While the Great Hoodwinker was fighting with all his might, Ren Xiaosu had just blocked off a wave of the barbarians' attacks at Position 4 on the other side and retreated to the rear for a short rest.
Meanwhile, the reserve ammo and supplies were finally transported to the front line.
To Ren Xiaosu's surprise, Zero actually came down to Position 4. He asked Zero, "What's the matter?"
"Nothing." Zero said, "I've calculated the remaining quantity of ammo. There shouldn't be much left."
Ren Xiaosu smiled and said, "Are you trying to say that we're going to fail soon? If the defensive position falls, the nanomachines that you have will also be buried here, right?"
