The young woman doctor told her she was researching a new drug that might cure her illness. From then on, Jiang Yu had hope for life. Five years later, on her twentieth birthday, Jiang Yu was cured. But fate played a cruel joke: on the day she was discharged, she died in a bizarre car accident. Her overwhelming resentment bound her to a doomsday survival System. For every day she survived in the apocalypse, she could exchange it for one day of life in the real world. For herself and her family, Jiang Yu fought with all her might to survive the apocalypse.
