Yun Che was originally an ordinary young man in the modern world. Due to an accident, he traveled to the world of Naruto and became a ninja apprentice in Konoha Village. Hatake Kakashi: "When will you teach me the simplified version of the Sharingan?" Naruto: "What will teach me the simplified version of the Rasengan?" Yun Che: "Easy to say." Yun Che has a "skill refining system" in his body, which can refine and simplify any ninjutsu, taijutsu, illusion and other skills he has learned, making them more powerful and easier to master.
