[Under your leadership, the Hidden Sand Village and the Hidden Rain Village have agreed to the ninja exchange program, promising to send their ninja to Konoha for exchange and study.]
[This program will effectively promote the Will of Fire and advance the unification of ideology.]
[Reward: Demonic Flute: Phantom Sound Chains (Grandmaster)]
Phantom Sound Chains…
Kyohiko's gaze swept over it.
This technique was not the strongest among genjutsu, but as a relatively special sound-based genjutsu, its value was indeed good.
The essence of genjutsu is to interfere with the flow of chakra, and what makes sound genjutsu special is that it is difficult to defend against.
The principle of this technique is not difficult, as long as one controls their chakra and gives the sound a special chakra effect.
However.
To take it to a higher level, one needs to consider speed, silence to make it unnoticeable, or to make its scale and intensity even greater.
Kyohiko took a short time to process the knowledge in his head, completely absorbing and digesting this technique.
Then, he began to think and expand upon it.
The effect of this technique was not particularly practical for him, but what if he enhanced and improved it?
For example—
Combined with the Chakra Armor, and the kind of ninja tools that Orochimaru would later use in conjunction with sound ninjutsu.
A sound genjutsu released by one person can at most control a few people.
But if several people release it together, or if the genjutsu is amplified through some kind of ninja tool or device…
The effect would be completely different.
On the battlefield, a group-cast genjutsu would have a very terrifying effect.
…
Outside the hospital, Yuhi Kurenai was teaching Yakushi Kabuto some techniques of medical ninjutsu and genjutsu. After speaking for a moment—
She noticed that Kabuto seemed to have a momentary lapse in concentration.
This lapse was very brief, but as a genjutsu ninja with strong spiritual power, Kurenai caught it instantly.
She followed his line of sight out the window.
She only saw a surprising and unexpected figure standing there.
Seeing her gaze, the other party waved slightly.
Kyohiko?
Why is he here?
Kurenai grumbled inwardly.
She pondered for a moment and said, "Kabuto, Kyohiko-kun might have something important to discuss with me. You should practice the few genjutsu I taught you first."
"Yes, Kurenai-sensei."
Yakushi Kabuto was very respectful.
Watching Kurenai leave, he turned his head to look out the window.
Kurenai taught him three genjutsu.
Demonic Illusion: False Surroundings Technique, Demonic Illusion: Hell Viewing Technique, and Temple of Nirvana Technique.
The difficulty of these three techniques increased progressively, with the most difficult being the third one, which involved emotions and spirit.
However.
To be honest, he didn't think the difficulty was that high. At least he had already learned the first two.
Compared to genjutsu, Kabuto was more curious about why Kyohiko was looking for Kurenai.
Unfortunately.
He couldn't go out, and with Kyohiko's abilities, he would definitely be discovered. Going out wouldn't allow him to hear any news.
Of course.
The most crucial thing was—
It was useless even if he heard it!
His goal was to become Kyohiko's disciple, not to eavesdrop on gossip.
Kabuto straightened his mindset and focused on studying the "Temple of Nirvana Technique."
…
Outside the Konoha Hospital, in a not-so-vast small forest.
Kurenai was stunned for a moment when she saw Kyohiko take out a flute, and then her face turned rosy.
"Kyo, Kyohiko, did you look for me just to let me listen to a song?"
"Don't be hasty."
Kyohiko smiled, then took out the flute and began to play softly.
Thanks to the grandmaster-level Demonic Flute genjutsu, he was no longer ignorant about the flute, and his skills were quite good.
After a while.
"Wooo—"
The sound of the flute was melodious, echoing in the forest, but it was limited to this forest.
Kurenai sat on a rock, a smile on her lips, her fingers tapping her knee gently to the beat.
However.
A few seconds later, she gradually felt that something was wrong.
Along with the sound, a strange sense of loss of control emerged, as if her body was no longer her own.
After a second or two, her vision went blank.
Not right!
This is genjutsu!
Kurenai immediately realized and quickly tried to release the genjutsu.
However.
The difficulty of releasing the genjutsu was greater than she had imagined, because the sound was continuously interfering with her chakra, making it impossible for her to straighten it out.
After an unknown number of seconds.
She felt a tap on her shoulder, and the previous scene quickly reappeared. Kyohiko stood in front of her.
"Sound genjutsu? Did you develop it?"
Kurenai was a little surprised.
Kyohiko thought for a moment and said, "I guess so."
If you stretch the timeline, or bring in another timeline, it definitely wasn't created by him.
As for now.
Whether Tayuya could even learn ninjutsu was a question, let alone create this kind of sound genjutsu.
