Nuclear Explosion Technique

"Boom—!"

The earth groaned. The earth trembled.

It was as if the planet's core was struggling to beat like a heart.

And after the extreme light radiation came a visible ring of super shockwaves.

The terrifying shockwave twisted the invisible air into watery ripples, violently hurling every object in its path into the sky and shredding them to pieces!

It spread for dozens of kilometers, still reaching the position where Natsu Yuu and Madara stood.

Fortunately, its power had already diminished countless times, not enough to harm the two.

But if one were closer—

Closer to the nuclear blast's center—

Given the ninjas' high-attack, low-defense stats, they'd likely evaporate instantly.

Even Madara, with his Susanoo activated, couldn't guarantee he'd withstand the terrifying power at the explosion's core.

Watching the distant blast center, Natsu Yuu couldn't help but marvel. This was his first time witnessing a nuclear explosion firsthand.

The sheer impact far surpassed the explosion of a [Tailed Beast Bomb]! Just the sensory experience alone was far more ferocious.

And in terms of actual power, This medium-yield 'Dongfeng Express' was quite impressive.

Whether it could match the Nine-Tails' charged [Tailed Beast Bomb] was debatable.

But it was definitely stronger than an average Tailed Beast Bomb...

Moreover, the most terrifying thing about nuclear weapons wasn't the explosion itself, but the long-lasting nuclear radiation damage afterward.

It was equivalent to a death barrier that could persist for decades, covering a massive area, exterminating all life!

And it required no Chakra to maintain whatsoever.

Thus, anyone attempting to return to this area and rebuild [Iwagakure] would suffer radiation's ravages.

Either wither away here, or flee voluntarily.

Unless someone in this era could research the principles of nuclear energy and radiation, finding a countermeasure would be extremely difficult.

Though it was somewhat cruel, This was exactly the effect Natsu Yuu wanted—a permanent, one-time solution to [Iwagakure]!

Speaking of which, the system's [Modern Item Redemption Voucher] was surprisingly useful.

It could actually redeem a 'Dongfeng Express'!

He'd have to reassess the value of these [Modern Item Redemption Vouchers] and use them more sparingly in the future.

"So, isn't the battlefield clean?"

Natsu Yuu said with a hint of smugness.

"What kind of jutsu is this? It has no trace of Chakra at all?"

Madara was greatly puzzled, deeply shaken.

This clearly defied a ninja's basic understanding.

It was like a magical girl suddenly appearing in reality and casting [Comet Azur] right in front of you—your worldview would collapse if it didn't!

"Nuclear Release: Nuclear Explosion Technique."

"There's such a Release?"

"It's a sage art from another world. Ordinary ninjas would find it very hard to learn."

Madara frowned slightly, still unwilling to give up.

"Even I cannot learn it?"

"This Release is far more complex than an S-rank jutsu. It's difficult for one person to master. If Konoha develops normally, maybe in a few decades, you might stumble upon it."

Madara nodded and stopped pressing.

He was indeed very interested in such a powerful Release, but he wasn't in a rush to learn it immediately.

Slow and steady.

He could always find a way to obtain this power from this [Sage of the Dao Path].

Moreover, in his eyes, Perhaps this was also Natsu Yuu's deliberate show of strength?

A warning that he could easily wipe out an entire ninja village?

With his unfathomable teleportation and such terrifying Nuclear Release, Madara had already elevated Natsu Yuu's threat level beyond Hashirama's.

If he suddenly flashed behind him while he was asleep and unleashed one of these...

He probably wouldn't even have the chance to activate Susanoo!

'Damn bastard, damn Natsu Yuu, don't think you can make me submit with threats like this!'

Madara brooded inwardly, growing more wary of Natsu Yuu by the moment.

But.

He also thought of a new issue.

"With such a powerful Release Technique at your disposal, if you wanted to destroy Iwagakure, why make me do it?"

Natsu Yuu explained casually:

"Sages generally don't meddle too much in worldly affairs. You destroyed Iwagakure—what does that have to do with me?"

