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

Seeing that Hoshino Yu had dodged his ninjutsu without any pressure, Orochimaru narrowed his eyes and slowly walked out of the forest outside the training ground.

"Good reaction. Now do your best to please me, Yu." Orochimaru stuck out his long tongue and licked his lips, while his golden eyes shone with a hint of fanaticism.

He had accepted this disciple for over a month, but they hadn't officially sparred yet.

This time, we want to examine more than one aspect; ninjutsu, body manipulation, genjutsu, sealing techniques, swordsmanship, and so on are all within the scope of our examination.

The purpose was to see just how strong his disciple truly was.

Because he discovered that Hoshino Yu was a bit cunning and always liked to hide things.

Upon hearing this, Hoshino Yu's smile vanished.

Why does this sound so familiar?

It seems like someone from Madara said this before. Should I reply with, "Do you want to dance too?"

However, Hoshino Yu gave up on the idea, as he did not yet have the ability to make such boastful claims.

"Teacher, you'd better be careful!"

As soon as he finished speaking, a sharp glint flashed in Hoshino Yu's eyes, and at the same time, his fingers flew, instantly forming a hand seal.

"Fire Release: Flame Bullet!"

In an instant, a huge fireball carrying scorching heat burst forth from his mouth, surging toward Orochimaru!

He started with Fire Release, displaying a style reminiscent of the Uchiha clan.

That wasn't the end of it. The moment the fireball flew out, Hoshino Yu immediately began forming hand seals again.

This level of ninjutsu might pose a great threat to genin or even ordinary chunin, but it was completely useless against Orochimaru.

The best approach is to immediately follow up with another ninjutsu to seal off the space during the brief window after using a ninjutsu technique.

"Fire Release: Fire Dragon Flame Bullet!"

As the fire dragon fire bomb, which had a larger range and more intense flames than the fire bomb, spewed out, the temperature in the entire training ground instantly soared!

Hoshino Yu was worried that the power wasn't strong enough, so he directly increased the amount of chakra supplied. As a B-rank fire ninjutsu, even Orochimaru at this moment wouldn't dare to directly withstand it with his bare body.

"Heh~ Fire Release: 1st, that's really impressive, Yu. Such a large amount of chakra at such a young age."

Orochimaru narrowed his eyes as he watched the two fire-style ninjutsu hurtling towards him, the heat waves making his hair fly wildly.

He had no intention of dodging. If he couldn't defeat a disciple who had just become a ninja head-on, what kind of teacher would he be?

Just as the fire escape technique was about to reach him, he instantly formed the Chen-Chou-Mao seals within a second.

"Water Release: Water Chaos Waves!"

The nature of the chakra within his body circulated along his meridians and began to change, and a stream of water gushed out from Orochimaru's mouth!

As the amount of chakra continued to increase, the thin stream that started out was now colliding fiercely with the two fire-style ninjutsu used by Hoshino Yu like a fierce tide!

Nourishes—

As water and fire clashed, a misty fog instantly enveloped the entire training ground.

Even a C-rank Water Release technique can unleash terrifying power in Orochimaru's hands.

"Orochimaru is still strong at this stage..." Hoshino Yu frowned slightly, and disappeared from the spot in a flash, while directly using his Observation Haki to sense the surrounding situation.

The fog would affect his vision. He didn't have red and white eye disease, but his perception of sight and hearing was no worse than the two types here.

While his current Observation Haki isn't enough to cover a large area, it's still sufficient to perceive things several miles away.

Once combined with the Rumble-Rumble Fruit and strengthened into a mental network, it will likely be within its perception range of tens of kilometers.

As for going head-to-head with Orochimaru...

Without using most of the Rumble-Rumble Fruit's abilities, going head-to-head with Orochimaru is definitely not a wise choice. Putting aside their skill levels, the amount of chakra between the two is not even in the same league.

"The surrounding area is filled with moisture, which is a good time to use 'Lightning Release'," Hoshino Yu thought to himself, then clapped his hands together, and arcs of electricity instantly wrapped around his palms.

As a genius of lightning release, I can strike a pose, clap my hands, and summon whatever I want, right?

Hand seals are auxiliary tools for chakra control, used to determine the amount of chakra, guide its flow path, stabilize its form, and change its nature.

This move is the basic skill he developed based on the Rumble-Rumble Fruit: "Electric Discharge".

Sensing that Orochimaru was still standing in the training ground, Hoshino Yu began to increase his own power output.

A flash of electricity appeared, and the water mist in the entire training ground became his electrical conductor, simultaneously emitting a crackling sound of electricity.

