Because Fugaku told Asahi that the nursery in the Uchiha Clan compound wouldn't be "randomly spawning" mini azuki bean cakes for the next few days, he chose to stay home in the study and read.
(Since the bookshelves were too high, the attentive Fugaku placed all the books on the floor for his nephew to choose from. At the same time, he was so dense that he never considered whether such a small child could actually read…)
Asahi flipped through the Uchiha Chronicles, reading carefully.
Then—
He slammed the book shut!
Clutching his head, he silently screamed like a cat meme.
Argh! What is this?!
"The only reason our clan survived is because our fists are strong. Even if we lack brains, once we go mad, we can crush everyone…"
Entry after entry read the same—
Beat up some ninja clan today. Record +1.
Tomorrow, beat up a local clan in the Land of Fire and seize their territory. Record +2.
After a few peaceful days, beat up another clan. Record +3…
Then one day, they encountered a tough opponent in the Land of Fire—
And began decades of meaningless stalemate.
Finally, after a narrow defeat, they established a village together.
And because they had no brains, they were naturally targeted by everyone…
After reading such shallow records, the fact that the Uchiha survived for so many years really was thanks to their hard fists—and even harder heads.
No wonder there was a saying:
When an Uchiha faces a major setback, instead of reflecting on themselves, they first question the world.
---
Because the Uchiha Chronicles lacked any real substance—
Asahi tossed it aside.
He picked up Great Fireball Technique Operating Procedures…
And threw that away too.
Thinking back to the 720 episodes of Naruto Shippuden, the Uchiha's Great Fireball Technique had never successfully hit a single ninja.
It was practically on the same level as Amaterasu.
PS: As everyone knows, Amaterasu never actually burns anyone to death.
---
"Phoenix Sage Fire Technique."
Another one that couldn't burn anyone to death.
Thrown away.
---
"Great Fire Annihilation" felt somewhat familiar—
But since it was still Fire Release, it probably wouldn't burn anyone either.
Throw them all away.
---
Finally, realizing that the books in the Uchiha compound had almost no intellectual value—and to avoid being assimilated by so-called "ninja logic," or worse, suffering a drop in intelligence—
Asahi decided to organize everything he had learned in his previous life.
(He had no idea his actions would scare his uncle half to death.)
---
Thus—
Calculus.
Relativity.
Maxwell's equations…
Everything was scribbled haphazardly onto the blank backs of official documents Fugaku had left at home.
Thankfully, documents in the ninja world weren't double-sided—
Otherwise, Asahi wouldn't even have paper to use.
---
Due to habits from his previous life, Asahi easily entered a state of complete immersion when doing serious work.
This was exactly why his father had believed he was suited for research.
As a result, even clan members delivering meals were ruthlessly driven away by his childish voice.
A friendly tip: never interrupt a researcher mid-focus.
---
"It's time to eat."
A female clan member responsible for domestic duties came in, carrying a tray—
A bottle of warm buffalo milk, a bowl of corn and cheese porridge, and a small plate of fruit.
For a clan known for killing, the meals were surprisingly meticulous.
---
"Just leave it there. I'll eat later," Asahi replied absentmindedly, still writing.
---
As a mother of two, she naturally assumed this was a child refusing food.
So she walked over and tried to feed him.
---
"I said I can eat by myself. I don't need you to feed me."
---
When you're too weak—
Even baring your teeth only makes you look cute.
---
"Ah—"
"I said I don't want it!"
"Ah—"
Chew. Chew. Chew.
…Wait, this is kind of good.
---
After repeating this several dozen times—
The meal was finished.
---
Later, when Uchiha Mikoto came to take Asahi for his usual walk, the clan member mentioned it casually:
"Today, Lord Asahi ate less than usual. Maybe it's the summer heat? He stayed in the study all day scribbling… and didn't even say 'delicious.'"
In truth—
He had only eaten slightly less fruit than usual.
