Just to know, even a single Heart Clearing with ten thousand years of age is far from enough for Ye Feng at this moment.
Right now, Ye Feng holds five Ancient Slaughter Flame Dragon Pills in his hands, and a single Heart Clearing is simply insufficient to neutralize the power of five Ancient Slaughter Flame Dragon Pills, so Ye Feng and Ling'er continue to hasten the maturation of the Heart Clearing.
Time quickly passes by, and soon ten days have gone by. Ye Feng and Ling'er both show satisfied expressions; they have hastened the maturation of ten Heart Clearings, which have reached the level of ten thousand years.
Using these ten Heart Clearings to refine pills and neutralize the medicinal power of the Ancient Slaughter Flame Dragon Pill, it is completely sufficient now.
However, within the array, the corpse of the Black Death Spirit Clan has not been completely refined; if fully refined, at least fifteen Heart Clearings can be matured to the level of ten thousand years!
