However, this method of directly summoning the undead from a different location had a fatal flaw-time.
These undead creatures summoned from other planes could only exist for a limited time on the ark continent. This time limit was related to the summoner's own ability and the level of the summoned dark creatures.
In theory, the higher a Summoner's level was, the stronger his magic power would be, and the longer his summoned creatures could stay on the ark continent. The higher the level of a dark creature, the shorter the time it could stay on the ark continent.
