Naruto The Thunder Calamity

The best time? Raijin let out a helpless chuckle.

How could that be? If it weren't for Black Zetsu, this might actually be the best moment.

But Black Zetsu…

That's someone who can even directly control Madara to resurrect Otsutsuki Kaguya.

Honestly, Raijin couldn't guarantee that if Black Zetsu realized things were going wrong, it wouldn't decide to go all out and control the kid with the Rinnegan to use the Rinnegan's innate abilities.

But that seemed certain.

After all, no matter how things turned out, nothing could be worse than the Rinnegan disappearing.

So, before that happens, Raijin would do everything he could to stop it, but he also had to be prepared to face Madara.

Konohagakure right now didn't have Naruto and Sasuke.

As one of the strongest fighters in the village, these were challenges Raijin had to confront.

One misstep could lead to disaster.

And before the final battle, it was always better to be prepared.

However, Raijin couldn't directly tell Suisei about this.

Not to mention where he got this information, even if he told Suisei he had traveled here from another world, Suisei wouldn't believe it.

So, Raijin disdainfully shot back at Suisei.

"Do you really think those lost dogs can surpass Konohagakure in the same amount of time?"

Suisei was taken aback, opened her mouth to say something, but couldn't find the words.

Yeah, the group gathered around him looked strong, but in reality, they hadn't defeated Konohagakure back then and surely wouldn't stand a chance against them now.

Especially since Raijin had opened up new paths.

With her being a traitor, there was really no reason for Konohagakure to lose.

If Konohagakure were to lose to the enemy, the only possibility would be if internal conflict started now and lasted for many years.

And during that time, most of the strong fighters from Konohagakure would have to die.

Especially Uchiha Raijin.

But if it really came to that, Suisei might actually have to carry out the Eye of the Moon plan, taking the power he currently had to Konohagakure to forcibly capture the Nine-Tails, Eight-Tails, and Two-Tails.

However, such a thing was nearly impossible. Right now, the Senju and Uchiha clans were in one of the closest relationships in ninja history.

As long as the Senju and Uchiha didn't fall apart, Konohagakure wouldn't fall into chaos.

"Don't think too much about it. From now on, I'll come here every day at this time to help you practice Senjutsu. When you're alone, don't try anything recklessly," Raijin said to Suisei.

The future is uncertain, but for now, training in Senjutsu is really quite dangerous.

Take Orochimaru as an example. Although Raijin guided natural energy to circulate within Orochimaru's body, 

even after that, Orochimaru still lacks the ability to practice Senjutsu on his own. 

Because even the tiny bit of natural energy stored in his dantian is hard for Orochimaru to control. 

The dangers of natural energy flowing through the meridians go without saying. 

If there's too little, it won't work; if there's too much, it could cause bleeding from the orifices and sever the chakra path.

So, even though Raijin is extremely annoyed with this mind-numbing task that requires intense concentration, 

he still has to keep doing it for a long time to come. 

After all, Raijin is currently the only one in Konohagakure who can do this. Not only that, but for now, the future limits of Senjutsu are still unclear. 

However, the recent goal is the Eight Inner Gates. 

The idea is to enhance physical and mental energy through Senjutsu until it can withstand the power of the Eight Inner Gates.

This way, he can completely master the Eight Inner Gates in a stable state. 

Just think, when everyone in Konohagakure becomes as powerful as Guy, what could Uchiha Madara do? No, even if he were Six Paths Madara, it wouldn't matter. 

So, in Raijin's view, when the Uzumaki clan is helpless against the curse mark on Suisei, Senjutsu might be the only way for Suisei to regain her freedom. 

After all, it's not like Kakashi can really use a heart-piercing method to lift the curse mark, right? 

Honestly, with the little medical knowledge Raijin has, a person can't survive without a heart.

"Are you really that worried about me?" 

Suisei raised an eyebrow at Raijin, a teasing smile on her face.

"You're the last one to learn Senjutsu."

Raijin rolled his eyes at Suisei's remark, then instantly vanished from the spot. 

When Flying Thunder God Jutsu meets Kamui, it creates a wonderful effect, allowing Raijin and Suisei to meet anytime and anywhere without anyone knowing, 

including Black Zetsu.

The Insect Technique can hide underground, but it can't enter Kamui space. 

After all, Black Zetsu isn't a void-dwelling beast. 

Seeing where Raijin had stood, Suisei couldn't help but smile. 

No matter if he is the last one to learn Senjutsu, at least Raijin cares about him. 

The reason he doesn't want to start a fight right now is that he wants Suisei to stay alive.

Besides that, Suisei really couldn't think of any other possibilities.