---
At first, Mikoto thought it was just poor appetite.
But when she arrived—
Asahi was still working nonstop.
---
"Asahi, today we're going to—"
She was cut off.
"No. No one interrupts me until I'm done."
He didn't even look up.
---
Mikoto grew curious.
Even for a child, this level of focus was abnormal.
---
E = mc²… S = πr²…
Formula after formula filled the pages.
Since he had already started, Asahi casually began deriving physics equations as well.
After all, math and physics are one family.
---
Mikoto: I am not worthy.
Though she couldn't understand it, she could tell—
This was advanced.
Terrifyingly so.
---
Her worldview began to crack.
This isn't talent… he didn't forget his past life at all.
So reincarnation is real…
---
Mikoto quietly drifted out of the study in a daze.
(Worldview: under reconstruction.)
---
Asahi glanced up, confused.
Why is she acting weird again?
---
He returned to work.
---
In his previous life, he had always been compared to his father.
Later, at research institutes, everyone around him had been geniuses.
He was the only one who got in through connections.
---
Now?
He didn't even realize how abnormal he seemed.
---
In a world with such a chaotic tech tree—
Surely this was fine.
After all, no one here understood science.
---
Even if they did—
They'd just think it was childish scribbling.
---
And even if he seemed strange—
He still had noble status.
No one would harm him.
---
With that thought—
His mind drifted further.
Toward something ridiculous:
Could the "Ninja World Nuclear Peace Technique" actually be theoretically possible?
---
Meanwhile, in the living room—
Mikoto was panicking.
How do I tell the Clan Head that his nephew didn't drink the "forgetfulness soup" after reincarnating…?
---
When Fugaku returned—
Mikoto rushed up, nearly in tears.
---
"What happened? How is Asahi?"
"You'll understand once you see."
---
She dragged him to the study.
---
Inside—
Asahi lay among scattered papers, frowning in deep thought.
---
Fugaku's fatigue vanished instantly.
My nephew is so cute…
---
Mikoto blushed and let go of his arm.
Then snapped:
"Look at what he wrote!"
---
Fugaku picked up a document.
Turned it over—
And froze.
---
Dense formulas filled the page.
---
What… is this?
---
At his age—
He had still been playing in the dirt.
---
Meanwhile, his nephew—
Was writing things he couldn't even understand.
---
Both Fugaku and Mikoto reached the same conclusion:
He didn't forget his past life.
---
Fugaku quickly composed himself.
So what if my kid is strange?
But this—
Must never be revealed.
---
That night—
He decided to talk to Asahi alone.
---
After finishing his work, Asahi collapsed onto the floor like a dried salted fish.
Only then did Fugaku dare approach—
Carry him to wash up—
And put him to bed.
---
Asahi climbed onto his back.
Both yawned.
---
"Why do you write these things?" Fugaku asked.
---
Half-asleep, Asahi muttered:
"I just didn't forget my past life."
---
Fugaku: …
---
"So you were very impressive before?"
---
"These are basic. Only idiots wouldn't understand them."
---
Fugaku laughed hollowly.
---
Suddenly—
Asahi covered his mouth.
---
"Will you start hating me because I'm smarter than everyone else?"
---
Fugaku immediately pulled him into his arms.
"I would never hate you."
---
Asahi kept struggling—
Still in full brat mode.
---
"Don't bite—"
Too late.
---
"OW!"
---
"You're so naughty! You don't act like an Uchiha at all!"
---
"Hehehe…"
---
Fugaku gave up.
"Go to sleep."
---
That night—
Fugaku checked his temperature.
Then poked his cheek.
---
"Such a cute face… why such a troublesome personality?"
---
Smack.
Asahi slapped his hand away.
---
Fugaku smiled faintly.
---
In the living room, he wrote everything down—
On a special talisman.
Then burned it.
---
Perhaps only the heavens knew the truth.
---
Fugaku concluded—
Asahi's brilliance must be a gift from the divine.
