Xingyu's Sharingan

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

"Another new day. Time to refine chakra first." Shin sat up and began to refine his chakra.

The chakra refinement technique was something Shin had obtained only a week ago, provided by the clan.

Although Shin was ostracized within the Uzumaki Clan due to his status, he still received the essentials.

This included his living allowance, the chakra refinement technique, and even the two sealing jutsus he had obtained yesterday.

Adamantine Sealing Chains and Four Symbols Seal were extremely precious even within the Uzumaki Clan; even average elite jonin could not learn them.

Chakra is energy produced by perfectly fusing physical energy, extracted from the trillions of cells in the human body, with spiritual energy. Therefore, one should not over-refine it, or it could lead to physical exhaustion at best, or life-threatening danger at worst.

Shin refined chakra for an hour. Although he was only five years old and had only been refining chakra for seven days, the amount of chakra within his body was somewhat frightening.

With his Perfect Sage Body, the chakra he refined was several times stronger than that of a standard Sage Body in both quality and quantity.

Feeling the chakra within him, Shin felt that his chakra reserves should be no worse than those of a jonin.

And this was only after a short time of refining. If he were given a few years, would his chakra reserves rival those of a Tailed Beast?

Thinking of Hashirama, whose chakra seemed as if it were infinite—even the Nine-Tails' chakra could not compare to his.

After getting up, Shin washed up and prepared breakfast.

"Kushina, time to eat. If you're late, there won't be any left for you."

A while later, Kushina emerged from her room, yawning, her once-silky hair as messy as a bird's nest.

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

Shin reached out to smooth her hair. Kushina's face flushed slightly when she noticed his action, though she was already used to it.

After washing up, Kushina sat at the dining table.

The breakfast Shin prepared was very hearty, with fish, meat, and two large glasses of milk.

After all, they were ninjas, and training consumed a lot of energy, so they couldn't skimp on food; they had to replenish enough nutrients.

Shin and Kushina had large appetites, so the breakfast Shin prepared was enough for five people.

Fortunately, the living allowance provided by the Uzumaki Clan was generous, and Shin would also hunt in the forest; otherwise, they wouldn't even be able to afford their meals.

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

Shin said to Kushina while eating.

As a transmigrator, Shin understood the trajectory of this world and knew just how dangerous the Naruto world truly was.

He wanted Kushina to be stronger so that she would have the ability to protect herself.

Kushina nodded. It would be boring for her to stay home alone while Shin trained, so she might as well go with him.

After the meal, Kushina took the initiative to wash the dishes. While she was busy, Shin opened his system panel and accepted the only mission available.

He hadn't accepted it yesterday, but he decided to take it today; he would have to complete it regardless.

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

"Kushina, start refining your chakra," Shin said to her.

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

Shin took out the weights he had fashioned. After putting them on, he drew the short blade at his waist and began to swing it.

Before he had obtained the chakra refinement technique, Shin had been practicing swordsmanship and taijutsu.

With his Perfect Sage Body, his physique was incredibly powerful, making his taijutsu training twice as effective with half the effort. It could be said that both the Uzumaki Clan and the Senju Clan were excellent candidates for taijutsu.

It was just that the Uzumaki Clan focused all their attention on sealing jutsus, neglecting their own powerful physiques.

After swinging his blade a thousand times, Shin wiped the sweat from his forehead and took out his throwing weapons—kunai and shuriken.

Fifty meters away stood a target Shin had made. Although it was crude, it was still functional.

His gaze sharpened, and his pitch-black eyes turned blood-red, with a single black tomoe appearing in each.

The target, which had looked small from fifty meters away, was now perfectly clear in his vision.

Sharingan. A single-tomoe Sharingan.

Shin possessed the bloodline of the Uchiha Clan, so it was not strange that he could awaken the Sharingan.

He had awakened it when his mother in this life passed away, but he had kept it hidden ever since; even Kushina didn't know.

The fewer people who knew about this, the better. If others found out he possessed the Sharingan, his life within the Uzumaki Clan would become even more difficult.

Staring at the distant target, Shin threw the kunai in his hand. Because of the Sharingan, he could clearly see the center of the target in the distance.

The kunai struck the dead center of the target, its immense force piercing straight through and leaving a gaping hole in its wake.

After practicing for a while, Shin set aside his kunai throwing drills; after all, ninjutsu training was far more important than mere projectile skills.

"Next, it's time to study sealing techniques."

Shin pulled out a ninjutsu scroll and began to study the Adamantine Sealing Chains. He wasn't in a rush to tackle the Four Symbols Seal; that could wait for another time.

If he could master the Adamantine Sealing Chains, it would significantly boost his combat prowess, finally giving his massive chakra reserves a proper outlet.

After all, no matter how powerful one's chakra might be, it was useless if one lacked the ninjutsu to unleash it.

Shin had managed to develop a few chakra manipulation techniques on his own, such as channeling it into his legs to burst forth, allowing him to leap over a dozen meters into the air.

The way he had jumped into the trees earlier was using this very method, though his self-taught techniques were incredibly crude.

Using them not only consumed excessive amounts of chakra but even risked injuring his legs. Fortunately, Shin possessed a Perfect Sage Body, so he remained unharmed; if anyone else tried this, they would likely end up crippled.

"What I lack right now are simple, fundamental techniques."

Shin attempted to perform the Adamantine Sealing Chains, but he couldn't manifest it at all. It was only then that he realized he couldn't command the chakra within his body with the ease of moving his own limbs.

Though his chakra was vast, his inability to control it with precision made even the act of mobilizing it difficult.

Under these circumstances, how could he ever learn the Adamantine Sealing Chains? It seemed he would have to master precise chakra control first!

Shin immediately thought of tree-climbing and water-walking. He was a man of action, and since controlling his own chakra was a matter of great importance, he could not afford to be careless.

Under the surprised gaze of Kushina, Shin began his tree-climbing training. He had originally assumed it would be simple, but once he started, he discovered the true difficulty of the task.

"I'm suddenly realizing that having too much chakra isn't necessarily a good thing."

The more chakra one possessed, the harder it was to train. There was no helping it; one had to take the rough with the smooth.
