The so-called Nightmare Maze was what ordinary people commonly called being led in circles by ghosts.
It could be a minor matter or a serious one. If they were lucky, they had merely encountered a small Nightmare Wraith Creature that could use deceptive arts to create a few illusions. That would be nothing to worry about.
If they were unlucky, they had encountered a powerful evil spirit with its own Nightmare Realm, which would be rather difficult to deal with.
Yue Wen had yet to encounter a yin creature that could independently control its own Nightmare Realm. The cause of the Nightmare Realm he had encountered at that professor's home remained a mystery. But he had encountered the Meow-Meow Cult Leader and the Fox Demon Lady, who could control Demon Domains. Both were Great Demons whose cultivation rivaled the Dao Realm.
If they had encountered a Nightmare Wraith Creature of that caliber, they were better off killing themselves outright. Perhaps their corpses would look a little prettier.
Of course, Yue Wen still kept Perfected One Nagiko's Sensing Jade Talisman. It was his greatest source of confidence as he ventured through the world, and at a critical moment, it could at least ensure he did not die.
He would not even need Perfected One Nagiko to intervene. If he brought out the Brass Little Sword and ignited its fury, every evil spirit within several miles would flee without a trace.
Although none of these methods was convenient to use regularly, producing any one of them at a critical moment would save his life.
That was why he felt more secure than the others, though he put on quite a panicked expression.
"A Nightmare Maze?" He turned his head back and forth. "What do we do? Brother Xue, can we get out?"
