Unknown Mineral Powder

After entering, Wulusi shut the door and looked around.

He saw that this was a highly concealed Storage Warehouse, over a hundred square meters in size. Dark Gray Boxes were piled one after another in the middle.

Walking over, Wulusi touched one and discovered that the box was actually made of metal. But it did not seem to be iron; it was more like lead, and quite thick.
