The end of the world has come, the earth has become a wasteland, zombies are rampant, alien beasts are raging, and humans are struggling to survive in despair. Guo Lin, an ordinary young man, was struggling to survive in this cruel doomsday, but he unexpectedly awakened to a mysterious system.
He originally thought that the system was a life-saving straw, but this system was cold and ruthless, and each task he assigned was more dangerous than the last, seeming to push him towards a dead end. Go to an abandoned research institute full of zombies to obtain mysterious samples, and go deep into the mutated forest that hides deadly crises to find energy cores... Every mission is a test of life and death.
However, Guo Lin refused to admit defeat and relied on his tenacity and wisdom to overcome dangers time and time again under the system's "difficulties". He rose from the ruins, constantly using the points earned from completing tasks to exchange for powerful materials and heaven-defying skills. He gradually grew from a weakling who allowed himself to be slaughtered to a strong man in the apocalyptic world who made zombies and alien beasts fearful.
Let's see how Guo Lin battles wits and courage with the system while fighting his way out of the doomsday situation and rebuilding the light of hope for mankind!
