章節 166: Chapter 166: The Glass Ball

Silver tensed up as the undead looked as if it was about to come through the mirror. She glanced at the headmaster but he was simply taking a sip of his tea, with seemingly no intention of breaking or covering up the mirror.

'Is this a test?' Silver briefly thought as she pulled up her wand one second before the undead reached the mirror.

Then…

"BONK!"

A dull sound came from the mirror as the undead had simply smacked its head against it. It seemed to be trying to get through but nothing happened, it couldn't get through the thin, glass barrier.

A few seconds later the other two undead reached as well, but, they too were unable to do anything to the mirror.
