Naruto: I, who fooled the ninja world, was hailed as a savior.

Chapter 321 Lightning Release: Railgun
The once clear riverbank was now a mess.

A noticeable depression was blasted open in the middle of the river, and the turbid river water, carrying silt, slowly filled it back in. Several fish that had been stunned by the electric shock floated on the surface, their gills still slightly open and closed.

The air was filled with moist mist from the vaporization of river water, and a pungent smell of ozone from the air being electrified.

The grass along the riverbank was scorched black by the stray arcs of electricity, and the branches and leaves of the nearby trees were also somewhat withered, showing the power of the attack.

"Huh...huh..."

Uchiha Sasuke emerged from the edge of the forest, looking somewhat disheveled, his face covered in dust, his hair disheveled and sticking up, and he tightly gripped the longbow called 'Holy Annihilation Arrow' in his hand.

Clearly, before he succeeded, he was often affected by his own out-of-control lightning chakra.

However, when he saw the still-jumping arcs of electricity on the river and the scene of destruction, he couldn't help but feel excited.

He turned to look at Naruto beside him, and exclaimed incredulously, "Your 'electromagnetic induction' actually works?"

This is far more terrifying than the power of an arrow he simply condenses with chakra!

He simply taught Naruto the "Shadow Clone Technique," but unexpectedly, Naruto created this Lightning Release ninjutsu specifically for him.

Although the "Shadow Clone Technique" is also a precious B-rank ninjutsu, it is completely incomparable to this ninjutsu that is unique to him!

"Indeed, the theory is feasible."

At this moment, Naruto was not as excited as Sasuke.

He stared at the remaining arcs of electricity on the river, his face showing a thoughtfulness beyond his years.

This was also the first time he applied the knowledge he learned from books to ninjutsu.

If this knowledge can be combined with chakra, why can't it be applied to a wider range of fields?

Why has this magical energy of chakra been used only for killing, fighting, and destruction for thousands of years?

It shouldn't be like this.

Chakra should not be merely a weapon for killing, but rather a tool for creation and an energy source for the advancement of civilization.

It could clearly be used to clear mountains and build roads, speed up transportation, and even change the environment and create resources...

Throughout the history of the ninja world, numerous wars have been waged under the pretext of "unequal distribution of resources."

However, chakra can be used to make the "cake" bigger, create and develop more usable resources, and ensure that everyone can have enough to eat.

It's probably normal for a ninja who only knows how to kill to not think of these things.

But did those commoners, those merchants, those nobles, and that famous man really not expect this?
If you can figure it out, then why hasn't the ninja world made any progress in the application of chakra over the past hundred years?
Although this will raise the status of ninjas, the benefits it brings are far greater. As the leader of a country, the daimyo should not be so short-sighted, right?
It should be, right?

His teacher gave him many books, and he knew a lot about that world without chakra, but his understanding of the ninja world was ultimately limited to a few books.

In his view, the daimyo is, after all, the leader of a great power. Even if he is not as good as the leader of that world, he shouldn't be too much worse, right?
Although I felt that Daimyo wouldn't do that, once the thought arose, it spread like wildfire.

What if the problem really lies with those famous people?
"Hey," Sasuke called out again, "What are you thinking about?"

Hearing Sasuke's words, Naruto snapped out of his reverie, shook his head, and said, "I just came up with an idea; the principle isn't actually that complicated."

In his vision, this ninjutsu should have four stages.

First, the first stage: [Activation of Thunder] and [Gravification].

The activation of lightning requires Sasuke to spread lightning chakra throughout his body, and then condense it into an arrow using that longbow, so that it achieves perfect electromagnetic compatibility.

Magnetization is achieved by changing the polarity of chakra, turning the arrow itself into a magnet and endowing it with a powerful and stable inherent magnetic field.

This forms the basis for all subsequent electromagnetic effects.

Then, the second stage, [track construction].

Sasuke needs to use that longbow with its excellent chakra conductivity to create an invisible acceleration track formed by lightning chakra.

The orbit needs to be built with an alternating electromagnetic field, essentially a small "linear electromagnetic induction accelerator".

