Primordial Scripture

To turn the concept of the Wind God Leg into reality, Uchiha Hara began an in-depth study of how chakra flowed through the meridians in the legs.

Yet this deeper investigation led him to discover a shocking fact—the Ninja World's development and utilization of its own chakra meridian system was outrageously inefficient!

Relying on his powerful spiritual perception and meticulous control over chakra, he "saw" the network of meridians within his body.

It was a vast, intricate system that followed some fundamental principle of heaven and earth: the Twelve Main Meridians, the Eight Extraordinary Meridians, and the seven hundred and twenty acupoints spread throughout them.

It matched the meridian theories of traditional Chinese medicine from his previous life with astonishing precision. Clearly, humanity on this planet possessed physical potential far beyond the Ninja World's current understanding.

After all, this planet was Earth too!

But how did ninjas use this system?

When they refined and used chakra, they only utilized seven meridians, all of them yang meridians, completely ignoring their corresponding yin meridians!

"Only yang, no yin... It's like a circuit with only a positive terminal and no return path. No wonder chakra can't circulate—it can only be released, never reclaimed!" Uchiha Hara found it unbelievable.

It was precisely because yin meridians were absent that chakra could not form a complete cycle within the body. Naturally, it could not gather and be stored in the Dantian, which could serve as an "ocean of energy."

This meant that ninjas essentially refined chakra only when they needed it, unable to accumulate it in the Dantian and nurture it into greater strength like the true qi described in novels from his previous life.

"Right, there's also the Dantian!" Uchiha Hara suddenly came to his senses.

Uchiha Hara had originally thought that people in the Ninja World did not have a Dantian. He had even planned to store his chakra inside the Demon Refining Pot.

But once he sensed it carefully, he realized something was wrong. People in the Ninja World did have a Dantian!

"Of course! Where are a Jinchuriki's tailed beasts sealed? Isn't it in the Dantian—the abdominal sealing space? If it can contain chakra as vast as the Nine-Tails', then the human Dantian's potential must be enormous! Yet the ninjas... were sitting on a mountain of treasure without even knowing it?"

Moreover, running chakra solely through yang meridians for long periods would inevitably create an imbalance of yin and yang, causing excessive yang energy.

That might explain why some ninjas had extreme, irritable personalities and were even prone to hidden bodily injuries. A normal human body should have balanced yin and yang, with the Five-Elements Seal in constant circulation.

"The chakra system was passed down by the Sage of Six Paths... At the level of his Rinnegan, could he really have failed to discover this complete meridian system? Did he do it deliberately, or was it an oversight?" Uchiha Hara's thoughts raced.

If ordinary people had poor aptitude and had therefore only been taught a simplified version, then why had his sons, Indra and Ashura, who possessed extraordinary talent, also continued using this flawed system?

"The only explanation is that he did it on purpose!"

Chakra was an energy of an extremely high level. If it could be paired with a complete meridian circulation technique that allowed people to accumulate, refine, and purify it, its prospects would be limitless!

Tsunade and Uzumaki Mito could prolong their lives and preserve their youth simply by possessing enormous chakra reserves. If chakra could be stored in the Dantian, which held even greater potential, and circulated to nourish the body, then living for several centuries might truly not be a dream!

The Sage of Six Paths had once joined forces with his younger brother to seal their mother, Kaguya. How could he not guard against equally brilliant descendants emerging in later generations and using even greater power to threaten his—or his bloodline's—position?

Restricting the full use of chakra might have been a form of hidden rule.

"Still, his scheme has benefited me now." Uchiha Hara's gaze turned sharp.

Fortunately, the Sage of Six Paths had held something back back then. Otherwise, after transmigrating here, he might have found a world where immortals filled the skies and Six Paths level experts were everywhere.

Now that he had discovered the problem, he naturally would not stand idly by.

He wanted to create a cultivation technique, one that would allow chakra to form a perfect cycle through all Twelve Main Meridians before finally converging in the Dantian for storage!

However, ideals were plump, while reality gave him a brutal blow.