Although this organization seemed large, it was actually no match for Konohagakure.

If Raijin wanted, with the information he had, Konohagakure could achieve victory in at most half a month.

This half month even counted the time spent by the Konohagakure ninjas traveling back and forth.

So, besides wanting to save himself, what other reason would Raijin have for confronting this organization?

"Ha~"

Slowly exhaling a breath of stale air, Suisei lay on the ground and closed her eyes.

…

As the only person in Konohagakure capable of guiding natural energy through the body, Raijin was very busy.

Raijin needed to help everyone in need walk the path of independent Senjutsu training.

But this wasn't difficult since it was a path that was easy to see the end of.

It just required a relatively long time.

So, for the next whole year, Raijin focused on this task.

During this process, Raijin also opened up all the meridians in his body and successfully made permanent Senjutsu.

The next goal was to strengthen his body enough to handle the Eight Inner Gates formation, opening the last eight chakra points.

This would result in a significant increase in his power.

However, this would take a long time.

During this process, Tsunade officially became the Third Hokage of Konohagakure under the recommendation of Senju Tobirama.

Konohagakure, Senju clan's land.

Raijin looked at Senju Tobirama, who had completed a cycle by himself, and a relaxed expression appeared on his face.

"Congratulations, Grandpa."

"You've worked hard during this time."

Senju Tobirama chuckled and shook his head in response to Raijin.

"We're all family; you're too polite."

Raijin smiled slightly and said to Senju Tobirama.

"Hmph, I thought you were different from the other Uchiha a long time ago, and now it seems I was right."

Senju Tobirama nodded with satisfaction as he looked at Raijin.

The investment in Raijin back then had unexpectedly paid off today.

"Now that Tsunade has become Hokage, you've been busy with Senjutsu for the past year. Now that this matter has come to a close, what are your plans next?" 

Senju Tobirama adjusted his sitting position and asked Raijin.

"Recently, I've gained some new insights about the Sharingan, so I'm planning to study it next," 

Raijin said to Senju Tobirama. This realization came after Raijin's mental power reached a certain level.

"Oh? Can you share more?" 

Senju Tobirama responded with curiosity, intrigued by Raijin's words. 

To be honest, there aren't many techniques that can pique Senju Tobirama's interest these days. 

Currently, the only thing that truly interests him is Senjutsu, as it is completely independent of chakra. He has a strong curiosity about it. 

Before, he didn't have a solid foundation to study it, but now he feels ready to start. 

Having stepped down from the position of Hokage, Senju Tobirama is now the head of the research center in Konohagakure. 

Besides Senjutsu, his greatest interest lies in the Uchiha's Sharingan.

"With my improved control, I've recently been able to notice the changes in the eye power when the Mangekyou Sharingan activates," 

Raijin continued to explain to Senju Tobirama. 

This discovery fascinated Raijin. 

Strictly speaking, the eye power used to activate these techniques is a separate, fourth power system, distinct from Senjutsu and Ninjutsu, as well as the Rumble Fruit. 

Raijin has achieved the goal of combining the three techniques, and he is very interested in developing this fourth power system. 

"So, you want to develop other Sharingan techniques?" 

Senju Tobirama quickly understood Raijin's intention and asked.

"Yes, I think since I've observed the changes in eye power when activating the Sharingan techniques, can I also develop other techniques by observing the changes in eye power of different techniques?" 

Raijin smiled lightly and explained to Senju Tobirama. 

"That's a great idea; you should give it a try," 

Senju Tobirama nodded in agreement. He believes that the eye power of the Sharingan comes from the Uchiha clan's intense mental fluctuations, which stimulate a specific part of the brain, generating a unique energy.

When this energy reaches a certain level, it causes the Uchiha's eyes to mutate. 

Thus, this energy is referred to as eye power. 

When eye power increases significantly in a short time, it leads to the upgrading of the Sharingan, from a single Tomoe Sharingan to the Mangekyou Sharingan. 

Especially with the Mangekyou Sharingan, according to Senju Tobirama's observations, the techniques it possesses are influenced by the emotions felt before opening the eyes.

In other words, whatever an Uchiha desires most before awakening their Sharingan is often what the Sharingan helps them with the most after awakening.

That's why the Sharingan is also known as the "mirror of the heart."

And since each Uchiha's desires before awakening are different, it leads to every Mangekyou Sharingan having a unique pattern.

On the flip side, it can also be said that because the patterns are different, the eye techniques within each Mangekyou Sharingan are different as well.

If the essence of eye power is the same, then does that mean, by changing the way the eye power operates within the Mangekyou Sharingan, the pattern of the Mangekyou could change, and in turn, the eye techniques housed within it could also change?