This is the core of the technique. Then, the third stage, [Electromagnetic Jet], is the first acceleration.

The powerful electromagnetic force at the front of the track generates a strong repulsive force on the magnetized arrow, similar to how like poles of a magnet repel each other, while the rear of the track generates an attractive force, similar to how opposite poles attract each other.

This push and pull, over an extremely short distance, can provide the arrow with terrifying initial kinetic energy, even enabling it to reach an initial velocity of three times the speed of sound.

Of course, Sasuke Uchiha is not yet able to do all of this perfectly.

They made nearly a hundred attempts, and Sasuke almost exhausted his chakra, but they only succeeded once, and even then, they barely achieved the effect of the third stage, which was extremely unstable.

The final fourth stage, [Magnetic Guidance], is the essence of this ninjutsu, involving continuous acceleration and correction during flight.

After the arrow leaves its trajectory, its inherent magnetic field will continuously induce electromagnetic induction with the air and the residual chakra field of the caster.

According to Lenz's Law, which his teacher taught him, this would generate a force that would prevent the arrow's velocity from decreasing and could even accelerate it.

Although the physical acceleration effect is limited, with the intervention of chakra energy, the arrow will continuously absorb the chakra gathered by the caster during flight to continue to increase its speed.

The power and speed will change depending on the chakra infused by the user.

This is what is known as "magnetization".

At the same time, by maintaining a chakra connection with the arrow's inherent magnetic field, the caster can perceive the arrow's location with the precision of radar.

It can adjust the electromagnetic field generated by Lightning Release chakra, applying a lateral "pull" to the flying arrow, like an invisible hand, fine-tuning its trajectory.

Ensure that attacks can hit moving targets, instead of only being able to attack in a straight line as they are now.

This is what is known as "guidance".

"To complete this technique, the requirements for the form and nature transformation of Lightning Release chakra are extremely high, and the ninja tools must be able to withstand instantaneous high temperatures and electromagnetic loads and have conductivity."

Naruto looked at Sasuke's Sharingan, then looked down at his longbow, and continued, "Your three-tomoe Sharingan has excellent nerve response and dynamic vision."

"Furthermore, the key to the success of this technique lies in the superior chakra conductivity and high heat resistance of this ninja tool."

Seeing his dissatisfied expression, Sasuke Uchiha's lips twitched, and he said irritably, "It's already very strong, okay? This is practically an instantaneous, no-seal ninjutsu!"

"The last person to develop a ninjutsu without hand seals was the Fourth Hokage! You're simply a genius at developing ninjutsu!"

Sasuke had even started to think about how this ninjutsu could be further developed.

Once his Lightning Release chakra's form and nature transformations have advanced further,
He could easily simplify this ninjutsu, abandoning the longbow, magnetizing his body, and using his arms as a "bow and crossbow" to condense lightning chakra arrows.

Alternatively, one could sacrifice power by firing smaller, more numerous arrows in succession, or split a single arrow into multiple, thinner "sub-arrows" to create a wide-area attack.

"However, Shisui-nii is not good at lightning release after all, so it's already quite remarkable that he can guide me to this extent."

Sasuke frowned slightly, pondering, "Who else in the village is proficient in Lightning Release? Kakashi Hatake? He seems to have an S-rank Lightning Blade..."

"And, Hyuga Kumokawa?"

"Unfortunately, this technique has too high a barrier to entry and lacks universal applicability..." Naruto's thoughts jumped elsewhere, "No, what if it were applied to transportation..."

He fell into deep thought, muttering words that sounded like gibberish to Sasuke: "Linear motor... energy efficiency... friction..."

Naruto was talking to himself when, after a moment, he suddenly noticed that it was unusually quiet beside him and that Sasuke was not responding.

He subconsciously looked up, only to see that Sasuke's expression had become somewhat stiff, and his eyes looked slightly vacant.

"What's wrong?" Naruto asked, puzzled.

"..." Sasuke slowly came back to his senses, his eyes twitching slightly, and he said helplessly, "The shadow clone left at school was destroyed."

Upon hearing this, Naruto paused for a moment, then his face showed pity.

Prepare to face Iruka-sensei's wrath.