For thousands of years, chakra had only traveled through those seven yang meridians. As a result, those seven meridians were broad and unobstructed, while the other meridians—especially the yin meridians—were like long-neglected country paths, narrow and clogged.

If not for his extraordinary control over chakra, even guiding a single thread of chakra into those narrow meridians would have been difficult.

He did not aim too high and decided to proceed step by step.

He would first focus on opening and establishing a cycle through the Twelve Main Meridians. The more delicate meridians and the Eight Extraordinary Meridians could wait until later.

He named this initial version—the Primordial Scripture.

"Primordial means the beginning of all things, the origin of the first unity. This will be the Ninja World's first true cultivation technique. It deserves this name!"

He devoted himself completely to its deduction, writing and drawing throughout the space, combining it with his own perceptions as he repeatedly simulated chakra's routes of circulation.

At that moment, he desperately wished he possessed a pair of Byakugan that could directly see every minute detail of the meridians.

"It seems obtaining the Byakugan will have to be put on the agenda in the future."

After countless attempts and adjustments, he finally designed the complete circulation route for the first level of the Primordial Scripture:

Starting point: The refined chakra would first flow into the Conception Vessel. Passing through the Chengjiang acupoint—symbolizing the bearing of divine nectar—it would officially enter the first station of the circulation system: the Foot Yangming Stomach Meridian.

Afterward, the chakra would pass through the following meridians in strict sequence:

1. Foot Yangming Stomach Meridian → (connecting at the tip of the toes) → 2. Foot Taiyin Spleen Meridian

2. Foot Taiyin Spleen Meridian → (connecting at the chest and abdomen) → 3. Hand Shaoyin Heart Meridian

3. Hand Shaoyin Heart Meridian → (connecting at the tip of the little finger) → 4. Hand Taiyang Small Intestine Meridian

4. Hand Taiyang Small Intestine Meridian → (connecting at the inner corner of the eye) → 5. Foot Taiyang Bladder Meridian

5. Foot Taiyang Bladder Meridian → (connecting at the tip of the little toe) → 6. Foot Shaoyin Kidney Meridian

6. Foot Shaoyin Kidney Meridian → (connecting at the chest) → 7. Hand Jueyin Pericardium Meridian

7. Hand Jueyin Pericardium Meridian → (connecting at the tip of the ring finger) → 8. Hand Shaoyang Triple Burner Meridian

8. Hand Shaoyang Triple Burner Meridian → (connecting at the outer corner of the eye) → 9. Foot Shaoyang Gallbladder Meridian

9. Foot Shaoyang Gallbladder Meridian → (connecting at the tip of the big toe) → 10. Foot Jueyin Liver Meridian

10. Foot Jueyin Liver Meridian → (connecting at the lungs) → 11. Hand Taiyin Lung Meridian

End point: The chakra would finally flow out through the Shaoshang acupoint of the Hand Taiyin Lung Meridian and return to the Yingxiang acupoint of the Foot Yangming Stomach Meridian, completing one great cycle.

Afterward, this thoroughly tempered chakra would descend along the Conception Vessel and sink into the Dantian's sea of qi for storage.

With the technique newly created, Uchiha Hara immediately began practicing it himself.

The cultivation process was far more difficult than he had imagined.

The ninjas' distorted development over the past thousand years had made the yang meridians as broad as highways and the yin meridians as narrow as goat paths. Yet the technique's route constantly moved from a yang meridian to a yin meridian, then from a yin meridian to a yang meridian.

Every cycle was like speeding down a highway before suddenly making a sharp turn onto a rugged mountain road. It was the ultimate test of chakra control.

Several times, the chakra nearly lost control and rampaged through the narrow yin meridians.

But alongside the pain and danger, miracles were also occurring.

As chakra struggled through one clogged yin meridian after another, he felt as though it was being repeatedly "filtered" and "washed," becoming more condensed and more obedient.

His control over chakra had already been exceptionally strong, yet under this extreme pressure, it improved once more!

Circulating the technique had indeed been difficult at first, but as the chakra became increasingly obedient and the meridians were gradually widened bit by bit, subsequent circulation became smoother as well.

