Buzzzzz!
Lin Yu raised a chakra energy construct, transparent and shaped like a giant shuriken, in his hand. This was no Rasenshuriken with only 50% completion that Naruto had used against Kakuzu, which couldn't be thrown from a distance and would damage one's own arm meridians and bones.
With the augmentation of the advanced Sage Body, Lin Yu could unleash a Rasenshuriken with 100% power without entering Sage Mode, and it wouldn't cause him any self-inflicted damage.
Kakashi stared intently at the transparent, windmill-like ninjutsu in Lin Yu's hand. The piercing sound generated by its high-speed rotation made him instinctively cover his ears.
The powerful airflow, caused by the intense friction with the air, forced Kakashi to retreat. "Damn it! The mere airflow from a ninjutsu is pushing me back! What level of ninjutsu is this?"
Rank A? Or Rank S?
Kakashi felt a pang of fear. If this attack hit him, he would surely die. "Teacher Lin Yu is terrifyingly powerful! Is he really just a teacher at the Ninja Academy?"
Lin Yu steadied the Rasenshuriken in his hand. This was a reward he had just received, and he was still a little unaccustomed to it. Compared to the other forms of Rasengan he had researched over the past four years, he was quite unfamiliar with this one, though its power was undeniable.
Lin Yu lifted the Rasenshuriken and gave it a slight toss. The weight was manageable, and he could still increase the chakra amount.
Kakashi watched Lin Yu's reckless act with a bead of sweat trickling down his forehead. He was terrified that Lin Yu might accidentally hit himself, becoming the first ninja to "kill himself."
Lin Yu looked down at the messy trees around him. "I'll trim these for you. They're too unsightly!"
Buzz! Whoosh!
"He… he threw it!" Kakashi was astounded for the umpteenth time today – possibly more than in his entire life – that Lin Yu could casually throw such high-quality chakra.
"Whoosh!"
The high-speed rotating Rasenshuriken whizzed towards the patch of forest Lin Yu had created earlier, accompanied by a piercing hum. This was perhaps what one would call self-production and self-consumption.
BOOM!
A violent explosion erupted, and a gust of wind swept through. Kakashi felt his collar tighten behind him, and he was lifted into the air. When he came to his senses again, he was already thousands of kilometers away.
Kakashi struggled to get down from Lin Yu's grasp. The fierce wind fluttered the hem of his clothes. Even from thousands of meters away, he could still feel such intense fluctuations. He couldn't imagine what it would be like at the epicenter!
As if sensing Kakashi's thoughts, Lin Yu grabbed him by the collar again. After Kakashi's hairstyle had changed several times, they appeared beside a massive crater!
Kakashi stared blankly at the hundreds of meters wide, circular crater before him, no longer caring that he was still being held by the collar. He murmured, "How can such a powerful ninjutsu exist? It's unbelievable!"
"Is this all that surprises you? You must understand that the ninja world is vast. There are many ninjas who can perform ninjutsu of this caliber!" Lin Yu released Kakashi and dusted off his clothes.
Kakashi gazed at the circular crater for a long time, his eyes growing more determined. He clenched his fists and said, "That's why I must graduate sooner! Only then can I learn ninjutsu of this level as quickly as possible!"
"Huh?"
Lin Yu was baffled. The plot wasn't unfolding as he expected! Lin Yu had envisioned something like this:
Kakashi: "Wow! Senior Lin Yu, you're amazing! Can you take me as your disciple and teach me such advanced ninjutsu?"
Lin Yu: "Ahem! I see you have a noble countenance. In the future, you will surely have a destined encounter with a young man wearing orange goggles. If you can calmly accept this fate, I might make an exception and teach you~"
Kakashi: "Please, great master, accept my deepest respect!"
*Snap.* The fantasy shattered.
Lin Yu scratched his head, perplexed. Kakashi's tsundere nature was proving difficult to change. Making him beg for help was harder than killing him.
Just as Lin Yu was about to speak, his brow furrowed. His Kagura Shingan detected several unfamiliar chakra signatures. It seemed the fluctuations from the Wind Style: Rasenshuriken had attracted some ninja.
Lin Yu sensed them slightly. The chakra fluctuations didn't feel like those of a Konoha ninja. This scent… it felt a bit like… Cloud Ninja?
...
"Taro, are you sure the chakra fluctuation you sensed was in this direction?"
"Absolutely, Boss Yokoyama. Just now, I detected a massive chakra fluctuation that has since disappeared. There's no mistake!" Nohara Taro wiped the sweat from his brow as he spoke to the gray-haired man leading them.
"Boss Yokoyama, could this be a trap? We're just a reconnaissance team, there's no need to go so deep." Nohara Taro felt a shiver of unease. Without personally sensing that chakra fluctuation, no one would believe it. It was comparable to their village's Jinchuriki!
But his captain, Yokoyama Oomanki, insisted on investigating, believing it was a special experiment by Konoha. If they could uncover any secrets, the credit would be immense!
"What are you afraid of? Konoha's main forces are tied up on the battlefield. Besides Hiruzen Sarutobi guarding the main camp, what other powerful ninjas are there? As long as we don't go into Konoha, there won't be any major problems!"
Yokoyama Oomanki was unconcerned. The secret alliance they from the Hidden Cloud had brokered to have the four great ninja villages attack Konoha was no child's play. How could Konoha withstand the pressure from four great villages? Annihilation was only a matter of time.
Nohara Taro fell silent. Yokoyama Oomanki was right. If Konoha possessed such formidable power, they would have long since deployed it to counter the Hidden Cloud ninjas, not allow "leaked fish" like them to infiltrate Konoha's territory.
However, Nohara Taro still had a bad feeling. He was sensitive to chakra perception. The chakra he sensed earlier was not only immense, but also… sharp. Even from such a distance, it made his whole body tremble.
Alas, I hope it's just my imagination. Nohara Taro picked up his pace to keep up with Yokoyama Oomanki, who was charging ahead.
After a while, Nohara Taro's expression shifted slightly. He stopped Yokoyama Oomanki, who was running ahead, and said, "Boss Yokoyama, I'm sensing two chakra fluctuations to the left and front. It seems to be our target. Should we…?"
"Hmm? Observe first, no need to engage. Our objective is to steal intelligence," Yokoyama Oomanki stated.
Nohara Taro nodded silently, slowly descending to the ground and creeping cautiously in the direction he sensed. He hoped neither of the two individuals was a sensory ninja!
In front of the circular crater, Kakashi's expression had calmed down. Lin Yu was much older than him. He believed that if he, Kakashi, were as old as Lin Yu, he would undoubtedly be a Jonin of Konoha!
Lin Yu glanced to his right, reached out, and patted Kakashi's head. He asked him, "Have you ever seen Susanoo ride a wooden dragon?"
