------------------------------------------ The MC, Uchiha Kaito, is reincarnated into the Naruto world as the son of Uchiha Jiri—the creator of Izanami—one of the Uchiha clan's ultimate jutsu. At the age of six, during his first attempt to extract chakra, he awakens two extraordinary abilities: Space-Time Gate and Heaven Rewards Diligence. These talents grant him: the power to traverse to the world of One Piece, as well as the road of limitless growth through hard work. Utilizing his memories, Kaito overcomes his congenital weaknesses and his mother’s depleted life force, extending both their lifespans. Then using his knowing of the plot to get all benefits he could get. With the combined resources and training methods of the Naruto and One Piece worlds—and making full use of his Heaven Rewards Diligence talent—Kaito leads the Uchiha clan toward a path of immortality and ultimate dominance. The Uchiha Clan will dominate all. --- (Examples of His Progress:) →[After practicing the Longevity Technique once, your proficiency increases by 1, and your lifespan extends by 1 day.] →[By surpassing the mastery limit of the Longevity Technique, you gained sudden enlightenment and created the Eternal Life Technique.] →[Surpassing the mastery limit of the Uchiha Chakra Refining Technique, you realize the Primal Essence Chakra Refining Method.] →[Breaking the limit of Conqueror's Haki, you gain insight into the Radiance of the Soul.] ---------------------------------------------------------------- Read up to 70 advanced chapters and support me at patreon: patreon.com/_Coreal ----------------------------------------------------------------- Raw: 木叶:重生宇智波的我,双穿海贼 (from faloo.com)

"Mm! Thank you, Mom!"
Uchiha Kaito replied with a warm smile and sat down opposite Uchiha Jiri. His expression turned serious as he looked at his mother earnestly and asked, "Mom, do you trust me?"
"Huh?"
Uchiha Jiri was taken aback at first, but then she smiled gently, reaching out to pat Kaito's head. "What kind of silly question is that? Of course, Mom will always trust you."
"So, is there something you want to tell me? Just say it."
She could sense her son's sincerity. Although she felt a little puzzled, her trust in Kaito was unconditional.
"Thank you, Mom!"
Kaito's face lit up with a smile. Then, under Jiri's astonished gaze, he concentrated his thoughts. A mysterious rune emerged from his forehead and floated before her. He spoke seriously, "Mom, please touch this mark and choose to agree in your heart."
"If you have questions, I'll explain after. Is that okay?"
Rather than explaining everything upfront, he decided to bind his mother to his Space-Time Gate talent first. This would make everything clearer afterward.
As he had predicted, from the moment he saw his mother, his innate talent had confirmed her maximum affinity toward him—a perfect score of 100, she was indeed his mother. She met all the requirements for binding.
No need for unnecessary complications—direct action was best.
"Oh?"
Jiri examined the mysterious mark, then glanced at her son's solemn face. After a moment's thought, she nodded. "Alright!"
The next second, she reached out and touched the mark. Instantly, information surged into her mind. She realized that the mark represented a contract. By binding with Kaito, she would gain immense benefits but also be somewhat tied to him.
Although surprised that her son had gained such a peculiar ability, her trust in him outweighed any doubts. Without hesitation, Uchiha Jiri mentally agreed.
The rune transformed into a streak of light, entering her body and settling in her mind. Within moments, it formed into a gate-shaped symbol in the center of her consciousness. Information about the mark's functions and restrictions flooded her thoughts.
"This… a gate to other worlds?"
Processing the information, Jiri's face shifted to astonishment. She looked at Kaito and asked, "Kaito, what is going on here?"
Kaito smiled slightly and explained, "It's nothing much. When I first successfully extracted chakra, I suddenly awakened this talent. Along with it, I received a mysterious inheritance containing knowledge about our world, this Space-Time Gate ability, and information about other worlds."
"Inheritance? Talent?" Jiri frowned slightly. "Such things are unheard of—it's incredibly mysterious! Kaito, could this be the legendary Sage's inheritance?"
As the elder of the Uchiha clan, Jiri had read numerous historical records, including some detailing the possible existence of the Sage of Six Paths beyond myth.
"A Sage's inheritance? Perhaps." Kaito shrugged noncommittally. His tone turned serious. "Mom, that doesn't matter now. What's important is that this is a huge opportunity for us!"
"The key is to use this inheritance and the resources from other worlds to restore our health, extend our lives, and then consider other matters. Don't you think so?"
"I've received medical knowledge from the inheritance. I can see that your health isn't in great condition either. If we don't address this, nothing else will matter."
"Hmm?"
Hearing this, Jiri's eyes brightened. She asked hopefully, "Does that mean the inheritance has a way to cure your congenital weakness?"
"Yes!" Kaito nodded firmly. "It includes a health preservation technique that can regulate the body and improve health."
"I've already tried it, and it works. Although the effects aren't immediate, with long-term practice, it will definitely prolong life."
"This is what my talent tells me."
"Oh?"
Jiri smiled knowingly, thinking, 'It seems my little Kaito has some secrets, but that's fine. As long as it doesn't harm him, I don't need to dig deeper.'
A mother doesn't need to know every detail—ensuring her child's safety is enough.
"Mom, I'll teach you the health preservation technique now. Try practicing it and see if it helps you!"
Without waiting for her response, Kaito stood up and began demonstrating while explaining each step meticulously.
Jiri didn't reject her son's goodwill. She listened attentively, activating her Sharingan to record his movements precisely.
[You practiced the Health Preservation Technique once: proficiency +1, lifespan +1 day.]
"How was it, Mom? Did you get it all?" Kaito asked eagerly after finishing his demonstration. Sweat glistened on his brow.
"Got it!" Jiri nodded confidently, standing up. "I'll try it once. Watch to see if I'm doing it correctly."
Although she didn't hold high hopes for the technique's effectiveness, she cherished her son's thoughtfulness. If possible, she wanted to live longer—to protect him and ensure his happiness.
Ever since the death of the Second Hokage, Senju Tobirama, the Sarutobi-led faction had increased their hostility toward the Uchiha. Even Uchiha Kagami had fallen victim to their schemes.
Though Jiri lacked concrete evidence, the circumstances surrounding Kagami's death convinced her it was the work of Danzo and his group.
Now, her presence deterred them from outright moves against the clan. But her poor health gave them room for small, covert actions. If she were to die prematurely, the consequences for the Uchiha—and for Kaito—would be dire.
She couldn't allow that to happen.
With such thoughts, Jiri began practicing the technique. For her, it wasn't difficult. Even without the Sharingan, her genius-level intellect made it easy to master.
Under Kaito's watchful eyes, she flawlessly completed the first practice round.
"Mom, you're amazing! You mastered it in one go! How do you feel? Does it work?" Kaito clapped and cheered.
"Ahh!" Jiri exhaled a deep breath, carefully sensing her body's changes. A gentle smile appeared on her face as she turned to Kaito. "It works! The effects aren't dramatic, but I can feel a slight relief from my chronic ailments and a lightness in my body."
"With consistent practice, I believe I can recover some lost vitality and extend my life!"
"My dear Kaito, you truly are my good fortune!"
She wasn't exaggerating. Her precise understanding of her body confirmed the technique's benefits. Combined with proper nutrition and medicinal support, it could heal old wounds, restore vitality, and even reverse some damage.
Realizing this, Jiri felt a rare sense of joy and hope.
