The hairstyle resembling two rabbit ears was tugged, making her head shake violently.
She struggled in agony, but it was utterly futile.
She was... going to suffocate.
For a long time... a very long time...
The thunderstorm vanished, and dawn arrived.
Just as the last trace of darkness was about to fade, the rampage reached its end.
Squelch...!
"Ugh~!"
The final torrential downpour fell. Then... the thunderstorm completely ceased, and the shadow silently receded as well...
"...Cough, cough... cough cough cough cough!!!"
Ringo Yūri began coughing violently.
Only after the shadow had completely disappeared from the room and the light outside shone in did she barely stop coughing.
"Phew..."
She let out a long breath and stared at the bright ceiling.
Ringo Yūri lay on the bed, her thoughts drifting far away.
In the end, she could only sigh. "What a... monster..."
Morning.
Nonō woke up.
It was already completely light outside.
She had slept deeply last night.
Medical Ninjutsu was an extremely Chakra-consuming practice.
Therefore... it was understandable that exhaustion had sent her into deep sleep.
Still, being able to sleep so deeply while surrounded by enemies probably had everything to do with Young Master Akira Sarutobi.
Whenever she saw his confident expression, she felt that he could accomplish anything. It was truly reassuring.
After washing up, Nonō entered Ringo Yūri's room.
"Good morning, everyone..."
With everyone gathered, they began a new day.
"You... didn't sleep well last night?" After checking Ringo Yūri's condition, Nonō felt puzzled.
"..."
Ringo Yūri rolled her eyes.
Naturally, Nonō had no idea what had happened last night.
She used Medical Ninjutsu Chakra to examine Ringo Yūri's body, reaching the same conclusion as yesterday.
"Ringo Yūri, citizen of the Land of Water, condition stabilized from critical illness, height one meter forty-three, suboptimal health..."
After probing for a moment, Nonō stood and brought Ringo Yūri a kettle.
"I'm not drinking."
Ringo Yūri, the patient, grumbled weakly.
"Anyway, I'm not thirsty... or hungry..."
Without giving it much thought, Nonō began another round of treatment.
"..."
Akira Sarutobi watched the two of them, his gaze settling on Ringo Yūri.
A system prompt was displayed before the retina of his right eye.
[Inject Will of Fire into Ringo Yūri]
[Current progress: 30%!]
Over the next two days.
The group continued according to plan.
Ringo Yūri's physical condition improved rapidly, fully demonstrating Nonō's superb Medical Ninjutsu.
After all, Kabuto's Medical Ninjutsu in the original story had also been exceptional, and he had been taught by Nonō.
Even across all of Konoha, Nonō's Medical Ninjutsu was extremely formidable.
Only Princess Tsunade and a very few others surpassed her in medical expertise.
With enough wild food and soldier pills, Akira Sarutobi's training advanced by leaps and bounds.
He had previously spent a week fusing Steel Style.
Now, he had officially taken off. All he needed was to continuously hone his proficiency with the Steel Style: Kekkei Genkai.
Akira Sarutobi had not neglected physical training for his main body either.
Physical strength could not be trained through the Shadow Clone Power-Up Training Method, but even so, with his own firm willpower, constant refinement, unwavering persistence, and long-term training, Akira Sarutobi could continue improving.
It was difficult for an ordinary ninja to sustain such diligent training.
Throughout the entire Naruto series, only Might Duy, Might Guy, and Rock Lee possessed such an unyielding attitude toward taijutsu training.
And Akira Sarutobi possessed one advantage over those three.
The system.
As long as his "right eye" observed his body, seeing the thermal imaging grow visibly stronger and increasingly scorching, Akira Sarutobi could keep persevering.
That kind of positive feedback, where effort was visible and effort brought immediate returns, was the best motivation.
If someone could accurately see the extent of their progress, even quantify it precisely, who would be unable to persist?
As time passed.
Akira Sarutobi grew stronger and stronger.
Through Ruri Hyuga's Byakugan, the intensity of Akira Sarutobi's Chakra continued rising, while the "film" over the surface of his skin grew thicker and thicker.
Bang!
Akira Sarutobi threw a punch.
A faint white aura appeared over his fist.
In Akira Sarutobi's eyes, everything seemed to have become slow motion.
The posture and speed of his punch, every single detail.
Even droplets of dew falling from the tree branches above were crystal clear.
It was as though a camera lens had been switched to slow playback.
Boom!
The thick tree before him was struck by that punch, and its trunk exploded with a thunderous crash.
A massive dent appeared, with countless cracks spreading outward.
At that moment, enlightenment struck Akira Sarutobi.
With his full attention focused on observation, he naturally activated a new function of his right eye.
A waterfall-like stream of data flowed past the retina of his right eye.
Finally...
[Will of Fire System...]
[New function loading...]
[Dynamic Vision module... activated!]
"..."
Akira Sarutobi maintained his punching stance, frozen for several seconds.
Of course, he was not spacing out.
His attention was focused on the new function.
Dynamic Vision, also known as Reflex Nerve.
It was one of a ninja's fundamental metrics.
A simple example made the importance of Dynamic Vision clear.
Before Kakashi obtained the Sharingan, when he used Chidori and charged at high speed, he could neither clearly see his own attack nor the enemy's counterattack.
That was why Minato Namikaze told Kakashi in the original story not to use that ninjutsu anymore, because he would definitely die.
Only after Kakashi obtained Obito's Sharingan was Chidori truly perfected.
The reason was that Kakashi did not possess the Dynamic Vision of the Sharingan or Byakugan.
And Flying Thunder God demanded Dynamic Vision and Reflex Nerve several times, perhaps even dozens of times, more than Chidori did.
Minato Namikaze could even evade Fourth Raikage Ay's extreme speed through his own abilities.
From that alone, it was obvious that Minato Namikaze's talent far exceeded Kakashi's.
Therefore... the importance of Dynamic Vision and Reflex Nerve went without saying.
"..."
Akira Sarutobi withdrew his fist and swept his eyes around.
The Kirigakure ninja outside the barrier immediately grew tense. After all, the force of that punch had been truly terrifying.
"..."
Akira Sarutobi withdrew his gaze.
With just one glance, he understood that his Dynamic Vision had already increased severalfold.
"It's about time to head out..."
Breakout? No, a slaughter!
Akira Sarutobi returned and looked at everyone, who were ready to depart.
After three days of treatment, Ringo Yūri had recovered considerably.
Her complexion was merely somewhat pale. She was completely out of danger, having gone from critically ill to weak after a serious illness.
"Let me make this clear first. I no longer have my Lightning Blades, and I've only just recovered from a serious illness..."
Ringo Yūri spread her hands, indicating that she did not have much fighting strength.
So... do not count on her.
"You just squat in the back and cast some ninjutsu." Akira Sarutobi assigned her a position.
Besides, Akira Sarutobi was not unprepared.
Ringo Yūri had been fitted with insurance.
It was a small Explosive Tag.
This type of Explosive Tag was only the size of a card. Its advantage was that it could be made by hand and cost nothing. Its disadvantage was its limited explosive power and range.
