The First Hokage's Ultimate Ninja Tool

Shimura Kentei had anticipated Jiraiya's doubts and patiently explained, "To change the ninja world, one must possess immense power as support. This power must be on the level of the First Hokage and that Uchiha."

"Only with power at that level can one suppress the entire ninja world, make all ninja villages and shinobi heed his words, and thus bring peace to the ninja world."

"And within Konoha today, and even among all ninja clans in the entire ninja world, only the Senju Clan and the Uchiha have the potential to reach that level."

These words caused Jiraiya to fall silent. He inwardly agreed with his convenient disciple's analysis, but he was still very displeased.

"Why must it be someone from a ninja clan? Can't commoners do it?"

As soon as the words left his mouth, Jiraiya knew he had spoken out of turn. It was indeed a foolish question.

Ninja training heavily emphasized bloodline and origin. Without a good bloodline inheritance, one was almost entirely cut off from the word "strong."

Looking speechlessly at Jiraiya lying on the sickbed, Shimura Kentei crossed his arms and said, "Teacher Jiraiya, don't tell me you don't know the essence of our ninja training. While you and Senior Orochimaru are hailed as commoner geniuses, are you truly commoners?"

"Teacher Jiraiya, you yourself possess the innate chakra affinities of Wind, Fire, Earth, Water, Yin, and Yang – six in total. Your chakra is also vast, far more than that of elites from ninja clans. And you've become a Quasi-Kage Level expert before even turning twenty. Is this something a commoner ninja can achieve?"

"Senior Orochimaru is even more exaggerated. He possesses the innate chakra affinities of Wind, Fire, Lightning, Water, Earth, Yin, and Yang – seven in total. And can he, with those snake eyes, be considered a commoner?

"Keep in mind that Senior Tsunade, the granddaughter of the First Hokage, only possesses five innate chakra affinities."

These words plunged Jiraiya into silence once more. He knew his own situation well. Although he was an orphan, he wasn't a true commoner, otherwise, he wouldn't have achieved what he had today.

"Tsunade is quite lucky this time, to have taken in such an excellent disciple!"

At this moment, a magnetic voice echoed, and a handsome young man with long black hair entered the hospital room, carrying a bag of fruit. His golden snake eyes appraised Shimura Kentei with great interest.

"Senior Orochimaru!"

Standing up and nodding in greeting, Shimura Kentei felt a slight apprehension towards this "Snake Uncle."

Although the other party was currently just "Snake Bro," not having degenerated into "Snake Uncle" or ultimately evolved into "Snake Aunt," he already possessed that potential, and precautions had to be taken.

"Orochimaru, can't you stop Tsunade? I thought we were brothers."

Jiraiya, having recovered, cast a resentful glance. After the previous analysis, he was even more satisfied with his disciple.

It was a shame that such an excellent disciple was snatched away by that woman Tsunade.

Ignoring Jiraiya's complaint, Orochimaru placed the fruit on the low table beside the sickbed, his gaze never leaving Shimura Kentei, growing increasingly interested in this junior.

"What do you mean by innate chakra affinities?"

Licking his lips, Orochimaru was quite interested in the explanation he had just heard, especially the new terms mentioned.

Although he had a general idea of what the term meant, he still wanted to hear this junior's explanation.

"This is a classification developed within our Shimura clan. Chakra affinities that ninjas possess from birth are called innate affinities, signifying what they were born with into this world.

Chakra affinities developed through diligent training after birth are called acquired affinities, signifying what they possess after being born into this world."

Shimura Kentei naturally shifted the blame to his own clan. Only in this way could it be rationalized.

After all, even if he said he came up with this classification, others wouldn't believe him!

If they did believe him, it would bring a series of troubles. It was better to blame the clan.

"A perfect description!"

Licking his lips again, Orochimaru's interest grew, but it wasn't directed at Shimura Kentei, but rather at the "Shadow of Shinobi," Danzō Shimura.

The Shimura Clan's foundation was deeper than he had imagined, and that old man must have many good things.

Those were things he needed!

"Stop daydreaming. The First Hokage's power is unrepeatable. It's a miracle if one appears in a thousand years."

Glancing at Jiraiya, Orochimaru offered a reminder before turning to leave.

When Jiraiya was young, he used to brag about the Great Toad Sage's prophecy. Orochimaru didn't believe a single word of that so-called prophecy; only a fool like Jiraiya would believe it so wholeheartedly.

"Teacher Jiraiya, please rest well!"

Shimura Kentei also didn't linger, bidding farewell and leaving the hospital room.

"The seeds of doubt have been sown; now we just wait for them to take root and sprout!"

Walking out of the hospital, Shimura Kentei glanced back at the window of Jiraiya's room. He didn't know when the foreshadowing he had planted this time would take effect, or if it even would.

However, it was just a casually planted foreshadowing. If it worked, great; if not, there was no loss.

"Whether that Great Toad can truly predict the future or is just fooling people will be seen this time!"

A smile appeared on his face, and Shimura Kentei quickly headed towards the Shimura ancestral grounds, preparing for the battle tomorrow.

He didn't want to be beaten up by that woman Tsunade. Moreover, to deal with Tsunade, he had been undergoing targeted training these past few days.

"Are you sure you want Older Sister to go all out?"

Standing with her spear, Shimura Keiko felt her little man seemed a bit overconfident, actually wanting her to go all out against him.

If he were wearing that perverted Battle Suit, she would naturally be helpless. Although she was a Jonin, breaking through that turtle shell wouldn't be easy.

But now, that little man was only holding that greatsword. He was really getting ahead of himself!

