Ace was sitting on the beach of the lake while staring at the waterfall. His mind was preoccupied with his family's condition. Although he looked calm in front of Geo, he was in fact very scared.
How did he not? Their sanctuary was damaged, it would not be impossible for the dome of their sanctuary to cave in or it had already been. Such a strong earthquake could overwhelm the dome of every sanctuary.
His hope at the moment could only be placed in the strong structure of his house and the system claimed to be safe capsules to protect them until the army came using Gopher to dig their way to his sanctuary.
Actually, the cave-in of the sanctuary had happened a few times. Every time it happened, many inhabitants of the sanctuary were killed.
Gophers were machines that were used to dig underground. They were used to make tunnels to do rescue missions or building projects.
