Naruto: Back in Ancient Times

Title: War Across Dimensions 3

...

Haki… As most would describe it, is an Energy that originates from the spiritual plane. Energy which is then converted to various forms. As the Law of Energy states, Energy can't be created nor destroyed, but converted from one form to another.

This is the reason why on a dimensional scale, beings residing in said dimension can't all have the same level of energy, whether physical, spiritual or otherwise.

Certain beings - Humans - most especially, tend to evolve with every obstacle they face. They thrive and emerge anew, different from who they were prior to facing said obstacles.

This enables them to develop certain levels of Haki, mainly the Observation or Sensory Haki.

When a Human interacts with Power on a certain scale on a continuous basis, they tend to develop an understanding of said Power Levels. However, when said Power Level is then shown or revealed to actually be a false reality, their minds undergo one of two processes.

Either it shuts down or it creates a new reality.

The mind is one of Creation's greatest Marvel's, limited by what it is fed. The truly strong ones would either resist staunchly or directly ignore whatever changes it perceives, while the weak ones would shut itself down in a bid to protect itself.

One such scenario occurred the very moment Kaguya burst out of her Cocoon.

One had to understand that unlike in the original timeline, Not all Living beings were made to fall into the Illusion of the Mugen Tsukuyomi. As for those currently unconscious around the world, only children, the old, physically and mentally weakened individuals and Shinobi enjoyed that luxury.

As for those awake to witness the scene, either visually or merely perceiving it, close to seventy percent of them were forced into an unconscious state, and that was only from her passive Divine Haki being released.

"You two…" Kaguya began, her voice devoid of emotions as she locked her gaze on Naruto and Sasuke. "I would've thought you possessed Hagoromo and Hamura's Chakra…but alas…Indra and Ashura, Huh?"

The veins around her eyes twitched slightly before returning to their states. That mere twitch gave her all the information she needed from the chakra the two possessed. "Then it was Hagoromo who gave you that Jutsu." She said,

Sasuke and Naruto, the World's current strongest, couldn't even move under the pressure of her Haki. 'This Chakra…it's far greater than Madara's. I can't believe such a person existed…' Sasuke thought in trepidation, cold sweat already pouring down his face.

"You!" Kakashi called out to Kaguya who didn't bother to turn to him, but she already had him under her sights, and as if knowing this, Kakashi continued. "What are your intentions?"

Kaguya for a moment didn't really know what to make of that question. What were her intentions? Truly, she didn't know. She just felt a tug on her consciousness and followed. She already had a fulfilling life and a future far greater than most living beings could fathom…What truly, were her intentions for this little planet?

But then again…

"This Place…is my precious possession. Let's stop Fighting." She said with an inward sigh. These humans didn't really possess the appeal she was expecting. Due to not actively observing Human development in relation to chakra, she only heard what she knew of the Shinobi world from Hinami and Ria who had both descended.

But compared to the Galaxy destroying Techniques she was used to fighting with and against, the little she had observed had made her lose interest.

This was her honest opinion, however…

"Huh!?

"Then.."

She wasn't really above the childish impulses that assailed her at that instant.

To think that her useless son would ask these two brats to welcome her after the long period of time she had spent away.

"...Here that is."

Instantly, Naruto and Sasuke found themselves in a World of Lava. Thankfully, she had teleported them to the skies of the Dimension.

'Let's see how these brats Shun had spent so long to turn out.' Kaguya thought as she observed the two…'What?!' She exclaimed internally as she observed a few inclusions to her Teleportation.

With a slight frown, she teleported those few away, leaving Naruto and Sasuke. 'Weird, is my Teleportation Failing due to this body?' She thought as she checked her connection with the body.

"Hmm." She hummed to herself as she found the reason. Madara, who should have been merged completely with the husk to form this body, had a remnant of him lingering on. 'Shun's intervention…I presume.' she surmised and frowned slightly causing the Lava to boil over.

"Screech!"

