3. The Hope Of Extending Life, The First Journey Into The World Of One Piece

"It's good that it's useful!" 

Uchiha Sora felt a wave of relief after hearing his mother's affirmation. He smiled warmly and said, "This way, both Mom and I can continue to live!" 

"Also, Mom, haven't I gained a lot of knowledge and experience in medicine and herbal remedies?" 

"Let me examine your condition. Based on what I find, I'll prescribe some treatments to help regulate your body and speed up your recovery!" 

"Of course, I'll need it too!" 

If Uchiha Mikasa's health could be improved and her lifespan extended, it would make the challenges ahead much more manageable. 

"Oh?" 

Uchiha Mikasa raised her eyebrows slightly. "Even medical knowledge and herbal expertise are included? This sage inheritance is quite comprehensive!" 

"In that case, Sora, go ahead and check my condition first." 

"As for the medicinal materials, leave that to me. Our family isn't short on money." 

"Yes!" 

Sora nodded and immediately began to examine his mother's body. 

After a thorough check, his expression turned grim. Pulling his hand back from her wrist, he said solemnly, "The situation is worse than I thought." 

"In addition to various hidden injuries, your cells have been continuously extracting chakra over the years. This has severely depleted their vitality and division, drastically affecting your lifespan." 

"But that's not the most critical issue..." 

Sora raised his head, his eyes focusing on his mother's right eye, which had a dull white pupil. His expression grew darker. 

"The real issue is that you used Izanami. Not only did it leave your right eye permanently blind, but it also consumed a significant portion of your life source and soul source." 

"This is the real threat to your health." 

Sora's voice carried both concern and frustration. He had assumed the cost of the Forbidden Technique was merely blindness, but it was far more severe. 

Uchiha Mikasa noticed his troubled expression and smiled faintly. 

"I didn't expect the medical inheritance you received to be so advanced that it could reveal these hidden issues." 

"And you even know about Izanami," she added with a hint of amusement. 

"It seems your knowledge of the two worlds isn't as superficial as you initially claimed." 

She leaned back slightly and continued, "However, your conclusion isn't entirely accurate." 

"Izanami itself wasn't the primary reason for the loss of my life source and soul source." 

"Once perfected, and when mastered and used properly, Izanami does not have such side effects. The cost is truly just the loss of a Sharingan." 

"But when I first developed this technique, it wasn't perfected. I created it on my own to address internal strife within the Uchiha clan." 

"It's only natural that there were failures during its development." 

She sighed softly. "The abnormal depletion of my life and soul sources occurred during the creation process, not from using the perfected technique." 

Sora listened intently, his expression softening as he gained a clearer understanding. He nodded and gave his mother a thumbs-up. 

"Mom, you're incredible! Developing such a heaven-defying technique on your own is amazing!" 

"However," he added with a frown, "if you want to restore your lost life, simply treating your body and healing hidden injuries won't be enough. You'll need to restore your depleted life source and soul source as well."

'Isn't the congenital deficiency of the body essentially a congenital lack of life source?'

'And with the medical knowledge I currently have, there's no way to restore it.'

'Maybe we'll have to travel to the One Piece world through the space-time gate to find a solution.'

Uchiha Sora's thoughts were clear, but he also knew another option existed. If he could use his talent, God Rewards Hard Work, to improve his Chinese medicine skills to Minor Success or even Great Success, he might find a solution.

However, that would require significant time.

While he could wait with the support of his health-preserving exercises and his talent, his mother might not have the same luxury.

Moreover, the ninja world was far too dangerous. Their immediate priority was to heal themselves, extend their lifespans, and improve their strength as quickly as possible.

Time was of the essence.

"Oh?"

Uchiha Mikasa raised an eyebrow, a flicker of surprise crossing her face. "Are there truly doctors in that world capable of addressing our physical issues?"

"If so, that's wonderful."

"I think so!"

Uchiha Sora nodded, though not with absolute certainty. "That world is also quite magical..."

He proceeded to give Uchiha Mikasa a general overview of the One Piece world's worldview, the concept of Devil Fruits, and other extraordinary phenomena.

He concluded, "Among the Devil Fruits, ones like the Heal-Heal Fruit and Horm-Horm Fruit could potentially solve our problems."

"Of course, those won't be easy to find. But there's another option: going to Drum Island to seek out the witch, Dr. Kureha."

"She is said to possess exceptional medical skills and may even know the secret to a longevity medicine."

"Even if she can't cure us completely, she should be able to significantly improve our conditions and extend our lifespans, buying us time to search for a more permanent solution."

"The best part is that she's relatively easy to locate."

Uchiha Sora turned to his mother, his gaze determined. "So, Mom, let's make time to travel to the pirate world soon and find Dr. Kureha. She may be our best hope!"

"Okay," Uchiha Mikasa agreed after a moment of thought.

She then asked, "How long do you think it will take to reach her? I'll need to make arrangements for the clan beforehand."

"Uh..."

Sora hesitated, scratching his head. "I don't know yet. I'm not even sure where we'll end up when we first arrive. How about we go there together to get our bearings, then come back to plan further?"

'Hopefully, the plot hasn't started yet,' Sora thought inwardly, knowing it would greatly affect their plans.

"Alright," Mikasa said without hesitation. "I'm free today. Let's go now! Is there anything we need to prepare?"

"No," Sora replied. "We can return anytime, so there's no need to bring anything extra. But I can't guarantee the location we arrive at will be safe, so please stay on alert, Mom."

"Leave it to me!" Uchiha Mikasa smiled confidently, clenching her fist. "Your mom is very strong!"

"Yeah!"

Sora smiled and nodded. He reached out, holding one of his mother's hands. With a thought, he activated the space-time gate rune in his sea of consciousness.

In the next instant, he and Uchiha Mikasa vanished from their home.

One Piece World, Grand Line, between the Seven Waters and Sabaody Archipelago

At this moment, two pirate crews were locked in fierce battle.

One side was the fleet of the Kuja Pirates, while the other was the Crazy Shark Slave Group, infamous for their involvement in the slave trade.

"Bring the ship closer! Capture them! The female warriors of Amazon Lily are top-tier merchandise and will fetch a fortune!"

"Kahahaha! Leave it to us, Boss!"

"Kill them!"

The clash raged on, but within a mere ten minutes, the Kuja Pirates found themselves at a severe disadvantage.

Forced back by the overwhelming might of the Crazy Shark Slave Group, the enemy boarded their ship.

"Sister, what should we do? Everyone is in danger!" Sandersonia cried, her face pale with fear as she hid behind her elder sister.

"Yes, Sister! What do we do? Should we step in?" Marigold asked anxiously, her voice trembling.
