The Mortal Cage: A Passage Through the Ruins of Delusion

The walls are breathing. At seven hertz, a signal begins to pulse beneath the city. It passes through concrete, rain, and bone. Qing Heng, a clinician trained to distrust impossible explanations, detects the same rhythm inside a terrified patient's body. Gui Tang remembers what the system tries to erase. Their search leads toward a cage built not from iron, but from measurement, certainty, and the quiet surrender of human choice. The Mortal Cage is Volume I of The Hollow Cage, a long-form philosophical cultivation fantasy about memory, mortality, resistance, and the stubborn human need to remain human. This first volume contains 288 chapters and approximately 603,000 English words.
