I'm in Naruto, but the system says I'm in One Piece.

I learned from the tavern owner that this so-called "Zoro" should be Rope Tree, but judging from Water Pillar's reaction, the two should not know each other.

How come the mission was successful so quickly?

Hoshino Yu pondered for a moment, then decided to stop thinking about it.

This system isn't new, so let's just leave the attribute points as they are.

I just don't know when I'll develop Armament Haki.

Hoshino Yu definitely wants to have complete control over the three types of Haki.

Besides Observation Haki, the core function of Armament Haki is to enhance offense and defense, break through Logia-type elemental transformations, and advance internal destruction. It can transform mental energy into invisible armor, greatly increasing combat power.

His goal was to imbue his weapon with domineering energy, enhancing its sharpness and destructive power.

But now that I have no other options, I can only rely on mission rewards to make a living.

After a moment's thought, Hoshino Yu looked at his personal attribute panel.

[Name: Hoshino Yuu]

Age: 6

Chakra level: 1.9 (low amount)

【五维：力1.5/速1.6/体1.7/精6.1/印1.1】

Chakra Properties: Lightning, Water, Fire, Yin, Yang

......

[Assignable attribute points: 0.4]

"Hmm, we already have an attribute value of 0.4, but the road ahead is long and arduous..."

After glancing at the attribute panel, his gaze fell on the Yin and Yang attributes of chakra.

I seem to have forgotten about the development of these two methods.

Leaving aside the Yin Release chakra for the moment, the strength of their mental power is undeniable, so there's no need to focus on it.

This is why he was able to quickly adapt to Observation Haki and master a small amount of genjutsu.

It seems that my progress in cultivating Yang Release chakra hasn't been very significant.

That thing can enhance physical functions, especially if one can achieve yin and yang harmony.

Hoshino Yu took the Kusanagi sword off his back and placed it beside him, then lay down on the grass and quietly gazed at the sky.

He had also considered things like Sage Mode.

Mount Myōboku, Ryūchi Cave, and the Forest of Corpses—these are the three great sacred sites of the ninja world.

At present, only Jiraiya has gone to Mount Myōboku for training. If he wants to come into contact with the immortal realm in the future, he will inevitably have to deal with them.

Natural energy does not only exist in the three immortal lands, but permeates the entire world.

What he was considering was whether he could use this as a basis to create his own version of the Thunder God Mode or something.

As for where to train, it must be the Land of Thunder.

The area is frequently struck by lightning, and since he is a user of the Rumble-Rumble Fruit, it is a perfect fit for his training.

Later on, when facing the Otsutsuki, the addition of Sage Mode will make the battle much easier.

The development level of the Rumble-Rumble Fruit is not very high at present, but some practical skills have already been developed.

Electric discharge, thunderbirds, thunder beasts, and thunder metallurgy are all at least as powerful as ninjutsu.

Regarding Thunder Dragon, Ten Thousand Thunder, Thunderclap, etc., Hoshino Yu said that the fruit's development level is not high, and he doesn't understand it for the time being.

As he pondered, he sensed two figures slowly approaching him, one of which was a water column.

"Hmm? School shouldn't be over yet at this hour," Hoshino Yu raised an eyebrow, sat up, and looked in the direction the other person had come from. "Could it be that they skipped class?"

After waiting a moment, as two figures appeared in the distance, he immediately recognized who they were with his current eyesight.

The other person had short, light brown hair, thick eyebrows, amber eyes, and slightly tanned skin. He wore a navy blue long-sleeved shirt and exuded an extremely strong sense of youthful agility.

Tsunade's younger brother, Nawaki.

A tragic character who has the looks of a protagonist but not the fate of one.

"How did they end up together?" Hoshino Yu asked curiously.

Judging from his age, Rope Tree should be in the fourth grade, which reminded him of the system task he had just completed.

"No wonder the mission was completed so easily; they were just playing together, huh~"

At the same time, of the two people who were rushing over, Shuizhu was the first to keenly notice his presence.

"Yu?!"

