Growth in Strength

At last, near dawn, Naruto successfully mastered the Flying Thunder God Technique.

"Yip. I did it! I did it!"

He stood in the center of the training ground, closed his eyes, and carefully sensed the changes in space.

He used Chakra to draw a complex symbol in the air, one that represented the spatial passage of the Flying Thunder God Technique.

He activated the symbol with Chakra, causing the spatial passage to take effect and alter the surrounding space.

In an instant, Naruto felt something wondrous. He sensed the changes in space, the flow of space, and the leaps through space.

He felt himself merge with space, felt his connection to it.

He experienced an unprecedented sense of freedom and power, and it filled him with excitement.

Naruto opened his eyes and found himself standing on the other side of the training ground.

He had successfully used the Flying Thunder God Technique to teleport from the center of the training ground to its other side.

Looking at where he stood, he knew that he had successfully cultivated the Flying Thunder God Technique and had completely mastered this powerful Space-Time Ninjutsu.

Standing on the other side of the training ground, Naruto recalled that instant teleportation.

He sensed the changes in space, the flow of space, and the leaps through space.

He felt himself merge with space, felt his connection to it.

He experienced an unprecedented sense of freedom and power.

Naruto knew that his training in the Flying Thunder God Technique was not over. He still needed to keep practicing and improving.

What he had cultivated was not the conventional Flying Thunder God Technique. As Naruto, who possessed Top-tier Space-Time Ninjutsu Cultivation Talent, and stood upon the shoulders of giants—

The ordinary Flying Thunder God Technique could no longer satisfy him.

The ordinary Flying Thunder God Technique used formulas to achieve instant teleportation. The user would first leave a Flying Thunder God formula on a target, allowing themselves or objects indirectly in contact with their Chakra to teleport instantly. Once marked, the formula could not be erased.

When well-rested, the user could repeatedly transfer enormous targets. This technique could be used offensively, to shorten the distance of long-range Ninjutsu, disrupt enemies, launch surprise attacks, and transfer targets. It could also be used to evade danger or escape in critical moments. It required no Hand Seals to activate.

But Naruto could now sense changes in space and directly leave Flying Thunder God formulas in the air, achieving invisible instant teleportation. Such movement consumed more Chakra, but its effect was equally obvious: it was very difficult for others to detect the existence of the formula.

After all, the ordinary Flying Thunder God left behind a special mark, whereas Naruto's improved Flying Thunder God Technique could not be sensed by others and was far harder to guard against.

Of course, since Naruto could improve the Flying Thunder God Technique, he had naturally learned the original version as well.

Not only had the speed at which he placed Flying Thunder God formulas increased dramatically, but his movement speed had also become faster.

And when paired with his customized ninja tool, Flying Thunder God: Unlimited Blade Works, he could appear in dozens of different places at the same time.

He had truly achieved that saying: Flash, you can't catch me!

However, he wanted to make his Flying Thunder God Technique more perfect, more powerful, and more stable.

He wanted his spatial perception to become sharper, his spatial control more precise, and his Chakra stronger.

He wanted to turn the Flying Thunder God Technique into his trump card, into a powerful weapon in battle.

Thus, in the days that followed, Naruto continued training in the Flying Thunder God Technique.

He constantly tried to create more complex and stable spatial passages, constantly trying to teleport through them.

His Flying Thunder God Technique became stronger, more refined, and more stable.

His spatial perception became sharper, his spatial control more precise, and his Chakra more powerful.

In the end, Naruto's Flying Thunder God Technique finally reached mastery.

Even with Naruto's top-tier talent and the training boost of multiple Shadow Clones—

It still took Naruto several full days to complete his training in the Flying Thunder God Technique.

Moreover, the reason the Flying Thunder God Technique was called an S-rank Ninjutsu was because it was difficult to learn, not because it consumed much Chakra.

No matter how much Chakra it consumed, Naruto could easily afford it.

To sum it up, Naruto's Flying Thunder God Technique had now completely surpassed Tobirama Senju and Minato Namikaze's.

Naruto knew everything they knew, but they did not know everything Naruto knew.

Naruto could also leave Flying Thunder God formulas on Flying Thunder God: Unlimited Blade Works and continuously use the Flying Thunder God Technique.

