A hundred years after the interstellar war ended, the earth has become a dead wasteland covered with alien debris. {Zhao Huang} is a scavenger struggling to survive, collecting interstellar parts in exchange for meager rations. During an exploration deep into the ruins of a battleship, he accidentally picked up a metal fragment engraved with mysterious patterns-the interstellar secret key. This secret key can open the interstellar gate to his new home, but it also makes him a target. The pursuit of interstellar pirates and the coveting of alien survivors followed one after another. Zhao Huang was forced to abandon his stable life of scavenging. He relied on his familiarity with the wasteland and the cunning of the scavengers to get between the forces of all parties. He gathered his partners, solved the mystery of the secret key, and set off a wave of resistance on the ruins. He vowed to use this secret key to open a path to new life for the remaining humans.
