"What is this?" Li Du asked while looking over the document.
Hans did not reply and first said, "Careful, don't ruin it!"
Li Du responded, "This card is very sturdy. What exactly is it? Is it very valuable?"
Hans warned him two more times before gloating. "Yes, this item is very valuable. Our luck is really good. We actually found a black gold abalone harvesting permit."
"Black gold abalone harvesting permit?" Li Du looked over the card and realized what the image of a mollusk on the card was. It turned out that the image was of a black gold abalone.
Black gold abalone was a type of black abalone that was considered extremely rare marine life. From ancient times to today, it had been known as a living fossil by marine biologists.
