The remarkable effects of the Ancient Dust Pill left Zhou Chun extremely satisfied, prompting him to invest even more resources and effort in seeking out the Spiritual Medicines required for its refinement.
Speaking of which, it was fortunate that he was refining it in the Great Zhou Kingdom, where gathering resources was highly convenient.
If it were in a place like Jingguo Country, just procuring the blood essence of a fourth-order Magical Beast as the alchemical catalyst would have been a major headache for Zhou Chun.
After all, blood essence is not the ordinary Spirit Blood of a Magical Beast. It's not as simple as heading to the Wasteland Territory, battling a fourth-order Magical Beast, and collecting some fresh blood from its wounds.
But in the Great Zhou Kingdom, though fourth-order Magical Beasts were rare, many major factions kept them in captivity, making it relatively easy to obtain their blood essence.