A loud shriek pulled her out of her thoughts as she looked over to see an Eagle being pulled into the Lava below with the Rinnegan bearing 'Shinobi' falling together with it.

The Lava that shot up from the quake in her dimension has spilt on it, causing its early death. 'Not my fault though. Who asked him to Summon an Eagle in here? Can't he just fly or something like his brother over there.' Kaguya thought before watching the two who had managed to survive the fall.

Sasuke…as she came to understand, was standing on a platform created from Naruto…the other kid's Orb.

"Naruto…I'll be frank with you. The world will come to an end if either of us dies…"

'Hmm? How would the world come to an end?' Kaguya thought as she heard him. She however, didn't move to attack as they continued their conversation.

…

Meanwhile, The world outside was undergoing a drastic change. The environment was visibly dying out. People collapsed due to the drain of Life force. Mountains crumbled due a lack of energy. However, the few strong ones who were observant enough noticed a few things.

"Madara's rods are disintegrating…I can finally move…Now if I can just get to the spot where I felt Madara's Chakra. I might understand something." Hashirama said as he slowly stood up.

"What's more is there to learn, brother?"

"Tobirama." Hashirama acknowledged the other man's presence.

"I'm more disturbed by Kuchiki's- Shun's offer." Tobirama said as he watched his brother try to regain control over his body.

"What's there to be disturbed about? Under normal circumstances, I would've jumped at the offer." Hashirama said with a wry smile.

"But?"

"But our time is gone? My time is gone. I'm tired, plus Mito would be bored if I don't come back soon." Hashirama said before letting out a hearty laugh.

"This is something more than that, Elder brother. This concerns this World's future."

"I know. Have you forgotten that I played a part in this current world? The present now..was my future. Our future. We worked hard for it. That's why I can willingly fight for it, even in death."

"So-"

"But that! That is their future. The kids of the next generation should grow up hearing about heroes of their time, not us." Hashirama finished righteously.

"..."

Tobirama kept silent as he followed his brother. He understood his brother's point of view, but Kuchiki did say that they didn't need to interact with the Humans. They'd be a whole separate body focused on protecting the planet as a whole.

"I'll accept."

"Tobirama!" Hashirama stopped abruptly at Tobirama's words.

"Brother. This isn't about our time. Think about it. Beings on Madara's level or higher. That's exactly what Kuchiki said. How do you expect these kids to be able to fight against them?" Tobirama shouted back.

"Think about it! We don't need a divided country to place our alliance with. We're doing something more than just protecting a village. We're protecting the World. Our collective home! Look at that!" Tobirama said as he pointed to the sky where five moon-like objects floated.

"According to Kuchiki, that's a dimension related to just one person. Now imagine a group of them. And then imagine them attacking our descendants!? Tsunade! Your granddaughter!"

"That's what I'm trying to protect. I have not an iota of doubt that Kuchiki would have measures placed against us having any contact whatsoever with the humans so!...I'm accepting."

Similar conversations were being held between those who were doubtful about it. Some however, were totally unbothered. As far as they could continue fighting, what better joy was there?!

…

Kaguya continued observing the kids and couldn't help but reminisce a little about her two boys. Naruto and Sasuke in front of him looked very similar to them…their aura was so similar.

"I think that's enough planning from you. Here I come," Kaguya said and flew towards them at speeds she felt was fast enough, however, a look of surprise flashed through the duo's eyes…one which Kaguya didn't miss.

And Naruto, although surprised, quickly raised his hands and threw a punch which Kaguya quickly countered with a Vacuum Palm.

Naruto's Chakra fist clashed with her Vacuum Palm generating massive waves that shook the Lava below, and while Kaguya was calmly receiving Naruto's fist, Naruto was…

"RAAARGH!!"

…shouting as he tried to push the woman, even if a little. However, reality and expectations differed as Naruto was pushed back by the counter-force of their clash.

Yet, it seemed as though everything was all according to plan as Naruto grinned while being blown away.