Kurenai couldn't help but marvel.
"A very strong genjutsu, especially when you use it. It will continuously interfere with my chakra, increasing the difficulty for me to break it."
"It's nothing. It's not that the technique is strong, but that my chakra and spiritual power are strong, and can directly suppress your chakra."
Kyohiko replied.
Kurenai was slightly taken aback, then nodded silently.
Indeed.
The situation just now was equivalent to her using genjutsu on a child. Even if the other party had mastered chakra and the method to break genjutsu, it would be impossible to break.
The difference in magnitude was too great!
Thinking of this, Kurenai added, "The preparation process is also very troublesome. Can it only be used with a flute?"
On the battlefield, who would take out a flute for no reason?
The enemy would naturally be on guard when they saw it.
Therefore.
If she were to think of an optimization plan, she would prioritize this direction.
"I'm trying."
Kyohiko replied.
Then, he tried to use a whistle instead.
A whistle doesn't require taking out a ninja tool and can directly produce sound. In terms of suddenness, it is definitely much stronger than a flute.
The "grandmaster-level" Phantom Sound Chains was not a problem in this regard.
It was just that the effect needed to be tested.
A few seconds later, Kurenai broke the genjutsu and said, "It's much weaker than before, because the change in the sound of a whistle is not as strong as a flute, and its effect on chakra is limited."
"As expected."
The technique was still the same technique, but it wasn't without reason that this technique relied on the "Demonic Flute."
After that, he took out another instrument.
A whistle.
Compared to whistling with his mouth, it was naturally more complex, and through the device, the Phantom Sound Chains was also more proficient.
This time Kurenai couldn't break free, but…
With her perception, unless Kyohiko maintained the sound or kept this distance, she could break it once the distance increased.
After multiple rounds of attempts, Kurenai even forgot about Yakushi Kabuto.
She was very interested in this genjutsu!
After much experimentation.
Kyohiko probably had an idea. He looked at Kurenai and said, "Do you want to learn this technique?"
"Mmm, mmm, mmm!"
Kurenai nodded repeatedly, her small face filled with excitement.
Of course she wanted to learn!
Sound genjutsu, a whole new field.
Although it wasn't very strong, it might not be worthless if it was extended and developed further.
For example, during surgery, to make the patient fall asleep faster.
Or.
On the battlefield, using a special sound genjutsu to assist teammates.
Kurenai was quickly thinking and piecing together possible uses.
However.
Before that, she had to learn this genjutsu first!
Kyohiko smiled and briefly explained the principle. Kurenai nodded slightly after listening, indicating that she would go back and study it slowly.
…
"Genjutsu? Not interested!"
Orochimaru was unenthusiastic.
He didn't research everything. Things like genjutsu, which had little potential and didn't fit his interests and hobbies, were completely out of consideration.
Fortunately.
Now, he didn't have to do everything himself.
"Yazawa is not bad. Although he is relatively weak in ninjutsu, these theories can be learned and supplemented later."
Orochimaru smiled and said, "For simple research like this, I'll just hand it over to him later."
"I have the same idea."
Kyohiko nodded.
He naturally didn't think that Orochimaru would be interested in the Phantom Sound Chains.
In the original timeline, Tayuya, as Orochimaru's subordinate, developed this genjutsu, and Orochimaru didn't go to learn or research it.
It could be seen that in Orochimaru's eyes, the value of this genjutsu was not high.
And that was the truth.
The upper limit of sound genjutsu was not the Phantom Sound Chains, but the Demonic Illusion: Toad Confrontation Chant of Mount Myoboku.
This genjutsu was an extension of the Mount Myoboku Sage Art "Frog Song," and required both Fukasaku and Shima to use it together.
However.
"Frog Song" was a natural ability of the toads of Mount Myoboku. Humans could master Sage Arts like Frog Kata, but it was still very difficult to learn Frog Song.
Therefore.
It was basically impossible to learn this technique.
After some arrangements, the tasks at hand were once again outsourced, and Kyohiko could focus on his own affairs—
The commissioned mission from the Land of Snow had not been completely dealt with yet.
Now there was another mountain-opening project in the Land of Rain and the Land of Wind.
He was busy too!
Fortunately, Rasa had already relented.
The project in the north, subcontracted to Rasa, was a sure thing!
…
"You're going to open the mountain alone? Can you do it?"
"No problem."
Kyohiko was full of confidence.
Although the mountains between the Land of Rain and the Land of Wind were relatively high, to destroy a mountain, you don't need to completely level it. You just need to destroy a few key structures.
