Rebirth at the End of the World: I Choose to Save the World

In the last life, a terrible disaster inexplicably swept the world. Unprepared people are like fish on a sword, unable to resist. They lose control of their bodies before they even have a chance to take a look at the beautiful world. The image of my best friend being torn apart by zombies was deeply imprinted in my mind. I thought that if I was reborn, God would fulfill my long-cherished wish to save my best friend. I didn't expect that there would be a more important task waiting for me.
