The Shinobi World's Greatest Sensor

Hinata Hyuga had the innate qualities needed to become powerful. For Otsutsuki Toneri to take an interest in her, her talent was beyond question.

It was her other traits that kept her from becoming truly strong.

Hinata's timid personality and lack of ambition prevented her from becoming a true powerhouse.

Of course, if someone told Hinata that becoming the strongest in the shinobi world would let her date Naruto Uzumaki, she would probably rise straight to the top. Even if she did not become the strongest, she would at least have been a better fit than Sakura Haruno for that three-person squad.

Some people also said that Hinata Hyuga had failed to become powerful because she did not eat enough and was never full.

That was a pretty good explanation. Uchiha Yi also thought there might be something to it. Nutrition mattered a great deal to ninja.

He was confident he could face Hinata Hyuga from the Fourth Shinobi World War, too.

Of course, the one Uchiha Yi cared about most was Young Tobirama. That old bastard Tobirama Senju had far too many things he wanted: combat talent, sensory abilities, ninjutsu talent, Water Release talent, and all sorts of talents for scheming and plotting.

Although Tobirama Senju lacked Hashirama Senju's power, he was still formidable.

One could say that, in that era, if Hashirama Senju had not appeared with his practically cheat-level powers, Tobirama Senju would have been the best candidate to lead the Senju Clan.

According to the information Uchiha Yi had gathered, Tobirama Senju was more than a match for his father.

Hashirama Senju and Madara Uchiha were simply far too far beyond the norm.

Fortunately, this was only the young Tobirama Senju. Uchiha Yi did not even dare imagine facing him after he had fully matured.

Uchiha Yi glanced at Tsunade beside him, then immersed his mind in the battle space.

White Zetsu was easy to deal with. Uchiha Yi obtained one White Zetsu's worth of chakra. Although he was a little disappointed, that was still a substantial amount.

If the future Kakashi found out, he would probably cry with envy.

Defeating Hinata Hyuga took some effort, but Uchiha Yi still managed to finish her off. The battle space awarded him Gentle Step Twin Lion Fists.

This was a secret, advanced taijutsu taught only to the Main Family, and it incorporated chakra shape transformation.

With Gentle Step Twin Lion Fists and Eight Trigrams Sixty-Four Palms, Uchiha Yi felt that he might seem more like a Hyuga than the Hyuga Clan themselves.

Leaving everything else aside, although Hyuga Rinka had already mastered Eight Trigrams Sixty-Four Palms, she had not mastered Gentle Step Twin Lion Fists. Otherwise, she would have used it long ago.

After all, Hyuga Rinka was only around ten years old.

Getting this far already made her a genius within the Hyuga Clan.

The Ninja Academy in this era did not have the six-year program it had in Naruto's time.

At that thought, Uchiha Yi could not help feeling a little wistful again. No matter how inept Hiruzen Sarutobi had become in his old age, he had indeed protected some children by extending their schooling from four years to six.

Unfortunately, he did not have the Byakugan. Otherwise, Uchiha Yi felt he could impersonate a Hyuga when he went out to cause trouble in the future.

With the Byakugan, Eight Trigrams Sixty-Four Palms, and Gentle Step Twin Lion Fists, no one would believe him even if he said he was not from the Hyuga Clan!

For now, Uchiha Yi could not use these openly.

The young Tobirama Senju did not take too much effort to defeat. Uchiha Yi estimated that this version of him came from around the time Hashirama Senju and Madara Uchiha first broke ties.

At that point, Tobirama Senju was not really even an adolescent yet, only around eight or nine years old. Still, if one insisted on calling an eight- or nine-year-old Tobirama Senju a youth, that worked too.

But his young age did not mean he was weak.

In fact, he already had the strength of a chunin. Combined with that sly bastard's personality, fighting him was genuinely troublesome. His approach was the sort that said, even if you killed him, he would make you pay dearly and leave you wounded so that the other members of the Senju Clan could finish off an evil Uchiha like you.

Fortunately, Uchiha Yi had no fear of getting hurt inside the battle space. As long as he was willing to pay the price, he could kill Tobirama Senju.

Ding! Congratulations to Uchiha Yi for defeating Young Tobirama Senju. You have obtained Tobirama Senju's sensory abilities. Would you like to integrate them?

Integrate! As he silently gave the command, Uchiha Yi could not help growing excited.

Sure enough, Tobirama Senju was a treasure trove. What Uchiha Yi had lacked most when using the Flying Thunder God Technique was sensory ability.

In truth, Uchiha Yi's sensory abilities were already quite good, but they fell short when he tried to use them effectively at high speeds.

That was the main reason he could use the Flying Thunder God Technique, yet could not apply it in combat.

Uchiha Yi was confident that, given time, his sensory abilities would improve even without the battle space's help.

But integrating Tobirama Senju's sensory abilities was a different matter. Only then did Uchiha Yi realize just how terrifying those abilities were.

These were merely Tobirama Senju's sensory abilities in his youth. Later on, he could sense the Ten-Tails' chakra signature all the way from Konoha.

Perhaps some ninja surpassed Tobirama Senju in the precision of their sensing.

But in terms of range, Tobirama Senju might well have been the greatest sensor in the shinobi world.

Now that Uchiha Yi had obtained the young Tobirama Senju's sensory abilities, sensing everything within ten kilometers was no difficulty for him. If he only focused on large chakra signatures, his range could increase to at least three times that distance.

And now, Uchiha Yi was almost certain he could use the Flying Thunder God Technique while moving at high speed.

I'm about to become invincible! Uchiha Yi shouted inwardly.

Of course, he did not think being able to freely use the Flying Thunder God Technique alone made him invincible. Rather, it gave him a genuine means of protecting himself.

With the Flying Thunder God Technique, Uchiha Yi could run away even if he could not win.

Given his current situation, all Uchiha Yi needed was time to grow.

To become a true top-tier powerhouse in the shinobi world.

"What's wrong?" Kushina Uzumaki asked with a hint of curiosity, seemingly noticing Uchiha Yi's change in mood.

"Something I couldn't figure out before suddenly clicked just now. I'm close to mastering a ninjutsu," Uchiha Yi said, brimming with confidence.
