Naruto The Thunder Calamity

As a successor to the Sage Of Six Path Eyes, Uchiha gained unrivaled Sharingan techniques, incredible Genjutsu, and exceptional agility. 

However, in terms of pure physical strength, even against the Senju, Uchiha would be overpowered.

Senjutsu, developed by Uchiha Raijin and Tsunade, is a permanent form of Senjutsu that enhances both physical abilities and mental strength.

In addition to these enhancements, Senjutsu's recovery capabilities stand out more.

In other words, combining Senjutsu training with enough Taijutsu practice makes the effects more obvious.

The recovery traits of Senjutsu were best demonstrated by Might Duy.

But even though Senjutsu can enhance physical strength and mental energy, the efficiency of these enhancements depends on the individual's base attributes.

Taking the Senju and Uchiha as examples:

Even though Senjutsu can boost mental strength, the Senju clan can never surpass the Uchiha through Senjutsu alone.

Similarly, Uchiha can never surpass the Senju in physical strength using Senjutsu.

So...

Does this mean they'll always be at a disadvantage?

Lying weakly on the bed, Raijin felt utterly exhausted, with sharp pain constantly shooting through his waist, making it hard to even open his eyes.

This is unbearable! I need to surpass Tsunade in physical strength. If this continues, I'll eventually die.

After the last fight, Raijin understood.

There's no shortcut for this.

That was close—my finger almost broke! But if Senjutsu can't do it, then where should I start?

"Hashirama cells?"

No, just the cells alone might not be enough.

After all, a portion of Hashirama's cells might not have much effect on his current self.

With the influence of Senjutsu, his physical condition had already been greatly improved.

Unless he were to devour all of Senju Hashirama's cells, the increase in his physical strength wouldn't actually be that significant.

So, he needed to pursue even stronger power.

Kinkaku, Ginkaku...

A name echoed in Raijin's mind.

The legendary man with Otsutsuki blood, but of course, just Kinkaku and Ginkaku alone wouldn't be as effective as Hashirama's cells.

However, what if paired with the giant Tenseigan on the moon?

But if Otsutsuki blood was necessary, wouldn't Otsutsuki Toneri be a ready candidate?

But if devouring Otsutsuki Toneri could absorb the giant Tenseigan, why didn't Toneri just do it himself?

Sigh... Maybe I should think of a way to release Otsutsuki Kaguya and devour her using the Kageyama Jutsu...

"Let's eat something first."

Just as Raijin was pondering ways to become stronger, Tsunade's voice sounded in his ear.

In the next moment, Raijin felt himself being lifted.

"Thank you for your hard work."

Looking at Raijin, whose eyes were half-closed, resting against her chest, a smile appeared on Tsunade's lips.

It really was... delicious... I want more...

Tsunade gently swallowed and placed a bowl of black, unidentified liquid near Raijin's mouth.

"Open your mouth."

Raijin opened his eyes upon hearing this and glanced at Tsunade. Without thinking, he opened his mouth. The next moment, a bitter taste immediately spread in his mouth.

Wow, this taste is almost as bad as the Thunder Fruit!

"Ugh!"

Raijin instinctively wanted to spit it out, but Tsunade was faster, full of energy.

"Mmm!!"

Tsunade's lips sealed Raijin's mouth, and he instinctively pushed her shoulder with both hands.

Ha! What a joke, I can't push her away!

In that moment, only one thought remained in Raijin's mind.

The medicine is poison, and the poison is deadly, I'm going to die...

Until Tsunade's hand started moving inappropriately.

"Hey!"

Raijin grabbed Tsunade's wrist, taking the brief opportunity when their lips parted to speak.

"There's nothing, really..."

"Shh~"

Tsunade raised a finger to her lips, signaling Raijin to be quiet.

"There is."

Tsunade blinked and said gently to Raijin.

"I know my body well."

Raijin furrowed his brow and said to Tsunade.

"I'm a doctor. I understand your body better than you do."

Upon hearing this, Tsunade lowered her finger from Raijin's lips, gently placing it on his chest.

