At the mouth of the huge cave on the island, Lin Houshou's last Spirit Flag flew out of his hand.
Endless Spirit Light surged, and in the next moment, it turned into a burst of earth light, and the cave disappeared from sight.
"Shiming, the Formation is set up!" Lin Houshou let out a breath of turbid air and, after checking everything thoroughly once more, turned to look at Lin Shiming.
A Superior Grade Spirit Stone Mine was of great importance to the Lin Family. Even a tiny vein of Superior Grade Spirit Stones could produce thousands of them; moreover, this vein was accompanied by a small Intermediate Grade Spirit Stone Mine.
If mined properly, this vein could sustain a hundred-year-old Purple Mansion family, let alone a family like the Lin Family, which had just entered the ranks of Purple Mansion families.