Senju Tobirama believed this was possible.

Senju Tobirama shared his thoughts completely with Raijin.

Raijin was already very strong, and Senju Tobirama didn't mind helping him grow even stronger.

After all, Senju Tobirama thought that Konohagakure would likely face the threat of Uchiha Madara in the future.

So the stronger Raijin became now, the better the chances of Konohagakure's victory in the future.

"It's really hard to imagine that you know even more about the Sharingan than I do."

Raijin chuckled at Senju Tobirama's words. You had to hand it to him—he really was a master of forbidden techniques, understanding the Sharingan inside and out.

"Heh… so, how about it? Has the natural energy healed the drop in strength caused by using your eye techniques?"

Raijin knew why Senju Tobirama understood the Sharingan so well, so there was no need to explain it.

No matter how the relationship between the Senju and Uchiha had been in the past, as of now, they were allies.

Allies connected by marriage.

Among the ninja clans in this world, a marriage bond was far stronger than any shared ideals.

Especially since the feelings between Tsunade and Raijin were still very strong.

"It's healed, and I've even gained a slight boost in power because of it."

Raijin didn't hide anything and told Senju Tobirama directly.

At this point, Raijin had no reason to keep his strength a secret.

In this ninja world, aside from Uchiha Madara, who could revive at any moment, no one posed a lethal threat to Raijin anymore.

"Hmm, it seems Senjutsu really boosts an Uchiha's power."

Senju Tobirama nodded, a fleeting hint of envy flashing through his eyes.

To the Senju clan, the Uchiha are really poor. 

Whether it's in their Ninjutsu knowledge or Summoned Beast inheritance, 

the Uchiha can't compare to the Senju. 

However, with the Sharingan, they completely closed that gap. 

Now, with the development of Senjutsu, it has opened up endless possibilities for the Uchiha in a simple yet powerful way. 

So, where does Senjutsu enhance the Senju clan? Simply improving physical abilities isn't much needed anymore. 

After all, like Raijin, who is now developing different eye techniques, once he succeeds and records the routes of how the eye power flows for these techniques, 

in the future, all Uchiha who awaken the Mangekyou Sharingan will be able to master various eye techniques. 

That kind of improvement would be terrifying. 

As Senju Tobirama knows, each technique residing within the Sharingan far surpasses even S-rank Ninjutsu. 

Thus, Senju Tobirama now feels an urgent need to develop more techniques for the Senju clan. 

A technique that can rival the Uchiha's Susano'o. 

Fortunately, the existence of Senjutsu has greatly improved his physical abilities. Without it, even with such determination, Senju Tobirama would find it hard to complete. 

Senjutsu has given Senju Tobirama enough time. 

And with this time, he can create one miracle after another. 

"It's quite something. You could even use natural energy to replace negative emotions to generate eye power," 

Raijin said with a light smile, continuing his conversation with Senju Tobirama. 

Honestly, ever since permanent Senjutsu development was successful, the results have been astounding. 

Right now, Raijin is absolutely in love with Senjutsu. 

Hearing this, Senju Tobirama pressed his lips together and stayed silent for a while. 

Raijin's words only strengthened Senju Tobirama's resolve to develop a technique that can rival Uchiha's Susano'o. 

In Senju Tobirama's view, under the influence of Senjutsu, the Uchiha might eventually become a clan where everyone has Mangekyou Sharingan and masters more than three eye techniques each. 

Even though this process might be very slow. 

But compared to that, the Senju clan is not only equally slow, but they don't even have a clear goal. 

Not every Senju can just develop Wood Release on their own, like Tsunade did. 

Within the Senju clan, there were very few who could match Tsunade's chakra control.

Because of this, Senju Tobirama felt a heavy burden on his shoulders.

"Alright, go and rest for now. The future of Konohagakure will be in your and Tsunade's hands."

After glancing at Raijin, Senju Tobirama completely lost the desire to continue talking with him.

At this moment, all Senju Tobirama wanted was for Uchiha Raijin to disappear from his sight.

Even Senju Tobirama couldn't help but grit his teeth at how easily the Uchiha seemed to win.

"Alright, you rest first. I'll be heading back now."

Raijin nodded slightly, a gentle smile on his face.

Raijin was in a good mood. With everyone around him now able to train in Senjutsu on their own, he could finally free himself from his busy schedule. In the future, his life would become much more relaxed.

Watching Raijin suddenly disappear before him, Senju Tobirama snorted coldly with disdain.

Rest? Only those who are useless to Konohagakure would rest.

