Darkness Technique is a standalone system within Genjutsu.
Unlike visual Genjutsu, which influences the enemy's Chakra through sight.
And unlike auditory Genjutsu, which transmits Chakra through sound.
This is a wide-range Genjutsu that transmits Chakra into the air, similar to the process of releasing Ninjutsu, but with the effect of Genjutsu.
Therefore, integrating Darkness Technique into his own Genjutsu system is still a bit difficult for Satoru.
At least it's not something that can be accomplished in a day or two.
Satoru didn't spend all his energy here; he mainly spent a little time each day accumulating experience until he had enough to complete it.
Currently, his main research is still on ordinary Genjutsu.
Such as visual and auditory types…
As well as the research on the Mind Reading Technique series.
Fire of Eight Fragrances, for example, is a specific application of his research into auditory Genjutsu, using sound to transmit Chakra and affect the enemy's five senses.
"Ah, ah, ah, it hurts so much…"
Izuno Zaizai plopped down on the ground, tears welling up from the pain.
Looking at the pillar in front of him, he really wanted to destroy it with his family's secret technique.
But seeing Satoru practicing music nearby, he decided against it.
Fuma Shikun was the same; this precise control of Chakra was simply too difficult.
At this moment, his middle-parted hair and overalls were covered in sweat.
He was exhausted.
"Hey, try harder, I'm starting to get a feel for it." Inuzuka Hana's feet lifted off the ground, and she slowly walked at a ninety-degree angle on the pillar.
No sooner had she spoken than she fell down again.
Her face was excited; this feeling was truly amazing.
It wasn't difficult at all!
Zaizai's chubby face turned to her: "Big Sister, how did you do it?"
Fuma Shikun also looked at her.
They hadn't felt anything at all.
Sometimes, they would fall down after only taking a couple of steps.
Inuzuka Hana encouraged them: "Like this… like that… and then… you'll find the feeling…"
Chirp chirp~
Thump thump thump~
Just then, a familiar yet different piece of music sounded in their ears.
A slight spiciness emerged from their throats, then shot straight to their foreheads.
The fatigue from before instantly vanished, and they felt invigorated.
"Work hard, when you finish, you'll be free.
Otherwise… hehe…" Satoru raised the harmonica in his hand, signaling them not to overthink and to practice diligently.
"Yes… yes…"
They never wanted to experience that Ninjutsu again; it was simply too terrifying.
The feeling of their foreheads being rushed made them think they were going to heaven to see their great-grandmother.
Not daring to slack off, the three continued to practice.
Satoru watched their every move.
He frowned slightly.
Inuzuka Hana was fine; she had good talent in Chakra control.
But the other two,
Their talent was a bit poor.
It seemed that in a short time, there was no hope for these two little brats to complete this basic training.
He then relaxed his brow.
No rush, he was only training the younger generation incidentally; he wasn't trying to cultivate them into Six Paths Sage.
…
"Brother, is that Bad Uncle really here?"
Sasuke held Itachi's hand, slowly walking beside him, looking at the vast forest and road around them.
Itachi smiled upon hearing this: "Didn't you say he was a Bad Uncle? Why do you still want to find him?"
"But the brother he made is really good-looking." Sasuke extended his right hand, holding a small Itachi figurine.
The sunlight shone on the figurine, reflecting light.
He had played with it a lot.
Uchiha Itachi smiled at the figurine, then turned his head, his smile returning to a calm expression.
The bags under his eyes were even larger.
Clearly, he had experienced many things in the past one or two months.
Making him even more mature.
Itachi replied: "The Bad Uncle you speak of basically practices at this Training Ground 98 every day; he'll definitely be here at this time."
"Brother, why can the Bad Uncle train every day, but you have to go on missions every day?"
Sasuke asked innocently.
He didn't understand; whenever he wanted to play with his brother, even if it was just watching him train, Sasuke was willing.
But,
Most of the time, he was on missions,
There was hardly any time to play with him.
Itachi smiled: "Because brother is only a Genin, he needs to improve his strength and experience, so he's quite busy.
Once brother becomes a Jonin, he'll have more time to spend with you."
Sasuke half-understood: "Just like Dad?"
"More or less."
Thump thump thump!
"Hey, brother, what's that?"
Sasuke looked up, a shadow enveloped them, and a tall stone wall blocked their view.
Itachi's eyesight was better; he could see Satoru sitting on the edge of the wall, playing some music.
"Well, this should be the Earth Release Ninjutsu released by your Bad Uncle; he should be training."
Itachi explained to Sasuke.
…
"Hmm? Why are they here?"
Satoru sensed Uchiha Itachi and Sasuke entering his perception range.
Could they also be coming to Training Ground 98 to train?
That shouldn't be the case; the Uchiha have their own training ground.
They wouldn't be here to find him, would they?
Soon, Itachi brought Sasuke to the base of the Earth Release: Earth-Style Wall.
"Senior Satoru."
"Oh, Itachi, are you looking for me for something?
Also, why aren't you calling me brother anymore?"
Satoru leaped down from dozens of meters high, landing lightly in front of them without causing the slightest disturbance.
Just like a feather falling to the ground.
Uchiha Sasuke hid behind Itachi, watching Satoru's movements, feeling how amazing he was.
He actually jumped down from such a height.
Uchiha Itachi's face showed embarrassment upon hearing this.
Somehow, after not seeing him for a while, calling him brother felt a bit off.
"Senior, don't tease me; my brother wants to find you."
Itachi said.
Satoru's mouth curved into a smile upon hearing this; he saw the figurine in Sasuke's hand.
"Oh, I thought you came to spar with me.
I recently developed some new Genjutsu and wanted to test them on you, the Sharingan wielder!"
He feigned regret.
Itachi was speechless.
Although his progress was visible after this period of training, he still didn't want to face Satoru's Genjutsu.
He hadn't found a way to break Satoru's Genjutsu yet.
Or rather,
His Chakra was insufficient, and many of his techniques were not enough to break it.
"Bad Uncle, I want to buy a few more brothers like this."
Sasuke held up the small Itachi figurine in his hand, saying in a childish voice.
"Alright, I'll grant your wish, but first let Uncle give you a hug."
Satoru hadn't expected the two brothers to come looking for him just for this; his mischievous side emerged, and regardless of whether Sasuke agreed or not, he squatted down and hugged the nearly four-year-old Sasuke.
Sasuke, of course, resisted and tried to struggle.
But who was Satoru? He held him down with one hand.
Last time he just picked him up; this time, he'd just hug him.
"Don't move, I'll weave a few small Itachi for you."
After Satoru finished speaking, he pulled out bamboo threads from his ninja tool pouch, and in less than a few seconds, several small Itachi figurines with different poses appeared.
They were all chibi-version, standing and sitting.
The items they held were also different; there were Shuriken, Kunai, and so on.
Sasuke's eyes grew brighter and brighter as he looked at them.
