In the doomsday era shrouded in haze, the Borderless Corridor has become the only gamble for human beings to continue their lives. It has a strict and diverse screening mechanism, and ordinary people can open the door to the dungeon with their hard work and perseverance. Su Yanci, a top precision instrument restorer, breaks out from the bottom of the hive with the ability of "mechanical resonance", just to exchange for a piece of pure land; Lu Jin, a "space owl", uses "space anchoring" to navigate the black market and is bent on revenge against his family. This pair of sworn enemies were forced to work side by side in a dungeon full of weird rules. They faced each other tit for tat in the game of life and death, and they cooperated tacitly in crises. When human greed and perseverance collide in the dungeon, can the two break through the shackles of the haze and find their own way out in the cruel game of the unbounded corridor?
