An accident gave Lin Yi, an ordinary college student, the ability to enter and control dreams freely, and activated the mysterious "dream system." Dreams are no longer just illusory bubbles, but a strange world that is intertwined with reality and has infinite possibilities - a place where human collective subconsciousness is projected, hiding unknown adventures, power and crises.
From his first clumsy lucid dream flight, to exploring the bizarre dream plane under the guidance of the system, fighting mind-devouring nightmares, and getting to know all kinds of dream walkers, Lin Yi discovered that the abilities in dreams can reflect reality, and the secrets deep in dreams are far deeper and grander than he imagined.
When the boundaries between dreams and reality gradually blur, an adventure epic surrounding consciousness and existence begins. Can he control the dream system, grow from an ordinary student to a traveler traveling through thousands of dreams, uncover layers of fog, and protect everything he cherishes?
