It's so Difficult for Me to Be Born in Reincarnation

During the Warring States Period, Uchiha Xinyi, Madara's third younger brother was unparalleled in talent. He was trained as the next leader of the Uchiha clan, but he was dissatisfied with the war and walked the world alone. He retired to the mountains and forests until he died of old age. However, he was accidentally reincarnated by the dirty soil and then reincarnated. When he came back to the ninja world, he was invincible.