When their eyes met, Shui Zhu, who should have been happy, was slightly stunned.

"Something feels different than before..."

Suppressing his doubts, he turned back and called out to Rope Tree:

"Napaki, it's Yuu!"

"Yu?" Nawaki was taken aback upon hearing this, then suddenly realized what she meant and exclaimed in a high-pitched voice, "Isn't that the genius kid who graduated at six?!"

"Yes, yes, it's him, my friend, Hoshino Yu!"

The two quickened their pace and soon arrived in front of Hoshino Yu.

"Yo, Water Pillar-senpai, you skipped class to come out?" Hoshino Yu slowly stood up, looking at the two who were panting, and said with a hint of teasing.

Upon hearing this, the water column grinned, showing off its large white teeth, scratched its head, and laughed:

"I have to skip classes! You've already graduated early, I need to step up my game too! Otherwise I'll fall behind!"

Seeing that Hoshino Yu still liked to joke around as usual, Mizuhashi's doubts faded considerably, and he realized that he had been overthinking things.

However, if Minato were here, he would definitely be able to keenly perceive the changes that have occurred in Hoshino Yu.

That's the kind of ferocity that only appears after someone has killed someone.

"This is..." Hoshino Yu looked at Nawaki and asked, pretending not to recognize him.

"Oh, this is a rope tree!"

Nawaki stared at Hoshino Yu as if he had seen a rare summoned beast, and after a while he finally spoke:

"You're that genius ninja who graduated early?"

"Yes."

Hoshino Yu looked at the other person, and began to ponder again.

It is currently Konoha year 33, and Nawaki is a fourth-year student, which means he has two years left before graduating and becoming a genin. At that time, he will receive his sister Tsunade's death pendant, become Orochimaru's disciple, and then be blown up by an explosive tag trap.

I had previously heard Orochimaru say that his friend Tsunade wanted him to help her take Nawaki as her disciple, but he has not yet given a reply.

What if Orochimaru really takes him in later?

Is Orochimaru about to mutate?

Hoshino Yuu wanted to make some changes, after all, the other person was now her teacher.

Aside from being a bit aloof, he never shortchanges anyone in his dealings with others.

Why not give Rope Tree a good beating first, so that he knows that rushing forward with only hot blood is useless?

Just as he was pondering, the rope tree in front of him suddenly shouted out in a loud and boisterous manner:

"Yu, I want to have a match with you!"

As he spoke, he put one hand on his hip, raised the other hand, pointed at him, and shouted:

"Let me see what this genius really is all about!"

"Rope Tree..."

"Never mind the water pillar. Challenging the strong is my belief." Nawaki looked at Hoshino Yu, a fierce determination burning in his eyes, and shouted, clenching his fist, "I'm going to be the Hokage!"

"No," a glint of light flickered in Shui Zhu's eyes, "I mean, I want to take on the challenge too."

Looking at the two immature kids in front of him, Hoshino Yu curled his lip.

Nawaki, do you also want to be the one behind Minato?

There's also a water jet; it seems to want to challenge itself too.

If we get another Kakarot...

But looking at it this way, he really does seem like the protagonist of a shonen anime.

No wonder she can get along with the water column; she's definitely got the makings of a protagonist.

"Alright," Hoshino Yu rubbed his fist and said with a light laugh, "Then you can all come at me together!"

A moment later.

Shuizhuo and Rope Tree both covered their faces and lay on the ground, wailing in turn.

"Yu, you're too strong! I can't beat you at all!" Mizuki said helplessly as he looked at Hoshino Yu's figure.

"Damn it! You can hit me all you want," Rope Tree wailed, "but don't go after my handsome face!"

Hoshino Yu crossed his arms, slowly sat down cross-legged, and said with a smile:

"That's not my fault. You all collapsed before I even exerted any effort."

It doesn't take much effort to beat two children.

If you really want to test your own strength, you have to fight someone at the Jonin level.

Why don't you go and practice with Danzo and see how sharp the kunai that pierced Susanoo is?
