The Hokage Family's Washboard

After taking off the heavy battle suit, Shimura Kentei stretched his limbs and walked into the river, taking a deep breath as he gazed at the waterfall ahead.

Bending down, he assumed a sprinter's stance. After a moment of gathering his energy, he suddenly dashed out, running on the water's surface straight towards the waterfall. He then used the rapidly falling water to ascend, quickly reaching the top of the cascade. From there, he stood on the swift-flowing river current at the edge of the waterfall, looking down at Tsunade and the two girls below, their faces filled with shock.

After their initial surprise, the three girls leaped to the bank at the top of the waterfall. They watched Shimura Kentei standing on the fast-moving river water at the waterfall's edge, yet his posture remained perfectly stable.

It was known that due to its proximity to the waterfall, the water flow here was much faster and more difficult to stand on than elsewhere.

Furthermore, the man was currently motionless, relying entirely on chakra to maintain his position. This level of control was truly beyond ordinary imagination.

Kentei wondered how the Shimura Clan had devised such a technique for practicing control.

"What do you two think the chakra spreading through the water beneath my feet looks like?"

Without rushing ashore, Shimura Kentei asked Hyuga Suzune and Uchiha Mikoto, the two young girls.

"Like two fish!"

Staring intently at his feet, one of them, with her Byakugan, responded with sudden realization upon seeing the form of the chakra beneath him.

"That's right, the form of swimming fish. I don't know if you've seen it, but some fish swim upstream during special periods. This chakra control technique originates from that.

Of course, the running start I just did wasn't originally part of it. It's simply because my own chakra reserves are too low, and the resulting swimming fish form wasn't enough to carry me up.

Otherwise, even without moving, these two chakra fish beneath my feet would have been able to bring me up against the waterfall."

After explaining, Shimura Kentei leaped ashore, retracting the chakra that had taken the form of swimming fish back into his body.

He wasn't someone who wasted chakra like Chadunla or Chajinla.

"Ascending the waterfall is the ultimate goal of this stage. You two can start by standing firm in the rapids, condensing your chakra into the form of swimming fish to move upstream.

Once you're proficient, you can find suitable slopes to gradually adapt, and finally achieve the ability to ascend the waterfall against the current while carrying a certain weight. That will mark completion."

After a brief explanation, his gaze fell upon the small hippopotamus Tsunade held in her arms.

The little creature had woken up and was licking around with its tongue, having already entered a horrifyingly dark abyss. Kentei watched, filled with envy, jealousy, and hatred.

Truly worthy of being the Ninja World's number one weapon. His fiancée's situation was at most the Summoner's Rift, while this little one could create an abyss that birthed demons in one's heart. They were on completely different levels.

"You two really are a pair of little perverts!"

Sensing a strange sensation on her chest, Tsunade's shadow clone's pretty face turned dark. She casually flung away the little hippopotamus that was clinging to her chest.

However, her words left the two young girls beside her stunned. They seemed to vaguely understand something, and the flames of gossip began to burn fiercely in their hearts.

"So that's why Master Tsunade always calls that guy a little pervert. There really is something going on!"

Looking as if she had uncovered the truth, Uchiha Mikoto felt she had caught her teacher and that guy in a compromising situation.

As soon as the words left her mouth, Tsunade knew she had spoken out of turn. Especially after seeing the expressions of her two female disciples beside her, her pretty face darkened even further.

She shot a hateful glare at Kentei, made a hand seal, and slammed her hand down on the ground.

"Earth Release: Earth Flow Wall!"

A slope suddenly rose from below the waterfall, extending hundreds of meters and forming a downward-curving arc.

The turbulent water of the waterfall flowed rapidly through the wide groove in the middle of the slope, creating a dedicated area for practicing water-walking techniques.

"Sigh! You're training, but do you have to ruin a scenic spot?"

Holding his little hippopotamus, Shimura Kentei sighed as he saw the beautiful waterfall scenery destroyed.

Ninjas really did limit their options, only knowing how to destroy and not how to build.

Ignoring him, Tsunade's shadow clone leaped to the bottom of the slope, attempting to practice this new water-walking technique.

The two young girls also understood the convenience of such a training ground and quickly followed.

"Stop licking, I'll feed you milk now!"

Glancing at the small hippopotamus licking around in his palm, Shimura Kentei returned to where his battle suit had been, put it on, and picked up the milk bottle.

"Dazui, open wide, it's time for milk!"

He smiled and brought the nipple of the milk bottle closer, watching the little creature greedily drink the milk. Shimura Kentei held great hopes for it, even naming it Shimura Dazui.

"The C-Rank Body Strengthening Secret Technique isn't urgent for now. Besides, that thing would probably require a large amount of chakra to cultivate. Even if I created it immediately, with my current chakra reserves, it's unlikely I could train it.

It would be better to focus on developing the Absolute Rationality Mode first."

While feeding the little Shimura Dazui, Kentei pondered his future training plans.

He had previously read the scrolls on the first floor of the Senju secret archives, especially the training notes of past Senju ancestors. Although most of them only contained scattered remarks regarding the Senju Clan's body-strengthening secret techniques, they had been very inspiring to him.

In addition, the inherited secret techniques he had traded with other ninja clans for using the complete Body Strengthening Secret Technique also contained many useful insights. Especially the batch his father had obtained, which were full of valuable information.

As long as he thoroughly understood these and went through repeated attempts, he could create a C-Rank Body Strengthening Secret Technique.

However, his low chakra reserves were a major drawback. Even if he created it, it would be difficult to cultivate, making it less meaningful.

In comparison, achieving Sage Talent's Sage Mode first was a more stable and effective approach.

