The grains and dust generated from carving the Peak grade Immortal Stone cuboid could be easily used to make peak grade immortal talisman ink.
Lin Mu certainly didn't wish to waste any part of such high quality ingredients thus made sure to use another formation to prevent any dust or granules from being blown away. At the same time, he used a secondary gust array that would suck away the dust and granules into a preserving pouch.
This would ensure that the Peak Grade Immortal stone dust would not lose its immortal Qi and would stay in the best condition.
Even a handful of dust could be sold for several high grade immortal stones after all!
After an hour of careful carving, Lin Mu had hollowed out both the cuboid sections of the Peak Grade Immortal Stone chunk.
~Phew~
"That's the second step done…" Lin Mu wiped away his sweat.
