Naruto: You Call This A Medical Ninja?

During his rigorous training, Reiki hadn't slept for days.

Even someone as resilient as him couldn't hold on forever.

As for the other ninjas, they had already collapsed from exhaustion.

Everyone understood the importance of balance, so after a period of intense practice, rest breaks were mandatory.

With the arrival of Uchiha Madara and Senju Hashirama, the special training camp took on a new dynamic.

Not only were the young ninjas participating in actual combat training, but even instructors like Hatake Sakumo found themselves drawn into the fray.

And who were their trainers? Naturally, Uchiha Madara and Senju Hashirama themselves.

Evening.

"Brother Reiki, Lord Orochimaru is here," Shizune's voice called out as Reiki was preparing potions.

"Lord Orochimaru? What's going on? There aren't any training missions today, right?" Reiki asked with a smile as he stood up.

Deep down, Reiki had expected Orochimaru to approach him sooner or later.

There was something wrong with Orochimaru's body—it had changed somehow, as if he were no longer the same person.

"You noticed, didn't you?" Orochimaru said as he entered.

"My body… is no longer mine."

Orochimaru's tone was uncharacteristically helpless.

"But this body…" Reiki hesitated, staring at him.

It wasn't the typical result of Living Corpse Reincarnation. Instead, it felt… unnatural.

"This body was cultivated using my own cells," Orochimaru explained.

"There's no rejection or backlash. Additionally, I infused it with Yin-Yang Release."

Reiki's eyes narrowed as he began to understand.

Orochimaru's new body was indeed suited for him, allowing reincarnation without harming others.

However, the integration of Yin-Yang Release had created an unintended side effect—an additional consciousness had emerged within the body.

Two wills now inhabited Orochimaru's form, creating the strange dissonance Reiki had sensed.

"Do you want me to remove the Yin-Yang Release or help you integrate it with your body?" Reiki asked directly.

"I need you to teach me how to master Yin-Yang Release," Orochimaru replied quickly.

Reiki fell silent for a moment, weighing the options.

It was clear that simply removing the Yin-Yang Release wasn't a long-term solution.

Mastering its power would be far more beneficial.

"Fusion isn't something I can help with," Reiki finally admitted.

"But Black Zetsu has experience with Yin-Yang Release. Alternatively, if we could find a member of the Ōtsutsuki clan—"

Before Reiki could finish, Orochimaru suddenly lunged at him.

"You'll do just fine as a container!" Orochimaru's hand closed around Reiki's neck, his voice suddenly different.

It wasn't Orochimaru speaking anymore.

"You already possess Yin-Yang Release in your body. There's no need for further complications!"

Reiki's breathing stopped as the grip tightened around his throat.

At the same time, a surge of Yin-Yang energy spread from Orochimaru's hand, sealing Reiki's chakra and immobilizing him completely.

The surrounding space distorted as barriers rose, isolating them.

"Why can't my bond take hold in your body?!"

For the first time, a flicker of panic crossed Orochimaru's face—or rather, the face of the entity controlling him.

He released Reiki and staggered back.

A chilling realization dawned on the intruder: something terrifying resided within Reiki's body.

Even minimal contact had almost overwhelmed him.

"Bond? Wait… Are you Ōtsutsuki Ishiki?!" Reiki gasped, finally piecing it together.

The voice was unmistakable—it belonged to Ishiki, the Ōtsutsuki who had supposedly been killed by Madara and Hashirama.

But how could Ishiki have taken over Orochimaru's body?

Even stranger, why hadn't he targeted Madara or Hashirama instead?

"Ah, so you recognize me," Ishiki said mockingly.

"Your talent and fortune are remarkable, but so what? Even knowing who I am, what can you do?

"You can't harm this body, and you certainly can't kill me."

Reiki stared at Ishiki, his mind racing.

On his system panel, Orochimaru's name now glowed with a golden hue.

It was a color he had only seen once before, though he couldn't remember where.

For now, it wasn't important. What mattered was dealing with Ishiki.

"Madara and Hashirama are here in the camp," Reiki said, forcing himself to stay calm.

"If I make a sound, they'll be here in an instant. Do you really think they can't kill you in this body?"

Reiki's words were calculated, probing Ishiki's plans.

Ishiki wasn't the type to act recklessly—he always had contingencies in place.

Why reveal himself now, especially in such a vulnerable state?

"You're trying to test me, aren't you?" Ishiki sneered.

"You're clever, Reiki, but it won't save you. Even if I can't possess your body, I'll take you with me!"

Ishiki raised his hand, and a crack appeared in the air behind him.

Tree roots began emerging from the rift, wrapping around Reiki's body.

"This… This is the Chakra Divine Tree's roots!" Reiki exclaimed, his eyes widening in shock.

The roots carried a familiar yet oppressive energy—the essence of the Divine Tree.

When had Ishiki planted one?

[Ding! A special injury has been detected: Chakra Divine Tree.]

Reiki froze as the system notification appeared.

Injury? Could the Divine Tree really be classified as an injury?

For a moment, Reiki was stunned.

But if it was labeled an injury…

"That makes things easier," Reiki muttered, his eyes narrowing.

"Holy Hand Domain!"

Reiki raised his hand, and his domain exploded outward, shattering the barriers Ishiki had created.

The roots of the Divine Tree began to wither as Reiki's power surged, filling the space.

"You!" Ishiki growled, his composure slipping for the first time.

Reiki smirked, his confidence returning.

"If you want to fight, Ishiki, let's see who comes out on top."
