Night fell.
Uzuki Yugao arrived in the Land of Waves.
Su Yu introduced her to Karin Uzumaki.
Karin felt somewhat nervous in Uzuki Yugao's presence.
The nine shinobi trainees were even more tense.
After the brief meeting ended,
Karin went back to practicing Sealing Jutsu, while the nine shinobi trainees returned to their lodgings.
Su Yu and Uzuki Yugao sat across from each other at the low table.
She had already given Tsunade's necklace to Su Yu, but now she didn't know what to say.
Tsunade had sent her to stay by Su Yu's side more to keep an eye on him than to protect him.
Given Su Yu's strength, he should be protecting Uzuki Yugao, not the other way around.
"Lady Tsunade isn't hopeful about me. She's afraid of the Kekkei Genkai I possess. She sent you here not to keep an eye on me, but because she doesn't trust you." Su Yu spoke.
"I... I know." Uzuki Yugao lowered her head.
On the way here, she had thought about it a lot and understood Tsunade's intentions.
"I mean no harm to Konoha. The only person I want to deal with is Danzo, so you don't need to worry about me coming into conflict with the Hokage's faction." As he spoke, Su Yu held Uzuki Yugao's small hand.
"Su Yu, I..."
"I haven't fulfilled our promise yet. Once I've helped you get your revenge, you'll stay by my side forever and follow me for the rest of your life, all right?" Su Yu tightened his grip on her hand.
"I... I promise." Uzuki Yugao spoke softly.
Hearing her answer, Su Yu gently kissed the back of her hand and stood up.
"It's getting late. Good night."
"Good night." Uzuki Yugao watched Su Yu.
Su Yu left the room.
She watched his back until he disappeared from view.
Su Yu returned to his room and shut the door.
He took out a scroll. It held Shukaku's severed arm, and the Tailed Beast Chakra inside had yet to dissipate.
Su Yu opened the scroll. Several golden chains emerged from his back, wrapped directly around Shukaku's arm, and began absorbing the Tailed Beast Chakra.
The mass of Tailed Beast Chakra slowly grew larger. It wasn't as violent as he'd imagined; instead, it was quite gentle.
That was probably because it had no consciousness.
Once all the Tailed Beast Chakra had been drawn out, Shukaku's arm crumbled into a pile of sand.
Su Yu had completed his Adamantine Sealing Chains.
The mass of Tailed Beast Chakra was now sealed away. When he needed to use it, he only had to draw out a little to increase the power of his ninjutsu.
But would the Tailed Beast Chakra eventually be used up?
In fact, the Adamantine Sealing Chains had only extracted a trace of the Tailed Beast Chakra. As long as the Tailed Beast Chakra sealed inside remained, it could continue to gather more.
In other words, it wouldn't diminish; it would keep growing.
Although he couldn't use Shukaku's chakra to cultivate a complete Shukaku, given enough time, Su Yu could still gain some of Shukaku's abilities.
For example, controlling sand.
That was one of the benefits of Tailed Beast Chakra.
Once I've mastered the Rasenshuriken, I can go collect the chakra of the other two Tailed Beasts...
Su Yu thought to himself.
For now, those were the only two Tailed Beasts whose chakra he could get his hands on.
The next day.
Su Yu began training in the Rasenshuriken.
It was an S-rank ninjutsu, so naturally it wasn't easy to master.
Fortunately, Su Yu still remembered how the Rasenshuriken worked. It took him only half a day to find the right approach.
At lunchtime,
Uzuki Yugao brought him lunch.
As Su Yu ate, he continued thinking about the Rasenshuriken.
Uzuki Yugao knew that when Su Yu got serious about training, he became completely absorbed in it, so she didn't disturb him much.
After finishing lunch,
he continued training until sunset.
His hands were trembling slightly.
Only then did he realize something.
To master this ninjutsu, he had to control the Rasenshuriken without letting it injure him.
But an S-rank ninjutsu required far more chakra than a Rasengan. It wasn't easy to control at all.
If he lost control, he could suffer anything from an injured arm to a completely ruined one.
In the original story, Naruto Uzumaki only managed to throw the Rasenshuriken after learning Sage Mode.
The problem Su Yu was facing now was that he couldn't throw it.
If he couldn't throw it, it was just an incomplete S-rank ninjutsu. Using it would hurt both his enemy and himself.
At dinnertime,
Su Yu sat at the low table, thinking about how to solve the problem.
Uzuki Yugao brought dinner over and sat across from him.
Su Yu looked at the meal in front of him and picked up his chopsticks. Just as he was about to eat, he froze.
Then his face lit up.
"Yugao, thank you."
Uzuki Yugao was taken aback, not knowing why Su Yu was thanking her.
After thanking her, Su Yu quickly ate his meal.
A few minutes later,
he disappeared with the Body Flicker Technique.
Could Su Yu have made a breakthrough in the ninjutsu he's been training? Uzuki Yugao wondered.
On the beach,
Su Yu began gathering the Rasenshuriken again.
This time, he added Shukaku's chakra.
Wrapped in Shukaku's chakra, the small Rasenshuriken slowly took shape and grew more stable.
At last, a palm-sized Rasenshuriken appeared in Su Yu's hand.
He looked at it, a faint smile appearing on his face.
As expected, his idea had worked.
If he formed the Rasenshuriken directly, the chakra inside was too violent. But after adding Shukaku's chakra, it became much more stable.
The moment he picked up the chopsticks, he'd realized that the Rasenshuriken was a lot like a steaming hot meal: neither could be touched directly with bare hands.
Chopsticks were a tool that let him handle something too hot without touching it directly—and Shukaku's chakra worked just the same way.
Compared to his own chakra, Shukaku's was gentler.
Of course, this was still only a prototype.
A Rasenshuriken this small had the power of an A-rank ninjutsu at most. To complete it, he had to mix the chakra in the right proportions.
Su Yu threw the small Rasenshuriken.
The sea rippled.
He looked with his Byakugan.
The fish around the spot where the Rasenshuriken struck were scraped by tiny strands of wind-nature chakra, and a whirlpool rose up.
Wind- and water-nature chakra should be able to combine into ice-nature chakra. If I could study how to create an ice Kekkei Genkai by combining the two kinds of chakra...
Su Yu thought to himself.
It wasn't impossible. The shinobi of the Snow Hidden Village could use ice-style ninjutsu. Although they relied on the local environment, it still showed that ice-style ninjutsu wasn't 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 whole string of things in his mind.
