I’m going to make a prediction:
The Qin 6 will be named after Zhao falls, with the new Qin trio’s feats in the final Zhao Campaign qualifying them to become Qin 6 right from the start.
My predictions for the final three members are:
Moubu
Tou
Ousen
Moubu has deep political ties with Shouheikun and he really is Qin’s golden boy right now. Tou is someone who Shouheikun heavily respects and always has. Ousen is still a wildcard but his feat of capturing Gyou is undeniably top tier, they really can’t afford to not make him a GG at this point if they really want to conquer China.
Yo Tan Wa is already the Prime Minister of Qin and a rank above general. Additionally, she’s the King of her own people who has never needed Sei’s permission to wage war. Making her one of the Qin 6 would be like a demotion for her lol. Kanki, I won’t elaborate on for now but I doubt he makes it past the Zhao campaign.
So yeah. Ousen, Moubu, Tou, Shin, Ouhon, and Mouten will be our new Qin 6.
