Capítulo 506: You Monster

The Nightmare Phantom in the captivity seal turned into black smoke as it dissipated. The test subject Grimm had captured for his experiment ended in failure once again.

Grimm was feeling slightly disappointed. All the test subjects he had captured for the past few days for his experiment had failed.

Grimm did not show the dejection he should have had, instead he maintained his calmness as a sorcerer. After pondering upon the outcome on where he stood for a few moments, Grimm blinked suddenly as he realized something.

A layer of fine black powder had appeared by the seal on the ground. There was such a small amount of powder that it was not easily noticeable, it seemed like merely dust on the ground.

After dipping at the powder with his hand and wiping it with great force, Grimm could be certain that the dust before him was the black powder which had appeared after a Nightmare Phantom had dissipated and not just any ordinary dust.
