Naruto and Boruto

"Huh?" Shiyu naturally saw the two children: Boruto, who was dressed a little more elegantly, and Naruto, who was wearing his signature outfit.

"You two want to learn Ninjutsu from me?" Shiyu asked.

"Yes!" Naruto and Boruto affirmed.

"Why don't you learn from that older brother?" Shiyu asked, puzzled. Although Sasuke's strength was far inferior to hers, he was still a rare master in the Shinobi World.

The two shook their heads in perfect unison.

"I think you're stronger than that guy, big brother!" Naruto said directly.

"He also told me to learn more from you recently," Boruto said.

Only Shiyu roughly understand that Sasuke, being so intelligent, naturally knew that Boruto would definitely make greater progress after learning a few moves from Shiyu.

As for Naruto, he didn't know Sasuke's identity, but just by looking at him, he could clearly sense that Shiyu was stronger than the other person, so he directly chose to go with Boruto to learn Ninjutsu from Shiyu.

Shiyu and said, "If you want to learn Ninjutsu from me, that's fine. Do you two both know the Rasengan?"

"Rasengan, no problem at all." After saying that, Naruto used the Shadow Clone Jutsu, and then had his Shadow Clone help him create a blue Rasengan in his hand.

"I can too." Boruto was much smarter. He didn't need Shadow Clone; he directly created Rasengan with his hand. Although this Rasengan seemed less powerful than Naruto's, it incorporated spatial attributes. In other words, it was a Rasengan that could disappear.

Shiyu nodded and said, "Alright, now that you've all learned the Rasengan, unleash it on me."

"What!?" Senior!?

Are you serious?

Both of them were quite surprised. They'd only just begun asking for advice, and now he was already going to bombard them with his most prized Ninjutsu?

Shiyu laughed and said, "Don't think too much about it. Don't think you can hurt me with your strength. Just bombard me with your Rasengan. You want to learn Ninjutsu? At least let me see how strong your Rasengan are, right?"

At Shiyu's urging, Naruto and Boruto exchanged a glance, then attacked Shiyu from the left and right respectively.

"Watch out, teacher!" Boruto kindly warned.

Shiyu has already reached such a level that he naturally feels no pressure whatsoever when facing Boruto and Naruto's Rasengan.

"Rasengan!" the two shouted, then slammed their Shiyu.

"Bang!" Shiyu's actions were simple: he grabbed the two men's wrists and pulled their hands to the ground.

Immediately afterwards, the ground was blasted open with a loud "boom," creating two large craters.

"What's going on?" Boruto and Naruto were both very surprised. They didn't expect Shiyu to be so fast. Their attacks were about to touch Shiyu, but Shiyu easily neutralized their attacks at the last moment.

Naruto was also somewhat bewildered.

"What exactly happened?"

Shiyu then began to explain the mode, "Your Rasengan is powerful enough, but no matter how powerful it is, it is still a striking Ninjutsu. The Rasengan is a hand seal-less Ninjutsu, so it should be cast instantly. When attacking, you should hit the target you want to attack as quickly as possible."

"Watch me." Shiyu then summoned a Rock Clone, and the two exchanged blows for several rounds. Then Shiyu struck out with a palm strike, and at the same moment, a Rasengan suddenly condensed in his palm.

The Rasengan, formed in an instant, defeated his own Rock Clone with a single strike.

"That's amazing!"

"That's a fast Rasengan?!"

"How exactly did they do that?"

Naruto and Boruto both found it very difficult to understand.

Shiyu then grabbed both of their hands and said, "What I just demonstrated was an instant Rasengan. When engaging in close combat with an enemy, unless the enemy exposes a huge opening, Naruto would miss the best opportunity if he summoned a Rasengan Shadow Clone then used his hand to create a Rasengan."

"Boruto, your problem is equally obvious; the production time for the Rasengan is simply too long," Shiyu said.

"But if you don't give it enough time, the Rasengan won't be able to condense and take shape, and then it will lose its attack power," Boruto cleverly retorted immediately.

"That's your problem. I can make Rasengan instantly." Shiyu spoke, he immediately opened his palm, Rasengan formed directly in his hand. He even demonstrated the ability to create a super mini Rasengan with his fingertips.

"Amazing! I've never seen anyone use the Rasengan so perfectly!"

"Wait a minute, didn't the Rasengan Pervy Sage say that only he and the Fourth Hokage?" Naruto asked.

"You can do it too, can't you? Boruto can too, and even Kakashi can. It's just that the Lightning Blade might suit him better. It's not a particularly difficult move to begin with." After Shiyu taught the two, they understood their weaknesses.

"Different battles require different fighting methods. If you're facing an enemy who uses ranged attacks, it will be very difficult for you to defeat them, Naruto. Do you understand?" Shiyu asked.

Naruto then nodded as if he didn't quite understand, but it was clear that Boruto had already figured it out.

Shiyu couldn't help but think to herself, "Boruto is definitely smarter."

Shiyu then added, "Your chakra natures are very similar, so you can try the strongest Rasengan! Taiji Rasengan!"

"Taiji Rasengan!?" Boruto and Naruto were both very excited, having never heard of this Rasengan before. They immediately asked, "Excuse me, what is the Taiji Rasengan?"

"First, you need to adapt to each other's chakra, then achieve a fusion of chakra. After that, you can unleash the Rasengan together, which will create the most powerful Rasengan. However, this technique is quite difficult. Although your chakra natures are very similar, it is indeed quite challenging. If you don't believe me, you can try it."

Shiyu finished speaking, Naruto and Boruto began their experiment, but they quickly failed. They tried many more times afterward, but all their attempts ended in failure.

"This is not something that can be accomplished overnight. Only a genius like the Fourth Hokage, Minato Namikaze, could instantly merge with Naruto's chakra and use the Taiji Rasengan to defeat the enemy!" Shiyu thought.

But then again, in terms of talent alone, Boruto and Naruto are actually no Minato.

"I have faith in you two. Don't rush. Take your time cultivating. After all, there's still some time before Urashiki's invasion." Shiyu then sent the two a space, while he secretly observed from the side.
