“This... can I exchange it for... Your Knife?”Seeing the middle-aged man’s expression, Yang Tian asked with a smile.
“Of course!”The middle-aged man still looked at the star crystal in his hand and nodded without blinking.
At this moment, the star Crystal had already melted in the middle-aged man’s palm and seeped into his skin.
This middle-aged man didn’t even have the aura of a powerhouse. It seemed that the star crystal was also useful to ordinary humans. Just like the energy of a beast core, it could strengthen the human body.
Actually, this wasn’t strange. Everything in the universe was an energy body, planets were energy bodies, all sorts of materials were energy bodies, and humans were also energy bodies..
It was just that this type of star Crystal had a direct ‘strengthening’effect on living things. It seemed very miraculous, but to humans, it seemed extremely precious.
“How many... such... things... would be enough?”
