If Hara ends up having shouheikun betray Qin, it's likely right before/during/right after the Chu conquest
We could end up having a tasty Shouheikun, moubu, Ousen trio leading this shit, aiming for a theoretically weakened Qin and surprise surprise shin swoops in, cementing him as the GOAT general... Taking out the three greatest living generals in one dirrrrty play I mean c'mon man
But idk enough of the history or really have the mental power to theorise about this shit
