Chapter 1: Parallel Ninja World, Given Rinnegan at the Start
First year of Konoha.
On the Hokage Rock, Lux looked down at the village of Konoha being built and was stunned.
There was no doubt that he had indeed travelled through time!
And what he had crossed wasn't the ordinary Naruto world, but a space-time matrix composed of seven parallel Naruto worlds.
Each Naruto world was the same as the normal space and time, only the time point was different.
The main mission issued by this system was:
[Choose a power in each space and time to unify the ninja world and ensure that there will be no split within twenty years after unification]
[After completing the main mission, the host himself can immediately become immortal and live forever]
Good news: Lux has a system, and it seems very beneficial.
Bad news: The system's main mission is not easy to complete and is difficult to achieve.
This is the Naruto world!
