Summary by u/jeeswag:
Qin:
At the right wing the HSU is getting pushed back and the same thing is happening for the Gakuka on the left. The narration says that usually on a flat ground battle if there is an overwhelming difference in numbers then a battle doesn't happen unless there are unique strategies being employed like with Kanki and his battle against the overwhelming numbers of the Kochou army. In that battle Kanki was leading Kochou from the beginning of the battle. In this case, it's the complete opposite as the Zhao were the ones who fooled the Qin this time with the hidden soldiers and their preparations. The Qin were faced with this situation as soon as the battle began. The Qin soldiers are feeling overwhelmed by the amount of Zhao in front of them and the Zhao soldiers have high morale saying the Qin only has 140,000 and they'll kill those who stepped foot into their land.
Heki's soldier is telling him to pull back but Heki says there's still time to regroup and tries to give orders while getting reports of his troops getting wiped out. The Heki soldiers asked Kanki's army for reinforcements but they don't appear to be moving and the Zhao sees Heki and throw their spears. As Heki tells them to call the Northeastern army that joined them the spears are about to hit and the Najara member knocks them away while yelling "NAJARA!" The Najara are pushing back the Zhao and the Najara member tells Heki that if he doesn't retreat right now it'll cause big trouble. Heki says he can't just leave since it'll hurt the whole army and the Najara says there's no time for that and drags him away while Heki resists.
On the left the Gakuka are struggling to keep up the defense because every spot is calling for reinforcements. His lieutenant is handling one area but they need more soldiers and are not getting any response from Kanki's army. However, 2,000 from the Northeastern army came to their aid and as Mouten gets the report another report comes saying the Zhao broke thru their left wall and he sends the 2,000 there right away. His soldiers are getting taken out 1 by 1 and he thinks that unless they can think of something Riboku couldn't have planned for they won't be able to get out of this and doesn't know what it could be.
On the right Ten is also wondering why the Kanki army isn't responding because once they're thru the Zhao will immediately come for Kanki at HQ. All the HSU is also calling for reinforcements from all sides but are receiving none.
Zhao:
Futei's soldier asks if he's bored and Futei says it's not like that because he surprisingly likes this and the battles they'll win in the future. Riboku says this battle is one where they kept careful track of the enemy's number and kept theirs hidden. Because of this they will simply crush the Qin with numbers just like this and Riboku tells Kanki there's no way out.
Qin:
Kanki is receiving reports that each side is asking for reinforcements and that it'll be really bad if they don't get help. Kanki is really nonchalant about it and when Marron asks why he's not sending any help Kanki says he has no reason. Marron says it's not time to say stuff like that because once those armies are done they'll be done for to which Kanki says to chill out because this battle just got started.
On the right the HSU is trying to fight with a smaller number of cavalry and infantry. Denei sees Shin looking out into the distance and wonders what he's doing standing still at a spot like that when he's usually right in the front of the fray. Shin says it's really dangerous because the fire is going out and if it keeps going like this it'll be completely out. He says he has to somehow light the fire and looks for a spot where he can do that. As he looks around he says he found a spot and calls for the Captain's Emergency Call Flag to be drawn up. As his soldier starts to yell out Shin calls out louder to tell the HSU to listen up. He tells them starting right now they are to break away from their fight and they will leave their role as the wall of the right wing. Everyone is shocked and Ten freaks out asking what Shin's up to
SHIN IS GONNA MOVE OMDS
