In a few seconds, the cavern would be completely empty and devoid of Green-Snout Metal moles, leaving the entire place to Lucas. On the other side was a makeshift warehouse carved out by the moles to stash their mining gains.
Without any security measures, it was all open to Lucas. It would be a lie to say that he wasn't tempted to raid the tunnels. Actually, Lucas had already decided to do so.
In less than a minute, the cavern was completely empty, but Lucas still didn't make a move, waiting an extra minute just to be sure, before dashing over to the first tunnel. Based on his inspections, this tunnel had the shortest length, but the metal stored inside was important to him.