Of course.
The most important thing was—
The profits from this had already been received, and there was no subsequent additional commission.
It was the same amount of money whether one person went or a group of people went.
Why ask for trouble?
Tsunade nodded in agreement. After that, she mentioned Kakuzu.
Kakuzu was captured by them, and as a result, the Hidden Waterfall Village sent people.
Konoha naturally didn't care.
They had completely squeezed Kakuzu's value. Even if the Hidden Waterfall Village wanted to take him away directly, they could—
Provided they had the ability to control Kakuzu.
They didn't.
So, Kakuzu died.
…
Hidden Grass Village.
"Elders, Konoha has sent a cooperation proposal. The wording is quite sincere. Let's discuss it."
Mui took out the scroll and placed it on the conference table.
The two elders exchanged a glance, and one of them picked up the scroll.
Mui sat in his seat, closing his eyes to rest. He was very confident in this plan, after all—
Konoha had already settled the Land of Rain and the Land of Waterfalls.
If they didn't agree, what was the difference between that and waiting for death?
If it were the previous Hidden Grass Village, the leader and a dozen elders might still have to haggle for a while, but now it was different.
Ever since that ninja from Konoha named Might Dai kicked a terrifying kick in the Hidden Grass Village, only these two elders were left.
Things suddenly became convenient and clean.
Mui waited for a moment, opened his eyes and said, "Do you have any thoughts?"
"This, leader, this plan, I feel…"
They looked at each other.
Jointly developing the river to make trade routes and transportation more convenient, and everyone makes money together.
The slogan was very loud.
However.
Upon careful thought, within the area the river flows through, Konoha is the most powerful, so Konoha will have the strongest control over this river in the future.
They didn't understand much, but they vaguely felt that there was no such thing as a free lunch, and there was probably a trap hidden.
Mui smiled slightly and threw out a second scroll.
The two elders took a look, then sighed and closed their eyes.
"We can only cooperate!"
Cooperating with Konoha, they could still get a share.
If Konoha cooperated with the Hidden Waterfall Village unilaterally and directly dug a canal with ninja, their Land of Grass would get nothing.
Even.
In the future, it's not certain that with the opening of the trade route between Konoha and the Land of Waterfalls, the trade of the Land of Grass would also be greatly affected.
Although this was a matter for the Land of Grass, if the Land of Grass had less money, the share given to the Hidden Grass Village would naturally be less.
They could still figure this out.
…
Hidden Rain Village.
"The message from Konoha, what do you think?"
"We have no choice but to agree."
Yahiko answered sincerely.
Then, he stated his analysis—
The Land of Waterfalls and the Land of Grass had already agreed. Whether they agreed or not didn't mean much.
To put it bluntly, this was a decision made by Konoha to strengthen its connection with their Hidden Rain Village, purely to give them a share.
Hanzo nodded lightly.
He could naturally see it, and he only asked to hear Yahiko's opinion.
Walking out of the office, Yahiko went to do his own things.
But.
It wasn't until he was with Konan and confirmed that the surroundings were safe that Yahiko sighed, "I already understand what Kyohiko wants to do!"
"You understand again?"
Konan said with a half-smile.
Yahiko's face turned red, and then he said, "I really understand this time!"
Konan smiled and said, "Alright, so, you weren't completely honest with Hanzo?"
"Sort of? I think, on the one hand, Kyohiko's plan is indeed to benefit everyone and make us grateful to Konoha."
Yahiko stated his analysis, "On the other hand, with more contact and communication, combined with what he has done before, the future Land of Rain and Hidden Rain Village will become more and more friendly to Konoha and the Land of Fire."
Using interests as a bond and communication and words as a bridge to achieve the union between countries.
Yahiko couldn't help but exclaim, "Kyohiko-kun is a genius. He will make the Land of Rain more and more inseparable from the Land of Fire."
Konan pondered for a long time and nodded lightly.
"Indeed, the more inseparable, the greater the cost of starting a war or betraying."
In other words…
The more you get, the more it hurts to give it up in the future.
Of course.
If the Land of Rain were a major country, this rule might not apply.
Therefore.
This "river" did not pass through the Land of Wind.
The Land of Fire, various small countries…
Konoha already had the upper hand!
At the same time, this also meant that the Hidden Rain Village and Hanzo had lost the opportunity to unite the small ninja villages to achieve their own demands.
"Before the war comes, unite as many forces as possible."
Yahiko's pen wrote the names of the villages on the paper, "Kyohiko-kun seems to be overestimating the enemy's strength."
"After all, the opponent is Uchiha Madara."
"That's true."
