The smoke of Kannabi Bridge has not yet arrived, but Uchiha Obito's body has been replaced by a modern soul. Dual memories collide in flesh and blood. He must not only fight against the paranoia engraved in the genes of the Uchiha clan, but also use the rationality of modern people to pry a gap in the gears of fate. He saved Kakashi and himself, but refused to become Madara's marionette and returned to Konoha with a serious injury, turning around and stepping into the shadow of Anbu.
When he stopped the dying Shisui in advance, when he became Itachi's secret guide, the bloody fate of Uchiha's annihilation finally deviated from the track in his hands. What his Mangekyo Sharingan awakens is not the power of tearing apart space, but his unique "time and space guardian" - in the broken timeline, he props up a barrier called the future for important people.
Pretending to surrender to Madara's plan, he sneaked into the Akatsuki organization in reverse, trying to use modern thinking to persuade Nagato, and find a path to peace for the ninja world that does not have to rely on the infinite Tsukuyomi; he promoted the reform of Konoha, disintegrated Danzo's roots, and allowed Uchiha to truly integrate into the blood of the village; he traveled through Ryūchi Cave, Mt. Miaomu, and Shiggou Forest, touching the essence of chakra in the inheritance of the three holy places, and during the exploration of the rift in time and space, he glimpsed the coming shadow of the Otsutsuki clan in advance.
When Momoshiki and Jinshiki's star boats pierced the sky of the ninja world, and when the fleet from Otsutsuki's home planet assembled in the depths of the star sea, he was no longer the boy who only knew how to chase Lin. He stands at the junction of the ninja world and the sea of stars, holding in one hand the future of the integration of science and ninjutsu, and in the other hand holding the battle flag of the ninja world alliance, to save Uchi Uchiha Obito from tragedy...
