Dark Overlord is not just a simple Undead Skeleton but a Powerful Skeletal Warrior that Ethan nurtured.
Ethan used the maximum number of Undead Cultivation Resources for each major breakthrough for his Undead Avatar.
Thanks to his efforts, not only was Dark Overlord dozens of times more powerful than the other Undead Skeletal Warriors with the same cultivation level, but all his awakened skills were extremely powerful.
Among them, the skill [Undead Synchronicity] was the most powerful one.
Thanks to this skill, all the Undead Skeletons under Dark Overlord's command would gain the same strength as him, and the number of Undead Skeletons in his Undead Legion was limited to one million.
Even though these Undead Skeletal Warriors wouldn't get Dark Overlord's skills, the strength they possessed was comparable to a top sect.
