Naruto: You Call This A Medical Ninja?

After carefully processing Orochimaru's words, Reiki fell silent. The implications of what Orochimaru had discovered were significant.

Indeed, ensuring Orochimaru could master Sage Mode would undoubtedly elevate his strength. However, when compared to the potential of Yin-Yang Chakra, even a weaker Orochimaru—one who lacked proficiency in ninjutsu—seemed less pressing.

For now, Reiki's primary concern remained Tsunade. The ninja world currently lacked awareness of the transformative potential of Yin-Yang Chakra. Perhaps this was something he could explain to her in due time.

Turning to Orochimaru, Reiki finally spoke. "Lord Orochimaru, I understand what you're aiming for. Very well, proceed as you wish. However, your physical condition must be monitored carefully."

Reiki continued, "Here's my suggestion: contact the Sanada Chamber of Commerce for any experimental materials you need. I'll personally check your condition daily to ensure you can manage both your research and your recovery. Does that work for you?"

Orochimaru nodded. "That's fine with me. But first..." He gestured toward Jiraiya, who lay twitching on the ground. "Perhaps you should check on Jiraiya before he dies."

Reiki turned sharply, realizing he'd been so engrossed in the conversation that he had forgotten about the injured Jiraiya. He rushed over to heal him.

Jiraiya, now stable but glaring at the two of them, groaned, "You two... next time, could you discuss your experiments after treating me?"

Ignoring Jiraiya's complaints, Reiki turned back to Orochimaru. "So, what's this chakra you're talking about?"

Orochimaru smirked, clearly enjoying the attention. "Yin-Yang Chakra," he said. "It's a special form of chakra, similar in concept to elemental chakra like Fire Release or Lightning Release, but fundamentally different in nature."

Reiki elaborated for Jiraiya, "For instance, the Nara clan's shadow techniques are a manifestation of Yin Release chakra. However, their use is incomplete. What Orochimaru-sama has developed is the complete form—Yin-Yang Chakra. Its applications are vast, and personally, I see immense value in it."

Intrigued, Jiraiya sat up straighter despite his injuries. "Orochimaru, do you have a finished sample? I want to see what makes this so special."

Orochimaru grinned and pulled out a test tube containing a glowing orb of energy. "It's not the final product, but it's functional. Here, give it a try."

Jiraiya hesitated briefly before taking the test tube and opening it. Orochimaru instructed, "Channel your chakra into it—preferably one of your elemental chakras. You'll understand soon enough."

Curious, Jiraiya formed a seal and channeled his Fire Release chakra. The Yin-Yang Chakra in the test tube immediately became agitated before surging into Jiraiya's body.

Orochimaru observed with satisfaction. "Now release a jutsu quickly. Your body won't tolerate the erosion of the Yin-Yang Chakra for long."

"You could've warned me earlier!" Jiraiya grumbled before weaving seals. "Fire Release: Fire Dragon Jutsu!"

What emerged wasn't the usual B-rank jutsu. Instead, a monstrous fire dragon erupted, roaring with immense power. The flames burned with such intensity that the earth beneath them melted into molten lava.

Jiraiya stared in awe as the fiery dragon dissipated. Where it had struck, the ground was transformed—a massive lava-filled trench stretched ten meters wide and three meters deep. The residual heat warped the air around it.

Moments later, the ninjas and instructors from the special training camp rushed over, drawn by the overwhelming energy.

"Are we under attack?" Ai asked in alarm, surveying the devastation. The magnitude of the Fire Release was beyond anything he had encountered. Even his Lightning Armor wouldn't withstand such destructive power.

Kirabi, too, was stunned. "This...this kind of Fire Release... Jiraiya-sama, was this your doing?"

Jiraiya scratched his head sheepishly. "Uh... yeah, that was me. Sorry for the commotion."

Reiki quickly stepped forward, weaving a hand sign. "Water Release: Heavenly Breakthrough!" A torrent of water poured out, dousing the molten lava and quelling the lingering heat.

As the steam cleared, Kirabi's jaw dropped. "Reiki, you know Water Release?! Aren't you supposed to be a medical ninja?"

Reiki raised an eyebrow. "What's surprising about that?"

Kirabi gestured animatedly. "You're not just a medical ninja—you've got insane physical skills, space-time techniques, and now ninjutsu?! And that water jutsu... you didn't even form proper seals! That's easily S-rank!"

Reiki chuckled. "Well, I aim to be versatile."

Meanwhile, the Kirigakure ninjas present looked thoroughly demoralized. They had trained for years to master Water Release, yet Reiki's casual display outclassed their most advanced techniques. It was a blow to their pride.

Kirabi glanced at the dejected Mist ninjas and smirked. "Man, you guys look like you just saw your whole career flash before your eyes."

Reiki, unfazed, turned back to Jiraiya. "So, Jiraiya-sama, do you now understand the potential of Yin-Yang Chakra?"

Jiraiya nodded, still in awe. "Yeah... I've never seen anything like it. Orochimaru, this is incredible. I can't imagine the possibilities if this is just the beginning."

Reiki smiled. "Exactly. Now, let's make sure to explore it responsibly. Orochimaru, your discovery is revolutionary—but let's not forget to keep things in balance."

Orochimaru gave a sly grin. "Of course, Reiki. Balance is key... until it isn't."

Reiki sighed. This was going to be an interesting journey.