Slowly, her hand moved down to his stomach.

"See for yourself."

As Tsunade spoke, Raijin felt a warm flow slowly gathering in his lower abdomen, then spreading outwards, easing the sharp pain in his waist.

It really seems... to be working...

Raijin blinked in disbelief, staring at Tsunade.

"Don't worry. This is a herb from Shikkotsu Forest that contains natural energy. There are no side effects."

Tsunade winked at Raijin and said.

Tsunade wasn't foolish; she wouldn't do something reckless like overusing her own energy.

"But... It's been over a week, shouldn't it be enough by now?" 

Raijin blinked and asked Tsunade.

"I'm sorry, but I'm on my period right now." 

Tsunade chuckled upon hearing this, not caring whether Raijin believed her or not. She immediately pressed herself against him. 

... 

Clouds gathered and scattered, time changed. 

In the blink of an eye, nine years passed by. 

This broken world, thanks to Konohagakure, had gained a new kind of brilliance. 

For the people of Konohagakure, since the Second Great Ninja War, every day in the village had seen different changes. 

The most obvious change was that, without working too hard, children could receive a good education. 

Without working too hard, they could get enough food and even save a lot of money. 

If Senju Tobirama's time had laid a solid foundation for Konohagakure's prosperity, then the presence of Raijin and Tsunade had turned this foundation into a towering structure. 

And this was just the improvement in Konohagakure's overall strength. 

However, no matter how outstanding the children trained at the ninja school were, they represented the future, not the present. 

No matter how skilled a Genin was, they were still just a Genin. They were far from being able to take on an absolute opponent. 

The group of Konohagakure's elite, gathered by Tsunade as the Hokage Guard, had also made significant progress over the years. 

Raijin, for example, had managed to master Senjutsu to the point where he could keep the Fourth Gate open permanently while balancing his duties and taking care of his child. 

Not only had his strength and speed increased significantly, but he could also gather a large amount of Senjutsu chakra in a short period. 

Yes, even though Raijin and Tsunade had developed permanent Senjutsu, after many combat simulations, the conclusion was clear. 

Neither pure chakra nor pure natural energy was as powerful as Senjutsu chakra, which was a combination of both. 

Although the first stage of Senjutsu wasn't fully mastered, Raijin felt that the second stage of Senjutsu should focus on chakra. 

But no matter what, Raijin felt ready to tackle something now. 

The thing that had been bothering Raijin, preventing him from taking action against Black Zetsu. 

As Tsunade said, time was long, and after all this time spent exploring, Raijin was now confident he could help Suisei lift the curse mark. 

In Suisei's Kamui space, Raijin and Suisei sat across from each other. 

"Ah... Are you sure you can do it? I haven't even met your child yet." 

Suisei instinctively licked the corner of her mouth, feeling a little nervous. 

To be honest, Suisei still wanted to live. Taking Raijin's child as an apprentice and watching the new generation grow stronger little by little would be amazing. 

"Ah... this is my first time too. If I succeed, you'll live. If I fail..." 

Raijin paused here, a bright smile spreading across his face. 

"Then I guess I'll die." 

As he spoke, Raijin put his hands together, a deep purple shadow appearing at the corner of his eyes. 

At this moment, Raijin entered Sage Mode. 

The First Gate of the Eight Inner Gates continued to activate its effects. 

A faint, nearly invisible trace of natural energy, barely detectable to the naked eye, touched Suisei's chest as Raijin placed his hands there. Slowly, it entered her body. 

Through her chest, the natural energy gradually reached Suisei's heart. 

Natural energy slowly flowed into Suisei's heart. Without directly helping Suisei open the door to death, Raijin controlled the natural energy to protect Suisei's heart from the inside out.

Although the pressure of the Senjutsu chakra caused the curse seal on Suisei's heart to react instantly, the black markings wrapped around it. However, the barrier formed by the Senjutsu chakra prevented the curse seal from doing anything at this moment.

It was at this time that Raijin's hand, which was placed on Suisei's chest, began to move slowly.

