Chapter 19: The Thousand-Li Horse, Hyuga Glazed Robe
Hyuga Ningyuan created the Cat Swing as a side project; his real purpose in opening his eyes was to study the principle behind the Byakugan's clairvoyance, then find a way to block it.
Otherwise, living in the Hyuga nest, he couldn't even cultivate immortality.
So, the question was: how to block the Byakugan?
Hyuga Ningyuan discovered that not all objects could be penetrated by the Byakugan. First, bones could obstruct its line of sight.
Second, muscles could too, because when the Byakugan observed muscles, it clearly saw a gradient in the muscle texture, proving that muscles did hinder some of the Byakugan's vision—just not much!
The most effective materials were various metals. For example, the kitchen utensils Hyuga Ningyuan fetched from the kitchen—whether iron, copper, or aluminum—all had some effect.
"This image, this form... why does it look so familiar?" Hyuga Ningyuan stared at the skeletal frames walking back and forth outside, pondering until he finally slapped his palm: "Isn't this just an X-ray?"
X-rays, also known as X-radiation, are electromagnetic waves with extremely high frequency, very short wavelength, and immense energy.
X-rays have penetrating power, but due to differences in density and thickness among human tissues, the degree of absorption varies when X-rays pass through different tissues. After imaging processing, different visuals are obtained.
This bore an extremely high resemblance to the world observed by the Byakugan, leading Hyuga Ningyuan to instinctively wonder: could the Byakugan's vision be a type of X-ray?
Except X-ray imaging requires an emitter and a receiver.
So, the question was: how did the Byakugan accomplish both emission and reception?
"Chakra!" After much thought, Hyuga Ningyuan concluded it could only be due to chakra.
The Byakugan converts chakra into a substance similar to X-rays and emits it. Although these X-rays are extremely similar to natural X-rays, like the fire released by Fire Release or the water by Water Release, they are ultimately products of chakra.
Thus, natural X-rays reflect off metal, but the X-rays created by chakra return spontaneously.
So, the Byakugan is both the emitter and the receiver of X-rays!
Of course, all of the above was Hyuga Ningyuan's speculation. Whether it was true required further verification.
So, the question was: how to verify that the Byakugan's vision is X-rays?
Hyuga Ningyuan mulled it over and found the answer: no need to verify, and no ability to verify!
Chakra, after all, is not a natural substance; it's a force of will.
In fact, with changes in thought and personal will, the Byakugan can see far, far more than X-rays ever could!
You can treat the Byakugan's vision as X-rays, but you can't truly define it as X-rays—that would be self-limiting.
One should set a broader concept than X-rays, such as: electromagnetic waves!
X-rays are just one type of electromagnetic wave, so why not expand the concept to electromagnetic waves?
And from electromagnetic waves, one could naturally expand further—to the four fundamental forces: electromagnetic force!
This wasn't an exaggeration at all. After all, the upgraded Tenseigan could control gravity and repulsion, so what problem was there with the downgraded Byakugan controlling electromagnetic force?
None at all!
"Byakugan = electromagnetic waves, chakra = telekinetic power. The Hyuga Clan can also release chakra from all their body's acupoints, generate massive amounts of chakra in an instant, and even slap away the Ten-Tails' claw with one palm!"
The deeper he delved into the Hyuga, the more he felt this clan seemed... terrifying!
Yes, think about it: the Sage of Six Paths' sons, Indra and Asura, split his bloodline in two, yet that still created the two monstrous clans, the Senju and the Uchiha.
So, the question was: the Hyuga Clan's ancestor was the Sage of Six Paths' brother, Otsutsuki Hamura, and Hamura's bloodline wasn't split among several brothers—it was all passed down to the Hyuga Clan!
Didn't that mean the Hyuga Clan's bloodline rivaled the Uchiha + Senju?
No mistake there. The Uchiha + Senju could only obtain the Rinnegan, while the Hyuga Clan alone could awaken the Tenseigan—wasn't that one clan matching two?
So, with such an incredible bloodline, why was the Hyuga Clan so low-key in Konoha, only playing support in major battles?
"The Hyuga Clan's survival wisdom?" Hyuga Ningyuan pondered and realized that this Caged Bird was actually a good thing.
It did suppress the Hyuga Clan's creativity, but it also genuinely preserved the clan.
If this thing hadn't existed to suppress the Hyuga Clan's creativity and desire for development, then such a monstrous clan would have long been ganged up on by other families!
Who let you be so incredible? The ninja world couldn't allow such an incredible ninja clan to exist!
Not to mention anything else, Black Zetsu couldn't tolerate it!
