Ron had always harbored doubts about Natural Energy and the role souls played in it. The existence of the Pure Land in the Naruto world intrigued him, especially since, as far as he knew, only ninjas could enter it.
He speculated that the Pure Land was likely created by the Sage of Six Paths. This thought led him to question how Natural Chakra could be harnessed through a deeper understanding of chakra's nature transformation. He began to suspect that souls retained chakra and could exist because it was sustained by chakra and the albeit indirect Natural Energy.
The fact that souls could possess unlimited chakra raised further questions. Ron reasoned that while living ninjas extracted chakra and used it, causing it to dissipate naturally and from using ninjutsu, this energy should ideally return to nature, contributing to the growth of Natural Energy.
However, this didn't seem to be the case chakra, when expended through unmarked jutsu, simply dissipated at a way faster rate, than marked ninjutsu, despite the user having immense control over it.
This led him to a theory, instead of dispersing into nature, chakra might be drawn elsewhere. He speculated that the "chakra mark" inherited by all ninjas acted as an instruction, redirecting dissipated chakra to the Pure Land the Sage of Six Paths' domain.
If true, this could be a mechanism through which chakra was continuously extracted from ninjas, while also potentially enabling the absorption of trace amounts of Natural Energy. Furthermore, Ron theorized that ninjas were never originally meant to use sealed ninjutsu. Although Indra, the ancestor of the Uchiha Clan, was said to have created seals, it was likely the Sage of Six Paths who simplified their use.
Mastering chakra manipulation without seals would have been far more time-consuming, so the Sage may have introduced seals as a fundamental system a rudimentary program to help ninjas control chakra more efficiently. This system could have also been linked to the chakra imprint, also ensuring that the dissipated chakra was directed to the Pure Land after its release.
Ron had already identified the chakra imprint and destroyed his own, but he still needed to confirm his theories about chakra dissipation. His father, possessing a high-quality soul like his own though perhaps less versatile should be capable of releasing chakra outside his body without seals and without it dissipating.
Now, all that remained was for Ron to release his own chakra and observe the results. If his theory was correct, he would then remove the chakra mark from his father and see if he could do the same.
Ron was cautious about removing the chakra mark from others. While it may have been modified by the Sage of Six Paths, its origin is undoubtedly traced back to the Divine Tree and the Ōtsutsuki. Moreover, if the Sage's intentions were entirely malicious, he should have ensured that no one could interfere with the Pure Land, meaning techniques like Orochimaru's Impure World Reincarnation should have been impossible to use. Pure Land was probably a security measure against the Otsutsuki clan.
Even if the Sage of Six Paths had intended to control all ninjas through this mark, it would have been impossible for a living being to suppress everyone without going mad. That was why the Divine Tree was necessary to cast Infinite Tsukuyomi. Rather than a direct means of control, the chakra mark was likely a tool primarily designed to redirect chakra and regulate ninjutsu, making it more manageable through specific rules or keys; the seals.
Ron gathered his thoughts and looked at his father. "Father, I need to test something, and I require your cooperation. For now, do not extract your chakra. Instead, spend as much as you can lower it to the minimum."
The Third Raikage and Ay exchanged bewildered looks but trusted Ron. If needed, chakra could always be extracted again. For now, his father only had to deplete his current reserves.
Ron turned to Bee and Ay. "Stay alert, just as a precaution. I'll move a little farther away and launch a few ninjutsu. Ay, inform the ANBU and tell them to keep their distance just guard the perimeter and don't be alarmed by what happens."
The Third Raikage wasn't concerned about his safety within his own home, especially with Ay and Bee present. More importantly, it was best if the ANBU weren't privy to the coming discussion. Who knew what Ron might reveal? It would be troublesome if they intervened after hearing the ninjutsu. Given that others lived nearby, he made the necessary arrangements.
Then, he moved a short distance away, activated his Lightning Chakra Mode, and began launching various ninjutsu into the sky.
Soon, the Third Raikage returned, and everyone turned to Ron, waiting for his words. Ron nodded and said, "Father, you once said that chakra easily dissipates once it loses direct connection to the body, which is why unsealed ninjutsu is even more difficult. Can you gather some chakra, concentrate it, and try to throw it as far as possible?"
The Third Raikage did as instructed. As soon as the concentrated mass of chakra traveled more than ten feet, it rapidly dissipated. Ron observed carefully, noting that while the chakra initially held together maintained by the caster's spiritual intent as chakra is a mixture of spiritual and physical energy, but there was also an external factor destabilizing it.
Likely, this was a pull or attraction from the Pure Land. Normally, ninjas could control their chakra well, but once it left the body, the chakra imprint's hidden instructions caused it to break apart.
Next, Ron gathered his own chakra and threw it outward. This time, as it moved, it dissipated more slowly, traveled farther, and remained significantly more stable. He could clearly feel the difference there was no external agitation causing it to break down prematurely. He was certain this was due to the absence of the chakra imprint.
Now, he only needed to confirm that his father could achieve the same result once freed from the imprint.
