"Did they start mining as soon as the Secret Realm opened?"
Song Jun laughed and said, "Yes, each sect brought hundreds, or even immortals. These people are actually helpers brought by the powerhouses. Although Mo Xian Crystal is precious, it's ridiculous to have a Da Luo Venerable mining with his butt in the air every day. Isn't it perfect to leave this to the relatively lower-level immortal disciples?"
Lin Chen's eyes narrowed slightly: "Immortal miners, low-grade labor?"
Song Jun nodded: "Pretty much. It's said that the ink iron ore is incredibly hard, and knives or swords can't damage it. Those below the level of immortals can dig, but the speed is shockingly slow. Only ones with immortal strength can dig with high efficiency."
Lin Chen nodded and fell silent, but his mind had already gone into overdrive.
