The group found one one of the uses for the mana extracted, but that wasn't enough. They had to keep going, but ten of those guards were on the side of the corridor. Other groups of ten seemed to be moving around and patrolling while they watched the cargo being moved to trucks… it was only obvious that a place that massive would have hundreds of guards.
Everyone looked at Rain and waited for his orders. They hadn't been found until now, but they couldn't relax or do things half-assedly. Rain looked around using Magic Eyes in order to find anything like a barrier, or that could track him, but he didn't find anything. Still, his senses were warning him to keep his guard up.
In the distance, Rain could see the massive cannon standing upward like usual. It was only obvious that the massive boulder they used hadn't caused any damage, but confirming that was still a bit depressive.
