There were only three generations of Reincarnations mentioned in the manga or was it in the anime? I guess you can take that from the anime/manga for an idea.

But even without noting those things, The Sage mentioned that when two of the reincarnations ended their fight for real, it'll end, cause that was the whole purpose of it.