Under these circumstances, how could the Hyuga Clan have lasted a thousand years?
Setting aside the distant past, the Uzumaki Clan was incredible, right? Massive chakra reserves, self-created sealing jutsu that sealed heaven, earth, and everything, and they even founded their own country.
So, where was the Uzumaki Clan now?
Though it had the ability of a thousand-li horse, if it couldn't eat its fill and lacked strength, its talent wouldn't show outwardly. Even wanting to be equal to an ordinary horse was impossible—how could it be expected to run a thousand li?
The Hyuga Clan was that thousand-li horse that never showed its ability.
But the problem was: a thousand-li horse goes to war and dies in two months, while an ordinary horse lives out its lifespan in the stable.
For an individual, they'd absolutely want to be a thousand-li horse—after all, a man born between heaven and earth, how could he languish under others?
But for a clan, quietly being an ordinary horse and passing the family line down was the greatest wisdom.
So, the Caged Bird was fine, and the Main Family was fine?
Of course not.
Before Hyuga Ningyuan arrived, this system was naturally fine.
But now that Hyuga Ningyuan is here, you're oppressing me!
This system has a problem!
The survival wisdom of the Hyuga Clan was fine, but times have changed, and it's time to change the Hyuga Clan's rules as well.
"Oh right, what was I supposed to be doing?" Ningyuan snapped back to focus. I was supposed to be researching the Secrecy Method.
There are quite a few things that block the Byakugan's vision, with metal plates—preferably lead plates—being the most effective.
But Ningyuan has the Point Allocation System, so he doesn't need to carry weights to train Taijutsu.
Besides, wearing a thick iron plate blocks a huge area of vision. No one was paying attention to you before, but wearing that would just draw eyes.
So, since external objects are out, the only option is the second plan.
Chakra!
The Byakugan can observe chakra, which means chakra can either absorb the Byakugan's vision or block it.
Either way, it can shield the Byakugan's sight.
So, simply covering the area around the dantian with chakra 24/7 would naturally block the Byakugan's vision.
And this behavior wouldn't arouse suspicion, because any mature ninja has Chakra Extraction down to instinct, and the dantian area is always filled with chakra.
Taking it a step further, covering the entire body with chakra to form a Chakra Film would also allow for safe cultivation of the method.
And doing this wouldn't raise suspicion either, because people with abundant chakra do this all the time—covering cells with chakra enhances strength and defense.
When Karin Uzumaki used the Mind's Eye of the Kagura to observe Sasuke, every single cell in his body was filled with chakra.
"My chakra reserves are low, so filling my whole body isn't possible, but forming a film is worth a try!" Without further delay, Hyuga Ningyuan controlled his chakra to burst out from all his pores, then attempted to spread it along his skin to cover his entire body.
"My chakra control is a bit poor!" He didn't know until he tried, but the moment he did, problems surfaced.
Releasing chakra from the pores was easy, but precisely controlling every stream of chakra from each pore required a hundred minds working at once!
Scale it down, scale it down!
"I can release chakra from my left hand and recover it from my right hand, letting it flow through my entire body. Or, I can release chakra from my feet and recover it from the top of my head."
The latter option also allows covering the feet with chakra and walking barefoot, which greatly trains chakra control.
That disciple of Zhu Yuyan did exactly that—by the way, how do you even pronounce those two characters?
Unfortunately, Hyuga Ningyuan is a boy. If a girl walked barefoot, people would call her a barefoot spirit.
But a guy? That'd just be the Barefoot Immortal!
In the Dou Po anime, there was a Dou King who went barefoot. It looked cool and he could tread on air, but paired with bare feet, it always felt off.
In short, bare feet aren't suitable for men.
"No big deal. I'll just cover my shoes with chakra too. From now on, my goal is to walk without picking up dust and step on water without wetting my shoes!"
The ultimate goal: leaving no trace on snow!
"Hmm, when chakra flows through my body, I can also use it to clean off dirt and sweat. But if that's the case, releasing chakra from the soles and inhaling it through the head would be weird. So, I'll switch to releasing from the head and inhaling through the soles."
This way, dirt on the body gets pushed to the ground by the chakra, and since chakra is pure energy, it won't be contaminated by dust, so recycling it carries no psychological burden.
The entire training process not only cleanses the body but also trains chakra control and Telekinetic Power, while concealing the secret of internal qi cultivation.
Because chakra is constantly flowing around the body, it's like having a shield up at all times, capable of defending against sudden attacks.
"Pure and undefiled, neither increasing nor decreasing—I'll call this technique [Glazed Robe]!"
