"... Mutated spiritual roots are extremely rare, and their cultivation speed is much faster than ordinary spiritual roots. However, most mortals do not have spiritual roots and will never be able to enter the door of immortality." Su Qingyue said, taking out a palm-sized blue crystal stone from the bamboo basket. The surface of the crystal stone was glowing with a soft halo. "This is a spiritual test stone. Tomorrow, you just need to put your hand on it. If the crystal shines, it proves that you have spiritual roots. The brighter the light, the better the quality of the spiritual root."
