Chen Mo's only goal is to survive and find a way to return to his own time. He must struggle to survive under the cruel laws of the wasteland, using limited knowledge and resources to try to understand the workings of this apocalyptic world, and to look for clues about "time rifts" or any possible legacy technology that can manipulate time. His appearance is like a stone thrown into stagnant water. He not only fights for his own survival, but may also inadvertently disturb the fragile balance of forces in the wasteland, and even reveal the shocking truth about the end of the world. Can he find the elusive rift in time leading back before becoming dust in the wasteland?
