Naruto: My System Unifies Seven Worlds

Thrown into not one, but seven parallel Naruto worlds, Xia You, a mere modern student, faces an impossible system quest: unify them all for immortality. How could he, a civilian, conquer a realm of gods and tailed beasts? The answer: Cheat. With his newly acquired Rinnegan and the power to travel through time and space, Xia You has a plan. He'll take Hashirama Senju to witness his beloved brother Tobirama's tragic death. He'll show Madara the betrayal that awaits him. The past's legends will face their painful truths, forcing them to reshape history under his guidance. But will these \"Ninja Gods\" truly bend to the will of an \"immortal\" wielding the future as his weapon, or will his manipulation unleash an even greater catastrophe across the multiversal Shinobi Alliance?
