Flawless

The first attempt was naturally difficult. Kanna first tried to rely on his own control, imagining his body as a circle, then driving his chakra to circulate in a flow different from his usual habits, but he failed very quickly.

Failure was no matter, however. When beginners use this type of chakra circulation, they do not rely on their own strength to cultivate, but rather borrow from a series of hand seals and body postures.

Just as crouching down lowers one's center of gravity, and starting with the Tiger seal naturally causes a Fire Style technique to condense into a spherical shape, this method also had its own auxiliary seals.

Kanna loosened up his body, then placed his hands in a circle before forming the Tiger-Rat-Rabbit-Monkey seals in sequence. His internal chakra was guided, slowly rising from his abdomen to his throat, pulsing with a restless urge to spit something out.

If Kanna had converted his chakra into water according to the standard Water Style formula at this moment, it would have been a basic Water Style technique. Here, however, he was using the hand seals to facilitate the chakra's flow to his throat.

Kanna then formed the Ox-Boar-Tiger-Rooster-Boar seals. The chakra flowed down from his throat, splitting into two strands that coiled around each other like two dragons fighting for a pearl, beginning to circulate in his abdomen.

This was the differentiation formula for Water Style. Water Style techniques, which often win through sheer volume, are peerless among the five elemental styles in this regard; not only can they split one into two, but many Water Style techniques can even split into three, four, ten, or a hundred.

Next, Kanna completed the hand seals one by one, guiding the chakra to wander through his body. Because it had not been converted into a ninjutsu, there was no loss of energy beyond the portion naturally absorbed by his body, which Kanna's chakra reserves could easily handle.

Of course, this was only the preliminary circulation. Kanna could not yet control the deeper aspects, such as bypassing common meridians and acupoints, avoiding the internal organs, or creating a new chakra condensation point within the body; these were things that could only be achieved after extensive practice.

As one cycle finished, Kanna finally formed the Ram seal. The chakra, now divided into six strands, began to contract toward his heart. Since he had not yet created a new circulatory system, he still needed to return the chakra to his heart for the time being.

However, as Kanna condensed the chakra into a mass and moved it toward his left chest, he suddenly remembered a long-forgotten fact!

His heart was not on the left! He had a right-sided heart, unlike most people!

Whether it was meridians or acupoints, this was fine, as they were things invisible to the naked eye. But the heart was a physical reality. Kanna's chakra had already gathered at his left chest; if he followed the normal procedure, he would have to return to the origin, control the chakra to avoid the Gate of Death, return it to the heart, and restore it to the physical body to complete the cycle. But what was he supposed to do if his heart was on the right?

There were no direct meridians between the left and right chest for Kanna to transport the chakra, and the Third Hokage's circulation formula never mentioned what to do if the heart was in the wrong position. Helpless, Kanna had to release his control over the chakra, letting it dissipate throughout his body. This final step of the cycle failed just like that.

Chakra circulation was inherently delicate; a tiny mistake could lead to the failure of a ninjutsu. The set of techniques the Third Hokage taught Kanna was exceptionally refined and tolerated no errors. Now, Kanna could complete every step, but his heart was in the wrong place!

Of course, theoretically, one could skip the practice steps and set up a new system within the body from the start. But without sufficient understanding of one's own body and enough chakra control, it was easy to cause a physical collapse. How could one expect to fly before learning to walk?

With a splitting headache, Kanna had no choice but to rethink this chakra circulation formula to see if there was another way out.

The practice method was just as Kanna had done, but the next step should be to gradually familiarize oneself with one's body, attempt to connect the chakra flow routes, penetrate the limbs and torso, then completely bypass the internal organ system to build a complex and precise new chakra network, and finally reconnect the abandoned meridians and acupoints, merging all chakra points in the body to turn oneself into a "circle."

It was clear that the "circle" mentioned in this chakra circulation formula was not literal, but a concept. The "circle" represented perfection and flawlessness. Therefore, those who practiced this circulation would eventually have a body that became perfect, flawless, and leak-proof.

The method was right in front of Kanna, and the Third Hokage hadn't hidden the specific auxiliary hand seals or the circulation formula. The problem was that he couldn't even get past the first step. What was he to do?

His first thought was actually to perform surgery.

Isn't it just a right-sided heart? One surgery to transplant the heart back to its original position! I give up, are you happy now?

"Sigh... there are so many ways to refine chakra, so it's understandable why some ninjas have a talent for certain ninjutsu while others can never learn them. It seems it really does have to do with each person's constitution. Is this the reason why Kakashi and Sasuke have the Lightning Style activation constitution?"

It was very likely. One look at Kanna's current frustration was enough to tell. If Kanna had been born with the meridians, acupoints, and internal organs that matched the Mizukage's special circulation, he wouldn't need to set up a new system at all; he could use it immediately. If Naruto's hand meridians and acupoints had been born in a spiral shape, his chakra would naturally condense and swirl into a rotating ball when it surged out, without needing any deliberate control.

In the ninja world, it wasn't unheard of to strengthen one's combat power by modifying the body. Hanzo of the Salamander, known as the "Demigod," implanted the poison sac of a black salamander into his body, and after it gradually fused with his flesh, he gained his own poison-producing and poison-resisting organs. As for Orochimaru, that went without saying; he had "snaked" himself to the point where he was barely human anymore.