He could even consume additional Chakra to directly leave special Flying Thunder God formulas in the nearby space. The more Chakra he consumed, the farther the range.

In other words, as long as Naruto had enough Chakra, he could effortlessly kill enemies within his field of vision!

However, as the distance increased, the Chakra consumption exploded exponentially!

At the greatest range, even Kurama's Chakra was somewhat unable to bear the burden.

At present, using his own Chakra, Naruto could kill enemies at a maximum distance of five hundred meters.

If he used Kurama's Chakra, that distance could be raised to three thousand meters.

That might not seem particularly far, but this was a divine technique that allowed true instant teleportation and swift kills!

The moment you spotted an enemy, they would already be at your side. There was simply no way to defend against that!

And as Naruto's Chakra continued to increase, and his body continued to grow stronger, the amount of Chakra his body could withstand would also continue to rise. This distance still had room to grow!

Still, most of the time, Naruto would keep this move as a hidden trump card. Using it against every random nobody would be far too beneath him.

Only truly powerful opponents deserved to make Naruto use this move!

With the Flying Thunder God Technique, Naruto finally had the capital to venture through the ninja world.

If he could not win, he could just run. After all, no one would expect someone else to know the Fourth Hokage's Flying Thunder God Technique!

Over the following days, Naruto continuously consolidated his Ninjutsu and extracted Chakra.

About three months passed.

By then, Naruto's own Chakra had reached the level of an Elite Jonin. He was only a tiny step away from breaking through to Kage-level Chakra reserves.

Meanwhile, Naruto's Sharingan had unknowingly reached the Double Tomoe stage.

Generally speaking, a Sharingan breakthrough required intense emotional stimulation. But the power of Naruto's bloodline was simply too strong. As his body continued to grow, the power he could withstand also increased. One day, while training, Naruto suddenly felt the tomoe in his Sharingan spin faster and faster, and the Single Tomoe in both eyes directly became Double Tomoe!

Naruto's physical strength was also constantly increasing. Relying on physical power alone, Naruto was confident he could fight Might Guy, without the Eight Inner Gates Technique, to a draw.

Naruto was only six years old. His body had not even reached its full potential yet, but he already possessed such strength. That was no small feat.

And that did not even include the other powers within Naruto's body.

After learning the Flying Thunder God Technique, Naruto finally felt at ease leaving formulas everywhere.

However, Naruto's formulas were specially created by him and differed from the original Flying Thunder God formulas. So even if Minato Namikaze and Tobirama Senju were revived, they would not be able to directly use Naruto's formulas.

After successfully leaving Flying Thunder God formulas throughout Konoha, both large and small, Naruto's sights no longer stopped at Konoha alone.

With Flying Thunder God formulas in place, Naruto could return to Konoha anytime. He only needed to use the Flying Thunder God Technique a few more times.

Under the cover of night, Naruto evaded the patrolling ninja, quietly slipped out of the village, and headed into the deep mountains far from Konoha.

It was for no other reason than to test the Kurama Chakra he had been eagerly anticipating.

At first, he communicated with Kurama and had Kurama evaluate his current physical strength to determine the maximum amount of Chakra his body could withstand.

After making an accurate calculation, Kurama gave Naruto the maximum amount of Chakra.

Naruto's Chakra reserves instantly leaped from Elite Jonin level to the level of an ordinary Kage. This was only because Naruto's body had not finished growing.

Although Naruto's bloodline power was extremely strong, it could not affect his normal growth and development.

According to Kurama's estimate, Naruto would grow much faster than an ordinary child. At around twelve or thirteen years old, his body would be fully developed. At that point, he could undergo more intense training and withstand greater power.

In other words, Naruto could only truly train himself to the limit after reaching twelve or thirteen. For now, he could only restrain his training.

After learning of Kurama's estimate, Naruto understood that even Kaguya Otsutsuki could not have crushed the Third Hokage Hiruzen Sarutobi at the age of six.

Everything in existence had its hidden laws, unless the system stepped in! He still needed to cultivate diligently for a long time.

But that was fine. There was still a long time before the plot began, so he had no need to rush.

And so, Naruto secretly trained for three months. Why three months?

Because the Ninja Academy only held classes for three months before winter break began!

Even the Ninja Academy had time off!
