In 2030, Blue Star, several extraterrestrial meteorites carrying alien biological viruses fell to the earth. The virus raged on the earth. The humans infected by the virus turned into unconscious attacking creatures. The surviving humans named them infected and named the virus. It is the ZTN virus. Since the infected people carry the ZTN virus in their bodies, four-fifths of the world's population have become infected in the near future. Our protagonist Han You steps through the apocalypse, experiencing countless life and death, becoming a strong man, and going from zero to the end of the apocalypse.
