Shin Yung, a nineteen-year-old university student from Korea, never expected his ordinary life to end in a quiet rented room. When he awakens, he finds himself transmigrated into the Azure Vast Cultivation Realm, a world where strength is everything—where cultivators soar through the skies, shatter mountains, and decide life and death with a glance. Yet fate plays a cruel joke on him. Unlike the protagonists of legends, Shin Yung receives a system that grants no real power at all. Instead, he is bound to the Illusory Effect System—a system that only displays phenomena. It can show the appearance of cultivation realms, manifest terrifying attack effects, project overwhelming defensive pressure, and simulate countless mystical signs… —but none of them carry actual strength. No cultivation base. No physical enhancement. No hidden bloodline. No protection if struck. In other words, Shin Yung is utterly mortal.
