Naruto: You Call This A Medical Ninja?

As Senju Hashirama and Uchiha Madara disappeared, the atmosphere remained heavy. Reiki stood silently, watching the spot where the two legends had vanished.

It was their choice.

"Teacher…" Reiki broke the silence, his voice calm despite his visible grief.

"I'm fine," Tsunade interrupted before Reiki could respond. "My grandfather was always someone who lived freely. If this was his decision, I respect it." She turned to Reiki, forcing a faint smile. "If you know anything else about what's coming, tell me."

Reiki nodded. "I will."

At that moment, Orochimaru approached, his expression unreadable.

"The coordinates have been sealed," he said. "And Otsutsuki Ishiki has been banished by the Shodaime and Madara-sama. Is it over now?"

Reiki shook his head. "Not quite… When Otsutsuki Ishiki activated the coordinates, it sent a signal to Takamagahara. Even though the coordinates were sealed, they now know the ninja world exists."

Tsunade frowned. "Then you're saying…"

"Yes," Reiki said firmly. "The Otsutsuki clan will come. It's no longer a matter of if, but when. That's why we need to be prepared—and why the Ninja Alliance was formed."

Tsunade sighed, her resolve wavering for a moment. "If we're not ready to face the entire Otsutsuki clan, we'll need more than just strength…"

"We'll need unity," Reiki said, finishing her thought. "And a new generation of guardians. It could be you, Lord Orochimaru... or even me."

Tsunade was taken aback by the warmth and confidence in his expression. "Alright," she said finally. "I'll leave it to you." With that, she turned and walked away.

As she left, Hatake Sakumo and others, including trainees and instructors, arrived. The lingering aura of the battlefield overwhelmed the younger shinobi, many of whom collapsed, trembling with fear.

"Reiki…" Sakumo stepped forward but was cut off by Reiki's calm voice.

"Stay here. Let them feel this battlefield," Reiki said. "Let them understand what they will face in the future."

Raising the Sky-Shattering Blade, Reiki slashed the air, creating a dimensional crack. Without another word, he stepped into it and disappeared.

Hatake Sakumo turned to the shaken group. His eyes hardened as he addressed them.

"Are you scared?!" he shouted, his voice startling everyone, including Orochimaru. "If this battlefield terrifies you, go back to your villages. If you cannot overcome this fear, you are unworthy of carrying your village's expectations!"

The young shinobi looked at him in stunned silence.

"For the strong, fear isn't a hindrance—it's a motivator!" Sakumo continued. "Instead of being paralyzed, learn from this. Feel the willpower and determination that drove this fight!"

With those words, he sat down cross-legged, closing his eyes in meditation. The battle had left him with much to reflect on.

The trainees and instructors, though still shaken, began to process his words. Slowly, they sat down as well, choosing to face their fears head-on.

Reiki emerged in a desolate, barren world. Before him stood a massive, ancient tree stump, its roots spreading across the lifeless ground.

"So, this is the world you controlled?" Reiki said, his voice calm but curious.

The tree stump vibrated in response. This was the world once ruled by Otsutsuki Ishiki, a world sustained by the Chakra Sacred Tree.

"This belongs to you, doesn't it?" Reiki raised his hand, revealing a glowing sphere of energy—the original core of the Ten-Tails, captured from Ishiki.

The tree roots surged forward as if responding to the presence of the core. Reiki injected the energy into the stump.

[Ding! Simple treatment of the Chakra Sacred Tree rewards you with eternal power and healing points…]

The system's notification echoed in his mind as a surge of energy flooded his body. Reiki's height increased slightly, and his life force transformed, radiating with a newfound vitality.

"Eternal power…" Reiki murmured. "Is this what the Otsutsuki clan has been chasing all along?"

The once-dead tree stump began to sprout new branches and leaves. The barren world seemed to shrink and shift, revealing a vibrant pulse of life.

"This…" Reiki's eyes widened in surprise as he witnessed the world slowly rejuvenating.

The Chakra Sacred Tree, now fully restored, materialized before him in its spiritual form.

"This world has recognized you," it said in a voice both ancient and intimate. "From this moment, you are the master of this world."

Reiki stood in awe as the once-dead land began to teem with life. The realization struck him—he wasn't just a ninja anymore. He was now a lord of this world, entrusted with the power to shape its destiny.
