The man smiled and said, "Ren... long time no see!"
Ren chuckled. "It really has been a long time."
Ever since Nawaki returned to the ancestral grounds, aside from Tsunade and Orochimaru, no one else had been able to see him.
Although Ren and Nawaki had exchanged letters over the years, this was their first meeting.
Six years had passed, and Nawaki had not changed much, aside from growing quite a bit taller.
Nawaki stared at Ren and said, "We haven't met in six years, and we're fighting the moment we do? Big Sis is really ridiculous!"
He looked at Tsunade with resentment, while Tsunade showed a trace of anger. "Ridiculous or not, Ren is twelve this year, while you're sixteen. If you lose today, I'll let you know how terrifying your big sister can be!"
That teasing gaze made Nawaki shudder. He then looked at Ren and said seriously, "Looks like I can't go easy on you!"
Ren shook his head. "Hehe... We haven't met in six years, but your boasting has gotten much bigger. Do I need you to go easy on me? If I'm not careful, I might have to go easy on you so you don't lose too badly."
As soon as he finished speaking, Nawaki drew a kunai, while Ren had already pulled out the Stellar Katana.
This katana came from the Swallowed Star world, and Ren called it the Stellar Katana.
Nawaki stared at Ren's Stellar Katana, the corner of his mouth twitching. "This is a spar. Why are you using that katana?"
Nawaki clearly remembered just how sharp and terrifying the Stellar Katana was.
Ren looked at Nawaki's kunai. "Fine... I won't bully you."
A katana from Swallowed Star against a kunai from the Naruto World really was bullying. After all, such a kunai was like tofu before Ren's katana—it would break with a single slash.
At that moment, Nawaki's expression grew steady as he charged forward at great speed.
The instant he rushed in, he raised his kunai.
Bang...
Just as he neared Ren and thrust out his kunai, he saw a substitution log appear.
Nawaki was stunned. "Substitution Technique? When did you—"
Before he could finish, the substitution log shattered and turned into Ren. Smiling faintly, Ren grabbed the kunai and placed it against Nawaki's neck. "Nawaki... that was the Transformation Technique, not the Substitution Technique. And we're ninja, not samurai. Charging straight in leaves far too many openings!"
The kunai rested against Nawaki's neck, leaving a faint bloody mark. That proved this was Nawaki's real body, not some clone.
Nawaki stared blankly. "How is that possible?!"
As he spoke, Ren kicked him squarely in the abdomen and said, "Hehe... You lost once. Let's start again. Let me see what Orochimaru has taught you."
Nawaki was sent flying, disbelief filling his eyes.
Orochimaru, who was slowly approaching from afar, also showed a trace of surprise. "That wasn't something a novice would do. Why does Ren feel like such a seasoned fighter?"
Tsunade was equally shocked. "Yes! That really is strange!"
Ren did not know how shocked Tsunade was, but he had long understood that what he lacked was combat experience. He had originally been wondering how to improve it, yet he had never expected the Trash Station to send him a perfect gift.
It was precisely this gift that allowed a combat novice like Ren to accumulate considerable fighting experience. Ren remembered it had been a batch of trash from three years ago. After two years of training, growing older, and long-term consumption of Magical Beast meat and medicinal baths, his physique had finally undergone a qualitative transformation. He broke through his previous limits in one stroke, bringing new trash to the Trash Station.
Since the increase in his physique had not been especially great, there was no trash from high-level worlds such as the Battle Through the Heavens World. However, this batch of trash was exceptionally precious and of immense help to Ren. It came from the world of Qin's Moon, and its source was the Mohist Mechanism City. It seemed that after the Mohist Mechanism City was destroyed, it turned into trash and entered the Trash Station.
More than half of the enormous Mechanism City had actually become trash and entered the Trash Station.
Ren searched through the vast Mechanism City and gained a great deal. His greatest harvest was the Mohist Mechanical Beasts, which became his sparring partners.
He constantly fought the Mechanical Beasts, honing his combat skills among them. The Dog Clan also had all kinds of grown dogs, and they too became Ren's opponents.
Countless sparring sessions had made Ren battle-hardened.
At that moment, Ren narrowed his eyes and stared at Nawaki in the distance.
Nawaki's powerful recovery ability had already healed the wound on his neck, though Ren's kick had been quite heavy.
Nawaki clutched his abdomen in pain. "That hurts! But I actually lost to Ren. If that had been a battlefield, I'd already be dead. Fine, then take a look at the ninjutsu I've painstakingly trained over the past six years!"
As soon as he finished speaking, his hands rapidly formed seals.
Water Release—Water Wave!
In an instant, Nawaki spat out a wave of water that surged directly toward Ren.
Ren stared at Nawaki. "Water Release? Looks like you want to learn from the Second Hokage!"
Ren watched the Water Release before him. The current was powerful, nothing like an ordinary Water Release ninjutsu. Perhaps it was because of the river behind Nawaki, or perhaps because Nawaki possessed the physique of the Senju Clan.
Yet the torrent shot forward at high speed, packed with Chakra and carrying terrifying force.
Ren instantly reacted, his hands already forming seals.
Fire Release—Fireball Jutsu!
The Chakra in his body surged at once, then erupted from Ren's chest.
A fireball three meters in diameter appeared, its scorching heat far beyond that of ordinary flames. Seeing this fire, Orochimaru praised from afar, "Such scorching flames... could Ren's Chakra already be undergoing nature transformation training?"
Tsunade shook her head. "I tested Ren before. His Chakra has two attributes: lightning and fire. But I never taught him Chakra nature transformation."
In contrast to Tsunade and Orochimaru's surprise, Ren merely smiled confidently. He naturally knew about training fire-attribute Chakra, and there were even records of it in his grandfather's scrolls. After all, most members of the Uchiha Clan possessed both lightning and fire Chakra attributes.
Although Ren had wanted to train it, he had never found the key. The reason his Fire Release was now so powerful came entirely from Fire Tiger meat. The Fire Tiger from Perfect World naturally contained powerful fire elements. Having eaten its meat for so long, Ren had unknowingly absorbed some of that scorching aura, making his Fire Release even more blisteringly hot.
Choice
On the training ground, flames collided with rushing water.
Ordinarily, water could easily extinguish fire. Unfortunately, the flames before them were terrifying. Their scorching temperature instantly evaporated the oncoming water and overwhelmed it.
Boom...
The flames and water collided with a thunderous roar. The water was immediately vaporized, and dense steam spread through the surrounding area.
The fireball and water current vanished, while the area became shrouded in steam.
Ren narrowed his eyes and spread out his sensing ability. "Over here?"
The moment he spoke, Ren vanished from where he stood.
In the blink of an eye, Ren's kunai was once again pressed against Nawaki's neck. "Nawaki... that's the second time!"
