From the table of contents, the entire book was an introduction to the concept and basic principles of the Medical Ninja.
It seemed that the introduction to Medical Ninjutsu had already begun back in school.
No wonder Sakura and Rin were able to pick up the study of Medical Ninjutsu so quickly after graduation.
The foundation had already been laid in school.
It's just that the content was extremely dry and boring; no wonder Obito and Naruto couldn't get into it.
But Hyuga Aokawa's eyes lit up.
Yesterday, he was still worrying about his physical fitness not improving in the short term.
He feared being sent out as cannon fodder when the Third Great Ninja War arrived, and he didn't want to expose his Quincy skills so soon.
"Medical Ninja!"
"Isn't this a path that suits me perfectly?"
The positioning of a Medical Ninja itself is as a non-frontline combatant, usually located in the relatively safe rear of the team.
This perfectly masked the inherent impression that "the Hyuga Clan should be scouts and frontline teammates."
Otherwise, bearing the Hyuga surname, he would likely be assigned by default to the most dangerous scouting and frontline Taijutsu positions when the team assigned tasks.
Even if his Quincy skills were gradually revealed in the future, they wouldn't conflict with his identity as a "Medical Ninja" at all.
One could even say they complemented each other: a Medical Ninja healing in the rear, while Holy Arrows provided precise snipes from a distance.
It was simply a perfect tactical combination.
He would be just like Nidalee in the jungle—able to heal and fight, effective at both close and long range.
From the perspective of talent, a Quincy is the epitome of high-precision energy manipulation.
This perfectly met the almost demanding high requirements for Chakra control that a Medical Ninja needs.
Coupled with the Hyuga Clan's innate Byakugan, he was simply a natural-born doctor in the making.
Internal bleeding, organ damage, bone dislocation...
Everything was transparent before the Byakugan, completing an "X-ray scan" in an instant.
Moreover, the ultimate Chakra control developed through Medical Ninjutsu could, in turn, nurture the improvement of Quincy skills.
Of course, this path wasn't one he had to follow blindly to the end.
His plan was to master a few practical Medical Ninjutsu for emergencies.
Meanwhile, securing an official identity as a "Medical Ninja" would be enough for him to legitimately slack off in a team and safely fire arrows from the shadows.
This was just a transition.
During this time, he could continuously accumulate energy crystals and explore the secrets behind the Stone Gate.
Once his physical fitness or Chakra volume underwent a qualitative leap, he would then consider transitioning to other paths.
With the dual potential of the Stone Gate and the Quincy, he might one day be able to go toe-to-toe with those high-and-mighty Ōtsutsuki.
However, he remembered that learning Medical Ninjutsu seemed to require the "Yang Release" Chakra nature.
Logically, everyone should possess both Yin and Yang natures.
But looking at his personal info panel through the Stone Gate, he didn't see himself possessing the "Yang Release" Chakra nature.
So, maybe I need to activate it through specific cultivation?
Or wait for some stroke of luck where a "Favor" directly rewards the relevant attribute?
Regardless, it wouldn't hurt to work in this direction first.
He then immersed himself in the book, reading through it page by page.
Time spent in focus always flew by; in what felt like the blink of an eye, the afternoon classes were nearing their end.
Hyuga Aokawa closed the book and stretched contentedly.
Turning his head, he found his seatmate Hinata Ayane nibbling on a biscuit, her large eyes blinking as she watched him with curiosity.
"What's wrong?" Hyuga Aokawa asked.
Hinata Ayane swallowed the biscuit in her mouth, her voice muffled:
"You seem to really like this book? I talked to you several times this afternoon, but you didn't pay any attention to me."
"Huh?" Hyuga Aokawa felt a bit embarrassed hearing this and apologized with a smile:
"Sorry, I was thinking about some things and was too engrossed to notice."
Hinata Ayane shook her head, just about to say something else.
In the next moment.
The school bell rang.
She abruptly stopped what she was about to say and grabbed her leftover biscuits.
"See you tomorrow!"
Having said that, she vanished from his sight at top speed, leaving Hyuga Aokawa dumbfounded.
"Does she have to be that punctual..."
He shook his head, tidied up his desk, and stood up to leave school.
After going upstairs and showering, he finally lay comfortably on his bed again.
Then, his consciousness entered his Sea of Consciousness.
This time, he moved his attention to the energy crystals column.
520 pieces, plus the original 20, made a total of 540 energy crystals.
If calculated by a fixed ratio, they could increase the Fusion degree by 27%.
Without a second thought, he pressed the "+" sign next to Fusion.
As the energy crystals decreased, the Quincy Fusion degree soared.
He felt something new continuously being injected into his body.
Finally, the energy crystals were exhausted.
The Fusion degree reached 67.52%.
Hyuga Aokawa felt that along with the significant increase in Fusion degree...
...his control over Quincy skills and his Chakra control ability had also improved greatly.