While stabilizing the natural energy and keeping the curse seal in a tug-of-war, he only allowed his two fingers to gently press against Suisei's chest.

…

While Suisei and Raijin were still figuring out how to break the curse seal, Black Zetsu wasn't idle either.

Late at night, Black Zetsu slowly appeared in Uzumaki Nagato's room.

Looking at Uzumaki Nagato, who had just finished his training and was now fast asleep, Black Zetsu's eyes flashed with a hint of determination.

Honestly, Black Zetsu didn't want to give up on Nagato so soon.

In the original plan, Nagato was supposed to fulfill his full purpose in the fight against Konohagakure before dying.

But now, that was no longer possible.

Uchiha Suisei was unreliable.

If things continued this way, it would be very troublesome.

So, today, Black Zetsu decided to wake up Uchiha Madara ahead of schedule.

Without Uchiha Madara, Black Zetsu found it hard to sleep.

Silently, Black Zetsu crept closer to Uzumaki Nagato.

"Uh…!"

In his sleep, Uzumaki Nagato suddenly woke up, a strange sensation sweeping over his body, and he tried to move.

But Nagato realized that he couldn't do anything.

It was as if his limbs had developed a mind of their own and were no longer under the control of his brain.

Not only that, but his hands also began moving on their own, forming hand signs that he had never seen before.

This…! 

Uzumaki Nagato's eyes widened in shock, and his Rinnegan began spinning rapidly.

However, this wasn't Nagato's doing.

Outer Path: Samsara of Heavenly Life Jutsu!

A coffin slowly rose from the ground. As the coffin opened, Uchiha Madara, dressed in crimson battle armor and holding the Uchiha fan, emerged.

After years of preservation by Black Zetsu, Madara's body showed no signs of decay.

And as Uchiha Madara's body was exposed to the air, a green glow immediately covered it.

"Heh… heh…"

Uzumaki Nagato let out a few meaningless syllables from his throat.

Feeling his life force rapidly draining with no way to stop it, a giant figure of the King of Hell appeared in the air.

Its mouth opened wide, and Uchiha Madara's soul emerged from it.

At this moment, Uchiha Madara was resurrected!

...

Two fingers pressed against Suisei's chest. In Raijin's other hand, a Kunai silently appeared.

Wind Release chakra instantly enveloped the Kunai. Without hesitation, Raijin thrust it toward Suisei's chest.

The Kunai pierced through the curse seal on Suisei's heart and continued its way toward the heart with unrelenting force.

"Clink!"

A sharp sound rang inside Suisei's body, and the intense pain made Suisei roll his eyes back.

Luckily, Raijin had already used a barrier made from Senjutsu chakra to block the Kunai.

Of course, this was also greatly influenced by Raijin using his Sharingan technique, to remove the wind chakra wrapped around the Kunai at the moment it was about to pierce his heart.

"I have to say, I'm impressive. My reaction time is really fast."

Raijin thought to himself happily, looking up at Suisei, and he couldn't help but sigh in relief.

The joy inside him made his mouth unconsciously curve into a smile.

"Good job, Raijin."

Suisei, holding her chest, slowly stood up. A bright green light radiated from her hand as she spoke to Raijin.

"It was tough."

Raijin nodded and wiped the sweat from his forehead that he hadn't noticed was there.

"Let's go. Now we can take care of those pests."

Suisei glanced at Raijin, then reached out to draw her long sword. Her Mangekyou Sharingan, blood-red and filled with killing intent, stared ahead.

Raijin, hearing her, gave a noncommittal nod and didn't bother to exit Sage Mode.

At his current state, Sage Mode could last for a long time.

With four out of the eight gates of The Eight Inner Gates opened, Raijin could maintain full combat in Sage Mode for at least a whole day and night.

…

"Oh? The seal was broken?"

Uchiha Madara casually dug out the Rinnegan from Uzumaki Nagato's eye socket and placed it on his own face, muttering softly.

"You're quite capable."

No more wasting time. Let's get to it.
