Starmetal Safe

William set a large foundation with the Earth Element, then used Plant Magic to build a medium storehouse above it, roughly the size of a modern barn. He had to make the storehouse larger than usual, with a large doorway, since Vultures couldn't open doors.

Since the door would be permanently open, he couldn't use Spatial Expansion Arrays to increase the space inside, but he could at least reinforce the structure. Vultures traditionally consumed bones and bone marrow as part of their diets, so William didn't expect them to save many materials anyway.

It was mostly a method to save the excess materials that they weren't able to consume. As the intensity of the Beast Tides grew, the Chasm Guards would eventually have more food than they could eat.

Hmm, these Lightning Scorpion Tails seem to have good Lightning Resistance properties for their rank. I wonder if they'd make for good equipment. I can give some to Gunther and Yuming.
