"I've named this Breathing Style Immortal Breathing."
Sarutobi Hiruzen said,
"Immortal..."
Tsugikuni Yoriichi paused in surprise, then nodded.
"A Breathing Style that can let someone cultivate into an immortal being really does sound more like the legendary methods for cultivating to become an immortal."
"But the appearance of something like this in the world is still too dangerous."
"Neither demons nor Breathing Styles are really things that should exist."
Tsugikuni Yoriichi couldn't help sighing.
Sarutobi Hiruzen fell silent at his words. Everyone had different values.
Although the Immortal Breathing Style Tsugikuni Yoriichi had invented was, in some respects, even more powerful than Sun Breathing,
for most people, immortality was naturally worth more than anything else.
But Tsugikuni Yoriichi was a thoroughgoing historical naturalist,
who believed that the tide of history would sweep everything away. Demons and the Demon Slayer Corps were all just drops in the ocean.
And in Tsugikuni Yoriichi's view, demons and Breathing Styles, which did not belong in the normal course of history, were nothing special and perhaps should not even exist.
Sarutobi Hiruzen neither agreed nor disagreed. Every world had its own unique laws of operation, whether it was extraordinary or technological.
But from the perspective of personal gain, if the opportunity presented itself, Sarutobi Hiruzen wouldn't mind transforming this world into one with supernatural powers.
The Space-Time Source Energy he gained that way would undoubtedly be immense.
"By the way, you came to see me..."
"Has something happened with the Demon Slayer Corps?"
Tsugikuni Yoriichi had come to visit him in person, so there had to be a reason.
At his words, Tsugikuni Yoriichi nodded.
"Thanks to the weapons containing the sun's power that you provided, Lord Sarutobi,"
"the Demon Slayer Corps is now killing demons several times more efficiently."
"But some swordsmen still die on the path of slaying demons..."
A trace of sorrow crossed Tsugikuni Yoriichi's face.
"In some areas where demons have appeared, many of the swordsmen we sent there have died."
"So Master Ubuyashiki hopes that you and I will go there together..."
"To see whether the Demon King has been spotted nearby."
Sarutobi Hiruzen nodded at his words.
Although he thought it unlikely that the Demon King would show up...
Given Kibutsuji Muzan's personality, once he learned that the Demon Slayer Corps had acquired the ability to kill demons, he would surely lie low for a while.
Only after he had figured out that those people in the Demon Slayer Corps couldn't do anything to him would he come out and run rampant again.
Until he met the heaven-sent hero, after which Muzan never smiled again.
"Then let's set out in a few days."
Sarutobi Hiruzen didn't refuse.
He still needed more specimens for his research into the Perfect Being.
Those powerful demons who had reached the level of the Upper Moons were the best specimens.
"I still need to make some preparations."
After Tsugikuni Yoriichi left,
Sarutobi Hiruzen called Masahiro in.
"Have a seat."
Sarutobi Hiruzen gestured for Masahiro to sit down.
Masahiro looked confused, but obediently took a seat.
Then Sarutobi Hiruzen held out his hand, palm up. Flames of different colors, made of Chakra, ignited on each of his fingers.
Though I can't match the Sage of Six Paths' ability to sow Chakra Seeds throughout the world...
fortunately, as the Professor of Ninjutsu...
I've mastered the nature transformations of all five Chakra natures, as well as Yin-Yang Release.
Sarutobi Hiruzen smiled faintly.
The so-called Truth-Seeking Orbs and Yin-Yang Release techniques...
are the pinnacle of the nature transformations of all seven types.
But even though the Third Hokage, who has no Otsutsuki blood, has mastered every nature transformation...
he still can't reach the realm of Yin-Yang Release.
In other words, the essence of the Naruto world was that bloodline determined everything. Without enough Otsutsuki blood, ordinary ninja could never reach the level of Yin-Yang Release, no matter how hard they worked.
But for the Senju and Uchiha, who possessed Otsutsuki blood, reaching the pinnacle of Yang Release and Yin Release was much easier.
Still...
with the ability to use all seven nature transformations, condensing a Chakra Seed...
isn't all that difficult...
While in the Demon Slayer World, Sarutobi Hiruzen had taken the time to develop this ability to plant Chakra.
It could grant Chakra abilities to humans who had none.
Then the five Chakra nature transformations in Sarutobi Hiruzen's hand, along with the properties of Yin Release and Yang Release, slowly merged.
A round seed surrounded by a hazy black aura appeared in Sarutobi Hiruzen's hand.
Without hesitation, Sarutobi Hiruzen pressed it against Masahiro's chest, planting the Chakra Seed inside him.
"How does it feel?"
Sarutobi Hiruzen asked.
Masahiro looked excited. He immediately realized that Sarutobi Hiruzen was imparting some kind of power or magical ability to him.
"I feel a power flowing inside me."
Masahiro spoke with a hint of wonder.
"And I think I can control it."
Sarutobi Hiruzen nodded, then explained to Masahiro how to refine Chakra.
The method was actually extremely simple. Basically, one focused the mind and drew on the body's cellular energy and spiritual energy, combining them to form Chakra.
Of course, if someone without Chakra potential tried this method, they would do little more than fall asleep. Their body wouldn't change at all, let alone produce Chakra.
Masahiro clearly had the necessary potential now. After just a few dozen seconds, he easily formed his first wisp of Chakra.
"Not bad."
Sarutobi Hiruzen nodded, satisfied.
Of course, he wasn't satisfied with Masahiro's potential as a ninja. Rather, by spreading the Chakra Seed, Sarutobi Hiruzen had brought about a tangible change in this world.
Host: Sarutobi Hiruzen, Current World: Two-Star World—Unnamed... Space-Time Source Energy: 1032 World Mark: Four-Star World—Naruto,
Sarutobi Hiruzen looked at the words "Unnamed." With a thought, he changed them to "Demon Slayer."
Sarutobi Hiruzen's Space-Time Source Energy had now reached over a thousand points.
Five hundred of those points came from the Scarlet Crimson Iron he had provided to the Demon Slayer Corps, which had changed the balance between the Corps and the demons to some extent ahead of time.
Another five hundred points came from granting Masahiro the Chakra Seed, which had given this world an entirely new supernatural system.
That was how the system had gained some Spacetime Source Points.
But unlike providing Scarlet Crimson Iron, which had been a one-time deal, spreading the Chakra system would continue to earn him Space-Time Source Energy.
For now, though, Masahiro was the only person in this world who could use Chakra.
If Chakra eventually spread throughout this world, the Space-Time Source Energy Sarutobi Hiruzen could obtain would undoubtedly be astronomical.
"Unfortunately, that'll be quite difficult."
Sarutobi Hiruzen shook his head.
Watching Masahiro try hard to draw out the Chakra inside him, he made a rough assessment.
The people in this world are already far weaker physically than those in the Ninja World...
They have several times fewer cells...
So Masahiro's highest possible achievement will only be Chunin.
Judging by his Chakra reserves...
