Wind Style: Rasenshuriken

As night fell.

Uzuki Yugao arrived in the Land of Waves.

Su Yu introduced Karin Uzumaki to her.

Karin Uzumaki felt somewhat reserved when facing Uzuki Yugao.

The nine ninja students were even more nervous.

After a brief meeting concluded.

Karin Uzumaki went back to practicing Sealing Jutsu, while the nine ninja students returned to their quarters.

Su Yu and Uzuki Yugao sat before a low table.

She had already given Tsunade's necklace to Su Yu, but now she did not know what to say.

Tsunade had sent her to Su Yu's side with the intention of monitoring him far outweighing the intention of protecting him.

Given Su Yu's strength, it should be him protecting Uzuki Yugao, not the other way around.

"Lady Tsunade doesn't have expectations for me, but rather fear of the Kekkei Genkai I possess. Sending you here wasn't to monitor me, but a sign of her distrust in you," Su Yu stated.

"I... I know," Uzuki Yugao said, lowering her head.

On the journey here, she had thought a great deal and understood Tsunade's intentions.

"I hold no malice toward Konoha. The only person I wish to deal with is Danzo, so you don't need to worry about me coming into conflict with the Hokage's faction," Su Yu said, taking hold of Uzuki Yugao's small hand.

"Su Yu-kun, I..."

"I haven't fulfilled our agreement yet. Once I help you take your revenge, stay by my side forever—follow me for the rest of your life, will you?" Su Yu squeezed her hand tightly.

"I... I promise you," Uzuki Yugao whispered.

Hearing her answer, Su Yu kissed the back of her hand lightly and stood up.

"It's getting late. Goodnight."

"Goodnight," Uzuki Yugao watched Su Yu.

Su Yu left the room.

She watched his retreating figure until he vanished from sight.

Su Yu returned to his room and closed the door.

He took out a scroll; this was the scroll containing the arm of the One-Tail Shukaku, and the Tailed Beast chakra inside had not yet dissipated.

Su Yu opened the scroll, and several golden chains emerged from his back, wrapping directly around the arm of the One-Tail Shukaku to begin absorbing the Tailed Beast chakra.

The mass of Tailed Beast chakra slowly grew larger, and it was not as violent as one might imagine; on the contrary, it was quite gentle.

This was likely because it lacked consciousness.

Once all the Tailed Beast chakra had been extracted, Shukaku's arm crumbled into a pile of loose sand.

Su Yu's Adamantine Sealing Chains were complete.

This mass of Tailed Beast chakra was now sealed; when needed, he only had to draw out a small portion to increase the power of his ninjutsu.

As for whether the Tailed Beast chakra would be exhausted?

In fact, the Tailed Beast chakra extracted by the Adamantine Sealing Chains was merely a catalyst. As long as the Tailed Beast chakra remained sealed within, it could continuously condense more of the beast's chakra.

In other words, not only would it not decrease, but it would also constantly increase.

Although it was impossible to cultivate a complete One-Tail using its chakra, as long as enough time passed, Su Yu would be able to possess a portion of the One-Tail Shukaku's abilities.

For instance, controlling wind and sand.

This was the benefit brought by Tailed Beast chakra.

Once I master the Wind Style: Rasenshuriken, I can go and collect the chakra of two more Tailed Beasts...

Su Yu thought to himself.

For the moment, those were the only two Tailed Beast chakras he could access.

The next day.

Su Yu began practicing the Wind Style: Rasenshuriken.

This was an S-rank ninjutsu, so naturally, it was not simple to master.

However, fortunately, Su Yu still remembered the principles of the Wind Style: Rasenshuriken, and it only took him half a day to find the right direction.

At lunchtime.

Uzuki Yugao brought him his meal.

Su Yu ate his lunch while still pondering matters regarding the Wind Style: Rasenshuriken.

Uzuki Yugao knew that when Su Yu worked hard, he became extremely focused, so she did not disturb him too much.

After Su Yu finished his lunch.

He continued to practice until the sun set.

His hands were trembling slightly.

It was only at this moment that he realized one thing.

To master this ninjutsu, one must be able to control the Wind Style: Rasenshuriken without harming oneself.

However, as an S-rank ninjutsu, the amount of chakra required far exceeds that of a Rasengan, making it far from easy to control.

Once control is lost, the best-case scenario is an injured arm, while the worst-case scenario is the total loss of the limb.

In the original story, Naruto Uzumaki was only able to throw the Wind Style: Rasenshuriken after mastering Sage Mode.

The problem Su Yu currently faced was that he had no way to throw it.

If it could not be thrown, it remained nothing more than a semi-finished S-rank ninjutsu; using it once would injure the enemy, but it would injure him just as surely.

Dinner time.

Su Yu sat before a low table, contemplating a solution.

Uzuki Yugao brought over dinner and sat in the seat opposite Su Yu.

Su Yu looked at the meal before him, picked up his chopsticks, and just as he was about to eat, he froze.

A moment later, a look of joy appeared on his face.

"Yugao, thank you."

Uzuki Yugao was stunned, not knowing why Su Yu was thanking her.

After expressing his thanks, Su Yu ate his meal quickly.

A few minutes later.

With a Body Flicker Technique, he vanished from sight.

Could it be that Su Yu-kun has had a breakthrough in the ninjutsu he is practicing? Uzuki Yugao wondered, considering a possibility.

On the beach.

Su Yu began to condense the Wind Style: Rasenshuriken once more.

This time, he incorporated the chakra of the One-Tail.

The miniature Wind Style: Rasenshuriken was enveloped by the One-Tail's chakra, slowly taking shape and becoming increasingly stable.

Finally, a palm-sized Wind Style: Rasenshuriken appeared in Su Yu's hand.

He looked at the Wind Style: Rasenshuriken, a smile spreading across his face.

As expected, his idea was feasible.

If he condensed the Wind Style: Rasenshuriken directly, the chakra within would be too volatile, but after adding the One-Tail's chakra, the internal energy became remarkably stable.

The moment he had picked up his chopsticks, he had associated the Wind Style: Rasenshuriken with the steaming hot food—neither could be touched directly by hand.

The chopsticks acted as a tool, allowing him to avoid touching something too hot, which was exactly the same principle as using the One-Tail's chakra.

Compared to his own chakra, the One-Tail's chakra was far more tempered.

Of course, this was still just a semi-finished product.

Such a small Wind Style: Rasenshuriken had the power of an A-rank ninjutsu at most; to complete it, he would have to experiment with the ratio of the mixed chakra.

Su Yu threw the miniature Wind Style: Rasenshuriken.

Instantly, ripples appeared on the surface of the sea.

He activated his Byakugan to observe.

At the point where the Wind Style: Rasenshuriken struck, the surrounding fish were shredded by the fine wind-natured chakra, creating a vortex.

Wind-natured and water-natured chakra should be able to fuse into ice-natured chakra. If I could research an ice-based Kekkei Genkai through the fusion of two types of chakra...

Su Yu thought to himself.

This was not impossible; the ninjas of the Snow Hidden Village could use ice-based ninjutsu. Although they relied on the local environment, it proved that ice-based ninjutsu was not something only Yuki Haku could use.

S-rank ninjutsu, the chakra of three Tailed Beasts, Tsunade's Medical Ninjutsu and Chakra Enhanced Strength, research into Kekkei Genkai, research into Impure World Reincarnation, the Flying Thunder God technique...

Su Yu listed a mountain of tasks in his mind.
