In this era when novels are popular, all kinds of novels are in full bloom. They will form their own unique book souls based on their popularity and other comprehensive influences, but they are all managed by an organization - the Space-Time Administration. One is benefited by it, the other is protected by it, and the two complement each other.
However, due to the sudden rise of time-travel novels, the power of their book-like souls has become increasingly powerful. They begin to wander into the spaces of other novels at will, changing plots, seizing halos, disrupting time and space, and devouring souls. Then novels that have been successfully conquered will no longer exist.
(Due to the different abilities of various types of book souls and the different abilities of each level of system, hosts bound to low-level systems will generally pick book souls with low abilities to upgrade their own systems, and they will also receive corresponding rewards.)
Because organizations like these are large in scale and have strong destructive capabilities, and the "quick travel" branch is particularly prominent, we call it "quick travel virus"...
