The end of the world is coming, monsters are rampant, and humans retreat to the last stronghold. Former agent Wang Yang awakened the "natural disaster devouring" power - killing mutants can plunder their genetic fragments and strengthen himself. He does not travel through time and has no system. He relies solely on his resourcefulness and fighting skills to rise from the ruins step by step. The truth about the fourth disaster emerged on the day: the end of the world is not an accident, but a man-made selection. Wang Yang will use his fists and brain power to break this cruel game and become the final winner.
