Behind Konoha Village's mountain.
Among countless mountains, an invisible breeze blew.
Might Guy's watermelon-shaped hair swayed in the wind as he looked at Satoru with unprecedented seriousness.
Kakashi put down his book and glanced at the eagle flying in the sky and the two children.
"Many years have passed, I wonder how much Satoru has grown in these two years?"
This man is getting stronger and stronger.
Boom!
A leaf fell.
Two figures 'swish' collided.
Satoru and Might Guy pressed their hands together, facing each other with smiles.
Whoosh whoosh!
In just the blink of an eye, the two had exchanged blows for several rounds.
Both were masters of Taijutsu, using Instantaneous Body Technique, Konoha Style, and self-created Taijutsu, neither gaining an advantage for a while.
"Might Guy, I'm getting serious now, be careful." Satoru executed a back-spin cyclone kick, pushing Might Guy back a bit, then formed a hand sign with one hand.
Whoosh!
His right hand visibly turned black.
He clenched his five fingers, not forgetting to remind Might Guy, as this power was no joke; it wouldn't be good to injure a crucial combat force of the Village during a spar.
"Come on, I didn't expect you, a Genjutsu-type Ninja, to have cultivated Taijutsu to this extent.
Gate of Opening, open,
Gate of Healing, open,
Gate of Life, open."
Might Guy was boiling with excitement, looking at Satoru's black hand, knowing it was some kind of Ninjutsu that would increase physical strength.
Because Satoru had said before the battle that he would only fight him with Taijutsu, as a Jonin, Might Guy's experience immediately allowed him to roughly assess the ability.
Taijutsu is a Ninja's direct means of attack, so he made his judgment based on that.
And he absolutely could not be hit by this move; the large crater on the adjacent mountain wall was made by this move.
So he stopped holding back and also used his trump card.
Directly opening to the Third Gate.
The blue Chakra pushed away the air around his body, forming a stark contrast with Satoru's black arm.
Whoosh!
The two children in the sky pulled out a bag of melon seeds each and started munching on them, watching the battle below.
Not yet Ninja themselves, they naturally couldn't see the two's speed clearly, but they could see the shattered rocks flying from the ground.
And the subtle pauses that occurred during occasional clashes.
Rumble!
Even Might Guy, with three Gates opened, had to retreat three paces when facing the power of Iron Block.
Every punch from Satoru created a large crater in the ground.
And that wasn't all;
He even used this move as a normal attack, without a moment's pause, forcing Might Guy to rely on the speed of Eight Gates to contend with him.
And he could only contend.
Satoru was also a sensory Ninja, his reaction speed was inherently fast, and even though Instantaneous Body Technique wasn't his speciality, it was still beyond what an ordinary Jonin could achieve, causing Might Guy to be constantly constrained.
"So cool, Dad, two punches and he made a big crater in that mountain."
Tenyu looked at the commotion below, his eyes filled with admiration.
Maki was the same: "That watermelon-head isn't bad either; he manages to dodge Dad's attacks every time, but if he gets hit, he'll be all bruised up."
"This move is so cool; when I grow up, I'll ask Dad to teach me Taijutsu, I want to be that cool too." Tenyu 'crunch' bit a melon seed, feeling a bit of longing for the future.
Thinking of making a big crater with one punch, it felt so satisfying.
"Then I want to learn it too." Maki expressed the same sentiment.
"You? You're a girl, you should learn Dad's life Ninjutsu, that's better; with just one Ninjutsu, you don't have to wash dishes, mop floors, or cook, how great is that!"
"No way, I want to smash big rocks with one punch."
"I advise you to learn life Ninjutsu, otherwise, it'll be like when Dad goes out, Grandpa and Mom have to wash everything by hand, it's so troublesome."
The two imagined their future, finding the Taijutsu battle below very cool.
"Wow, the watermelon-head changed again, his body turned red, and he's making such a loud sound when he runs."
