Rebirth of Uchiha: the Opening Rewrites the Night of Genocide

(Invincible + System + Decisive Killing + Behind the Scenes + Not the Holy Mother) The reborn Uchiha Sasuke is only a few years away from the night of genocide! Three generations of hypocrisy, Danzo is ruthless, and the butcher's knife has been sharpened in secret! In times of despair, the [Tiandao rewards those who work hard] system is activated, and all actions increase fivefold! Taijutsu, ninjutsu, pupil arts... When sweat can be quantified, the so-called genius is just a joke! Start by planting the seeds of doubt and tearing Itachi's "Will of Fire" to pieces with your own hands; Hold the dragon's veins in your hand, build the body of an immortal, and overlook the ninja world; Then he recruited Orochimaru, controlled the Five Shadows, and brought the entire world into his own territory! I, Uchiha Sasuke, will give a grand funeral to this decadent era as the mastermind behind the scenes!
