In the Uchiha clan's compound, within a dimly lit room:
"Swish!"
A six-year-old, frail boy named Uchiha kaigen suddenly opened his eyes and sat up straight. This happened at the very moment he successfully extracted his first wisp of chakra.
"This is…"
At that instant, a surge of memories—both familiar and alien—flooded his mind.
For a while, he sat there, digesting the influx of memories while glancing around in shock. He muttered to himself, "Did I transmigrate? I can't believe I just awakened memories of my past life… and now I've been reincarnated into the world of Naruto?"
When kaigen finally sorted through the fragments of his memories, a voice suddenly echoed in his mind:
[First contact with extraordinary power. Innate wisdom awakened. Talents of the Space-Time Gate and Heaven's Diligence have been activated.]
The details of these two talents—how they worked and how to use them—immediately streamed into his consciousness.
Within his spiritual sea, a mysterious rune began to form. It took the shape of an intricate portal and a twelve-sided crystalline figure, both steadily coalescing at the center of his mental space, standing in opposition yet balance.
"Hiss…"
When kaigen finished assimilating the information, his eyes gleamed, and he gasped in excitement. "Did I just get a cheat? This is amazing!"
These two talents were indeed extraordinary:
[Talent: Space-Time Gate]• Grats initial access to a ten-square-meter dimensional portal capable of traversing between the Naruto and One Piece worlds.
• kaigen can freely move between the two worlds.
• Others with an affinity of at least 80 points toward kaigen can be bound to the portal, gaining similar traversal privileges.
• However, kaigen retains ultimate authority. Bound individuals will never drop below 80 affinity points and cannot reveal secrets related to the portal without his permission.
Betrayal is impossible—if someone betrays kaigen , they lose all memories and benefits obtained from the Space-Time Gate
(Affinity levels: 0-9 Stranger, 10-29 Friendly, 30-59 Close Friend, 60-79 Trusted Ally, 80-89 Best Friend, 90-99 Lifelong Companion, 100 Absolute Loyalty).
[Talent: Heaven's Diligence] Every action or cultivation effort yields results and progress.
• Training can reach perfection and even break limits, leading to sudden enlightenment of higher techniques, abilities, ninjutsu, or skills.
• The more knowledge, experience, and preparation before enlightenment, the stronger the resulting technique.
Ha! With these two talents, I finally have hope!" kaigen laughed joyfully, but his smile soon faded. "No, not yet. With my current sickly body and weak condition, I don't even know if I'll survive long enough to use them." Taking a deep breath, he shifted his focus to his skills panel:
[Uchiha kaigen ]
• Talents:Space-Time Gate, Heaven's Diligence
• Lifespan:6 months
• Chakra Attributes:Water, Wind, Fire, Earth, Yin
• Skills:
• Uchiha Chakra Refinement Technique (1/100, Beginner)
• Herbal Medicine (2314/10,000, Mastery)
• Health Cultivation Technique (1/5,000, Beginner)
(Skill proficiency levels: Beginner → Proficient → Mastery → Minor Perfection → Major Perfection → Complete Perfection)
"Six months?"
Seeing his lifespan, kaigen 's excitement drained, replaced by a deep frown.
"I knew this body was weak, but I didn't realize it was this bad…"
He clenched his fists. "I need to fix this first. Otherwise, no matter how powerful my talents are, I won't even have a future to talk about."
Determined, kaigen decided to try the Health Cultivation Technique from his previous life. Though he was a terminally ill medical researcher in his past life, his knowledge of health exercises had allowed him to prolong his lifespan.
He began practicing the technique from memory. After one round, he felt a mix of exhaustion and relief.
[You have practiced the Health Cultivation Technique once. Proficiency +1. Lifespan +1 day.]
"It works?"
Noticing the panel's update and his slightly increased lifespan, kaigen 's face lit up with joy. "Even if it's just one extra day per session, as long as I persist, my lifespan will keep increasing!"
He sighed in relief and muttered, "Lifespan is no longer an immediate issue. Next, I need to use my medical knowledge and resources from both worlds to restore my body completely. Only then can I truly start training to grow stronger!"
However, kaigen 's thoughts soon turned to his mother—Uchiha Jiri, one of the clan's great elders and the creator of the forbidden Sharingan technique, Izanami.
His mother's condition had been deteriorating for years, and without immediate intervention, she might not have long to live either.
"This won't do."
For his future plans to come to fruition, his mother's survival was crucial. Not only was she a pillar of support for the clan, but her help would also be essential for kaigen 's early exploration of the One Piece world.
After all, with his current weak and frail body, surviving in the One Piece world, let alone thriving, seemed almost impossible.
