On the way here, besides encountering a large number of undead creatures and occasionally a human team or two, he hadn't found an exit at all...

At this moment, sudden energy fluctuations appeared from the place where the undead mage had exploded in front of him.

The spot on the ceiling illuminated by the energy beam slowly revealed an opening large enough for one person to pass through.

"So the key to the next layer is some of these undead creatures wandering in the maze..."

Su Yuan suddenly understood. No wonder he hadn't found the entrance. There was still this trick.