'What a weird kid?' Kaguya thought as she opened a portal and slid inside, however, as she did, she felt a purple light flash where she floated moments ago.

'What? You think with my Byakugan, I can't see the massive floating body above me? You really look down on me, huh?'

'{|Wha- You can speak with me?! You have access to the Fourth Wall?|}'

'Hump!' She snorted but didn't reply.

Author: Damn!

…

Stepping out of the portal, Kaguya was met by the two boys she had thought to teach a lesson. 'Perhaps I should fight seriously?' she thought. "That was impressive teamwork… I guess?" She said, trying to sound similar to Shun when he was sparring with his subordinates or students.

As she was speaking however, another portal opened up In Front of her and right behind the duo, and before the duo could react, they were rendered immobile.

"Such complacency in front of your enemy." Kaguya said as she stretched out hands to feel their faces. "You'd be dead if I wanted…" she added.

She noticed that both of them wanted to say something but apparently, her hold was too strong on them.

"You have the Rinnegan. Use it well." She said as she looked at their hands and showed a slight smirk. 'That brat really wants to seal me away…again.'

As she was thinking this, Black Zetsu had managed to appear and began telling the two his thousand year scheme, and as though to coincide with what he'd been saying, Kaguya said. "I detest you two…Hagoromo…Hamura…You're mine."

To think that after so many years…those two still clung until that ideology of theirs.

"My role has come to an end. You shall return with me to the Almighty God that is mother."

'Wait…What's this guy talking about?' Kaguya's train of thought suddenly paused as she heard that last bit, looking over and analyzing Zetsu, she couldn't help but frown at his figure. 'Perhaps its role should come to an end.' She thought and immediately swallowed up the bit of her chakra in Zetsu.

"You two…aren't the Entirety of Shinobi History!!" Naruto screamed while managing to free himself from Kaguya's hold much to her amazement. She didn't allow it to show on her face though.

Naruto, who had broken free grabbed at the shadow extending from her hands and pulled, tearing away the shadow also keeping Sasuke bound

"We need to create an opening so that sealing jutsu can be launched." Sasuke said after they had managed to create a distance from Kaguya.

"I know! And the only thing that'll do now is That Jutsu."

"That Jutsu..?"

"Yeah…"

'I wonder what they're planning now.' Kaguya thought as she observed the two. 'This is getting boring and I've not even started trying…Oh? They're coming-Hmm? Black flames?' Kaguya thought as she looked at the Black thing wriggling on her body. 'Is this perhaps…That Amaterasu?' she wondered.

Unlike what she'd expected. The Amaterasu didn't really cause her the pain she had expected it to cause her.

'Hmm.' she hummed while quenching the flames with a wave of her hand while wondering what Naruto would do with that many clones surrounding her.

"[Ninpo: Reverse Harem no Jutsu!]" He said as the clones puffed and transformed into what would be an assortment of varying Perfect Male Species.

However, compared to Her man, they were subpar.

This was her last thought before tilting her head to the side, effectively dodging the punch being thrown by Naruto.

"Exquisite use of your intelligence, young man. Unfortunately, you picked the wrong female." Kaguya said and a Portal opened below Naruto, and with a slight touch, Naruto was sent flying into the dimension.

"Now…how about that private lesson on 'How To Use Your Rinnegan'"

A/N: So...this will be my last... update for this week. I know it may not seem like anything new, but it actually is. After today, I'm not sure I'll have the time to come online for some time.

I'll be writing my Mechanical Engineering final year last examination paper on the Monday, effectively bringing my five years of studying to a close.

The entire week will be spent going over my final project which I will be defending on the Friday of that same week.

I know I can bring out time if I wished to, but this is kinda important, I'm not really into it, but I gotta just do it and do it well since I've been studying due to my parents paying my tuition for five good years. I gotta show the results...don't I?

After all, everything worth doing, worth doing well... until it becomes useless 😅😅

Anyways, enjoy.