Once the little creature in his arms was full, Shimura Kentei found a sunny spot, sat down cross-legged, and entered the Black Cauldron Space to continue creating the brain-death... no, the Absolute Rationality Mode.

This was a project of considerable scale. Fortunately, through various attempts, he was gaining a deeper understanding of the functions of the thirty-six acupoints in the brain, allowing him to gradually narrow down the range of his experiments, forming a virtuous cycle.

He estimated that it would take at most three months to successfully devise the secret method for activating the brain acupoint circulation for Absolute Rationality Mode.

Shimura Kentei's squad was training and improving themselves in the Death Forest, yet a craze was gradually emerging in Konohagakure, a craze ignited by Shimura Kentei.

In a tavern, two drinking buddies were conversing in hushed tones.

"How far have you read in Ninpō Sōkyū?"

"I just got to where Sarutobi Hi no En attacked the prestigious Shimura family and sought out Shimura Yanran to fulfill a three-year pact. That Flame Splitting Wave Staff Nintaijutsu was incredibly cool, and so was the Buddha's Wrath Fire Lotus."

"Then you better read faster, the later parts are even more exciting. Sarutobi Hi no En even conquered the White Snake Sage from Ryūchi Cave. You can't imagine how thrilling those beautiful snake women are.

I saw an illustration of the White Snake Sage, and she was so cold, alluring, and imposing. It made me shamefully hard!"

"What? Sarutobi Hi no En didn't even spare the snakes from Ryūchi Cave?"

"You know Master Yunzhongniao's style, right? There have always been tons of cross-species romance plots in his books. What's so surprising about it?

Besides, the White Snake Sage has three forms: snake form, human body with a snake tail, and the complete human form. It doesn't hinder communication."

"You said you saw an illustration of the White Snake Sage earlier? Give me a copy, I'll pay sixty thousand Ryo for it!"

"Deal. Oh, and I also have an illustration of Shimura Yanran and Shimura Yun. Do you want it?"

"Give me one of each!"

The two men secretly completed a shady transaction. Similar scenes were happening all over the streets and alleys of Konohagakure, and even some women were participating.

There was no other way; the works of Master Yunzhongniao were just that amazing.

Even some Jonin and Kage Level experts had bought a complete set to study at home, such as a certain White Fang.

"The idea behind Three Thousand Lightning Movements is good; it can deepen the practice of the Body Flicker Technique. The concept of Three Thousand Lightning Illusory Body could be applied to Lightning Release Shadow Clones."

Inside the Hatake Clan compound, the current head, Kagami Uchiha, was diligently studying the book in his hands, drawing considerable inspiration from it.

He was also a fan of Master Yunzhongniao's works, though not in that way. He purely valued the techniques and methods described in the books to gain inspiration.

For instance, the Three Thousand Lightning Movements and Three Thousand Lightning Illusory Body from this book, Ninpō Sōkyū, were quite good and provided him with significant inspiration. The sixty thousand Ryo was well spent!

Meanwhile, in the Hokage's office, after finishing a day's work, Sarutobi Hiruzen glanced around, then made a series of complex hand seals. He unsealed the drawer of his desk and took out a beautifully bound booklet, its cover emblazoned with the four golden characters "Ninpō Sōkyū."

The characters looked like flames, as if about to ignite, and were incredibly cool.

"I wonder if I will end up with that Shimura Yanran. Judging by the current plot, that girl seems to have taken an interest in me.

Even though there was the humiliation of the broken engagement, she looks really beautiful in the illustrations. It's worth it!"

Sarutobi Hiruzen murmured softly, his heart filled with anticipation as he carefully opened the book in his hands.

He had bought this first edition of Ninpō Sōkyū long ago, but as the Hokage, his free time was very limited. Moreover, he didn't dare to take it home to read, for fear his wife, Sarutobi Biwako, would find out. That would be trouble.

Having him kneel on a washboard would be the least of his worries. If she burned this set of Ninpō Sōkyū, he would be heartbroken.

Therefore, he could only keep it sealed in the Hokage's office, having personally applied a seal with defensive power comparable to the Scroll of Seals.

He eagerly turned to the page he had last read and began to study it meticulously, word by word, analyzing each character. He lingered the longest on pages with illustrations, often displaying a lecherous smile.

In this way, reading this book, a proper activity that could cultivate one's character and cleanse the soul, replaced his usual work of using the Telephoto Lens Jutsu to monitor and guard the various bathhouses.

"Bang!"

Just as he reached an exciting part, the office door was suddenly kicked open, and a young man walked in. This immediately deflated the excited Sarutobi Hiruzen, almost leaving him with psychological trauma.

"Dad, Mom wants you to go back right now!"

Leaving behind those words, the young man turned and left, decisive and without any hesitation.

"This brat!"

Sarutobi Hiruzen cursed under his breath, reluctantly closed the book and put it back in the drawer, resealing it. He then tidied his clothes and headed back to the family home.

The Sarutobi family home was not far from the Hokage building, and he returned home in a short time. He found his wife kneeling in the room.

Unsure of what had happened, Sarutobi Hiruzen was about to kneel in front of her to ask when a wooden board suddenly flew towards him, landing precisely below his knees.

He looked closely and saw it was a washboard, a brand new one at that, with sharp edges.

"Biwako..."

Seeing the washboard with its sharp edges, Sarutobi Hiruzen's heart trembled. He looked at his wife in confusion, not understanding what was going on. But as soon as he opened his mouth, he was coldly interrupted by Sarutobi Biwako.

"Kneel!"

She commanded coldly. The icy look made Sarutobi Hiruzen tremble. Instinctively, he bent his knees and knelt. His knees landed on the sharp-edged washboard, causing him to wince in pain. He was filled with hatred.

Which bastard invented such a new use for a washboard?
