Shin's Sharingan

At dawn, as the sky was just beginning to brighten, Shin opened his eyes.

"Another new day. I'll start by refining my chakra." Shin sat up and began refining his chakra.

Shin had obtained the Chakra Refinement Technique a week ago. It was the technique issued by the clan.

Although Shin was shunned by the Uzumaki Clan because of his identity, he still received the things he was entitled to.

For example, living expenses, the Chakra Refinement Technique, and even the two Sealing Jutsu he had received yesterday.

The Adamantine Sealing Chains and the Four Symbols Seal were extremely precious even within the Uzumaki Clan. Most Elite Jonin couldn't learn them.

Chakra was energy drawn from the body's millions of cells and produced by perfectly combining physical energy with spiritual energy. It shouldn't be refined excessively, or the consequences could range from fatigue to death.

Shin spent an hour refining chakra. Though he was only five years old and had been refining chakra for just seven days, the amount inside him was already astonishing.

With the Perfect Sage Body, the chakra he refined was several times greater than that of someone with a Sage Body, in both quality and quantity.

Feeling the chakra inside him, Shin

thought his reserves probably weren't inferior to a Jonin's.

And he'd only been refining chakra for a short time. If he had a few years, would his reserves rival those of a Tailed Beast?

Just look at Hashirama. His chakra seemed practically limitless. Even the Nine-Tails' chakra couldn't compare to Senju Hashirama's.

After getting up, Shin washed up and prepared breakfast.

"Kushina, breakfast is ready. If you're late, there won't be any left for you."

A while later, Kushina came out of her room, yawning. Her usually smooth hair was as messy as a bird's nest.

"Go wash up. Breakfast is ready, or it'll get cold. Look at your hair—birds could build a nest in it."

Shin reached out and smoothed Kushina's hair. When she noticed, her cheeks turned faintly red, but she was already used to it.

After washing up, Kushina sat down at the table.

Shin had prepared a generous breakfast, with fish and meat, as well as two large cups of milk.

After all, they were ninja, and training took a lot out of them. They couldn't skimp on food; they needed plenty of nutrition.

Shin and

Kushina had big appetites, so Shin had prepared enough breakfast for five people.

Fortunately, the Uzumaki Clan provided them with enough living expenses, and Shin also hunted in the forest. Otherwise, they wouldn't have been able to afford their meals.

"Kushina, I'm going to start training after breakfast. You should come with me."

Shin spoke as he ate.

As someone who had crossed over into this world, Shin knew how events would unfold in the Naruto World and just how dangerous it was.

He wanted Kushina to become stronger too, so she could protect herself.

Kushina nodded.

Shin was going to train, and staying home alone would be boring. She might as well go train with him.

After eating, Kushina volunteered to wash the dishes. While she was busy, Shin opened the system panel and accepted the only mission listed.

He hadn't accepted it yesterday, so he decided to do it now. He had to complete it sooner or later anyway.

Once Kushina had finished washing the dishes, Shin went out with her and headed to the nearby forest.

"Kushina, refine your chakra," Shin told her.

"Okay." Kushina sat on a clean rock and began the tedious task of refining chakra.

Meanwhile, Shin took out the weights he had made and strapped them on. Then he drew the short blade at his waist and began practicing his swings.

Before he obtained the Chakra Refinement Technique, Shin had spent all his time practicing swordsmanship and Taijutsu.

With the Perfect Sage Body, he was physically powerful, making Taijutsu training twice as effective. The Uzumaki and Senju Clans were both naturally suited to Taijutsu.

But the Uzumaki Clan focused all its attention on Sealing Jutsu and neglected its powerful physiques.

After swinging his blade a thousand times, Shin wiped the sweat from his forehead, then took out his Kunai and Shuriken, along with his other throwing weapons.

Fifty meters away stood a target Shin had made. It was rather crude, but it still did the job.

Shin's gaze sharpened. His dark eyes turned bloodred, and a black Tomoe suddenly appeared in each.

The target, which had looked tiny from fifty meters away, now appeared crystal clear.

The Sharingan—a One-Tomoe Sharingan.

Shin had Uchiha Clan blood, so it wasn't strange that he could awaken the Sharingan.

Shin's Sharingan had awakened when his mother in this life died, but he had kept it hidden ever since. Even Kushina didn't know.

The fewer people who knew, the better. If others found out Shin had the Sharingan, life in the Uzumaki Clan would become even harder for him.

Keeping his eyes on the distant target, Shin threw the Kunai in his hand. With the Sharingan, he could see the target's center clearly.

The Kunai struck the very center of the target. Its powerful force sent it straight through, leaving a hole behind.

After practicing with the Kunai for a while,

Shin stopped. Compared to throwing Kunai, learning Ninjutsu was more important.

"Next, I should study Sealing Jutsu."

Shin took out a Ninjutsu Scroll and began studying the Adamantine Sealing Chains. There was no rush to learn the Four Symbols Seal; he could study it later.

If he learned the Adamantine Sealing Chains, his combat strength would increase considerably, and he'd finally have a use for his enormous chakra reserves.

After all, no matter how much chakra he had, it was useless if he couldn't use Ninjutsu.

Shin had worked out a few ways to use chakra himself. For example,

he could gather it in his legs and release it in a burst to leap more than ten meters into the air.

That was how Shin had managed to jump into the trees earlier, but the technique he'd come up with was crude.

It consumed too much chakra and could even injure his legs. Fortunately, Shin had the Perfect Sage Body and would be fine. Anyone else who tried it might end up crippled.

"What I'm missing are some simple techniques."

Shin tried to use the Adamantine Sealing Chains, but nothing happened. Only then did he realize he couldn't control the chakra inside him as if it were an extension of his own body.

He had plenty of chakra, but he couldn't control it precisely, making it difficult even to direct it where he wanted.

How could he learn the Adamantine Sealing Chains like this? It seemed he needed to learn precise chakra control!

Shin immediately thought of Tree Climbing and Water Walking. He was determined to try them. Controlling his chakra was crucial, and he couldn't afford to be careless.

With Kushina watching in surprise, Shin began practicing Tree Climbing. He'd assumed it would be simple, but once he tried, he realized how difficult it was.

"I'm starting to realize that having too much chakra isn't necessarily a good thing."

The more chakra he had,

the harder it was to practice. There was nothing he could do; every advantage came with a drawback.
