Doomsday: I Rely on Time Loop to Save the World

My name is Yu Changnian, I... May be dead... The moment he was knocked down by a zombie, the pain caused by the bite was transmitted from the whole body to the brain. It hurt! I'm going to become a zombie... "No! We can't die like this! I still have things I must do!" … "Beep——" Yu Changnian opened his eyes and found that he had returned to the zombie outbreak for seven days. "I'm back! God helps me! With the time loop, I can definitely save the world!"
