Naruto: Copy System

Dawn broke, painting the sky with hues of orange and pink as Shin opened his eyes.

"Another day, another chance to grind. Time to refine some chakra." Shin sat up and began his morning ritual.

He had only received the [Chakra Refinement Technique] a week ago. It was a standard issue scroll provided by the clan.

Despite being ostracized due to his parentage, Shin still received the basic necessities. Things like a living allowance, the [Chakra Refinement Technique], and even those two sealing jutsu from yesterday.

The [Adamantine Sealing Chains] and the [Four Symbols Seal] were prized even within the Uzumaki Clan; most elite Jōnin could only dream of learning them.

Chakra was the fusion of physical and spiritual energy extracted from the 130 trillion cells in the human body. Overdoing it could lead to fatigue or even worse, risking one's life.

Shin spent an hour refining chakra. Despite being only five years old and a newbie to chakra refinement, the amount he generated was startling.

Thanks to his [Perfect Sage Body], the quality and quantity of his chakra were several times greater than that of a normal Sage Body.

Sensing the energy coursing through him, Shin figured his chakra reserves were probably on par with a Jōnin.

And this was just the beginning. If he kept refining his chakra for a few years, could he reach Tailed Beast levels?

He thought of Hashirama, the man who wielded chakra like it was an infinite resource, even the Nine-Tails paling in comparison.

Shin got up, washed up, and prepared breakfast.

"Kushina, breakfast is ready! Snooze, you lose!"

A while later, Kushina emerged from her room, yawning, her usually silky red hair a tangled mess.

"Go wash up, sleepyhead. Breakfast is getting cold. And look at your hair, birds could build a nest in there."

Shin reached out and gently combed his fingers through Kushina's hair. Her face flushed slightly, but she was used to Shin's casual touch.

After washing up, Kushina took her seat at the table.

Shin had prepared a feast: fish, meat, and two large glasses of milk.

Being a shinobi was energy-intensive; they couldn't skimp on nutrition. Proper fuel was essential for training.

Both Shin and Kushina had healthy appetites, so Shin had prepared enough food for five people.

Thankfully, the Uzumaki Clan provided a generous allowance, and Shin supplemented their income by hunting in the forest. Otherwise, they'd be struggling to keep their bellies full.

"Kushina, after breakfast, it's training time. You're coming with me."

Shin said as he ate. As a transmigrant, he knew the dangers of the Naruto world.

He wanted Kushina to become stronger, to be able to protect herself.

Kushina nodded. Staying home alone was boring; she'd rather train with Shin.

After breakfast, Kushina took the initiative to wash the dishes. While she was busy, Shin opened his system interface and accepted the only mission on the quest board.

He hadn't accepted it yesterday, but there was no point delaying. It was a mission he had to complete no matter what.

Once Kushina finished with the dishes, they headed out to the nearby forest.

"Kushina, you work on refining your chakra," Shin instructed.

"Okay." Kushina sat on a clean rock and started the monotonous process of chakra refinement.

Shin took out his weighted clothing and put it on. Then, he drew the short blade from his hip and began practicing his swordsmanship.

Before he got the [Chakra Refinement Technique], Shin had focused on Kenjutsu and Taijutsu.

With his [Perfect Sage Body], his physical strength was exceptional, making taijutsu training twice as effective. The Uzumaki and Senju were natural-born brawlers.

It was just that the Uzumaki Clan prioritized sealing jutsu, neglecting their powerful physiques.

After a thousand swings, Shin wiped the sweat from his brow and took out his kunai and shuriken.

Fifty meters away, he had set up a target. It was crude, but it served its purpose.

Shin focused, his black eyes morphing into a blood red, a single black tomoe swirling into existence.

The target, which had been a small speck at fifty meters, was now crystal clear.

The [Sharingan], a One-Tomoe Sharingan.

Shin had Uchiha blood flowing through his veins; awakening the [Sharingan] wasn't surprising.

He had awakened it when his mother died, but he had kept it a secret, even from Kushina.

The fewer people knew, the better. If others found out he had the [Sharingan], his life within the Uzumaki Clan would become even more difficult.

Fixing his gaze on the distant target, Shin launched a kunai. With the [Sharingan]'s enhanced vision, he could clearly see the bullseye.

The kunai struck dead center, its force so strong that it pierced through the target, leaving a gaping hole.

After practicing kunai throwing for a while, Shin decided to move on. Compared to kunai throwing, mastering jutsu was far more critical.

"Next up, time to crack this sealing jutsu."

Shin pulled out the jutsu scroll and started studying the [Adamantine Sealing Chains]. He wasn't in a hurry to learn the [Four Symbols Seal]; that could wait.

Mastering the [Adamantine Sealing Chains] would significantly boost his combat power, giving him a way to utilize his massive chakra.

After all, what good was a mountain of chakra if you didn't have the jutsu to use it effectively?

Shin had figured out some basic chakra control techniques, like channeling it to his legs for explosive jumps, propelling him several meters into the air.

That's how he had been leaping onto trees, but his self-taught techniques were rough around the edges.

Not only did they guzzle chakra, but they also put a strain on his legs. He was lucky to have a [Perfect Sage Body]; a normal person attempting those jumps might end up crippled.

"What I need are the fundamentals."

Shin tried to use the [Adamantine Sealing Chains], but nothing happened. He realized he didn't have the fine motor control needed to manipulate his chakra effectively.

Despite his vast reserves, he couldn't achieve the precise control needed to channel chakra for complex jutsu.

How could he learn the [Adamantine Sealing Chains] with such poor chakra control? He needed to master the basics first.

Tree Climbing and Water Walking immediately came to mind. He had to start somewhere, and refining his chakra control was paramount.

Under Kushina's surprised gaze, Shin began his tree climbing training. He had assumed it would be a piece of cake, but it turned out to be more challenging than he anticipated.

"Turns out having too much chakra can be a pain."

The more chakra he had, the harder it was to control. It seemed there was a trade-off to everything.
