We know from Part 1 that he will eventually create an empire with his children and rule for 500 years.
And here he's basically just picking up new knowledge. He will then probably start his conquests again and that brings us to the end of Part 1.
Even if part 3 will focus more on his daughter, it will certainly be part of a campaign of conquest. But I don't expect much if every chapter is just fucked again and the story is basically only told in a few pages at the very end.
