Awakening Of Uchiha [Naruto/One Piece]

Chapter 30: Uchiha Katsumi Recovers

______

On Katsumi's side, as time passed, his body grew stronger day by day.

The essence of his life was nourished by medicine and Sea King meat. Combined with health-preserving exercises, his recovery accelerated significantly. Even his height increased once again.

Four days later, Kureha successfully created super-nutrition potions and body-building potions.

It took Katsumi only two days to develop weakened versions of these potions with varying effects, such as one-tenth, two-tenths, five-tenths, and eight-tenths of the original strength.

In addition, he created nutrition pills by combining Sea King meat with various medicinal ingredients. Weakened pills of varying levels, ranging from 10% to 90% potency, were also developed.

After another seven days, he successfully weakened the conditioning potion used for healing hidden injuries and restoring vitality. Building on that foundation, he combined the nutrition pills and potions to create a mild yet highly effective potion capable of replenishing a large amount of vitality in a short time.

Katsumi named this new creation the Life Potion.

"Hmm, this potion should perfectly solve Mito's problem," Katsumi mused as he examined the bottle of Life Potion, radiating gentle vitality, in his hand.

"The premise, of course, is that her issue is truly just excessive loss of vitality."

By now, after years of study and research, Katsumi's medical skills had reached the small success level, and he had made significant progress even within this level. His achievements in other areas had also advanced greatly.

"Oh? The potion you've made isn't bad," Kureha remarked as she approached, her eyes on the Life Potion in Katsumi's hand. "Especially for ninjas like you who extract cellular energy—it's quite suitable! With this, you've essentially solved the issue of burning your own life force for power."

"But I imagine it's not cheap to produce, right?" she asked with a smile.

"Hmm!" Katsumi nodded firmly. "It's indeed not cheap. It requires a substantial amount of Sea King meat and rare medicinal ingredients. The extraction and refinement process is particularly cumbersome and difficult. If converted into Belly, the cost comes to about 5 million per bottle!"

He paused, then continued, "If the extraction and production processes can be improved in the future, the cost will definitely decrease significantly. But that's not something that can be achieved in the short term."

For now, he lacked expertise in mechanical manufacturing and technological development, making it impossible to optimize the process or build an advanced production line.

"Maybe I could establish a partnership with Orochimaru?" Katsumi thought to himself.

But he quickly dismissed the idea. "No. His current scientific research capabilities aren't strong enough. Moreover, he's still a staunch supporter of the Third Hokage at this stage, making him unsuitable."

"Perhaps I should look to the pirate world for solutions," he considered. "For example, obtaining technology from Germa 66?"

However, he knew his current strength wasn't enough to pull this off. It was evident he would have to rely on his mother for now.

"Mom already has enough on her plate! The Life Potion isn't an urgent priority. It can wait," Katsumi sighed inwardly.

Oh, how I lack a trustworthy and powerful ally!

Fortunately, he didn't currently need the Life Potion himself. Once his recovery was complete, the nutritional potions and pills would be more than sufficient to replenish his vitality and energy.

"This is already very impressive," Kureha remarked with a shake of her head. "The more potent the potion, the harder it is to refine. You know this."

"You'll be fully recovered in a few more days. But don't forget the large collection of medical books you promised me. Will you be visiting often in the future?"

At present, Kureha had received less than 200 medical books from Katsumi. It was still a long way from what she had been promised, but even this modest collection had greatly benefited her.

"Of course!"

Katsumi smiled and nodded. "Don't worry! Even after I recover, with my current strength, it's not yet time for me to set out to sea and explore. Besides, I still have thousands of medical books here that I haven't finished reading, and I haven't fully learned your medical skills. How could I give up and not come back?"

I need to squeeze every bit of value out of Kureha.

He even hoped to raise Kureha's favorability toward him to over 80 points.

Currently, her favorability had risen to 72 points—victory was within reach! However, he knew that the higher the favorability, the slower it would increase. It would likely take him a few more months. Thankfully, frequent exchanges of medical knowledge and regular interaction would help him achieve his goal, albeit gradually.

"Haha!"

Kureha burst into laughter, pointing at Katsumi. "You're such a greedy kid! Learning my medical skills won't be easy. Be prepared to stay here for a long time!"

With that, she turned around, heading back to her recliner to continue reading her medical books.

In the blink of an eye, several days passed.

Katsumi had now been on Drum Island for almost a month.

Today, his body had finally fully healed.

The innate deficiencies in his life force had been completely repaired.

In fact, thanks to the health-preserving exercises he had practiced during this time, and the feedback from his fully restored vitality, his life force now far surpassed that of the average person. His physique was several times stronger than that of his peers in the ninja world.

"Haha! I'm finally recovered! My lifespan has exceeded 95 years. If I continue practicing Health Preservation, I might break 100 years soon," Katsumi exclaimed, feeling relieved and deeply satisfied.

He had worked tirelessly over the past month to regain his health, and now his efforts had paid off.

"Next, I can finally start formally practicing Chakra, Ninjutsu, Taijutsu, and even Six Styles and Haki!"

Of course, he knew these would need to be developed gradually. For techniques like the Six Styles and Haki, he would need to carefully plan his training based on his body's limits, taking it one step at a time.

Even with nutritional pills and potions to replenish his vitality and nutrients, Chakra training had to be carefully controlled to avoid overexertion.

"Huh? I've awakened the Yang attribute? That's a pleasant surprise!" Katsumi mused.

"This will make learning medical ninjutsu and Yang Release much easier! It's probably related to my recent consumption of large quantities of Sea King meat, which replenished my vitality, improved my physical fitness, and enhanced my life force."

The discovery brought him joy.

"The only thing missing is the lightning attribute to achieve all five elements. Maybe I can obtain it by eating a Thunder Fruit?"

He couldn't help but imagine the possibilities.

However, he quickly hesitated. Should I really eat a Devil Fruit and gain such a major weakness?

While seawater in the ninja world wouldn't trigger the fruit's weakness, the seawater in the pirate world certainly would. Since he planned to dominate the pirate world in the future, this vulnerability couldn't be overlooked.

"I wonder if there's a way to eliminate that weakness?" he pondered aloud.

Unable to think of a solution, Katsumi decided to set the idea aside for now.

After bidding farewell to Mikoto and Kureha, he used teleportation to return home to the ninja world.
