Synopsis

The chapter sees the main characters' group successfully reaching a highly concentrated area of a crystal vein, thanks to an old man's special ability. They discover a peculiar, smooth pillar emitting a faint light and realize it's made of thunder crystal. Upon closer inspection, they suspect it might not be a naturally formed mineral vein but a powerful weapon, prompting them to start mining the surrounding area for resources despite the leader complaining about the time it will take.