The instant the first thread of chakra completed a full cycle through the Twelve Main Meridians and finally sank into the Dantian—

Uchiha Hara's entire body trembled!

He clearly "saw" that the thread of chakra, originally pale blue, transformed into milky white as it quietly floated within the Dantian!

It was pure and gentle, yet contained a more restrained and powerful force.

The Primordial Scripture had succeeded!

He had successfully made chakra circulate through the Twelve Main Meridians, and he had successfully stored chakra in the Dantian!

Moreover, the chakra's color had changed!!

Uchiha Hara was shaken. "Everyone in the Ninja World has pale-blue chakra. That alone is abnormal! Every person has a different body and a different spirit, so how could different people produce chakra of the exact same color?"

"There is only one explanation for this: contamination by Kaguya's Will, the ancestor of chakra!"

"That is also why, once Kaguya revives, she can so easily seize everyone's chakra!"

"After completing a full circulation, my chakra has been imprinted with my own mark and cleansed of that foreign will. That's why it has become a milky white color unique to me!"

Perhaps only at this moment did this energy truly belong entirely to him.

Because it had been cultivated through the Primordial Scripture, he named it—Primordial True Qi!

The successful creation of this technique brought revolutionary benefits:

1. Storage resolved: Chakra—Primordial True Qi—could finally be stored in the Dantian, resolving the problem of only being able to refine it when needed and never accumulate it.

2. Will cleansing: It had escaped the possible influence of Kaguya's Will, allowing the energy to belong wholly to oneself.

3. Yin-yang balance: Using both yin and yang meridians could improve a ninja's constitution and lead toward true balance of yin and yang.

4. Unlimited potential: Developing the body's entire meridian system meant he could use more intricate and more powerful unique techniques in the future.

5. Foundation remade: His innately powerful physique combined with storable true qi would cause his chakra reserves to undergo explosive growth!

He made a rough estimate. At his current rate of accumulation, perhaps in only a few days, the Primordial True Qi stored in his Dantian would rival that of an ordinary Jonin! If he continued accumulating it, reaching Kage level—or even surpassing Kage level—would not be out of reach!

"If an ordinary person cultivated this technique for fifty years, accumulating true qi day after day, just how terrifying would the amount become? Could quantitative change truly trigger qualitative change and challenge the Six Paths level?" The thought shocked even him.

As he considered once more why the Sage of Six Paths had spread a flawed chakra system, he came to an even deeper conjecture. "Perhaps it wasn't merely because of wariness. The Ōtsutsuki Clan themselves... may not possess meridian systems as complete and exquisite as Earthlings', nor Dantians with such tremendous potential! They are aliens—their bodily structures differ from ours! What they fear is the limitless potential hidden within the seemingly ordinary bodies of Earthlings!"

Naruto Uzumaki had only gained chakra reserves and recovery far beyond ordinary people because the Nine-Tails was sealed in his Dantian—the abdominal seal—and he had unconsciously made use of some of the Dantian's properties.

It was as if this served as indirect proof.

Earth was different. That was the Ōtsutsuki Clan's official assessment. This planet had produced more than one Chakra Fruit, and even the legendary Ōtsutsuki God had chosen to pass away here.

Since Earth was different, could the Earthlings living on this planet truly be ordinary?

The Ōtsutsuki Clan, who had lived for thousands of years, had repeatedly fallen at the hands of Earthlings who were only decades old—or even teenagers.

Looking at it this way, perhaps the Ōtsutsuki bloodline was nothing special. The bloodline of Earthlings was the truly terrifying one!

"This world is far deeper than I imagined. The Ōtsutsuki Clan may not be the peak—perhaps they do not even qualify as the beginning." Uchiha Hara felt the warm thread of milky-white true qi within his Dantian, then looked at the Demon Refining Pot floating in his sea of consciousness. Boundless ambition surged in his heart.

"With the Demon Refining Pot refining all things and the Primordial Scripture laying the foundation for cultivation, perhaps... becoming an immortal in this world may not be impossible after all!"
