..."Did you hear? The practical combat test is starting soon."
"Yeah, I heard this test is going to be difficult."
"What's there to fear? No matter how hard it is, how bad can it get? Practical tests are just a stage for those geniuses."
"That's true, but I heard that the results of this practical test will affect our team assignments after graduation."
"Right, right, right, I heard that too. And Hokage-sama will even be coming then."
"Really? That's awesome! Who do you guys think will stand out in this practical test?"
"My guess is Sasuke. He's excellent in every subject."
"I think so too, and Sasuke is just so handsome."
...The sounds of conversation reached Naruto's ears, leaving him in a daze for a moment.
Immediately after, he was filled with sudden ecstasy!
He was back!
And... Naruto sized up his surroundings.
A spacious tiered classroom with blackboards hanging on both the front and back walls.
On both sides of the back blackboard, two large characters for 'Ninja' were posted.
In front of the front blackboard stood a young man.
The young man wore a standard green Ninja flak jacket and a Ninja headband on his forehead.
Naruto's eyes instantly lit up when he saw this familiar person.
It was Iruka-sensei!
He had successfully returned to the timeline when he was eight years old!
Orochimaru had succeeded!
Naruto looked around once more.
The infatuated Sakura, his posturing best friend Sasuke, Shikamaru who was interested in nothing... everyone was here.
Naruto's eyes instantly welled up with tears.
He knew this wasn't a dream; it was real.
He actually had the chance to start all over again.
Thirty years later, the Ōtsutsuki Clan invaded the Ninja World once again.
The Ninja World had fallen into chaos once more.
Kawaki, whom he had adopted, backstabbed him and used Eida's power to rewrite the memories of the entire world.
Boruto was no longer his son, but a public enemy of Konoha.
Sasuke had also been absorbed by the God Tree.
He had been on the brink of death.
Fortunately, while he was sealed, he was rescued by Orochimaru.
That guy used Uchiha Shin's ability to save him and Hinata.
Naruto still remembered in the cave, Orochimaru once asked him: if he had a chance to do it over, what would he do?
He thought for a long time before saying, "If I had a chance to do it over, I would choose to unify the Ninja World and gain the power to protect everything!"
"The divided Ninja World always allows the Ōtsutsuki to find opportunities to destroy it."
Orochimaru understood Naruto's intent and brought out the modified treasure, Karasuki.
And he told Naruto...
This was his newly modified treasure, Karasuki, which could project a target's soul into the past.
But it could only project one person, and if the projection succeeded, Karasuki would vanish.
Naruto fell silent.
This meant that if he were to return to the past, two people would have to stay and guard this place.
Orochimaru and Hinata saw Naruto's hesitation.
He stated that he had Truth to accompany him here and wouldn't be lonely.
Hinata also said she wanted to stay on this side to protect Himawari and Boruto.
Orochimaru said that if Naruto went back to the past and the plan succeeded, the future here would also change.
Thus, Naruto accepted the suggestion.
Furthermore, Orochimaru duplicated his own knowledge and memories, as well as those of Sasuke and Hinata, for Naruto to take back and find their past selves.
Because if he returned to the past without any help, it would still be very inconvenient for Naruto to take action.
Now it seemed that Orochimaru's plan had succeeded.
Naruto looked at the three sealing scrolls in his arms and couldn't help but grip them tightly, breathing a sigh of relief in his heart.
But now another problem arose.
Although he had been reborn, it was impossible to bring back his massive amount of Chakra.
And his current body was clearly not strong enough yet.
Furthermore...
Naruto's gaze was deep.
In his past life, even with such powerful strength, he couldn't completely crush the Ōtsutsuki Clan.
He even caused Kurama to vanish.
In the future, even if he mastered those powers, it might not be enough to have a chance at resisting.
This made Naruto clench his fists.
He wanted the power to protect everything, but now it seemed that this goal was somewhat illusory.
Once upon a time, he thought Nine-Tails Mode and Sage Mode were the powers to protect everything.
But with the invasion of the Ōtsutsuki Clan, that idea gradually shattered.
If these strengths were truly powerful enough to protect everything, then why did Kurama have to sacrifice himself?
Why did Kawaki still dare to backstab him?
Why was Sasuke still absorbed by the God Tree?!
Thinking of this, Naruto's resolve to become stronger grew even more intense.
"Ding! Host's wish detected. Assisting Hokage System activated!"
