Activating this Spiritual Emperor's Virtual Battle certainly comes at a cost. In fact, it is high technology from the Martial Realm. Within the Corpse King Palace, there are only twelve Hall Masters who each control one machine, which shows how precious they are!
However, historically, only the absolute geniuses within the Corpse King Palace have been able to initiate the Spiritual Emperor's Virtual Battle. As such, the core of the Spiritual Emperor's Virtual Battle Formation is actually built in the secret treasury of the Corpse King Palace, and all the resources of the entire treasury can be used at will!
What the twelve Hall Masters control are individual sections of the formation. Once activated, resources will be directly called upon from the secret treasury to maintain it!