Closing his eyes slowly, Senju Tobirama began to contemplate techniques that would suit the Senju clan.

In comparison, the physical abilities of the Senju clan were unique, not only in Konohagakure but in the entire ninja world.

This meant that the Senju's Yang Release was especially powerful.

And a technique related to Yang Release that could rival the Uchiha's Susano'o…

Suddenly, Senju Tobirama thought of the Akimichi clan's body expansion jutsu.

At that moment, his mind cleared, and a new idea formed in his head.

In the next second, Senju Tobirama vanished from the Senju compound and reappeared in Konohagakure's research center.

Having stepped down from the position of Hokage, Senju Tobirama felt a long-forgotten sense of joy standing in front of the experiment table again.

Come to think of it, ever since becoming Hokage, it had been a long time since he last developed a new jutsu.

But now, standing in front of the experiment table again…

Senju Tobirama pressed his lips together, a clear look of joy on his face.

It was truly...

"Knock, knock, knock."

At that moment, a series of knocks suddenly echoed, and Senju Tobirama, a bit surprised, turned his head to see Orochimaru peeking in.

Senju Tobirama didn't say anything, just blinked in slight confusion.

"Hello... Hokage-sama... I just wanted to ask... do you need an assistant?"

Facing Senju Tobirama's gaze, Orochimaru, unusually nervous, stammered out the words and waited eagerly for Senju Tobirama's response.

"Before I answer your question, can you first tell me how you knew I was here?"

Senju Tobirama smiled lightly, easily seeing through the nervousness hidden beneath Orochimaru's hopeful expression.

Honestly, there was no problem with making Orochimaru his assistant. 

Like Jiraiya, he was also a civilian ninja of the Seventh Squad.

Despite not being able to learn Senjutsu, he had successfully developed the Decay Technique.

And after the war, the Ninja Tools he developed for Raijin were further proof of Orochimaru's talents.

He was a child with exceptional talent in Ninjutsu. 

Senju Tobirama had a very good impression of Orochimaru. 

Most importantly, even though Orochimaru had made great contributions during the Second Shinobi World War, he hadn't asked the village for any rewards.

It was important to note that Orochimaru was different from Raijin. Raijin didn't ask for any rewards because he didn't need them. 

His beloved granddaughter had already secured everything Raijin needed even before he made his mark.

But Orochimaru didn't have such a privilege.

So, Senju Tobirama didn't mind making Orochimaru his assistant.

Still, he was curious.

How did Orochimaru know he was in the lab?

After all, he had arrived here using the Flying Thunder God Jutsu.

In theory, no one should have known he was here.

"A small, insignificant technique, that's all. I've been waiting for you here for quite a while."

Orochimaru smiled shyly, feeling a bit embarrassed.

Orochimaru had admired Senju Tobirama for a long time.

Now that he had mastered Senjutsu and Senju Tobirama had more time, Orochimaru thought this was the perfect opportunity to meet him.

"Come in, then."

Senju Tobirama smiled, slightly surprised, nodded, and waved Orochimaru inside.

Hearing this, Orochimaru's face immediately lit up with a happy smile.

He opened the door and quickly ran over to Senju Tobirama's side.

At that moment, Orochimaru felt like a dream had come true.

What's power compared to this? Are techniques really that important? 

What's a technique compared to working with the master of forbidden jutsu?

Being able to study jutsu with the master of forbidden jutsu—that's the greatest luck!

…

"Are you still busy? Hokage-sama?"

In the Hokage's office, Raijin poked his head in, seeing Tsunade completely buried in paperwork. He asked softly.

"Hmm? You're back? Did he succeed?"

As soon as Raijin spoke, Tsunade's head popped out from behind the pile of papers. A document was even stuck to the right side of her face.

Standing up, Tsunade quickly realized what had happened. She swiftly pulled the paper off her face and gave Raijin an awkward but polite smile.

"It worked."

Seeing this, Raijin couldn't help but laugh and shared the good news with her.

"Took him this long to finally get it right, what an old fool," Tsunade scoffed when she heard the news, clearly unimpressed.

At the same time, a mysterious smile appeared on her face. She ran over to Raijin, hugged his arm, and gently shook it.

"So, does that mean you don't have much to do now?" 

Tsunade blinked at Raijin, asking with a playful look.

"Uh… I guess?" 

Looking at her, Raijin suddenly felt a strange sense of foreboding rising inside him.

Tsunade's smile became even sneakier when she heard that, and she finally said what she had been wanting to say for a while but hadn't had the chance to.

"Then help me out, won't you?"

That's reasonable, right? Personally, I don't think it's a big deal. If anyone has any thoughts, feel free to leave a comment.
