"Just a few students from the Ninja Academy can provide such an enormous amount of chakra?"
Looking at Namikawa Yū before her, confusion showed in Kaguya's eyes.
She had once been taken by Namikawa Yū to see those so-called students of the Ninja Academy.
Those students were descendants of the Natives. Because the Chakra Seeds had spread, they now possessed a small amount of chakra within their bodies, but neither its quality nor quantity was worth mentioning.
In the eyes of Otsutsuki Kaguya, the Progenitor of Chakra, they were no different from ordinary ants.
Yet these ordinary ants could actually gather such an enormous amount of chakra?
Kaguya instinctively found it unbelievable.
"Sand may be insignificant, but once it gathers together, it becomes a desert."
Namikawa Yū explained, "Although one person can refine only a small amount of chakra, once there are enough people, the situation changes."
How many students were gathered in the Chakra Schools across the various regions now?
Ordinary people were unclear about the number, but Namikawa Yū knew it very well.
There were at least two million of them.
With such a huge number, even if each person provided only a tiny amount of chakra, the amount they could gather would still be immense.
What was more, Namikawa Yū had specifically arranged many things to collect chakra more efficiently.
For example, every school had been equipped with a Chakra Collector made from crystals formed by the power of the God Tree.
Another example was the Chakra Refinement Class he had specially added to the school curriculum. Every student had to inject the chakra they refined each day into the God Tree Crystal, ensuring a stable collection.
After such a long time, it would have been strange if the amount of chakra collected were not substantial.
"Will there be this much chakra every year from now on?"
As she listened to Namikawa Yū's explanation, Otsutsuki Kaguya's eyes gradually lit up.
She looked at Namikawa Yū before her and could not help asking.
"Of course not."
Meeting her gaze, Namikawa Yū shook his head.
Just as disappointment arose in Kaguya's heart, he continued, "Every year, there will be even more than this."
Once the Chakra School system was established, it would only become smoother and more efficient, until it reached a certain limit.
As the education system improved, more children would enroll each year and join the ranks of the chakra-refining army.
And all of them were living sources of chakra.
"Every year, there will be even more than this?"
Looking at the Chakra Crystals before her, Otsutsuki Kaguya's breathing quickened.
The chakra contained within these Chakra Crystals was already a considerable figure to her.
If even more chakra could be used each year, then perhaps it would not take long for the God Tree to truly produce a second fruit.
No—at this rate, it might produce more than one. Two or even three fruits were possible.
"Why had I never thought of such a simple method before?"
She could not help pondering this.
"It isn't that simple."
Before her, Namikawa Yū shook his head.
What he had done might look simple, but it had been anything but easy.
Establishing a complete education system for everyone sounded simple, but even in the era of his previous life, it had taken many years before such a thing could finally be achieved.
Without sufficient productivity, there would be no way to support enough people who were free from production work, and children could not possibly attend school.
Without a governing system with sufficient authority, a complete education system likewise could not be established, or at least could not cover enough people.
To reach his current stage, Namikawa Yū had spent nearly twenty years, even with the assistance of chakra, a power beyond the ordinary.
And that was with him following the correct path, facing no outside interference, and receiving the full assistance of Kaguya, the Progenitor of Chakra.
Otherwise, it would have been even more troublesome.
"Cough... cough..."
Just as Namikawa Yū was about to say something, he was suddenly interrupted by a fit of coughing.
His face was pale, and he looked somewhat weak.
"Yū."
Kaguya stepped forward and injected her chakra into Namikawa Yū's body, worry showing in her eyes.
As time passed, Namikawa Yū had gradually grown older.
By calculation, he was already thirty years old.
At that age, he should still have been in his prime, at the height of his strength.
Yet Namikawa Yū's body appeared somewhat frail.
He had carefully examined the matter and found that it seemed to be due to an innate condition.
Otsutsuki Kaguya was deeply worried about Namikawa Yū's physical condition.
The Otsutsuki Clan naturally had extremely long lifespans, far longer than those of mortal races.
After consuming the Chakra Fruit, Kaguya's constitution and bloodline had undergone an even greater sublimation, bringing her close to an immortal body.
She would no longer die of old age.
But Namikawa Yū was still only a mortal.
He would grow old, and one day, he would die.
Although Kaguya's chakra could nourish him and appropriately delay this process, it was still only a matter of time.
To prolong Namikawa Yū's life, Kaguya had also offered her own proposal.
She could plant her own Karma within Namikawa Yū's body, helping his body complete its transformation.
Karma was a unique method mastered by the Otsutsuki Clan.
It could back up the data of an Otsutsuki body and transfer it into another person's body.
Once Karma was implanted, the recipient would gradually transform into a member of the Otsutsuki Clan, until they were completely replaced by one.
After Otsutsuki Kaguya's true body fell, the reason she had been able to be reborn through a clone was precisely this ability of Karma.
It sounded somewhat similar to body possession.
Under normal circumstances, having Karma planted within them was not a good thing for an ordinary person.
But if it could be actively controlled, that would be another matter.
The situation before them was one such example.
Otsutsuki Kaguya could plant her own Karma within Namikawa Yū's body and allow it to transform toward an Otsutsuki body.
As a backup, Karma would only be activated after Otsutsuki Kaguya's true body died.
Moreover, Kaguya could control the process herself.
In theory, this method could allow Namikawa Yū to obtain part of the Otsutsuki Clan's power without greatly affecting him.
Of course, even so, it could only greatly extend his lifespan. Sooner or later, he would still die.
But that did not matter.
As long as he could consume the Chakra Fruit before dying of old age, he could, like Otsutsuki Kaguya before him, awaken directly from a defective Otsutsuki Body and become an immortal life-form.
Once they reached that point, they could remain together for a long time without worrying about their lifespans.
Regarding this proposal, Namikawa Yū pondered for a moment before choosing to agree.
To him, this proposal had few disadvantages.
