Some things really shouldn't be said too confidently.
A moment ago, Roshi was still reassuring the Four-tailed Son Goku, and the next moment, he was almost overwhelmed by a series of Taijutsu exchanges.
It was practically a live stream of getting slapped in the face.
Bang!
The young ninja punched Roshi in the chest, sending him flying, and then slowly shook his wrist: "Hey, when you get older, you should just enjoy retirement, understand?"
"Bastard!"
Roshi wiped the blood from the corner of his mouth, suddenly clasped his hands together, and a surge of scorching heat emanated from his body: "Lava Release Chakra Mode!"
This was his signature Nin-Taijutsu.
The Lava Release Chakra Mode turned Chakra into lava enveloping his body, enhancing Roshi's defense, making it strong enough to ignore some Ninjutsu attacks.
Moreover, the searing lava on Roshi's body surface would burn the attacker's skin, preventing Roshi from falling into a disadvantage during Taijutsu combat.
When the Lava Release Chakra Mode was complete, Roshi had transformed into a lava man billowing with heat, and he lunged towards the young ninja: "Brats should stay home well-behaved instead of causing trouble outside!"
"Tsk... how terrifying!"
The young ninja extended his palm, and a Void Blade appeared in his hand, slashing towards Roshi!
Against such an enemy with Chakra dense enough to envelop themselves in a Chakra mode, the Void Blade was the best choice.
The Void Blade could absorb the opponent's Chakra for the user's benefit, akin to the Shark Skin Greatsword in Hoshigaki Kisame's hands.
Compared to the Shark Skin Greatsword, the Void Blade was much more obedient.
Whether it's lava or anything else, the Void Blade simply keeps cutting!
Swish!
The young ninja crouched to dodge Roshi's attack, and the Void Blade in his hand cut open a gash on his lava body, instantly feeling a surge of Chakra entering his body!
"This is..."
Roshi's expression changed dramatically!
The next moment, the young ninja's Void Blade continued to land on him, and in a short while, the once indestructible lava body was slashed with seven or eight gashes!
What shocked Roshi even more was that under the attack of that strange ninja blade, his Chakra rapidly dwindled, so much so that he couldn't even maintain the Lava Release Chakra Mode...
"Seems like I was right."
The young ninja slowly raised the Void Blade in hand, a smile appearing at the corner of his mouth: "In the future, I don't have to worry about enemies with too much Chakra..."
The only pity was that the Void Blade absorbed the Jinchuriki host's Chakra, not the Tailed Beast's Chakra.
Weakly covering his wounds, Roshi gradually recovered with the Chakra bestowed by the Four-tailed Son Goku, and a tail appeared behind him!
This was the state of borrowing Tailed Beast Chakra.
Similarly, this tail was equivalent to Roshi's body, and he could also use this tail for combat!
However, Roshi's face did not ease in the slightest; instead, he anxiously watched the ninja blade in the young ninja's hand, knowing that blade could absorb his Chakra!
That blade was a severe restraint on Jinchuriki!
The young ninja, seeing the tail growing from Roshi's back, showed a trace of fear on his face: "Mo... monster... You're not human!"
Roshi's face turned ugly immediately, recalling his experiences in the Hidden Rock Village, slowly clenching his fist.
"I am not a monster."
Roshi looked at the young ninja, speaking deliberately and solemnly: "Kid, I am not a monster!"
"..."
The young ninja didn't respond.
The next second, the young ninja suddenly vanished from Roshi's sight!
A figure appeared behind Roshi, and at the same time, a sharp blade pierced through Roshi's abdomen!
The young ninja pushed Roshi's body, knocking him to the ground, and slowly pulled the Void Blade out of Roshi's abdomen.
Watching Roshi's tail sway, the young ninja sighed: "Ah, you finally revealed it, huh?"
In the next moment, the young ninja suddenly swung the ninja blade in his hand, directly severing the tail behind Roshi!
"Who the hell are you!"
Roshi punched the ground fiercely, the red Chakra gradually spreading over his body, intending to enter the Half-Tailed Beast Transformation.
However, the young ninja remained expressionless, swinging the Void Blade in his hand, absorbing most of the Chakra from Roshi's body with a few consecutive strikes.
