Comment by Unknownagon on Eat & GO - Chapter 12

@Unknownagon yes but I think he meant physical limit like body dont want to move anymore and you fall on your knees from the pain your legs feel

@Unknownagon I'm pretty sure the 'civilians' were there to mine the mana crystals. So, probably very low-ranked/level awakeners with abilities not suited for combat. The dungeon, which is a permanent structure, likely created by an abundance of mana (I could be wrong here) pooling in a specific spot. These dimensional rifts, cracks, gates, whatever you want to call them, open anywhere, even inside dungeons. Once monsters come through, they just settle down and adapt to the world they are in, so they exist everywhere. But in this case, the dungeon was described as weird because there were no monsters. Thus, they let in the 'civilians'. And then the gate appeared in the intermediate sky. The combat team was either already there or called in because a gate appeared. Their job was to cover the mining team's evacuation, right, so they had to either act as a meat shield or kill every single one. And that was going well up until the second 'boss level' Pig appeared. Then Spear Guy was like WTF! How long can we keep this up?! Which was a beautifully done plot prop for the MC to secretly protect everyone, honouring the Old Guardian's request.
