, taking stock of his gains from this endeavor.

As he glanced at his attribute panel, he couldn't help but inhale deeply.

Chakra amount: LV6, equivalent to Six Paths level.

Pupil Power: LV6, possessing the mighty Rinnegan.

Both Fire Style Chakra Form Change and Nature Transformation had reached LV3.

However, these two attributes started at the Jonin level, which meant they had now ascended to the super Kage level.

In terms of ninjutsu, the number seemed countless—techniques like Extinguishing Arrogance and Extinguishing Arrogance.

There were even a few LV4 Fire Style ninjutsu at his disposal.

"I'm likely stronger than Madara in his Eternal Mangekyou Sharingan state right now!" Chiba exclaimed, his emotions swirling as he stared at his panel.

However, he couldn't help but feel a tinge of regret knowing that such a situation was unlikely to occur frequently. While there might be attributes with higher values in the future, achieving such comprehensive growth would be rare.

Before long, Itachi arrived.

Though he made an effort to conceal it, Itachi's mood was clearly unsettled.

Obito refrained from saying much and promptly led the two away from Konoha.

"Let's go. It's time for us to meet with the other members of the Akatsuki organization."
