Gen Uchiha, a modern social animal, accidentally traveled to the world of Naruto and became an orphan from the Uchiha tribe. He awakened the "Invincible Hokage System" at the beginning, unlocking the side-effect-free Mangekyō Sharingan, full-attribute chakra affinity and perfection-level chakra refining techniques, directly breaking the fate of "Uchiha geniuses need to awaken from grief".
Facing the future genocide and the cruel crisis of the ninja world, he took every step of the way: crushing his peers with perfect scores in three items in the clan test, easily defeating Sasuke in the ninja school, and guiding Itachi out of paranoia; defeating the Iwagakure team in the border mission, and even seeing through Danzo. Using Akatsuki's conspiracy to silence him, he personally sent this "Konoha Cancer" to prison; he formed a tailed beast guard team to help Naruto control the Nine-Tailed Chakra, and teamed up with Shisui and Itachi to seal Kakuzu and Hidan of Akatsuki's organization, gradually dismantling Akatsuki's tailed beast plan.
From the Uchiha orphan who awakened alone to the recognized "Tailed Beast Guardian" of Konoha, Gen relies on the time and space ninjutsu "Micro-blink", the fire escape "Additional Earth Life" and the illusion "Mirror Realm" given by the system. Not only must he embark on the road of invincibility, he must also rewrite the tragedy of the Uchiha genocide, protect Shisui, Itachi and other cherished people, so that Konoha and the ninja world can move towards a new future without regrets.
