In 20XX, the global system code-named "Pandora" suddenly arrived, and the blue planet instantly became a giant survival game field. Scarlet channels were torn out of the sky, zombies and mutant beasts poured out like a tide, the city was reduced to ruins, and order was gone. Wu Long, an ordinary office worker, activated the "Desperate Survival System" at the moment of the disaster and became a small but special member among millions of survivors. The system tasks are cold and cruel, and rewards and death follow closely. He must struggle to survive in the end of the world with scarce resources, form a team, conquer dungeons, and compete for survival territory. From a humble survivor who evaded the zombie siege, to a post-apocalyptic powerhouse who can challenge the mutated lord head-on, Wu Long understood through the tempering of blood and fire that there is no restart button in this "game". Only by stepping on the corpses can he protect the people he wants to protect and uncover the ultimate secret behind the system that affects the survival of mankind.
