@Grimmycoffee@Mogima They're just his harem, nobody of importance to worry about.
@xLight Remember that Sei in this series has still only just become King of Qin, and still hasn't completed the unification of China. Maybe the author will have him start ramping up after they capture Zhao.
Ryofui's development is really nice to see. I am extremely glad that he still lives, albeit on a journey with his mistresses. My opinion would be much different had it been 300 or so chapters ago, and that just shows how much Ryofui has grown...
