After returning to his wooden hut, Chen Mobai immediately took out a medium-grade spirit stone from his storage bag.

Unlike the Immortal Gate spirit stones that Che Yucheng and others repeatedly recharged and used, which only had sixty to seventy percent of their spiritual energy left, the spirit stone Chen Mobai had obtained from the Shenmu Sect was unused and brimming with spiritual energy.

Chen Mobai had a total of six such medium-grade spirit stones.

All were hard-earned rewards from his four years in the Shenmu Sect.
