Cultivators in the later stage of Qi Cultivation can refine one strand of the Five Elements Essence every three to four days.
For cultivators who have given up on the prospect of reaching Foundation Establishment, releasing the spiritual power they've cultivated in exchange for tens of thousands of Good Deed Points is an attractive option.