The ninja blade that could absorb Chakra made it impossible for Roshi to enter the Half-Tailed Beast Transformation state, and even the injuries on his body couldn't be healed with the Chakra of the Four-tailed!
"My ninjutsu experiment is complete."
The young ninja squatted down, leaning on the sharp blade in his hand, looking at the weakened Roshi, his face becoming gentle, as if he were a different person!
"Allow me to introduce myself."
The young ninja narrowed his eyes, smiling as he looked at Roshi's face, "My name is Uehara Naraku, a ninja dedicated to the peace of the Ninja World. This is our first meeting, so please guide me in the future, Four-tailed Jinchuriki."
"Bastard!"
Roshi moved his jaw inch by inch, glaring fiercely at the young ninja, "You little brat, you knew I was the Jinchuriki all along, so you deliberately lowered my guard?"
"I was just conducting a ninjutsu experiment and found it amusing as well."
Uehara Naraku shook his head, his expression calm as he explained, "Now it seems my ninjutsu experiment was very successful. Let me remind you, even if I expose my purpose directly, you cannot defeat me."
After finishing, Uehara Naraku glanced at the ground beside him and spoke softly, "Zetsu-senpai, can we count the capture of the Four-tailed Jinchuriki as successful now?"
"Hehehe... Of course."
A Venus Flytrap emerged from the ground, revealing Zetsu's yin-yang face.
Black Zetsu glanced at Uehara Naraku, then at Roshi, and spoke with a sinister smile, "According to our intelligence, Four-tailed Jinchuriki Roshi cannot enter complete Tailed Beast Transformation... Now that he cannot continue to use the Four-tailed's Chakra, we should consider it a success."
"..."
Roshi clenched his fists, assessing the two present, and suddenly grinned, "Ha, finally showing your weakness! Then your information is outdated!"
In the next instant, the Chakra on Roshi's body expanded rapidly!
In almost no time, his body transformed into a gigantic red monkey, with the dense Chakra on it revealing its identity!
Four-tailed, Sun Goku.
No one expected that in the years Roshi was away from the Hidden Rock Village, he had reached an understanding with the Four-tailed through spiritual communication. Although they could not claim one hundred percent trust, they were friends who could rely on each other in times of crisis!
Roshi clearly placed more trust in the Four-tailed Sun Goku, so he readily relinquished control of his body to it, releasing the full form of the Tailed Beast!
"He can actually transform into the Four-tailed directly!"
Black Zetsu's voice was rather displeased, speaking in a deep tone, "Uehara, with this, things will get quite noisy..."
White Zetsu nodded, continuing to add, "If that's the case, it will be easy for the ninjas of the Hidden Rock Village to discover the disappearance of the Four-tailed Jinchuriki, which will be troublesome for our future plan to collect the Five-tailed."
"I didn't expect he could transform into the full form."
Uehara Naraku raised an eyebrow, glanced at Zetsu next to him, and spoke in a low voice, "Zetsu-senpai, no need to worry, it's just a Tailed Beast. I will find a way to handle it, but you should move further away first!"
"Alright."
Zetsu nodded and slowly burrowed into the ground.
Soon after, Zetsu's figure vanished from the spot.
As an intelligence officer, it didn't want to get caught up in the intense battle.
Uehara Naraku raised his head, looking up at the enormous Four-tailed, curling his lips into a smile, "My summoning Sun Goku was replaced with Chakra... I hope after defeating you this time, I can get a new Sun Goku!"
"Brat, then you've drawn the short straw!"
The Four-tailed Sun Goku looked down at Uehara Naraku, swinging its huge fist fiercely, smashing it down where Uehara Naraku was!
Uehara Naraku disappeared from where he was in an instant, and the next moment, he appeared at a distance from Sun Goku, clapping his hands together: "No, you're the one with the bad luck! Water Release: Roaring Wave!"
A wave emerged from under Uehara Naraku's feet, pushing him higher and higher, instantly reaching a height towering over the surrounding peaks, over a thousand meters high...
Moments later, the gigantic wave surged forward, instantly submerging the Four-tailed Sun Goku's body, a crest of the wave flipping it over and drowning it in the sea!
"Is this really a Tailed Beast?"
Uehara Naraku watched the Four-tailed Sun Goku float and sink amidst the waves, continually being overturned by the crests, frowning: "This is quite amusing!"