Madara was momentarily stunned, gaining a deeper understanding of Natsu Yuu's shamelessness.

'This is what he calls not meddling too much?'

'He's practically one step away from destroying the village himself!'

'And since when do Sages go around calling themselves Sages?'

'Pah!'

'This cunning bastard is probably just as despicable as Tobirama!'

Madara sneered inwardly.

Of course, his expression remained unchanged.

And what Natsu Yuu said was really just an excuse.

In truth, Natsu Yuu couldn't directly commit large-scale slaughter.

The system had a warning: because Natsu Yuu didn't belong to the Shinobi World, he was constantly rejected by it, only able to act normally thanks to the system's concealment.

If he personally killed too many people, the world's rejection would intensify, further hindering the main mission to unify.

These secrets naturally couldn't be revealed.

That's why Natsu Yuu had to prop up a faction, using Konoha's hand to truly destroy the enemy and unify the Shinobi World!

Fortunately, this was only relative.

If any fool really thought they could push him around, Natsu Yuu wouldn't mind sending them all back to the Pure Land.

Gradually, Madara sensed something unusual again.

"Hm?"

"What is this?..."

Under the influence of an invisible force, the physical strength on the surface of his skin began to weaken, and it seemed a very small number of cells were mutating?

Though it was faint, even hard to detect.

But for a powerhouse of Madara's level, his mastery and familiarity with his own body had reached an astonishing degree.

Every subtle change in his body could be clearly and accurately sensed.

He naturally felt the minor damage the Nuclear Radiation was inflicting on him.

"You sense the radiation?"

"What is radiation?"

"An invisible force that continuously weakens a ninja's physical strength. You can think of it as a large-scale barrier that lasts a long time and is hard to resist. Anyone caught inside will gradually rot away until they die..."

Madara roughly understood and couldn't help frowning as he remarked:

"I see. So this is what you meant by 'handling the battlefield.'"

"In that case, no one will be able to rebuild Iwagakure."

"Hmph!"

"To think you have such cruel methods. You're more like a demon than a Sage."

"Even that bastard Tobirama can't compare to you..."

Natsu Yuu shook his head with a wry smile, unbothered.

He had already been restrained—only sending the 'Dongfeng Express' after Iwagakure had been reduced to ruins.

On the road to unification, sacrifices were inevitable.

Natsu Yuu had long been mentally prepared.

Besides, compared to the Third and Fourth Great Ninja Wars started by Madara and Obito, this sacrifice didn't even count as a fraction.

"Enough. Now, are you going to keep your promise?"

Madara stared at Natsu Yuu again, pressing the question seriously.

"Now is not the time..."

He could indeed freely choose the time node to insert into another parallel Shinobi World.

But once you choose a fixed point in time as an anchor, the next time you enter, you can only follow the timeline normally from that anchor onward.

In short.

He could indeed take Madara to see the [Fourth Ninja World War] in [Naruto World 5] right now. But after that, he wouldn't be able to bring anyone to see it again.

So it was better to keep this opportunity for now.

Wait until he had gathered enough spectators, then send them all over at once to watch the match.

Only then would the effect and gains be maximized.

"Such a flimsy excuse. My patience has its limits..."

Madara's tone grew increasingly hostile.

Even knowing he might not be able to defeat Natsu Yuu, he wouldn't allow himself to be toyed with and deceived any longer.

"But taking you to see the future first—that's no problem."

Natsu Yuu changed his tune.

After all, the [Unification Progress] of this [Naruto World 1] had already exceeded 50%, and the system had unlocked certain restrictions.

He could now bring up to two affiliated subordinates from his bound faction to other worlds.

It wasn't yet convenient to take Madara to see the Fourth War, but he could already take him to visit other worlds.

"Oh?"

Madara's eyes lit up, and he was about to say something.

But Natsu Yuu had already activated [World Teleportation], instantly taking him away from [Naruto World 1].
