Suspension-style ritualistic magic referred to the termination of a ritual according to the Beyonder's judgment. They could finish other matters first before returning to continue the ritual. Even by doing so, it was still possible to gain the desired effects.
This was a technique produced over 1000 years of ritualistic magic development. After all, many high-level ritualistic magic required multiple steps. The duration ranged from an hour to half a day before finishing. It was difficult to ensure that no one disturbed them during the entire process or that there wouldn't be any accidents.
After gaining lessons from various predecessors through blood and tears, gaining feedback through each failure, being able to suspend ritualistic magic became mainstream at the higher levels while it also indirectly affected the lower level rituals.
