The silver-haired old man's body was already charred black, so his face could not be recognized.
Merlin scanned his body with Mind Power and immediately found a ring on the old man's finger. This silver-haired old man could be an Entrance-level Spell Caster. He might have only constructed one or two Spell Models, so he could have not been that strong. He was powerful probably because he had received some legacy from the Shaman.
Thus, Merlin's aim was the legacy of the ancient Shaman.
Placing the ring in his hand, Merlin's Mind Power directly delved into the ring.
There was a huge space contained in the ring. The silver-haired old man's ring was even better than the one Merlin received from the black-robed old man. The space in it was larger by several folds. Moreover, there were a variety of objects, filling up space in the ring to the brim.
