I want something like that :
- Kanki willing to mass killing
- Shin going crazy against that idea
- the other generals being too far / Ousen not caring
- Shin and Kanki fighting
- other guys stopping that
- Shin leaving with his army and going back to Qin capital to talk to Sei
- Sei putting Shin in jail or punishing him an other way
- Riboku come back and fighting
- some time pass
- Shin returning to Zhao to finish the campaign
Yeah Shin is so close to Kanki, he has to make some move.. come face Kanki before Riboku vs Kanki battle.
Unlike last time this is happening on much bigger scale, so we might see big clash, major killings. Kanki this time should be prepared for Shin and if no one intervenes he likely going to kill Shin off.
So someone has to intervene, don't see Ousen going so far for Shin. Ytw is to the far left, maybe Naki will sacrifice himself for Kanki to spare Shin? Maybe Mouten/Ou hon will do something on Ousen name.
This is going to be much serious deal.
Also you see no struggle with Sei himself? Allowing such things he would also be hailed as Mad King?
