Dr. Li Qing, a psychiatrist, encounters a mysterious patient who claims to be a "Creator God" with the ability to manipulate time and space. The patient reveals an astonishing secret: he has constructed an entire microcosm within the confines of a hospital room—a civilization teetering on the brink of extinction after multiple cataclysmic floods. When the patient suddenly dies, Li Qing discovers that every word was terrifyingly real. Now burdened with the patient's legacy, Li Qing must confront an impossible choice: manage the sentient civilization thriving in the microscopic world or risk its exponential growth threatening all of humanity. Armed with newfound god-like authority, Li Qing commands the microcosm's inhabitants, assigning them roles within a mobile shelter—some as neural controllers navigating their vessel through the cosmos, others as biological engines powering its movement. As Li Qing observes the civilization's rapid evolution from single-celled organisms to complex fish-like beings, the boundaries between creator and creation blur. In this bottle universe, the line separating man and god, reality and illusion, becomes increasingly uncertain.
