Having water in his brain—or rather, having an overactive imagination—had its advantages.
His knowledge ran deep and his horizons were broad, so he had different ideas about how to wield power. If even one or two of them worked, he would benefit immensely.
But breaking through from one power system to another wasn't easy.
Completely breaking the dimensional barrier was unrealistic. All he could do was learn from each and combine them.
Recently, he had stepped up his Body Techniques training. While continuing to strengthen Iron Body, he had also begun practicing Shave.
Compared to Iron Body, Shave was relatively easy to learn once his body had reached a certain level of conditioning.
A few months ago, making him stomp the ground more than ten times in 0.6 seconds would have been utterly impossible. Now, with his Iron Body training bearing fruit, he could just barely manage it.
Of course, barely managing it didn't mean he could really do it reliably.
He was still a long way from mastering it. At his previous pace, completing the training within a year or two had been almost impossible.
Then, after he got information on chakra bursts while researching the Strength Enhancement Technique, and trained in the Body Flicker Technique with Fushan, his Shave training made unexpected progress.
He actually succeeded.
Chakra burst techniques
Body Flicker Technique
The two were unexpectedly compatible with Shave. By using chakra bursts, he increased the number of times he could stomp the ground in 0.6 seconds to more than twenty. The secret Body Flicker technique from the Uchiha Clan that Fushan had taught him also combined perfectly with Shave.
The Body Flicker Technique in the Ninja World wasn't a specific ninjutsu. It was a general term for all ninjutsu and Body Techniques that enabled high-speed movement.
Every clan and village had its own unique inherited techniques, and the Uchiha Clan was no exception.
Come to think of it, the Shave Suifeng was studying now counted as a kind of Body Flicker Technique. But unlike other Body Flicker techniques, it wasn't a standalone Body Technique or ninjutsu. It was a perfect combination of the two, more like a Nintaijutsu. Once mastered, it would be incredibly effective, with limitless potential.
But he faced another problem: reaction speed.
This was a problem every high-speed ninja had to face. Without sufficient reflexes, high-speed movement was out of the question.
His reaction speed wasn't terrible, but it wasn't exceptional either. The Shave he had successfully developed—the technique he now called Flash Step—was extremely fast. It might even become a terrifying Body Flicker Technique in the future. He was having trouble keeping up with it.
Now, improving his reaction speed had made it onto his list.
How could he improve his reaction speed?
Lightning Release stimulation.
The Cloud Village's Lightning Release Chakra Mode was famous for a reason.
Suifeng's chakra also had a Lightning Release affinity; he just hadn't developed it.
Come on, he'd only been in this world for three months. How could he have all the time in the world to become a jack-of-all-trades? He didn't have a Hyperbolic Time Chamber.
Still, he really didn't want to mess around with things like using Lightning Release to stimulate his cells.
It looked effective, and it seemed like the cells could adapt and recover on their own.
Come on, cells had a limited lifespan. Doing all that to them would shorten his life. He didn't want to die young.
What? You're telling me to transplant First Hokage Cells?
How did you know transplanting First Hokage Cells would make him live longer? The man himself had died young!
"Let my reaction speed improve gradually. Flash Step is already good enough for me to use. As long as I don't run into a monster like the Fourth Hokage, I can handle myself. Oh, right, Shisui became famous during the Third Great Ninja War and earned the name Body Flicker Shisui. Well, sorry about that—I'm taking the nickname 'Body Flicker'!"
His success with Shave gave him confidence that his Body Flicker Technique would never fall short of Shisui's in the future!
He had gained another trump card to save his life.
But it still wasn't enough. To get Obito's eyes during the Third Great Ninja War, he'd have to face Zetsu and Madara!
"I've already seen how the Zanpakuto enhances Kekkei Genkai. The power of Lava Release keeps increasing, but I'm too young and short on chakra. I can't use Lava Release very many times. Chakra, chakra—it all comes down to chakra!"
His age put him at a disadvantage, and the idea of increasing his chakra reserves had been on his mind constantly. When conventional methods wouldn't work, he'd even tried unorthodox ones—or rather, methods from another dimension: Nen.
What was Nen?
At first, he'd thought it was similar to chakra. But after studying it, he'd discovered that the two systems were completely different.
In the world of Hunter x Hunter, Nen was the ability to control life energy—to freely manipulate the life energy, or aura, released from one's body.
In that world, everyone constantly emitted life energy. Nen was the technique of gathering and controlling that energy. In other words, everyone in that world—even every living creature—was leaking energy.
But people in this world didn't leak energy!
To make sure, Suifeng had even gone out of his way to learn Sensory Ninjutsu. Every night, he sensed his own energy, and reached the conclusion stated above: people in this world didn't leak energy!
If they didn't leak energy, then there was no life energy to gather and control. A ninja's life energy had already become one with their chakra. It didn't leak.
So at first, Suifeng had been disappointed.
But after meeting the big-breasted Princess Tsunade at the hospital that day, he suddenly realized he might have taken his thinking down the wrong path.
That was right. The creatures in this world didn't leak energy, but chakra could still be left over!
People just didn't pay attention to that excess, and didn't know how to use it.
Princess Tsunade's Yin Seal was the best-known method, and the most perfect one. But Suifeng had already flirted with Princess Tsunade once, and he didn't want to try a second time. She'd really beat him to death.
There was no way he could learn the Yin Seal, but that was fine. Since there was excess chakra, couldn't he handle it using Nen techniques?
It seemed possible.
Using Nen training and techniques to control excess chakra had been on his mind ever since he met the big-breasted lady. He had tried it a few times. After several failed attempts, he had roughly found a path. Now he just needed to confirm whether it would work.
First, he needed to figure out what excess chakra was.
Chakra wasn't like internal energy. Although it also traveled through the body's pathways, ninjas didn't have a dantian. Ninjas kept the chakra they refined inside their bodies—or, more precisely, stored it in every cell, releasing it through ninjutsu when needed. (Note)
Everyone's cells had different capacities. The Uzumaki Clan had an abundance of chakra, while ordinary people might not be able to refine any at all, let alone store it.
But cells were still cells. Even big-breasted cells had their limits.
Many ninjas refined more chakra than their cells could hold. A cell was like a bucket: if it could only hold ten pounds of chakra, but I could refine twelve pounds while training each day, the remaining two pounds were excess.
Everyone dealt with this excess differently. In truth, there wasn't much choice. Apart from Princess Tsunade, who had the Yin Seal, everyone else used chakra to temper themselves. As they improved their physical capabilities, they also increased their bodies' capacity. Put simply, they gradually expanded the capacity of their body—the "bucket"—through training, from ten pounds to twelve.
The Yin Seal did the opposite: it stored all the excess. If one bucket wasn't enough, she'd use another.
Why did Tsunade need such a long time to recover every time she used up the Yin Seal? Because she herself was a big-breasted lady, with Senju and Uzumaki Clan blood. Her cells were big-breasted too, so they could store an astonishing amount of chakra. Try it with someone else, and they might not need nearly as long to recover.
Suifeng had excess chakra too. Whenever he refined chakra, he could feel his body reaching its limit, and he stopped once he hit it. But that was the limit of his capacity, not his chakra. He could refine more, but there was nowhere to put it, so it could only dissipate.
That's right, dissipate!!
Wasn't that just leaking energy?!
