Itachi, Reborn in the World, Defeated Four Battles with One Person

Uchiha Itachi traveled through the Cultivation Continent, unexpectedly acquired the system, passed through all levels, created skills, and finally became a strong man in the reincarnation realm. He returned to the previous world, punched the six-path Uchiha class, kicked six-path Obito, rewrote the outcome of the four battles, and finally became Hokage himself.
