Upon discovering the resources of these spatial rings, Minos immediately decided to keep one of the Saint-grade medicines for future use.
This medicine didn't have much affinity with any of his family, but if he kept it with him, he could use it to upgrade someone's physique in his army, people who had King-grade Physique and could achieve the Saint grade. Another possibility was to hire a grade-4 alchemist to make pills with it.
But the second medicine was exceptionally compatible with Gloria, who had an innate ability related to mercury, the same as the medicine he had just received.
While moving through the tunnel with his group, he said to Gloria, who already had the Saint-grade medicine in her hands. "Take this. The next time we stop, I want you to eat it and absorb its essence. It will strengthen your innate ability and also help you reach level 82."
