Bullying is bad!

Now, Rasengan was in Kazuya's hands. However, upgrading it posed a challenge. In the current ninja world, very few ninjas knew Rasengan, making it difficult to gain skill experience. Ninjutsu, as a strategic resource, was heavily guarded by all major ninja villages, with high learning thresholds. Even C-level jutsu like Great Fireball were confidential and inaccessible to most common ninjas.

Fortunately, cultivating Rasengan wasn't extremely difficult. Kazuya recalled that Jiraiya had learned it in just three years. Given Kazuya's talent, he expected to master it even faster. His Rasengan level was already nearly at lv3, which was sufficient for the time being.

"Rasengan..." Kazuya mused. The technique had two significant advantages: it required no seals and had no inherent attributes. The lack of seals allowed for quick use, and combined with the Flying Thunder God Technique, its lethality was terrifying. Without attributes, it could accommodate various Nature Transformations, much like the diverse Rasengans of Naruto in the original story. In many ways, Rasengan seemed tailor-made for Kazuya, who had both the Flying Thunder God and all five Nature Transformations—fire, thunder, wind, earth, and water. In terms of configuration alone, he surpassed even Naruto.

"Now..." he thought. "My basic setup is already quite luxurious. Next, the most important thing is the bloodline."

Kazuya had a rough plan for the future. His vision extended far beyond his time. In this world, even the leaders of the major ninja villages couldn't match his foresight, because he alone knew the full plot. The pinnacle of mortal cultivation included figures like the Fourth Hokage, Killer Bee, and Hanzō of the Salamander. However, at the true Six Paths level, or against Ōtsutsuki-level power, the peak of mortal abilities was meaningless.

For instance, the "half-god" Hanzō, who had dominated the ninja world for decades, was ultimately killed by Six Paths Pain. Similarly, the Ninja Alliance was powerless against Six Paths Obito, unable to even make a significant stand.

This ultimate challenge was still far off, and Kazuya had plenty of time to prepare. His short-term goal was to acquire the bloodlines of Asura and Indra's descendants: the Senju and Uchiha clans.

Kazuya had long focused on these two clans. He had monitored the Uchiha clan for some time but had yet to find a suitable opportunity. Kakashi's Sharingan only granted him pupil power, not Indra's bloodline. Moreover, his battle with Orochimaru had been too one-sided to yield significant gains.

As for Uchiha Shisui and other Uchiha members, Kazuya hadn't even encountered them yet. "Uchiha Fugaku," Kazuya sighed, "why are you less confrontational than Danzo? You've awakened the Mangekyō Sharingan, but you still won't challenge the Third Hokage? Disappointing!"

In the following days, Kazuya led a leisurely life, checking in at Anbu daily and training at the grounds to collect chakra. Occasionally, Kurenai would take him shopping, and he'd collect more chakra points. Soon, he amassed over 2,000 chakra points, bringing his total to:

[Chakra: lv4 (92100/100,000)]

With ninety thousand chakra points, Kazuya had reached the peak of Kage-level power. He now felt confident enough to take on Jiraiya head-on, even in Sage Mode. This peak strength meant few opponents in the current ninja world could match him. With the Flying Thunder God, ordinary ninjas posed no threat. He was on the verge of reaching the Super Kage-level, a step away from extraordinary power.

While Kazuya shopped, the Third Hokage sent him some advanced ninjutsu scrolls:

- Level A: Shuriken Shadow Clone Technique

- Fire Style: Great Fire Annihilation

- Lightning Style: Lightning Clone

- Wind Style: Vacuum Waves

These were all powerful jutsu, indicating the Third Hokage's growing satisfaction with Kazuya's recent performance. "Shuriken Shadow Clone Technique," Kazuya thought, "wasn't this originally created by the Third Hokage, a jutsu passed down to his direct disciples? Why give it to me?"

Reflecting on his new mission to train under Tsunade, Kazuya realized, "Sarutobi Hiruzen might be grooming me as a Hokage candidate!" This was surprising, given Kazuya's casual attitude towards such ambitions. Nonetheless, standing taller always had its benefits. Perhaps he wouldn't need Uchiha Obito's intervention to start the Fourth Ninja World War; he could do it himself.

Notably, Uzuki Yugao's admiration for Kazuya had grown since the Orochimaru mission. She looked at him with sparkling eyes, almost idolizing him. "Captain Kazuya, please train me hard!" she often exclaimed, which led Kazuya to call Kurenai.

The three of them went to a remote training ground where Kurenai unleashed all her genjutsu on Yugao during sparring. This included:

- Magic: Binding Kill

- Illusion: Threefold Sakura

- Illusion: Naraku Clone

- Illusion: Falling Sakura

Kurenai, determined to show her best, bombarded Yugao with these illusions. Jōnin versus Chūnin quickly became a one-sided battle.

[You picked up the illusion: Falling Sakura] 

[You picked up the illusion: Naraku Clone] 

[You picked up the illusion: Magic: Binding Kill] 

[You picked up 100 points of illusion talent] 

[You picked up 100 points of illusion talent] 

[You picked up 80 points of illusion talent] 

[Your illusion talent level has increased, currently: lv4 (0/1000)]

Watching the two women spar, Kazuya soon upgraded his illusion talent to lv4. "I can still improve!" he thought, pleased with Kurenai's efforts.

Kurenai, exhausted but smiling, shared Kazuya's satisfaction. Meanwhile, Yugao, after five hours of relentless genjutsu torture, ran off in tears. Her spirit was nearly broken, and her admiration had turned to frustration. "Captain Kazuya! Captain Kurenai! I hate you both!" she thought, feeling utterly defeated.
