บท 71: Chapter 64 Labyrinth Corridor_3

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.

"Hmm?" Su Yuan's eyes narrowed as he stared ahead.

He saw a large mass of dark green death energy gathering, constantly changing and twisting, eventually forming an energy beam reaching up to the ceiling.

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.
