There were still some people inside the mechanical fortress who hadn't dared to come out earlier, but Carlotta spotted them one by one and dealt with them accordingly.
During this process, Amelia left the area.
Having learned from Carlotta the locations of the other two mines, she flew off intending to eliminate the Mechanical Fortress personnel there as well, to prevent any escaped miners from spreading news of this place to those at the other two mines.
As for wiping out all the miners, Carlotta hadn't even considered such a thing, she wasn't someone who enjoyed killing without reason.
After Amelia left, Carlotta quickly gathered every visible ore deposit into the Stellar Workshop. Once the exterior ores were collected, she even ventured deeper into the mine to search further.
On the mine's walls, she spotted Tricolor emerald metal, but even placing the Stellar Workshop right beside it, she couldn't absorb the ore into the space.
