In the Grotto Heaven, a thick layer of medicinal soil, extremely fertile, exuded a black hue along with wafts of medicinal fragrance.
On this medicinal soil, some spirit medicines could be planted to enhance the yield of the herbs.
There were also seeds of some medicinal herbs, rare herbs, and so on, of scarce varieties, many of which were now extinct, either wiped out or monopolized by some major clans. Yet here, there were corresponding herb seeds, or ready-made spirit medicines, spirit fruits, and so forth.
At the central position, there was even an Immortal Qi reception array, which could draw Immortal Qi from the Immortal Realm and refine it directly into Immortal Crystals, known as the Ninth Level Grand Array [Immortal Qi Reception Array].
There was also a Grand Array that could melt numerous Immortal Stones, continuously refining them into World Stones, known as the Ninth Level Grand Array [World Stone Derivation Array].
These two Grand Arrays are both Ninth Level Arrays.
