However, it was inevitable. Other than the Hundred-Eyed Rock and the Ash Wolf, which were both low-and middle-tier Gold-rank source beasts, the rest of the source beasts' corpses were all Black Iron and Silver-rank.
Moreover, their talents were very average, and their strength was also very poor.
The probability of source crystals appearing on their bodies was naturally very low.
Other than the poison-attribute source crystals, Lugh also wrapped four thumb-sized poison sacs with a piece of cloth that he pulled from his body.
The crystal and the poison sacs were taken from the body of an ordinary toad. These things were just in line with Lugh's cultivation of Big Mouth.
After putting these things away, Lugh, with the virtue of not wasting them, let the Wyvern directly swallow the usable source beast's corpse.
He also used the Fast Food Digestion of the Wyvern tribe to turn its flesh and blood into its own nutrition and source energy.
