On New Year's Eve in 2019, an email appeared on everyone's electronic devices around the world. Do you believe in the end of the world? An hour later, all humans on Earth fell into a deep sleep. When I opened my eyes again, the world had quietly changed. Do you believe in the end of the world? Whether you believe it or not, the end of the world has come. Busy living or rushing to die, it's your choice. Welcome to a new era. I am Gu Huan. I was once human. Now, I'm a zombie. I am a unique zombie, which means that I will have a different fate from other zombies. Starting today, I will tell you about my life.
