Naruto: Kaleidoscope: the Uchiha's Return

Xiao Shanben leads an enviable life in modern society, and everything is moving in a beautiful direction. However, fate played a huge joke on him. Somehow, he suddenly traveled to the world of Naruto and possessed a 16-year-old boy from the Uchiha family - Uchiha Zen. This boy's parents died when he was young, and he has only one younger brother. At this stage, he only has the chakra capacity of a jounin. When he first realized this time travel, Uchiha Zen (also known as Xiao Shan) was filled with despair. He knows that he will probably never go back to the modern society where he once lived, where there are his memories, traces of his life, as well as his dreams and concerns. What makes him even more frustrated is that there is no system help that often appears in novels. If you want to survive in this crisis-ridden world, you can only rely on yourself. In the future, there will be Uchiha Obito, known as the second Sage of Six Paths, the ghost of the old era, Uchiha Madara, Otsutsuki Kaguya, the goddess of Uma, and Otsutsuki Ishiki, who has mysterious and uncertain factors. Fortunately, Uchiha Obito and Uchiha Madara may turn enemies into friends. Just when he was filled with despair, a huge force (chakra) surged out of his eyes, and his vision turned black and he fainted. When he woke up again, he found that he had obtained the Mangekyō Sharingan and awakened his own unique pupil technique "Hachiman God"
