Eren flashed a wicked smile when he realized that the artifact was a better fit for him than he had initially thought. This artifact alone had made Rog's death worth it for Eren. However, he needed to find something else about him.
"The runestone."
Eren said to himself as he opened Rog's right palm with his hand before forcefully accessing his storage space. In the next moment, all of Rog's possessions had been taken out in front of Eren.
Eren quickly looked through all of Rog's stuff and found what he was looking for right away. He quickly picked up the azure-colored stone in his hand and stared at it carefully.
This azure-colored stone had some runic markings etched on it. When Eren imbued it with his mana sense and wrapped it inside his mana, it sent out a peculiar mana pulse. The act had also erased Rog's residual mana signature from it, making the stone completely Eren's.
