Chapter 30: The Healing of Gin — The Medicine of Life

During this time, Uchiha Gin's body continued to recover steadily. His vitality was being restored thanks to specially formulated medicines and the potent flesh of the Sea Kings. Combined with daily taijutsu-based health exercises, his physical condition improved rapidly—even his growth spurts returned.

Four days into the recovery, Kuraha had finally developed a set of super-nutritious and strengthening compounds. Using her formulas, Gin began experimenting, developing diluted variants that delivered effects ranging from 10% to 80% of the original potency.

Soon, he also produced nutrient pills from Sea King meat, further enhanced by synthesized drugs—some boasting 90% efficiency in restoring chakra and cellular energy.

Seven days later, Gin achieved another breakthrough: medicines that could heal hidden injuries and restore deeply rooted vitality damage. By combining them with his nutrient pills, he created a revolutionary formula—one that rapidly replenished life force. He named it:

"The Medicine of Life."

"Hm," Gin mused, holding a glowing vial of pale blue liquid, its energy pulsing faintly. "This might be the perfect solution for Lady Mito. Her vitality loss is extreme... but this—this could bring her back."

By now, his medical skill had reached small success. Not just in theory, but in practical application. His overall ability across various domains had improved substantially.

"Well, well," Kuraha said, stepping into the lab with a teasing grin. "Not bad! This medicine is especially suited for high-level shinobi who burn life force using forbidden jutsu or intense taijutsu. You've nearly solved the problem of cellular fatigue. But it can't be cheap to produce, can it?"

"Hmph," Gin exhaled, rubbing the bridge of his nose. "It's very expensive, actually. The extraction process is ridiculously complex and energy-intensive. If we priced it in Berries... probably 5 million per bottle. With mass production, the cost could drop, but I don't have the equipment or infrastructure for that yet."

He paused, considering a risky thought.

"Should I try to cooperate with Orochimaru? His scientific knowledge might help mass-produce these drugs..."

But Gin quickly dismissed the idea.

"No. He's still aligned with the Third Hokage. Too dangerous. Too unpredictable."

Another thought crossed his mind.

"Perhaps Jerma 66 could offer biotech support? But I'm not strong enough to make contact. I'll need Mother's help... again."

He sighed inwardly.

"Poor Mom—already burdened with so much. The Medicine of Life can wait for now. First, I need a reliable and powerful assistant."

Fortunately, Gin didn't need the medicine himself. His body had nearly returned to full power, and for everyday exertion, his existing nutrient pills were more than enough.

"This is already impressive work," Kuraha said, genuinely impressed. "The more potent the medicine, the harder it is to make it stable. You're almost fully recovered. But I still expect you to keep your end of the bargain—those medical texts you promised me!"

Gin chuckled. "Of course! Don't worry. Even when I'm fully healed, I won't be heading back to sea just yet. I still have a thousand of your medical books to read and plenty to learn. I'd be a fool to leave now."

"I have to get the most out of Kuraha before leaving," he thought slyly. "Her favorability is at 72. Just a little more... If I can get above 80, I'll earn access to her restricted techniques. That will take a few more months, even if the rate slows down. But steady interaction and medical exchanges should raise it naturally."

"Haha! You're a greedy one!" Kuraha laughed. "But if you think my skills come easy, you better settle in for a long stay!"

She returned to her chair, flipping open a thick leather-bound tome on complex herbal reconstruction formulas.

Ten Days Later — End of Recovery

Time flew.

Gin had spent nearly a month on Drum Island. His body was now completely restored.

The source of his life force—once critically deficient—had not only recovered but grown exponentially stronger. The constant exercise, medicinal feedback, and spiritual cleansing made him physically far superior to most shinobi of his age.

[Name]: Uchiha Gin[Bloodline Talent]: Gate of Space-Time, "God Rewards the Diligent"[Lifespan]: 95 years, 7 months, 19 days[Source of Life]: 13.2[Chakra Affinities]: Water, Wind, Fire, Earth, Yin, Yang[Skill Progress]:

Cleansing Method of the Uchiha: Entry (1/100)

Traditional Eastern Medicine: Small Success (7568/50,000)

Health Maintenance Exercises: Great Success (51,545/10,000)

Uchiha Meditation: Grandmaster (456/1,000)

Basic Physical Skills: Professional (342/500)

"Haha! I've finally recovered!" Gin laughed aloud, his fingers flickering with a clean flow of chakra. "Even my lifespan's surpassed 95 years. If I keep doing health exercises, I might hit 100!"

Over the course of the month, Gin had rebuilt himself from the inside out.

Now, he could properly begin training in chakra manipulation, ninjutsu, taijutsu, the Rokushiki techniques, and even Haki. Each needed time and planning. Especially Haki and Rokushiki, which required extreme physical and spiritual control.

"I must be careful not to overstrain my chakra purification. Even with nutrient pills, there's a daily limit."

Then he noticed something strange in his chakra flow.

"Huh? I awakened the Yang attribute?"

He smiled, surprised.

"This will make learning medical ninjutsu and Yang-style techniques much easier! Probably the effect of Sea King meat—boosted my vitality and life force so much, it triggered the awakening."

Now only one affinity eluded him.

"If I had the Lightning attribute... I could complete the set. Perhaps if I eat the Goro Goro no Mi?"

But doubt clouded his face.

"Will the Devil Fruit curse affect me? In the Naruto World, seawater doesn't have that effect. But in the One Piece world, it does... and that's where I plan to rule someday. I can't risk that weakness."

Gin sighed.

"Maybe someday I'll find a way to eliminate that vulnerability. But for now… I'll wait."

And so, after bidding farewell to Kuraha and Mikoto, Gin activated his teleportation technique.

With a single pulse of chakra, the space around him warped.

In a blink, Uchiha Gin returned to the Ninja World.
