Duke's gaze swept over the piles of ores.
These were Level 1 and Level 2 Elemental Crystals, not few in number and quite valuable, but not what he truly desired.
Many eyes were on these spoils now, and he couldn't afford to waste time on these ordinary items.
His gaze passed over the piles of ores and rested on a metal door at the deepest part of the platform.
The door wasn't large, entirely cast from a dark silvery metal, with no runes on the surface, but he could feel a faint energy wave emanating from behind it.
He recognized this Magic Metal, a rare metal with natural elemental isolation traits, commonly used for constructing vaults to store high-level Magic Items.
Without hesitation, Duke walked straight to that door.
A crisp cracking sound came from inside the door, like some kind of crystal breaking.
The restriction dissipated, and the door slowly opened inward.
Behind the door was a small space, a secret chamber about ten square meters in size.