The ultimate goal of the Third Hokage's chakra circulation formula was to change the original meridian and acupoint system within the body to create a network best suited for chakra circulation.

However, thinking of this, Kanna seemed to find a clue.

When it came to different systems, he had one inside his body too!

Highland! This thing, whatever it was, could analyze ninjutsu and Bloodline Limits, so it should be able to analyze this circulation formula as well!

Fortunately, this circulation formula wasn't particularly profound; it was just that some of the secrets within it hadn't been discovered by others. Without hesitation, Kanna pulled open his collar, erased the Flying Thunder God formula in a few strokes, carved this circulation formula in its place, and finally poured all his chakra into Highland.

The feeling of using Highland's power was truly different! Kanna felt his chakra not following its usual routes, but instead circling and intersecting, spreading throughout his entire body—permeating his brain, torso, limbs, internal organs, blood vessels, and even every pore and cell. Everything was connected. The junction points were like stars in the sky, evenly distributed throughout Kanna's body, finally connecting into a massive, perfect network.

This method of differentiated control was astonishing! Only after using it did Kanna realize that the highest achievement of this circulation formula was to connect every "point" in the human body. It was as if a martial artist had opened up all their extraordinary meridians and vessels. With the assistance of Highland, Kanna had forcibly turned his physical body into a flawless whole!

"Excellent! It seems the technique on Highland cannot be changed for a while!" Kanna said to himself, filled with excitement. "As long as I persist, with chakra washing over my body every moment, I can grow stronger bit by bit. Eventually, the routes the chakra flows through will be naturally recorded by my body, forming a conditioned reflex and creating a brand-new circulation within me!"

In reality, as long as Kanna used Highland at all times, this circulation could continue. But there were some ninjutsu he simply couldn't perform without Highland, right? For example, the Flying Thunder God or Shinra Tensei, which he still couldn't fully analyze. Therefore, he needed to make his body adapt to this circulatory system as quickly as possible so that Highland could be freed up.

With a chakra network covering his entire body, he wouldn't have to worry about not being able to learn any technique! Aside from those Bloodline ninjutsu that defied all logic, the flow paths of all ninjutsu were within this network!

Five-element chakra! Kanna knew without thinking that if he were to test himself now, the chakra test paper would definitely show signs of all five elements. This was the mystery of the human body!

A step to the heavens! This was truly a step to the heavens. The power of Highland once again exceeded Kanna's imagination, allowing him to reach a level that even the Third Hokage, its developer, had never attained!

Perhaps it wasn't a "perfect body" yet, but if it were called a Flawless True Body, Kanna felt he could definitely live up to the name!

He raised his hand and channeled chakra into a certain network. With a gurgle, a water ball the size of a palm condensed. Then, following Kanna's will, it made various changes; whether flattening into a sheet or condensing into a cube, it was incredibly smooth!

With a flick of his hand, the water ball flew out the window and plastered itself against the wall of the apartment building, spreading into a thin, flat layer. Kanna took a step, jumped high, and his body stuck to the water surface, parallel to the ground. He immediately activated the Water Style: Water Body Flicker, which he had already memorized!

Whoosh! He slid rapidly across the surface of the apartment building, moving up and down. Kanna closed his eyes, spread his arms, and laughed happily.

On the building, the ninjas walking along the walls stopped one after another, looking curiously at Kanna as he darted around on the shifting water surface. Suddenly, a middle-aged ninja cheered: "Good! What a powerful Water Style technique! Come, come, let's have a spar!"

With that, the middle-aged ninja descended from above, throwing a punch straight at him.

Kanna was immersed in a magical state. When the middle-aged ninja's punch came, his body reacted naturally. He stepped forward, lowered his waist, circled his hands inward, then lifted and parried the punch, countering with a finger strike.

Gentle Fist Art: Eight Trigrams Sixty-Four Palms! Meridian-Blocking Strike!

This finger was aimed at the middle-aged ninja's heart meridian, while simultaneously striking the shoulder blades, throat, chin, and all the internal organs. If hit, he would be ready for an emergency trip to the hospital.

The middle-aged ninja was pleasantly surprised rather than alarmed. He formed hand seals, then grabbed with his palm. A water ball enveloped Kanna, and the finger of the Meridian-Blocking Strike poked a clear indentation into the inner surface of the water ball, but that was as far as it went.

A classic ninjutsu of Kirigakure: Water Style: Water Prison Technique, the ultimate technique for trapping and locking down an enemy!

However, just as the middle-aged ninja thought the fight was over and prepared to withdraw, Kanna opened his eyes. The next moment, with a swish, the layer of water under his feet surged out, pounced onto the middle-aged ninja, wrapped around him, and merged, turning into a water ball that trapped him instead.

"Water Prison Technique? No! This is a hollow spherical deformation created by purely controlling the water flow?" The middle-aged ninja was stunned. He waved his hand and said, "I give up, I give up! Impressive! Truly impressive! To have this level of chakra control, to achieve this degree of deformation without hand seals or ninjutsu—at your age, you are simply a genius!"

"Haha!" Kanna laughed freely. Both sides dispelled their ninjutsu and exchanged names.

"Kanna, Genin."

"Shiro Kamimizu, Jonin." Shiro Kamimizu looked at Kanna with a strange expression and said, "What a monster. Just a Genin, yet you have this kind of strength. A genius, a true genius, no worse than Zabuza..."
