Naruto: I'm really not an evil scientist!

Don't be fooled by the lack of dazzling special effects and light shows in this melee combat; it is actually far more dangerous and brutal than the previous battles, with every move and every stance a matter of life and death.

The Nine-Tailed Gundam, wielding the Heart Sword Amazu Spear, clashed with the Susanoo Gundam, wielding the High Vibration Particle Blade, on the turbulent sea.

The Heavenly Swamp Spear, which resembles a DNA helix, is called the Heart Sword. It is an extremely special creation of the mind—the stronger the heart, the harder the sword. It is one of the strongest powers that the Sage of Six Paths bestowed upon Naruto, and it is also a wonderful application of Yin-Yang Release and Truth-Seeking Balls.

In the manga, Obito Uchiha mastered this power after becoming the Ten-Tails' Jinchuriki. Unfortunately, his will was not strong enough. Under Naruto's persuasive talk, he failed the judgment test, his heart softened, and the sword weakened and shattered completely.

But Naruto is different. Although he can be as naive as a child at times, his determination to defeat Sasuke is exceptionally strong.

Whether it was to protect Konoha or to prove himself, he never wavered in his determination to defeat Sasuke.

This unwavering belief made the Heavenly Swamp Spear incredibly strong, like an indestructible divine weapon.

At the same time, the Amatsu Spear also possesses the passive attribute of the Truth-Seeking Ball, which can decompose all matter. If an ordinary person encounters it, even the slightest bump or knock will cause them to instantly turn into dust.

Sasuke's high-vibration particle light blade is a massive ship-slaying blade made entirely of iron sand. The blade is covered with a layer of purple Susanoo chakra membrane, mixed with a layer of greenish Sage chakra, just like a perfect combination of a high-frequency sword and a beam saber from the Gundam series.

From a scientific perspective, regardless of the material, it is inherently non-uniform, a fact that can be clearly seen in its microstructure.

Therefore, when high-frequency vibrations of several kilohertz are applied to a material, the vibration amplitude will produce very subtle differences in areas of non-uniformity.

Because high-frequency weapons operate at extremely high frequencies, they can instantly cause these tiny, uneven vibrations to accumulate rapidly, reaching the fatigue limit of the material. Combined with the cutting action of the weapon itself, this allows them to easily cut through the material.

The best way to defend against high-frequency weapons is to use elastic materials, but if the frequency exceeds the elastic limit, it will still be damaged.

Therefore, in theory, Sasuke's high-vibration particle light blade, which he wields by combining scientific knowledge, is indestructible and can cut through anything, provided that the vibration frequency is high enough.

On the sea surface, there was a sudden clattering sound and sparks flying everywhere.

Naruto and Sasuke were like two equally matched foes, their battle igniting a fierce and terrifying spectacle.

The two fought for more than fifty rounds, but neither could gain the upper hand, and neither could completely defeat the other.

Finally, after a collision that could be described as earth-shattering, the two were each thrown back dozens of meters, temporarily creating distance between them.

That makes sense. Naruto's heart was strong enough, so the black Tenma Spear was hard enough. Sasuke's sword was made of countless tiny iron sands, so there was no question of whether it would break or not. In addition, with the effect of Sage Chakra resisting the Truth-Seeking Balls, Sasuke was simply cutting Naruto's Spiral Tenma Spear at high frequency.

"Huff huff huff... Pretty capable, bottom of the barrel!" Sasuke gasped for breath, large beads of sweat rolling down his forehead like rain. Under extreme mental fatigue, his body trembled slightly, and he appeared in a listless state similar to "kidney deficiency".

In order to make his sword sharp enough to cut Naruto's Ama-no-Numa Spear, Sasuke gritted his teeth and increased the vibration frequency, while also concentrating to ensure that Sage Chakra could accurately cover the blade to counteract the corrosive effect of the Truth-Seeking Balls.

Although the process does not consume a lot of chakra, the mental fatigue caused by such high-intensity, meticulous operation is far beyond what ordinary people can imagine.

Fortunately, constantly refining Sage Chakra makes one more energetic the more one uses it, like lighting a lamp in the darkness, which is why Sasuke was able to barely hold on.

"There's a limit to bravado. Give up, Sasuke. Although it's an unfair victory, you can't possibly defeat me and destroy Konoha in your current state."

Compared to Sasuke, who was already somewhat "kidney-deficient," Naruto Uzumaki remained completely calm and composed, his breathing as steady as a still lake, seemingly without any signs of fatigue.

Seeing Sasuke's poor condition, Naruto felt a pang of worry and kindly offered him some advice.

Of course, the Heart Sword requires the user to imbue the sword with their own power of belief, which takes just as much to Naruto's liking as it does for Sasuke.

However, compared to Sasuke, who shares Kakashi's "kidney deficiency," Naruto is naturally energetic, so this kind of exertion is like a drizzle to him and not worth mentioning at all.

Therefore, although the two appear to be evenly matched, the scales of victory have already quietly tipped in Naruto's favor.

