Konoha Year 46.
Within the Land of Fire, on the main road leading to Konohagakure.
On a ox cart,
A handsome black-haired young man, covering his head, struggled to sit up.
"Hiss... my head hurts so much, where is this?"
Shin opened his eyes, and what greeted him was a white-haired child in front, holding the ox cart's reins.
As if sensing his companion behind him had woken up, the white-haired child turned his head.
He said to Shin expressionlessly:
"You're finally awake. I thought you might not make it to the Village."
"You... you... are Kakashi?" Shin pointed at the white-haired child.
Seeing the somewhat familiar mask, he widened his eyes, wanting to say something.
However, a wave of headache struck, causing him to lie down again.
"Hey, hey! Why did you lie down again?" Seeing this, Kakashi quickly pulled the ox cart to a stop.
With a leap, he arrived beside Shin.
At this moment, a voice echoed in Shin's mind.
[Ding~ Detecting that the host has awakened Past Life Memories, the Entry Extraction System has finished charging. Welcome to use it!]
"Hmm?"
"System and Past Life Memories? Did I transmigrate?"
Suddenly, a surge of information flooded Shin's mind.
A moment later, having processed this information, he understood everything.
He, Uchiha Shin, after a life of hard labor in his previous life, following a mudslide.
Was transmigrated by a cheat called the 'Entry Extraction System'.
Reincarnated into the Naruto World, and was born into a good family, becoming an Uchiha.
He is twelve years old this year, an orphan.
However, before awakening his Past Life Memories, his talent was also like his previous life's hard labor.
It could be said to be extremely mediocre.
As a Ninja clan, the Uchiha usually train their Ninja within the clan.
There are only two situations where they would be sent to the Ninja School.
One is a true Genius, and the other is a guy who is extremely mediocre.
Unfortunately,
He was like Obito, an extremely mediocre Uchiha before awakening his Sharingan.
Being mediocre, after graduation, he joined a mediocre squad.
Then, after one teammate heroically sacrificed himself.
The Village then arranged for,
The current Kakashi, who could be said to be completely unsociable.
To join their team.
Following that was this tragic mission.
All his teammates died,
Leaving only himself, severely injured and close to death, and Kakashi, this Genius.
"It's actually the Naruto World. Am I lucky or unlucky?"
"Fortunately, it is now Konoha Year 45. There are still two years until the Third Shinobi World War, which is enough time for me to grow."
"After this mission, because all my teammates died, there should be a period of rest. I have to lay low from now on."
Uchiha Shin, in his heart,
After understanding this point in time.
His mind began to calculate.
The information that surged into his mind made him understand the general function of the 'Entry Extraction System'.
This System,
As long as he comes into contact with someone, he can extract their entries.
At the same time, it is a System that can increase entry levels by absorbing combat value.
At this moment, Shin directed his gaze.
Towards the panel given by the System.
Host: Uchiha Shin
Gender: Male
Age: Twelve years old
Strength: Genin
Entries: [Uchiha (White)], [Fire Release (White)], [Wind Release (White)], [Uchiha Style (White)], [Yin Release (White)].
"Tsk... what a pathetic panel. What is this called? Five White Resident?"
Uchiha Shin was truly a bit helpless.
The System had already told him.
Entries are divided into six levels.
White, Green, Blue, Purple, Gold, Red.
White is the lowest, Red is the highest.
Calculating based on this, before he awakened his past life memories, being able to live to twelve years old in the cruel Ninja World could be considered quite lucky.
"The System states that as long as there is contact, one entry can be extracted, although only once per person."
"But, this function is already very strong!"
"Combat value is the energy to upgrade entries. In my current state, I cannot acquire it, so I won't worry about it for now."
"One point I can experiment with right now is..."
Thinking of this,
He decided to take action.
The thoughts mentioned above took a long time in his mind, but in the real world, it was only an instant.
Coming back to his senses,
He pretended to cover his head and slowly straightened his body.
"Kakashi... give me some water to drink."
Hearing this, Kakashi quickly squatted down and took out a water bottle from the Ninja tool pouch on his waist.
The moment Shin took the water bottle and his hand touched Kakashi's.
He felt as though a burst of rainbow light appeared before his eyes.
Entries of Gold, Purple, Blue, Green, and White all appeared!
As expected of Kakashi!
Except for the highest level, 'Red'.
Entries of all other levels were present!
At that moment,
He wished he could extract and copy all the entries.
Unfortunately, according to the System's judgment.
Only one can be extracted per person.
Then there's nothing more to say, the Gold entry must be taken.
Having decided, his heart stirred: "System, extract!"
At that moment.
The Gold light on Kakashi's body was instantly copied and absorbed by the System.
Uchiha Shin, while pretending to drink water.
His thoughts drifted to,
The panel that only he could see.
On the panel, an entry [Genius (Gold)] had been added.
[Genius (Gold)]: Comprehension, creativity, and adaptability are greatly amplified.
At this moment, Shin's heart was filled with joy.
"Comprehension should be related to learning, creativity corresponds to Kakashi's creativity, and adaptability goes without saying."
"That's him, Kakashi, the key to earning the title of 'Five-Fifty Kakashi'."
"These Abilities, at this stage where I have no special skills, are definitely a powerful entry!"
Kakashi Hatake is indeed a monster, worthy of being a Ninja who could fight Kaguya in the later stages.
Thinking of the immense help this entry would be to him, Shin's mind stirred.
"System, install entry!"
Buzz—
A wave of understanding surged into Shin's mind.
"Is this the world of a Genius?"
Uchiha Shin felt somewhat incredible.
At this moment,
His control over Chakra.
And, from his deceased parents,
The Uchiha Style he learned.
Among them—
Shurikenjutsu, Taijutsu, Genjutsu, Throwing Techniques, Clone Jutsu, and Wire String Technique, all had a different understanding.
What he couldn't understand before, he could now understand completely.
Including elemental Ninjutsu.
Furthermore, his control over his body's spirit and reflexes had significantly increased.
It was as if he had broken free from shackles, and even his mental thoughts had become much clearer.
"The former me was a mediocre person, the current me is a Genius."
"So, is it possible... during this period of rest, to obtain Ninjutsu resources from within the clan?"
Now, he had to prepare to survive the Third Shinobi World War two years from now.
He had to make preparations!
Everything was for becoming stronger!
There's no need to think about Konoha's resources.
He was different from Obito; even without awakening his Past Life Memories.
He instinctively paid no mind to the brainwashing of the will of fire.
The Village's higher-ups,
Would not invest resources in him.
Then he could only think about how to obtain the corresponding resources from within the Uchiha clan.
While Uchiha Shin was thinking about his future path.
Kakashi, who thought his companion was fine, had long since gone to drive the ox cart.
When he saw the high walls of Konoha in the distance.
He turned his head, with that lifeless gaze.
Said to Uchiha Shin:
"Shin, we're almost at the Village."
"After this period of rest is over..."
