After washing his face, Uchiha Shin wiped it dry and headed to the Senju clan's training ground.
Daily training couldn't be neglected.
He took out eight shuriken from his ninja pouch and threw them using his already highly proficient Uchiha-style Shurikenjutsu.
The eight shuriken collided mid-air before all redirecting toward the wooden dummy's head.
Bang! Bang! Bang! Bang! Bang! Bang! Bang! Bang!
All eight shuriken embedded themselves into vital points on the dummy's head—the temples, the center, the back of the skull.
It was clear just how ruthless and precise Uchiha Shin's technique was.
Next, he drew a standard-issue long sword.
More accurately, it was a katana, though often simply referred to as a sword.
The moment he unsheathed it, his eyes sharpened.
Relying on muscle memory, he flipped forward and slashed diagonally, then followed up with a kick toward the target.
A blade mark appeared across the dummy's neck artery.
His kick struck the dummy's body, rebounding him into a 360-degree mid-air spin before landing perfectly.
How to put it?
Very Uchiha.
High damage, yet also full of flashy flair.
If that strike had landed on a real person, they would already be clutching their throat, dead on the spot.
Uchiha Shin's lips twitched.
The Uchiha-style swordsmanship was indeed powerful and refined, but…
As someone from the 21st century, it felt a bit… showy.
Suppressing the thought, he continued training for another forty minutes.
Afterward, he sheathed his sword.
He had controlled his strength well enough not to destroy the wooden dummy.
After all, this wasn't his own training ground.
Still, due to the sparse population of the Senju compound, he was enjoying the rare luxury of having the entire training ground to himself.
It brought him a bit of joy.
Inside the house, Uzumaki Mito activated her Kagura Mind's Eye.
In truth, she had woken up as soon as she heard the sound of shuriken earlier.
But she wanted to see how far Uchiha Shin could go in his training, so she simply observed from within.
What she saw surprised her.
His fundamentals were solid, and he was exceptionally diligent.
Nothing like the exaggerated rumors circulating outside.
It was now around 6 a.m.
Uchiha Shin estimated that Tsunade and Uzumaki Mito were probably awake by now, so he prepared to stop training.
He sat down cross-legged and began circulating the Uchiha clan's chakra extraction technique.
This technique wasn't a secret within the clan—almost everyone had it.
But it couldn't be shared with outsiders. That was the rule of major clans.
Uchiha Shin adjusted his internal chakra flow, bringing his body to its most comfortable state, then began extracting chakra from his surroundings.
This was his first time cultivating on his own since transmigrating.
He realized that chakra was somewhat like internal energy described in martial arts novels—drawn from the air and absorbed into the body through controlled breathing.
He opened his eyes.
According to the original owner's memories, chakra extraction was supposed to be difficult.
One could only extract a small amount per day.
But for him…
It didn't seem difficult at all.
Moreover, the chakra he extracted was purer and denser.
After thinking for a moment and finding no answer, he stopped dwelling on it.
He closed his eyes again and continued refining the chakra within his body.
Uzumaki Mito, meanwhile, was surprised.
"Nine-Tails, is Uchiha Shin extracting chakra?"
"But the density and quality… it shouldn't be this high."
Through Mito's perception, the Nine-Tails observed Uchiha Shin, frowning.
"Mito, he is indeed extracting chakra…"
"But this isn't something a Genin should be able to handle."
"Oh?"
"What do you mean?"
Mito was intrigued.
"That kid is extracting natural chakra… what you humans call senjutsu chakra."
"Only Tailed Beasts or those who have trained in the Sage Arts of the Three Great Sanctuaries can absorb it."
"The Uchiha have contracts with ninja cats. I've never heard of any of them mastering sage techniques."
"This kid…"
The Nine-Tails couldn't make sense of it.
A glint flashed in Mito's eyes.
Senjutsu chakra—
She didn't possess it herself, but she knew her husband had.
And as far as she knew, aside from Jiraiya, no one in Konoha currently could extract it.
If this boy could—
Then he was destined to become a powerhouse.
She had once worried whether, after her passing, anyone would protect Tsunade and Nawaki.
But now…
It seemed she needed to find a way for Tsunade to build a strong relationship with him.
Uchiha Shin spent about an hour extracting chakra.
After replacing the last traces of ordinary chakra in his body with higher-quality chakra, he opened his eyes.
Clenching his fists, he could feel his physical strength had also improved.
A smile curved his lips.
In this brutal war machine, he now had a slightly better chance of survival.
At that moment, Uzumaki Mito pushed open the door, smiling.
"Little Uchiha Shin, come quickly—breakfast is ready!"
She beckoned him over.
Uchiha Shin quickly stood up, adjusted his clothes, and bowed respectfully.
"Lady Mito, isn't this too much trouble?"
His etiquette was flawless.
Meanwhile, an ANBU hidden in the trees recorded everything by reading Mito's lip movements.
Mito glanced at the ANBU, then at Uchiha Shin, smiling.
She stepped forward, helped him straighten up, and took his hand.
"Grandma Mito knows that you and Little Tsunade are heading to the battlefield today."
"So I prepared the ingredients last night and made breakfast for you this morning."
"You must eat more later."
"Lady Mito, how can I accept this—"
Uchiha Shin tried to refuse, but no matter how he struggled, he couldn't break free from her grip.
"Little Uchiha Shin, don't be so distant. From now on, call me Grandma, just like Tsunade does."
The moment those words were spoken—
Not only was Uchiha Shin stunned,
Even Tsunade, who had just come out after getting dressed, was shocked.
Tsunade, now in her battle attire, looked at her grandmother in disbelief, then at Uchiha Shin.
What was going on?
Things were progressing this fast?
"Tsunade-sama!"
As if seeing a savior, Uchiha Shin grabbed her arm, his eyes pleading.
Tsunade was about to speak—
But Mito shot her a cold glance.
She immediately shut her mouth, carefully removed Uchiha Shin's hand, and sat down to eat.
Cold sweat broke out across Uchiha Shin's body.
He swallowed nervously.
In the end, under Mito's firm insistence, he sat down across from Tsunade, right beside Mito.
Seeing how cautious he was, Mito couldn't help but smile.
Was she really that scary?
Look at how frightened the child was.
Realizing he couldn't refuse, Uchiha Shin began eating.
At that moment, the system notification rang out—
