So that other girl has a bland character... hmm... And I thought all your gramps techniques were one hit kill.... looks like other forms of martial arts were mixed in it.... and why the hell would he love them? He just wanted a family...
all of this seems kinda pointless... where is the plot ? is the author just going to turn this into a conflict -->politics --> war --> achievements and recognition --> alies. And full circle again until he becomes some kind ruler ? won't that be kinda boring ? this kind of politics are boring and not well done mostly
