Han Sen could not wrap his head around it, which was disappointing to him.
He thought the rock would be a tangible treasure he could take with him and somehow utilize, but as far as he could tell, it was just a large slab of rock hewn from an even bigger slab of rock. After a three-year investigation of its origin piece, Han Sen had not discovered anything inherently special about it, either. It was just a tough stone, for all the intents and purposes he could fathom.
Not content with what he had found thus far, he decided to dig deeper. And so he did, swinging his shovel in a near-manic fashion.
The little Metal Eater remained there with him, staring. Its cute face suggested it was trying to figure out what Han Sen was doing and what drove him to behave in the way he was.
As long as the little creature did not squeal or bring other members of its family over, Han Sen did not mind its presence there. Perhaps being in its good books would help, even.
