章節 638: 638. Hidden

The Dark cover spell made use of the natural darkness of the night to cover the figure of the cultivator casting it.

Noah had never relied on it because of that restriction and the limit to the power of its diagram.

However, the appearance of a rank 6 creature in the area that he needed to explore made him reevaluate his priorities.

The modifications on the Dark ray spell had been almost completed, but Noah didn't need it right now.

He could always pick up from where he had left off in the future.

Yet, now he needed something that could allow him to fly unnoticed through the mystical fog.

Of course, he knew that a normal spell wouldn't be able to deceive the natural awareness of a rank 6 beast, but the conditions in that danger zone were quite favorable to him.

The fog naturally affected the perception of the living beings living inside it, and the Fog demons weren't an exception.
