In the 29th year of Konoha, in a room within a large courtyard of the Uchiha clan, "Swish!"
A six-year-old, thin boy named Ethan Uchiha suddenly opened his eyes and sat up straight as he successfully extracted the first trace of chakra.
"This is..."
At that moment, a flood of familiar and unfamiliar memories surged into his mind.
After a while, he fully digested the memories that kept emerging, then looked around with astonishment, muttering in his heart:
"Have I travelled through time? I didn't expect to awaken the memories of my past life only now… and I've actually transmigrated into the world of Naruto?"
As he finished sorting out the memories of his past life, a voice suddenly echoed in his mind:
[First contact with extraordinary power detected. Awakening of wisdom. Awakening of talent. You have obtained the Space-Time Gate talent and the Divine Effort talent.]
Immediately after, detailed information regarding the two talents, their abilities, and methods of use flowed into his mind.
At the same time, a mysterious rune successfully condensed within his sea of consciousness.
One resembled a mystical portal, while the other took the form of a dodecahedral crystal, both sitting steadily at the center of his consciousness, standing opposite each other.
"Hiss!"
After some time, as Ethan fully absorbed the information, his eyes lit up. He took a sharp breath and thought excitedly:
"I actually got these talents? This is incredible!"
These two abilities were truly powerful.
[Space-Time Gate Talent] Grants access to a personal space-time transit dimension (initially 10 kilometres in size). Initially, it can only connect to the world of One Piece, allowing Ethan to freely travel between the Naruto and One Piece worlds. Individuals with a favourability of 80 or higher toward Ethan can be bound to the Space-Time Gate, gaining the right to travel freely between the two worlds. Ethan has absolute control over the gate. Bound individuals will never have their favourability drop below 80 and cannot reveal secrets related to the gate without Ethan's permission. Betrayal is impossible—if a bound individual betrays Ethan, all their memories and benefits gained from the Space-Time Gate will be erased.
(Favourability Scale:0-9: Stranger,10-29: Friendly,30-59: Good Friend,60-79: Close Friend,80-89: Trusted Ally,90-99: Lifelong Companion,100: Life-and-Death Partner.)
[Divine Effort Talent] Every action, every instance of training, brings guaranteed progress and improvement. By continuously pushing limits, Ethan can break through barriers and gain higher-level skills, techniques, and even new insights. The more knowledge, skills, and experience he accumulates, the greater the breakthroughs he will achieve.
"Haha! With these two abilities, I finally have a future!"
"Otherwise, with my current weak and sickly body—and my identity as an Uchiha—I don't even know how long I would survive."
However, as Ethan focused on the information before him, his expression suddenly stiffened.
[Ethan Uchiha]
Talent: Space-Time Gate, Divine Effort
Lifespan: 6 months
Chakra Attributes: Water, Wind, Fire, Earth, Yin
Skills:
Uchiha Chakra Refining (1/100, Beginner) Traditional Medicine (2314/10,000, Grandmaster) Health Training (1/5000, Minor Success)
"Six months?!"
Ethan's initial joy quickly faded as his brows furrowed.
"I knew my body was weak in this life, but I didn't expect it to be this bad..."
"If I don't fix this, it won't matter how talented I am—I won't live long enough to grow stronger."
His gaze shifted toward the skills section, where two unexpected abilities caught his eye—Traditional Medicine (Grandmaster) and Health Training (Minor Success).
A realization struck him. These were abilities carried over from his past life!
Before reincarnating, he had been a doctor specializing in traditional medicine, suffering from a terminal illness. He had extended his own life far beyond expectations through medical knowledge and health training, though he still hadn't made it past 30.
"But this... this is already a miracle."
"In my past life, I shouldn't have lived past 20."
Health Training had played a critical role in keeping him alive back then.
And now, he had inherited the knowledge and insights from his past life.
Though it was just knowledge—whether it would be effective in this new body was another matter entirely.
"Let's test whether Health Training works in this world."
With that thought, Ethan immediately stood up and began practicing the techniques ingrained in his memory, carefully following each movement.
His frail body felt exhausted after just one round, leaving him breathless. However, he also felt slightly better.
At first, he wasn't sure if it was just his imagination.
Then—
[You practiced Health Training once. Proficiency +1. Lifespan +1 day.]
"What?!"
Sensing the direct feedback from his Divine Effort talent, Ethan immediately checked his status.
His lifespan had increased from 6 months to 6 months and 1 day.
"It actually works?!"
"If I can gain one extra day every time I train, then as long as I practice daily, I don't have to worry about dying early!"
"Hahh..."
Letting out a long breath, Ethan stretched his sore body, his mind stabilizing.
"The lifespan issue is temporarily solved."
"Next, I need to use my medical expertise—along with the resources available in both worlds—to fully restore my body."
"Only then can I train and grow stronger."
At that moment, another thought crossed Ethan's mind.
His mother, Sarah Uchiha, was also in poor health.
Sarah was a high-ranking elder of the Uchiha clan and a powerful kunoichi—one of the creators of the Izanami technique.
Her condition had worsened significantly in the past six months.
Based on Ethan's past-life medical knowledge, if she didn't receive proper treatment soon, she wouldn't live much longer.
"This is unacceptable!"
If he wanted to change the fate of the Uchiha clan, he needed his mother's support.
Not to mention, if he wanted to explore the One Piece world safely, he needed strong allies. He was too weak to survive there alone.
Luckily, his Space-Time Gate talent allowed him to bind others.
His mother was undoubtedly the best candidate.
"Maybe my cousin, Mia Uchiha, could be bound as well?"
"I can teach my mother the Health Training techniques… but will that be enough?"
"Or should I take her to the One Piece world and find a legendary doctor like Dr. Kureha?"
Either way, he needed to talk to her first.
Taking a deep breath, Ethan walked out of his room and entered the living room.
There, Sarah Uchiha sat, waiting for him.
As soon as she saw him, she turned around with a gentle, loving smile.
"That was quick," she said softly. "Congratulations—you successfully extracted chakra!"
With her keen senses, she had already detected the weak chakra fluctuations from his body.
She was happy for her son.
She knew that, despite his frail body, he had always dreamed of becoming a powerful ninja.
Although she had once opposed it, fearing his body wouldn't handle it, she eventually gave in and taught him the chakra extraction technique.
Now, seeing that he had succeeded, she felt both joy and worry.
Ethan looked at his mother, took a deep breath, and clenched his fists.
"Mom… I have something important to talk to you about."
