the six generals are a strong independant force.
currently, ryofui is holding the reins to the kingdom by himself, he would not risk creating something like that, of course the same goes for us.
unfortunately the six great generals would require a constant resupply of soldiers and rations, doing so would put a great strain on our state.
this is a matter that concerns all our policies, not something that should be decided carelessly by the words of one military officer.
