"What on earth is this?" Looking at Leonard Ethan's suddenly enlightened expression as he put down the object, Joan shifted her gaze from the metal piece to Leonard's face.
"I think it's impossible to tell what this is at a glance." "Actually, this thing is pretty easy to guess." Leonard took out a metal block from the table and handed it to Joan, then spoke. "Just rub it with your hand and smell it, and you can probably guess what it is."
"Let me try it—" Joan took the piece of metal, rubbed it with her hand, and then sniffed it near her nose. Her face soon showed an expression of understanding. "I smell a fishy, ocean scent, was this fished out of the sea?"
"That's right, and the time these things were fished out shouldn't have been too long, otherwise the smell of the ocean should have dissipated long ago." Leonard pointed at the dark metal block as he said this.
