The Miraculous Use of Divine Extraction

Liu Yan looked at the remaining four sacrificial gemstones, his eyes filled with joy.

The first sacrificial gemstone of the altar of color, the Dark Night Gem, had brought Liu Yan a great harvest.

If Liu Yan comprehended all four sacrificial gemstones, it would bring Liu Yan unimaginable harvests.

Liu Yan spent a whole day comprehending the first gem.

As such, it was impossible for Liu Yan to completely comprehend the remaining four sacrificial gemstones in the remaining two days.