The light arrows that used to dissipate after 30 meters when instantly fired could now reach 40 meters.
The condensation time for long-distance Chakra Arrows was also greatly reduced.
He went to the backyard; since the yard wasn't 40 meters long, he didn't test the light arrows.
Instead, he started testing his Chakra control ability.
He used the Water Release: Water Wall from his last experiment again.
This time, he could reduce the original four seals of the Water Release: Water Wall to three.
And it wouldn't slow down the casting speed.
With his current control ability, if he completed all four seals, the speed of releasing the Ninjutsu would be much faster than before.
However, his reduction of hand seals was different from the Second Hokage's.
He relied purely on high Chakra control ability, replacing the guidance of one seal with mental operation.
Whereas the Second Hokage mostly used his unparalleled talent to optimize one seal that guided one Chakra route...
...into one seal guiding two Chakra routes.
This was also why he could teach the simplified Water Wall to Maruboshi Kosuke.
After all, Maruboshi Kosuke didn't have Chakra control as terrifying as the Second Hokage's.
Afterwards, he tried the hand seals for C-rank Ninjutsu.
For something like Water Clone Technique, he could now reduce the original three seals to one.
If released with one hand, he could cast it using two one-handed seals.
After confirming the boundaries of his abilities once more, Hyuga Aokawa was in high spirits.
Just as he was about to return to his room...
...his grandmother's voice came over.
"I knew it was you, you little brat, wasting the water."
He turned around and saw that his grandmother had also come to the backyard at some point.
She was pointing at the empty water vat and the water stains on the ground, looking at him angrily.
"You're so big and still playing with water; last time you wasted all my water too."
As she spoke, his grandmother picked up a bamboo stick, preparing to hit Hyuga Aokawa.
"Ahhh..." Hyuga Aokawa cried out as he dodged repeatedly.
"Grandma, I'm practicing Ninjutsu!"
"You're still lying, trying to trick an illiterate old lady like me? What Ninjutsu does our Hyuga Clan practice?"
His grandmother said as she raised the bamboo stick again.
"Grandma, look!"
Hyuga Aokawa quickly used the water stains on the ground to release a small water curtain for his grandmother to see.
Seeing the water on the ground form a continuously rotating water curtain under her grandson's control...
...the old lady's anger slowly dissipated, and she lowered the raised bamboo stick.
"Then remember to fill the water vat for me."
"No problem."
"What do you want to eat tonight? Grandma will go prepare the ingredients."
Seeing her grandson practicing hard, the old lady showed her doting side again.
"No need, Grandma!"
Hyuga Fū was still waiting at the Hospital.
If he waited for his grandmother to finish cooking and then ate...
...then went out to buy food for him, Hyuga Fū would have to wait a long time.
Hyuga Aokawa quickly shook his head and said, "Grandma, I want to eat out tonight."
"Eating out again? Which place are you going to?"
The old lady pursed her lips, looking displeased.
"Uh, the sushi place next to the bathhouse!"
Hyuga Aokawa just made up a shop.
"Oh my, that place isn't hygienic. I heard the owner blows his nose and doesn't wash his hands before making sushi."
"Then I won't go there."
Hyuga Aokawa shuddered at his grandmother's words.
"I'll go buy some buns then."
"Grandma can make buns for you. Who knows what kind of lymph meat they use in those buns outside? You can't eat that."
"Then I'll have fried chicken, okay?"
"That oil is all old oil, they never change it..."
"Alright, alright, Grandma."
Hyuga Aokawa interrupted the old lady's "spellcasting."
"Grandma, just let me go out and eat once, okay?"
Under her grandson's coaxing, the old lady finally softened.
"Fine, but don't come back too late, okay?"
"Don't worry, Grandma."
Hyuga Aokawa prepared to go back to his room to change clothes.
"You're going out before you've even filled the water for me."
His grandmother looked at him unhappily.
"You father and son have no memory; I always have to tell you to do something three or four times."
"Oh, Grandma, I'll do it right away."
After Hyuga Aokawa filled the water vat he had wasted...
...he changed his clothes and went out.
Walking on the street, Hyuga Aokawa looked at the various delicacies on both sides.
There was such a dazzling array that he really didn't know what to eat.
Suddenly.
He saw a small shop ahead that was very conspicuous.
He walked over to take a look.
Ichiraku Ramen!
Hyuga Aokawa's eyes lit up.
This is it!
Last time, he had wanted to try this ramen place that Naruto was always thinking about.
But he didn't get to eat it.
This time, he had to give it a good try.
"Little Ninja, what kind of ramen would you like?"
Ichiraku greeted him warmly.
Hyuga Aokawa looked at the various flavors of ramen and was about to speak.
His peripheral vision suddenly caught a familiar figure sitting in a corner seat behind the curtain.
He turned his head and found that it was actually Hinata Ayane.
