Chapter 1584: A Great Harvest

Lin Mu cleared out the Immortal Stone mine section by section and made his way inwards. 

Since the growth of the Immortal Stones was according to their grades, Lin Mu had only gathered the Low Grade Immortal Stones by now. The outer radius of the mine would only be composed of low graded immortal stones after all.

In fact, about fifty percent of the Immortal Stone mine was composed of low grade immortal stones. The mid grade immortal stones were at around forty percent while the high grade immortal stones were nine percent. 

The peak grade immortal stones were barely a percent or even less than that.

After all, they would only form around the Source vein of the entire mine. 

Lin Mu had not touched the Peak Grade Immortal Stones other than making the incision as he didn't want to disturb the energy flow of the mine any more. He had already removed the Source Vein, thus the structure of the mine would get a bit unstable.
