Man Zhili, an ordinary office worker, traveled through time and woke up in a desolate ruins full of mutated monsters. He was also bound to a "cheating" system - all survival supplies, from steamed buns and drinking water to self-defense daggers, needed to be exchanged with his own lifespan. As soon as he crossed over, he faced the dual threats of hunger and monsters. He watched helplessly as his life span continued to decrease, but he could only grit his teeth and trade his "life" for survival. In order to survive, he clutched the dagger he had exchanged for his life, dodged and circled in the gray wasteland, fought against the twisted mutants, and struggled to find a glimmer of hope to continue his life in a desperate situation.