Down below, after a long battle without success, Might Guy opened the Fifth Gate, the Gate of Limit, his heart boiling.
With the Gate of Limit opened, the sonic booms from his running stirred up the ground, and Satoru finally fell a step behind in speed, only able to defend and counterattack.
Using attack speed to compensate for the lack of movement speed.
"The Fifth Gate of Eight Gates, is it? As expected, it's a desperate move, but it will damage the body, isn't this impulsive?" Satoru thought, analysing internally.
Feeling Might Guy's extreme speed, he could only rely on his senses to defend and counterattack.
To prevent Might Guy from getting carried away, he decided to use the results of his two years of training in Genjutsu of Phantoms.
Genjutsu of Phantoms had been researched for two years,
Naturally, it wasn't fully perfected yet, but the main framework was largely complete and could be used in every type of battle.
Might Guy approached, unleashing a Konoha Great Whirlwind and continuous Konoha Strong Fist attacks.
"Genjutsu of Phantoms: Instant Opening."
Sizzle~
The black arm receded into his skin, and Satoru erupted with a powerful aura, instantly disappearing from in front of Might Guy, who was in the Gate of Limit state.
In the blink of an eye, he appeared behind him, spread his five fingers, and flicked him on the back.
Might Guy felt a cold sweat break out and wanted to let go, but it was too late; the finger flicked his back.
Whoosh!
There was no imagined attack, but rather more like Gentle Fist, a pushing force that sent him tumbling several times on the ground.
Finally, Might Guy rolled his Byakugan: "Damn it, I lost in Taijutsu. I'll go run ten laps around the Village when I get back…"
Satoru retracted his Genjutsu of Phantoms and came to his side, looking at Might Guy's determined face, he could only say, as expected of you, Might Guy.
He pulled out a special pill from his Ninja tool pouch, put it into Might Guy's mouth, and then used a recovery-type Genjutsu of Phantoms he often used. As his stamina recovered, Might Guy's body developed an extremely strong desire to absorb, taking in the ingested nutrients into his body to maintain his health.
His physical talent, which allowed his Taijutsu to keep up with Might Guy's abnormal level, relied on this Ninjutsu. It was incredibly useful, with no side effects, only requiring Chakra consumption.
But it wasn't long.
Might Guy felt the difference in his body; his stamina seemed to be recovering rapidly, and the fatigue from opening the Eight Gates gradually cleared up.
"This is… Medical Ninjutsu?"
This Ninjutsu reminded him of the day his father died; that day, Satoru had also used a Ninjutsu that could restore his physical stamina.
Although after the Ninjutsu wore off, his body would enter a state of fatigue.
He didn't expect Satoru to also know Medical Ninjutsu; it was truly amazing.
"Yes, how about it, are you feeling better?" Satoru smiled.
This Ninjutsu's understanding of the human absorption system was a bit difficult, and different people's meridian systems and absorption systems also varied. Luckily, he was a sensory Ninja.
He didn't need to use Chakra or instruments to investigate bit by bit.
Moreover, he was the leader of the Analysis Team, and his analysis of the human body was also very strong.
Combining these, it was the birth of a super hexagonal Ninja.
"Good, incredibly good. Can you teach me this Ninjutsu?
For a Taijutsu Ninja, this Ninjutsu is truly amazing."
A Ninjutsu that could restore stamina and injuries was simply too appealing to Might Guy.
He had also studied Medical Ninjutsu, but Medical Ninjutsu required too much knowledge to learn, so it was simply unfeasible.
Seeing Satoru use it so easily, he felt it shouldn't be too difficult.
Satoru scratched his head: "You… better not. This isn't easy to learn at all."
Just understanding the human absorption system and the impact of the meridian system on the human body, these theoretical knowledge alone took him a month to deeply learn.
The actual implementation of the Ninjutsu later was even more difficult, taking half a year to develop this one Ninjutsu.
Moreover, this technique was a type of Genjutsu, so it was even more impossible for Might Guy to learn it.
