Of course, he could also employ righteous means, injecting a form of positive energy into the chakra. This would allow practitioners to be influenced by this energy while using their chakra, causing them to become kinder, more righteous, and blindly enthusiastic about everything.
Take Naruto, for example; no matter what wrongdoings an enemy committed, he would forgive them as long as they admitted their mistakes.
He could even forgive Obito, the man who killed his parents, without caring in the slightest about how his parents might have felt.
It was a kindness that bordered on being more beastly than a beast.
Regarding this.
Uchiha Tenshu pondered to himself, certain that the Sage of Six Paths must have tampered with the souls of his two sons.
Otherwise, how could he be so indifferent to his own flesh and blood, leaving them to their own devices?
He himself lived forever in the Pure Land, free from the threat of mortality, while simultaneously controlling the situation across the entire Ninja World.
Yet, the chakra of his two sons reincarnated endlessly, each cycle leading the entire Ninja World into slaughter as they turned against one another.
Could all of this truly be a coincidence?
Most crucially, even the Sage of Six Paths could keep his soul resident in the world, and his brother's soul had also endured for a millennium.
His two sons, whose strength was not much inferior to his own, had never appeared in the original plot from beginning to end.
In reality, this simply made no sense.
Furthermore, there was the hypocrisy of the Sage of Six Paths.
On one hand, he desperately manufactured wars, plunging the Ninja World into endless chaos and slaughter, without ever lifting a finger to stop it.
On the other hand, he spoke incessantly of wanting peace for the Ninja World and encouraging mutual understanding, yet he would deliberately arrange various contingencies to stop anyone who attempted to unify the world, forcing others to "understand" one another.
Was this not self-contradictory?
What was even more baffling was his act of bypassing the elder to favor the younger, arranging for the powerful elder brother to submit to the weaker younger brother. Such an obviously unreasonable practice was undoubtedly a deliberate attempt to incite conflict, sitting on the mountain to watch the tigers fight.
Therefore, after Uchiha Tenshu removed the limiter on his own chakra, he found some answers.
"Perhaps, the Sage of Six Paths did this intentionally."
"After all, he and his brother had usurped the rule of the world from their mother, sealing Kaguya Otsutsuki away, and had lived in constant anxiety ever since, worrying about his own two sons. It is much like the King of Gods in Greek mythology, constantly facing threats from his own offspring."
"One must realize, as a descendant of the Otsutsuki Clan, he knew better than anyone what kind of powerful, astonishing, and terrifying potential one possessed. Thus, in such a situation, to neutralize threats, plan for the future, and prevent his two sons from joining forces against him as he and his brother had done, Hagoromo Otsutsuki did not act directly. Instead, he cleverly turned the two, who should have been united, into bitter enemies. In this way, neither could ever defeat him with their own strength alone."
"Looking at the later results, this was indeed the case! Indra and Ashura, the two sons of the Sage of Six Paths, became total enemies, opposing each other for generations. They engaged in fierce confrontations time and again across the Ninja World, each developing powerful ninja clans and slaughtering one another without end. In these thousand years of warfare, who knows how many souls of powerful individuals were sent to the Sage of Six Paths' Pure Land, and how much chakra was continuously funneled there!"
"Thinking about it this way, this Hagoromo Otsutsuki, the Sage of Six Paths, is truly a devious old fox. I suspect that the concept of life and death was merely a ruse to make his two sons focus more on their struggle; otherwise, if the Sage of Six Paths himself didn't 'die' once, he might have feared his sons would try to seek immortality just as he had."
Uchiha Tenshu could understand the logic; if even their father, the Sage of Six Paths, had died, then the two sons likely wouldn't believe their own lifespans were particularly long. Compared to pursuing a long-term future, they focused more on the impulsive grievances of the present.
Consequently, following the Sage's design, the two brothers, despite possessing powerful bloodlines and innate Otsutsuki talent, fought regardless of the consequences.
Uchiha Tenshu also understood why the Sage of Six Paths did not act directly to kill his two sons.
On one hand, he wanted to control the entire Ninja World by having their bloodlines diluted and passed down throughout the world, ensuring that the ninjas and experts who died were of a higher caliber. On the other hand, because of the example of his mother, Kaguya Otsutsuki, he knew that no matter how powerful one was, if they stood against the entire world, they would eventually be found out and defeated. Thus, he could not openly reveal his evil side; even his righteous side had to depart when the time came, leaving the stage for others to perform.
As for the Sage of Six Paths himself.
He only needed to build the stage from the shadows.
The actors would take the stage themselves!
That was likely how it was!
In short, if Uchiha Tenshu were in Hagoromo Otsutsuki's position, he would certainly carry out all of the aforementioned actions. By then, anyone who practiced the energy of chakra would be unable to escape the fate of being harvested.
And now, the Sage of Six Paths was using a similar method.
It was just at a lower level.
Although the method of planning was the same, the effect was much lower, only capable of collecting the souls of ninjas after they died.
After some speculation, Uchiha Tenshu finally understood: this Hagoromo Otsutsuki was absolutely the mastermind controlling the world of chakra, which was truly chilling.
Especially since the opponent usually hid in the Pure Land without showing his face.
The fact that the chakra of those preserved experts all slept in his Pure Land, waiting for his use, made it clear.
The opponent definitely harbored ill intentions.
And now.
He finally understood where the problem lay regarding the changes in his body just now!
"So, I have had my limiters removed?"
Just as Uchiha Tenshu thought this.
The next moment.
The spirituality of the Fragment of Heavenly Dimension transmitted even more information.
"So that's it. The so-called spread of the Chakra Seed is a signal transmitter and limiter residing within the human body. As long as this signal transmitter exists, the Sage of Six Paths can execute various contingencies. He can also ensure that when a ninja dies, their soul, carrying all their chakra, heads to the existence known as the Pure Land! Not to mention, the limiter on it restricts the nourishment that chakra provides to life! All the life-nourishing effects of the chakra every person cultivates are absorbed by this limiter."
"No wonder this energy called chakra can manipulate natural phenomena like water, fire, wind, and lightning, yet provides no enhancement to the human body. It seems that is indeed the case, because from the very beginning, every ninja has been secretly sabotaged!"
Uchiha Tenshu couldn't help but think of Naruto and Sasuke, who were pulled into the Pure Land by the Sage of Six Paths in the original story. At that time, they were clearly already dead, yet they were still pulled into the Pure Land and directly granted power-ups, entering the Six Paths Level in one go.
The so-called separation of life and death, To him, this was not a difficult problem at all.
Regarding this.
Uchiha Tenshu could not help but sigh to himself; if the Fragment of Heavenly Dimension had not helped him remove it, he feared that even after becoming a Six Paths Level powerhouse in the future, it would have taken a significant amount of time to purge it. If the Sage of Six Paths had struck prematurely, he would have been left either dead or crippled.
"And now, with this restriction resolved, not only do I not have to worry about the hidden trap within the Chakra Seed, but I have effectively transferred ownership of this Chakra Seed into my own hands. Most importantly, now that this restriction is lifted, not only has my entire being become clear, but as I continue to cultivate and grow stronger, my lifespan will far exceed that of an ordinary person!"