In fact, Naruto didn't even use the Rinnegan's abilities or his exclusive eye technique, Amenotejikara, which is the same eye technique Sasuke uses in the manga.

That's right. With the massive amount of chakra transferred by the Sage of Six Paths, Naruto awakened the Rinnegan with six tomoe, and the eye technique he obtained was the same as the Amenotejikara that Sasuke obtained in the original manga.

In fact, the Sage of Six Paths originally did not want to interfere in the affairs of the ninja world, just like a hermit who transcended the mortal world.

Two months ago, the seal on the moon loosened, and a month ago, his mother Kaguya was completely unsealed, causing chaos in the ninja world. That's why he had to step forward and give Naruto a boost of power to prevent his rampaging mother from destroying the world.

As for why he passed the torch to Naruto but not Sasuke, it's because he's showing favoritism towards Ashura again.

Chapter 263 Fusion and Transformation!

The main reason is that Sasuke and Hiruko got too close, and Hiruko was closely related to the unsealing of their mother.

For this reason, the Sage of Six Paths has not yet given Sasuke a power-up.

If it weren't for Hiruko's influence, he actually wanted to pass on the same power to his two reincarnated sons, just like in the manga, to see if he could reconcile the chakra of his two foolish sons as the hosts came to terms with each other.

However, due to Hiruko's presence, the Sage of Six Paths could only pour as much power into Naruto as possible, to the point that it was almost overflowing.

However, because the power was given too much, Naruto was unable to control it effectively, and even his daily life was affected. Naruto had to ask Mito Uzumaki, Tsunade's grandmother, to help him seal some of the power with a sealing technique.

Even so, Naruto sometimes still couldn't completely control the violent power within him.

However, the one-time Yin-Yang power used for sealing was not passed on for the time being. Hagoromo Otsutsuki wanted to give it to Naruto when sealing Kaguya. However, a month passed and he found that his mother did not seem to have any intention of coming down from the moon to the ninja world. He could only continue to wait in the ninja world with a lot of questions.

After all, what was wandering in the ninja world was just a wisp of chakra left behind by the Sage of Six Paths; he himself was not actually in the ninja world.

Moreover, he felt it was inappropriate to investigate the Moon Feather Robe, which now seemed to have become his mother's bedroom. It wasn't that he lacked the ability, but rather that the mother-son relationship was somewhat awkward.

Perhaps my mother has regained her former gentleness, but I hope she doesn't go berserk and go crazy again when she sees me.

Therefore, unless his mother destroys the world first, he doesn't really want to bother her.

He could only stay in the ninja world, first acting as an old man to Ashura's reincarnation, passing on some power, then teaching him some Six Paths Sage Techniques and how to use Truth-Seeking Balls, while also observing the situation.

In fact, if Naruto had used Amenotejikara to swap positions with the iron sand surrounding Sasuke's Susanoo during the battle, and had then launched a Tailed Beast Ball close to Sasuke's face along with a piercing attack from the Amenotejikara Spear, Sasuke would have been certain to die.

The main reason is that deep down, Naruto always felt that his cheating was somewhat unfair, and he felt a little embarrassed about it.

Moreover, he never intended to kill Sasuke; in his heart, Sasuke was an extremely important person.

The reason he repeatedly challenged Sasuke to battle was simply because he wanted to understand each other's true feelings through this intense duel.

He thought that it would be great if Sasuke could vent his anger and resentment in battle, and ideally, Sasuke could fight until he was exhausted, so that he wouldn't cause trouble every few days and disturb the peace of the village.

Of course, Naruto himself also somewhat enjoyed the process of fighting Sasuke, that kind of visceral, bone-crunching combat.

The tension and excitement of the back-and-forth battle, and the exhilaration of going all out against his best friend, all secretly excited him, but he was too stubborn to admit it no matter what.

"Do you think you've already won, Naruto!" After a few breaths, under the nourishment of Sage Chakra, Sasuke's symptoms of kidney deficiency caused by overexertion gradually eased.

He felt his strength return and immediately felt invincible again, shouting at the top of his lungs, his voice full of defiance and provocation.

"Hmph, why not use the power of the Rinnegan?" Sasuke scoffed, his face full of disdain as he questioned, "Do you think that the power of the Nine-Tails and the Truth-Seeking Balls alone is enough to defeat me? You're too arrogant, Naruto! Don't think you can underestimate me just because of that!"

“This…” Naruto looked at Sasuke, who was clearly exhausted but still stubbornly persevering, and couldn’t help but feel a headache coming on.

He scratched his head and explained helplessly, "These Rinnegan eyes evolved from your eyes, Sasuke. It feels weird to use the power of these eyes to defeat their former owner. It's like I stole something from you and then used it against you."

Although Naruto is also a "debt king" who likes to borrow various powers, he still feels a little embarrassed about using borrowed power to defeat the original owner.

