Evan had received the Gaze of Monarch skill in the Arora World when some of the soul seals placed on his soul shattered for the first time (Chapter 585).
Due to the destruction of the soul seals, his spiritual power increased greatly and he acquired the Gaze of Monarch skill.
However, even after receiving the skill, he was unable to use it because it was locked, requiring him to create fifty thousand shadow undeads before it could be used.
Evan had always been puzzled as to why he needed fifty thousand shadow undeads to unlock the skill, but now that he had finally unlocked it, he understood the reason.
In order to use the Gaze of Monarch skill, a tremendous amount of spiritual power was required. Due to the sheer volume of spiritual power needed to activate this skill, it was nearly impossible for him to activate this skill using only his own spiritual energy.
