On Genqing's side—
As time passed, his body grew stronger by the day.
With the nourishment of medicine and Sea King meat, combined with the healing effects of the Health-Nurturing Art, his life essence recovered at an astonishing rate.
Even his height was shooting up again.
Four days later, Kureha finally completed the creation of super nutrition serums and body-strengthening tonics.
It only took two days for Genqing to then develop various weakened versions of them—
Including 10%, 20%, 50%, and 80% effectiveness variants.
He also created nutritional pills by combining Sea King meat with specialized herbs—
And followed up with weakened versions ranging from 10% to 90% potency.
Another seven days later,
He succeeded in weakening the restorative medicinal formula used to treat internal injuries and recover vitality.
Building on that, and blending it with the nutritional pill and serum, he finally created a gentle yet powerful tonic capable of rapidly replenishing life force.
He named it: Life Elixir.
"This should be enough to solve Uzumaki Mito's problem—"
"As long as her issue really is just life force depletion."
Genqing studied the softly glowing liquid in his hand, satisfied.
By now, his medical skills had advanced significantly—
He had officially reached the proficient level, and was progressing steadily within it.
Other abilities had also grown by leaps and bounds.
Just then, Kureha walked over, examining the tonic in his hand with a grin.
"Not bad, kid. Especially useful for you chakra-extracting types."
"With this, you've basically removed the downside of burning through your own life to use powerful techniques."
"But I assume this thing isn't cheap?"
"Mm."
Genqing nodded.
"Not at all. It requires a large amount of Sea King meat and rare herbs."
"The extraction and refinement process is also extremely complex and time-consuming."
"Cost-wise, it's about 5 million Berries per vial."
"I could reduce that if I find ways to improve the production process and automate parts of it—"
"But that'll take time."
Mechanical design and industrial engineering weren't his strengths yet.
"Maybe… I could work with Orochimaru?"
But then he shook his head:
"No. Not yet. Orochimaru's current level in research is lacking."
"Plus, he's still fully loyal to the Third Hokage—he's not reliable."
"Maybe I can get some tech from the Germa 66 side in the pirate world instead?"
Still, with his current strength, that wasn't realistic.
"Guess I'll have to ask Mom again."
"Ugh… but she already has so much on her plate."
"And the life elixir isn't urgently needed right now."
"I really need a reliable, strong follower…"
Genqing sighed in frustration.
Luckily, he himself didn't need the elixir anymore.
As long as he had the basic nutritional supplements, he could maintain his health and training safely.
"Still, this is a great achievement."
Kureha nodded in approval.
"The stronger the medicine, the harder it is to make. You know this."
"You're almost fully recovered. But don't forget—you're still behind on the medical texts you promised me!"
"You'll be visiting often, right?"
So far, she had only received around 200 medical books from him.
There was still a long way to go.
But even from those, she had already learned a ton.
"Of course!"
Genqing smiled.
"Even if I'm healthy now, I'm not ready to wander the seas yet."
"Besides, I still have thousands of your medical books to study—and I haven't finished learning all of your techniques either."
"No way I'd give that up!"
He definitely planned to squeeze every last drop of value from Kureha.
He was also aiming to push her affection rating above 80.
It was already at 72 points—he was close!
As long as he kept spending time with her and discussing medicine, it was bound to increase.
"Haha!"
Kureha burst out laughing.
"You greedy little rascal. Learning all my secrets won't be easy!"
"Better prepare to stay here long-term!"
She turned and went back to her lounge chair, cracking open another medical book.
A few more days passed.
By now, Genqing had been on Drum Island for nearly a month.
Today, his body was fully healed.
His congenital life essence deficiency was completely repaired.
In fact, thanks to his intense cultivation and the restorative backlash from filling the void, his life essence was now far higher than normal.
His body far surpassed any peer from the ninja world.
[Uchiha Genqing]
Talent: Gate of Space-Time, Heaven Rewards Diligence
Lifespan: 95 years, 7 months, 19 days (Life Essence: 13.2)
Chakra Attributes: Water, Wind, Fire, Earth, Yin, Yang
Skills:
Uchiha Chakra Refinement (1/100 – Beginner)
Medical Arts (7,568/50,000 – Proficient)
Health-Nurturing Technique (5,145/10,000 – Advanced)
Uchiha Meditation (456/1,000 – Skilled)
Basic Taijutsu (342/500 – Adept)
"Yes! Finally healed! My lifespan's up to 95 years—and if I keep training Health-Nurturing Arts, hitting 100 shouldn't take long!"
Genqing was thrilled to see his progress.
He had worked incredibly hard over the past month to get here.
"Now I can start training chakra, ninjutsu, taijutsu, and eventually the Rokushiki and Haki!"
Though those would need to be approached gradually, especially Haki and Rokushiki, which placed heavy demands on the body.
Even with his nutritional boosts, chakra training had to be carefully paced to avoid harming himself again.
"Oh? I've awakened the Yang attribute too?"
"Nice surprise! That'll make training healing ninjutsu and Yang Release a lot easier."
"Must be from eating all that Sea King meat and rebuilding my life essence."
Genqing made a mental note.
"Now I'm just missing Lightning to be a full elemental user. Maybe eating the Goro Goro no Mi (Lightning Fruit) would do it?"
But he hesitated.
Eating a Devil Fruit meant taking on a serious weakness.
While chakra-infused water didn't harm Devil Fruit users, pirate-world seawater still did—and he planned to dominate that world eventually.
"Is there a way to remove that weakness?"
"Guess I'll have to investigate that later."
For now, he shelved the thought.
He called for Mikoto, bid Kureha farewell, and the two teleported back to their home in the ninja world.