Although Naruto is shameless in some ways, he would never do such a thing unless absolutely necessary, especially since Sasuke has special significance to him, and he really doesn't want to resort to such methods.

In terms of raw strength, Naruto didn't completely overwhelm Sasuke if he hadn't relied on various tactics to kill him at first sight.

Both sides had similar output capabilities, but compared to Sasuke, who was weak and exhausted at this time, Naruto's source of power was far too abundant, like a spring that kept flowing, inexhaustible.

"Foolish! Whatever the source of power may be, as long as you truly control it, that power is your own!"

"Bring it on, Naruto! Let me see your full power! The power that bastard Sage of Six Paths gave you can't be limited to this! Don't make me look down on you!" Sasuke Uchiha roared, his eyes burning with fighting spirit.

In a sense, Sasuke is now a typical "debt king" type of player.

He can fuse and evolve with his bonded partners, and no matter who he is with, he can gain terrifying power that increases exponentially.

Moreover, each has its own unique characteristics, much like the new forms in tokusatsu films. Each fusion brings new surprises and a powerful boost in strength.

Furthermore, Sasuke recently discovered that flesh-blood fusion evolution is not limited to two people; multiple people can fuse together, although the more people involved, the higher the failure rate and the worse the effect.

For example, if A has extremely high compatibility with B and C, but the relationship between B and C may actually be just average, it will be extremely difficult for them to successfully merge. Even if they manage to merge, they will not be able to unleash their full power.

However, Sasuke knew very well that he had successfully combined with Suigetsu and Jugo before, and the powerful force resulting from that fusion was still fresh in his memory.

Therefore, he was not afraid of Naruto at all. At worst, he would call for reinforcements and let Naruto see what the power of true bond fusion was like. That was something that could not be experienced just by talking about it!

At this moment, Sasuke was actually a little annoyed by Naruto's contemptuous expression that seemed to say, "Let's see if you're any good, or we can stop fighting."

He figured that as long as Naruto used more of the Six Paths power first, he could feel more at ease calling for reinforcements.

Moreover, given that this place is located by the ocean, Shuiyue can play a significant role here. It's a perfect combination of favorable timing, location, and human factors.

"Hoo... Sasuke, you're right. My overwhelming power made me a bit arrogant. Facing a genius like you, I really should give it my all."

"Release!" Naruto took a deep breath, his eyes becoming firm and resolute.

He slowly pulled open the mesh underwear, his thumb glowing with chakra, and then precisely pressed it against a specific spot.

In an instant, countless dark patterns appeared on his body, spiraling around as if containing endless mysteries.

Boom—! Terrifying chakra erupted from Naruto's body like a volcanic eruption, and a golden pillar of light shot into the sky, shattering the clouds and instantly brightening the originally gloomy sky.

Terrifying hurricanes swirled around Naruto Uzumaki, emitting sharp howls.

Even this seemingly deep ocean was shaken apart, revealing some dark brown rock layers, as if it had been cleaved open by an invisible giant blade.

"What?! This powerful chakra..." Sasuke's eyes widened in disbelief. He had only intended to taunt Naruto, but he hadn't expected the guy to actually be hiding so much power! Damn it, it seems he can't hold back either!

"Summoning Jutsu!" Sasuke swiftly formed hand seals inside the Susanoo cockpit, his movements fluid and rapid.

With two loud thuds, Suigetsu and Jugo appeared on Sasuke's left and right sides, respectively.

As soon as Shuiyue appeared, she looked around in complete bewilderment.

"Sasuke, what is it now..."

Just as Mizuki was about to say something, she suddenly saw the scene that resembled a natural disaster. She was so frightened that her legs went weak and began to tremble uncontrollably. She instantly hid behind Sasuke, muttering, "Wow! What... what is going on?!"

Water dripped from her body, as if she were melting, and her voice was trembling with sobs, "Lord Orochimaru still has something to ask me, I...I...I...I have to go back now."

"Shut up, Suigetsu! This is an ocean environment, perfect for you to shine. Just sit back and get ready to combine with Jugo and fight."

Sasuke grabbed Suigetsu by the scruff of her neck, his face darkening, his eyes revealing an undeniable air of authority.

"Tch, Sasuke... He's a member of Team 7, yet he's always so domineering."

Meanwhile, Naruto, who was breaking the seal, frowned as he looked at the two people who suddenly appeared in Sasuke's cockpit. He knew they were the Hawk or Snake Squad.

Naruto's eyes gradually turned hostile, and he became secretly on guard.

Boom! Sasuke spread his arms and punched Suigetsu and Jugo, his movements full of power.

Three beams of light—purple, blue, and yellow—soared into the sky. The purple beam was at the center, while the blue and yellow beams intertwined and swirled upwards, eventually merging into a magnificent beam that illuminated the entire battlefield.

The sound and light effects created by Sasuke and his group were even more spectacular than those created by Naruto when he was about to be unsealed.

"Naruto, let me show you what true bonds are."

True bonds are not just sweet words spoken lightly, nor are they superficial gestures.
