The dark vertical eye between Mu Chen's brows opened, and dark light shot out. The light looked destructive, and as it flickered, it seemed to pierce through the space.
Nine Nether and the rest were shocked when they saw the vertical eye. Since Mu Chen had obtained this treasure, he had only been using it to help them check on the paths ahead. However, they knew that the abilities to pierce through the space and check on the surroundings were only some of the attributes of the Exterminating Eye.
As Nine Nether and Mu Chen were close, Mu Chen had told her before that the Ancient Treasure Beast had refined its eye into the Exterminating Eye. It had the potential to turn into a sacred object, and it was worth more than all the Quasi-Divine Artifacts that they had obtained. However, there was a large gap between a Quasi-Divine Artifact and a sacred object.
