Simultaneous Transmigration: Everyone Else Died

After transmigrating into the Naruto world, Uchiha Roku finds himself burdened with mediocre talent and no cheats—no system, no wise old master. As the shadow of the Third Great Ninja War looms, he grows increasingly anxious about his survival in Konoha. Just as he decides to flee the village and escape the coming storm, he stumbles into a mysterious void and discovers a staggering truth: he has also transmigrated into other worlds simultaneously. By fulfilling the unfinished wishes of those other selves, he can inherit their legacies—sharing their memories, stacking their talents, and amplifying his power without limit. With countless versions of himself as his foundation and countless worlds as his fuel, Uchiha Roku rises step by step, transcending all boundaries and ascending to the absolute peak.
