This is one of those story that is good and has a good translator translating it.
It follows our MC who does not belong to any of the ninja villages (him getting thrown with his real body i think) and getting a unique system. Follow as our MC travels the ninja world accepting disciples from all the great villages and getting stronger along the way.
A good story with a good plotline and battle scenes.
