So you guys extreme diff guys believe that
1) There's a bunch of guys out there who are essentially Ouki level (martially) that Shin is gonna fight in the future
There already are. Lol.
Renpa, Kaishibou, Kyouen, Ranbihaku and Gaimou from the previous generation for starters. Then there are lurking legends such as Shibashou, Ko Chou
the Guardian Diety, Kou En
the Tiger of Chu etc. Then there are the new generations of other states such as Kou Yoku (who could duel Tou to a stalemate) and Haku Rei and
then there are potential future opponents that can come out the woodwork such as former subordinates of
Great Heaven Chou Sha or
the Military God Gakuki or the other warring states’ new generations.
Besides, who says other Generals actually need to duel Shin in order to oppose him? Shin’s goal was never to be the
strongest General but the
greatest. Individuals such as Rinshoujo and Koshou are considered amongst the greatest Generals in the series without ever having lifted a single weapon. Superior tacticians can still defeat Shin through tactics and strategy due to Shin’s relative inexperience compared to other Generals and his current lack of tactical acumen.