Shimura Kentei also seemed to feel it wasn't safe enough, so he turned and put on the inner armor placed on the rack. After all, the sharpness of that Bright Silver Spear was terrifying. If it accidentally took out his "bird's nest," it would be a disaster.

"Let's begin, Sister Keiko!"

After putting on his inner armor, Shimura Kentei signaled for the battle to start.

Without a word, a smile playing on her lips, Shimura Keiko formed hand seals. She first unleashed Wind Release Ninjutsu and Lightning Release Ninjutsu to enhance herself. Instantly, whirlwinds swirled around her, and electric sparks flashed, boosting her speed to the absolute limit.

Her figure flickered, appearing before Shimura Kentei as if she had teleported. The Bright Silver Spear in her hand shot out dozens of cold glints.

Shimura Kentei's reaction was just as swift. He enhanced his reaction speed and strength with Super Speed Technique and Super Strength Technique. Wielding a greatsword of the same 108 jin weight, he rapidly swung it, blocking each of the incoming cold glints.

"Clang, clang, clang..."

Both were employing fast-paced offensive tactics. The frequency of the spear blade and sword body colliding was extremely high, and the dull sounds of metal striking metal continuously echoed.

This high-speed exchange lasted for a full thirty seconds before finally concluding with Shimura Keiko's spear blade at Shimura Kentei's throat.

"He lasted thirty seconds!"

Ignoring the spear blade at his throat, Shimura Kentei was quite surprised by this outcome. He quickly understood what had happened.

He recalled that after updating the data for Keiko's clone, he could only last five seconds. This time, however, both had attacked with full power, yet he managed to last thirty seconds against Keiko's main body – a sixfold difference.

"Does absolute rationality increase combat power by that much?"

Lost in thought, Shimura Kentei felt this was a good path to increasing his strength and decided to research it further.

A clone had no consciousness, essentially being an entity of absolute rationality. Once in combat, it could unleash its power to its absolute limit and never make mistakes, making it perfect.

Keiko's main body, however, couldn't reach that state of absolute rationality. In terms of combat power output, it was far inferior to the absolutely rational clone.

If he could find a way to possess that absolute rationality like the clone, his strength would definitely increase by a notch.

"To last thirty seconds under my hand, you haven't been slacking off these past few years. However, Senior Tsunade's strength far surpasses mine, and the information about your battle suit has already leaked. She will definitely use targeted methods tomorrow."

Standing with her hands behind her back, Shimura Keiko wasn't optimistic about her young man's assessment battle tomorrow. She estimated he would get thrashed.

"That's not necessarily true!"

With a mysterious smile, Shimura Kentei offered no further explanation. He turned and put on the armor from the rack. Once fully dressed, he headed towards the basement, where he would conduct targeted training.

"So mysterious!"

Pouting, Shimura Keiko was very curious about what her young man was tinkering with in the basement but didn't ask further. She returned to studying the cultivation method for the Body Strengthening Technique.

After a week of studying, she had basically mastered the frequency of the Tiger Leopard Thunder Roar for visceral training. With another week, she could transform the frequency changes of the Body Strengthening Technique into the instinct of her own breathing, allowing for continuous training twenty-four hours a day.

The Body Strengthening Technique indeed offered minimal improvement to herself, but with all-day training, the cumulative effect would be quite astonishing.

Not to mention, there were other Body Strengthening Techniques available for cultivation, which could temper and improve the body in all aspects.

The improvement in physical fitness was immeasurable for a ninja like her who specialized in Ninjutsu and Taijutsu.

Meanwhile, in the basement, Shimura Kentei was using a shield to block a massive iron ball weighing over a thousand kilograms, a solid one at that.

The iron ball, suspended by a chain, swung down again. Shimura Kentei met it with his huge, heavy shield, but strangely, no sound was made.

As the shield made contact with the swinging iron ball, Shimura Kentei controlled the shield to move slowly backward, sticking close to the iron ball. Simultaneously, he slightly bent his arms, legs, and spine, like a spring, absorbing the immense force of the iron ball's impact.

After completely dissipating the force, he slowly pushed the iron ball back, minimizing the rigid impact of the force.

Directly confronting external force was the most foolish approach. After all, human bones and joints had limited strength. Repeated violent impacts could easily cause bones to shatter.

This was where his years of diligent practice of Tai Chi Fist came into play. Using the gentle techniques and philosophy of Tai Chi Fist, he continuously diffused the powerful external force and then prepared to counterattack, minimizing the pressure on himself.

If he could master this, he would be able to handle that violent woman Tsunade, unless she resorted to Kage-level strength and disregarded all honor.

"That woman shouldn't be that shameless, right?"

While continuously blocking the iron ball, Shimura Kentei pondered.

Although Tsunade was notoriously lacking in integrity in the original work, especially when evading debts, where she would go to any lengths, even transforming into a little loli to deceive her creditors.

However, the current Tsunade's bust had not yet reached its peak, and she was still just an older young girl. She shouldn't be that lacking in integrity.

Or so he thought.

Just as Shimura Kentei was contemplating Tsunade's integrity, on the other side, at the Senju compound, Tsunade, after hearing the intelligence brought by her uncle Senju Tōsu, decisively headed to the clan's treasure vault, preparing to activate the ultimate ninja tool her great-grandfather had used to counter the Uchiha Clan Fan.

Opening the long-sealed treasure chest and looking at the ultimate ninja tool within, Tsunade laughed, a hearty, unrestrained laugh.

"Hahaha... you little pervert, tomorrow I'm going to beat you into a puppy!"

Senju Nawaki, standing outside the clan's treasure vault, shivered as he heard his older sister's devilishly charming laughter from within.
