A straight passage about 1.5 meters high and 2 meters wide ends in a square cave with sides of about 10 meters.
The pitch-black, smooth stone walls, and the matte, hard floor, when swept with spiritual power, are clearly made of metal—moreover, it's Primordial Energy Metal reinforced and solidified by an Insect King Level Warrior using Metal System Ability.
In front, and on the left and right walls, a gray-black metal standing cabinet is embedded in each.
At a glance, it could be determined that these are large artifacts from an Outworld Civilization.
The cabinets are about 8 meters wide and just over 2 meters high, with four hinged doors, each with a handle, but no secure locking mechanism like the main doors of a Starship Treasury.
"During the heyday of Huagi Mountain, this was the treasury where the Shield Grasshopper Tribe stored Divine-Given Origin Force Food. The defense was quite solid—behind the metal walls, there were even thicker layers of stone."