Orochimaru keenly sensed that a powerful electric current contained within the mist was about to engulf him, and his interest was immediately piqued.

"Lightning Release ninjutsu? That's quite an idea, Yu, but..." Orochimaru's lips curled up slightly, and his mouth slowly opened, revealing a section of a sword hilt.

After pulling the entire longsword from his mouth, he vanished from his spot in a flash.

"Hmm?" Hoshino Yu instantly sensed Orochimaru's unusual movement, immediately cut off the current output, and at the same time drew the Kusanagi sword from his back at top speed!

clang--

A sharp, metallic clang suddenly rang out. Hoshino Yu gripped the Kusanagi sword tightly, clenching his teeth and struggling with all his might against the immense force surging from the blade!

With the help of chakra and static electricity, Orochimaru's hands could hold the sword hilt without worrying about it slipping out of his grasp, but Orochimaru's strength was no joke.

Pure physical skills and swordsmanship put him under immense pressure.

Regarding illusions, when Hoshino Yu noticed a dizzying sensation in his vision, he immediately used his own electrical current to stimulate his brain nerves, thus breaking the opponent's illusion.

As the sounds of metal clashing against metal rang out, after exchanging dozens of blows, the two stood on the training ground, though their states of condition differed.

As the fog dissipated, Hoshino Yu was panting heavily, her arms trembling slightly. Orochimaru's strength was fierce, and his slashing speed was rapid and fast, leaving her breathless.

If he hadn't reacted and been faster, things would probably be much more serious than just a slight tremor in his arm.

As luck would have it, Orochimaru's sleeve got ripped open.

Although he wasn't seriously injured, a hint of surprise flashed in his eyes, and he couldn't help but laugh.

"Hehehe~ Hahaha! Is this your true strength, Yu? You've been hiding it well~"

Judging from his laughter alone, Orochimaru's laughter was genuine, which made Hoshino Yu shake his head.

"I'm not fighting anymore." Hoshino Yu pouted, stuck the Kusanagi sword into the ground, and slumped down. "Whose genin's combat test is this intense?"

"This is just a test of your practical skills; there will be plenty of tests to come."

With that, Orochimaru sheathed his sword and slowly walked toward Hoshino Yu.

"Whether it's ninjutsu, taijutsu, or genjutsu, these are all subjects of this assessment. If you fail even one of them," Orochimaru sneered, "you won't have the right to be a ninja."

"On the battlefield, the enemy won't give you advance notice."

That being said, he grew to like his disciple more and more.

Their practical skills speak for themselves; an expert's skill is immediately apparent upon seeing their work.

In terms of taijutsu and swordsmanship alone, this kid could hold his own against me for dozens of moves and even tear a hole in my sleeve without me being hurt. He could easily be a special Jonin.

His lightning release talent is also extraordinary; this is the first time I've seen him use lightning release ninjutsu without hand seals.

Without knowing about the Rumble-Rumble Fruit, he naturally assumed it was a lightning-style ninjutsu.

Seeing Hoshino Yu slumped on the grass, sweating profusely, Orochimaru squatted down and first checked his physical condition.

After finding no problems, he took out a dark-colored scroll from behind him.

"Teacher, what's this?" Hoshino Yu's eyes lit up as she looked at the scroll handed to her, and she rubbed her hands together as she took it.

Putting everything else aside, the things Orochimaru gave him were definitely not bad.

"You'll see for yourself when you see it," Orochimaru said, slowly rising as he watched Hoshino Yu's eyes light up. "You should know what you should and shouldn't learn. After you've rested up, come find me in the mission hall."

After saying that, he left the training ground without looking back.

"yes!"

Hoshino Yu responded loudly, watched the other person leave, shook his head with a light laugh, and then unrolled the scroll in his hand.

The more he examined it, the more he felt that something was wrong with the scroll.

"Forbidden technique... Forbidden technique... Ultimate technique? Flying Thunder God Technique? Multiple Shadow Clone Technique?!"

"Oh my, could this be the Book of Sealing?!" Hoshino Yu exclaimed in surprise.

Orochimaru's gift is quite generous.

The scroll isn't very big; it's probably a copy of the Book of Seals.

However, he developed his skills based on Devil Fruits and Haki, so ninjutsu wasn't very useful to him.

To take it to an extreme, one could say that domineering presence is what truly transcends everything else.

Devil Fruit abilities are equally important to Hoshino Yu.

Forbidden techniques like the Impure World Reincarnation, as well as some sealing techniques, are worth studying.

"But if I'm being asked to go to the mission hall, does that mean I'm going to start a mission...?"
