Startled, Mark almost jumped away on reflex and he would've done so if he hadn't recognized the object at first glance.
A 14x7 rectangle with round corners, black in color with a greyish reflective surface. It was an ordinary-looking smartphone, no different from the ones he had been checking a couple of minutes ago. If he hadn't seen it manifest and fall into the box right in front of him he would've thought someone placed it there by mistake.
'Wait...' Squinting his eyes at it, Mark noticed something else about the device. 'Isn't this...'
Mark quickly opened his inventory and checked something. Though it had gotten a little messy after he filled it with all the stuff he looted, it wasn't too difficult for him to find what he had been looking for. Even if he didn't, the confusion he felt at that moment wouldn't have been any less severe.
