Kiara continued staring at the floating system message while the faint wind inside the dungeon moved slowly across the barren ground. The air smelled slightly of dust and burnt ether, a quiet reminder of the fierce battle that had ended only minutes ago. Noah stood a short distance away near the landed helicopter, silently waiting for further instructions while the unconscious Kristof Drake remained inside.
The system responded to her question almost immediately.
[Ding! '+' exists for each grade. Didn't host ever wonder why the exchange rate for a gold grade is between 100-500 credits while the silver grade is between 10-50 credits?]
Another notification appeared beneath it.
[Ding! + Grade will occur whenever the item is refined by a blacksmith or through the upgrade stone.]
A third message followed calmly.
[Ding! To upgrade it to the platinum grade, the host needs one more upgrade stone.]
Kiara read the explanation carefully and then slowly nodded.
"I see."
