Slacking Off During Battle, Initiating Simulation

At that time, could Obito still afford to be so naive?

"Let's talk later, Obito. I need to go help with the treatment."

Nohara Rin lifted the tent flap and caught sight of Shimizu.

Without a change in expression, he was treating the wounds of another patient on the adjacent bed.

Under Shimizu's guidance, Rin's medical skills had improved by leaps and bounds.

Although it was her first time dealing with such large-scale trauma, she carried out her tasks in an orderly manner.

...

The next day.

Today marked the second day since arriving at the medical base.

Namikaze Minato and a group of Jonin had headed to the front lines, while Shimizu and others were reassigned to a more remote medical outpost—more secluded, but relatively safer.

"Be sure to avoid any strenuous activity for at least three days, or your wound may reopen."

Shimizu advised a patient.

Medical ninjutsu was not omnipotent. New patients arrived every moment.

All the medical ninjas could do was perform emergency treatment, healing wounds to a certain extent and leaving the rest to the ninja's natural recovery.

"Take a break. I'll take over."

While Shimizu was busy, a kunoichi with short black hair walked in.

Her hair was tied back, with strands framing her face.

She had a delicate and pure appearance. The chainmail under her black robe clung tightly to her figure, her chest subtly rising and falling.

With practiced movements, she took over treating Shimizu's patient, allowing him to rest.

"Alright, I'll take over when it's time."

Shimizu nodded.

The woman before him was Shizune, Tsunade's senior disciple.

Her uncle was Katō Dan, the ninja who had shared an ambiguous relationship with Tsunade.

After Dan's death, Tsunade took in Shizune and taught her medical ninjutsu.

This war was proving even fiercer than the last.

Tsunade had developed hemophobia and could no longer serve as a medical ninja.

Shizune was sent in her stead, both to assist and to gain experience.

Shimizu wiped the blood off his sleeve and left the tent.

Only after his figure disappeared did Shizune let out a breath.

"Just how did Shimizu learn medical ninjutsu?"

She looked around the tent at the injured ninjas Shimizu had treated. Even now, she couldn't suppress her astonishment.

As the disciple of one of the legendary Sannin, she had arrived at this outpost a week earlier than Shimizu.

When she first heard he was going to treat the most severely wounded, she dismissed it as arrogance.

Even she had struggled with such injuries upon arrival. Wasn't he being overconfident?

But after witnessing his astonishing learning speed, she found herself at a loss for words.

Shimizu's unparalleled chakra control allowed him to reconnect severed limbs, meridians, and blood vessels at a speed far beyond that of ordinary medical ninjas.

His chakra reserves, disproportionate to his age, enabled him to treat multiple patients in a single sitting.

His efficiency was nearly equivalent to three of her working simultaneously.

Every time she saw Shimizu, she felt pressured, as if he were Tsunade's disciple and she was just an ordinary medical ninja.

Shimizu, who had walked away, had no idea what Shizune was thinking.

Even if he knew, he wouldn't care.

Right now, he was merely slacking off, not even using his full potential.

If he focused, his efficiency could double.

Through his research, he had uncovered some secrets of the Moryō's power.

However, he dared not use it here. If his healing speed became too monstrous, he would become the target of countless eyes.

Medical ninjutsu was critical in war.

If medical support couldn't keep up, wounded ninjas would become expendable.

They would either die from their injuries or perish on the battlefield due to a lack of reinforcements.

If news of Moryō's power spread, Konoha's higher-ups would surely force him to hand it over.

Others might also coerce him into giving up his secrets for the so-called 'greater good.'

But the Moryō's power was finite. Once used up, it was gone. There was no way Shimizu would let that happen.

He popped a military ration pill into his mouth to recover some stamina.

Then, he slipped into a supply tent and activated his simulator.
