In the shadow of the modern city, psychological counselor Levi is haunted by strange hallucinations: the shadow in the mirror has an extra pair of eyes, and an anonymous text message asks "Who are you?" Investigating the patient's suicide case, he discovers an altar to ancient gods hidden underground in the city, uncovering the truth about the "Shadow Realm" - the "nameless shadow" of the ancient gods controls reality through dreams, and the value of human spirituality is at stake. Levi's memory was tampered with, and he gradually suspected that he was a projection of an ancient god. Joining hands with hunter Ella and professor Kane, he fights shadow beasts and explores deep-sea ruins. Under a mental crisis, his memory reverses: allies betray and self-division. In the end, Li Wei faced the ancient god's true form and had to choose "existence" or "nothingness" in the dream of collapse.
