Bone

Han Sen put the item in his hand. It was around ten centimeters long, and it looked like a bone. But it didn't feel like a bone; it actually felt heavier than metal.

It was obscured in a lot of blood, so it was hard to discern its original appearance. He wiped it all away to reveal its true form.

It was part of a small bone, but it was red and a little purplish. It was different from the Feather's other bones.

Han Sen kept looking around the dead body. Aside from that little bone, the rest were white and of the correct weight. They were a little heavier than a human's, but not like the way the purple one was. That was way heavier.

"What is this?" Han Sen asked Old Cat, holding out the bone.

The cat looked bored, like he could not even muster the energy to answer. "A bone? What else could it be?"