"Obtained one Newcomer Reward Pack!"
What?
Naruto's body jolted, and his eyes suddenly widened.
A system?
Was he hallucinating?
Or did something else come along with his time travel?
Soon, Naruto discovered that by being reborn, he seemed to have brought something incredible with him.
This system was like the Scientific Ninja Tools developed by Dr. Katasuke.
It could help Naruto enhance his strength.
But there were still other differences.
"System, how should I use you?"
Naruto asked in a cautious, low voice.
"This system can help the host grow into a Hokage and later develop the Ninja village as a Hokage, providing a full range of services."
"The host only needs to continuously collect prestige points and improve their own status to use prestige points to purchase abilities, bloodlines, and items."
"Specifically, the host can check through the status panel."
So that was it.
With the system's explanation...
Naruto knew that for now, he just needed to collect prestige and raise his status.
prestige points could be compared to money, used to buy items, abilities, and bloodlines from the system mall.
These things came from various major worlds.
This was also the first time Naruto learned that besides his own Ninja World, there were actually other worlds.
And status could unlock mall items.
The better the items he wanted to buy, the higher his status had to be.
Now, Naruto had a general understanding of how the entire system operated.
He opened the system panel to check.
[Name]: Uzumaki Naruto
[Age]: 8 years old
[Status]: Student
[Strength]: Apprentice Ninja (Chunin)
[Ninjutsu]: Harem Jutsu (Proficient), Transformation Jutsu (Mastered), Substitution Jutsu (Mastered), Clone Jutsu (Mastered), Rasengan (Proficient), Multiple Shadow Clone Jutsu (Proficient), Summoning Technique (Proficient), Thousand Years of Death (Proficient), Rasengan Variants (Proficient), Sage Mode (Proficient), Nine-Tails Mode (Proficient), etc.
[Chakra]: 0.5 Ka
[Chakra Nature]: Wind
[prestige points]: 0
Looking at the panel in front of him, Naruto's lips couldn't help but twitch.
He did know a lot of Ninjutsu.
But with his strength only being at the Apprentice Ninja level, it seemed there was still a long way to go to improve.
But what did the 'Chunin' in the parentheses afterwards mean?
Could his true strength be at the Chunin level?
According to the information provided by the system...
Ninja World strength was divided into six levels by the system: Apprentice Ninja, Genin, Chunin, Jonin, Elite Jonin, and Kage level.
Among them, Kage level was further divided into Low Kage, Mid Kage, High Kage, and Super Kage.
Those who surpassed Super Kage level were Six Paths.
In any case, Naruto had already gone through every level of strength in his past life.
But soon, he was attracted by his Chakra amount.
0.5 Ka?
What did that mean? Was it a lot or a little?
"System, what does a Chakra amount of 0.5 Ka mean?"
Naruto inquired.
"0.5 Ka means the host currently possesses half of Kakashi's Chakra amount!"
Naruto: ⊙(・◇・)?
Since when did Kakashi-sensei's Chakra become a standard of measurement?
If that was the case, his Chakra amount was actually quite decent.
But he soon pushed these thoughts to the back of his mind.
At the same time, his confidence was ignited.
With the system, he would surely be able to unify the Ninja World and protect it along with his loved ones!
Naruto planned to round up all those Rogue Ninjas from his past life and have them all join Konoha.
Since prestige was the nourishment for this system, he would earn prestige for it!
Naruto remembered that tomorrow seemed to be the practical test. If that was the case, he could completely harvest a wave of prestige tomorrow.
But... Naruto glanced at Sasuke beside him.
He had to hurry and restore this guy's memories and knowledge.
The Uchiha Clan could not be wiped out.
In Naruto's plan, there were many hidden powerhouses in this Ninja World, and he wanted to bring them all into Konoha.
He would build Konoha into a truly supreme village!
"What are you looking at, Dead Last?"
Just as Naruto was staring at Sasuke, thinking about his plan...
Sasuke, who was nearby, seemed to feel Naruto's gaze and retorted with a look of displeasure.
Dead Last?
Naruto was stunned for a moment.
Only then did he realize this guy was talking about him.
His face couldn't help but darken.
As expected, even with rebirth...
Sasuke's personality was still very unpleasant.
What a tsundere guy.
Author: The protagonist's strength is not only related to his abilities but also to his Chakra amount; it's a comprehensive assessment.
And 1 Ka of Chakra is actually quite a small amount.
