...............

Sora traveled to the world of the Hokage and became Uchiha Mikasa's son, Uchiha Sora.



At the age of six, when he extracted his first ray of chakra, he awakened his system which gave him two powers: the time-space gate and God rewards for hard work. His first power granted him the power to connect with and travel through the One Piece world.



Sora's strength grew steadily through relentless effort. Drawing upon the memory of traditional Chinese medicine and health-preserving exercises from his previous life, he overcame congenital deficiencies and his mother's soul deficit, thereby extending his life.



By utilizing the resources and cultivation methods from both the Naruto and One Piece worlds, and with the support of the God rewards for hard work, Sora sought to lead the Uchiha clan to a path of eternal dominance.



[You practiced the health-preserving exercises once, proficiency +1, life span +1 day.]



[Your health-preserving exercises broke the limit of perfection, and you realized the secret of longevity.]



[Your Uchiha chakra refining technique broke the limit of perfection, and you realized the source chakra refining technique.]



[Your Conqueror's Haki broke the limit of perfection, and you realized the light of the soul.]
