The Space-Time Administration's 1584 Squad, with Xuanyao at the vanguard and Fortress, Lingshu, Night Owl, and Spark as its blades, travels through the rifts between countless planes. They have one goal: capture every illegal transmigrator and snuff out the "privileged" sparks of those who use knowledge from other planes to disrupt the balance. From counterfeit poet-immortals in ancient literary circles to System Hosts in fantasy worlds, every mission is carried out to protect one thing: fairness. When transmigrators try to overturn the rules with "foreknowledge" and "cheats," this squad strikes like a blade through the air, forcing imbalanced timelines back onto their proper course and ensuring that each world's history is written only by its own people.
