The Advance of the Apocalypse

(No superpowers, no cultivation, no formulaic tropes, no harem, no System. If that bothers you, read with caution.) An artificial virus brings about the apocalypse. There are savage zombies and treacherous hearts. How can an ordinary person survive, lead a group of survivors in building a safe haven, and rebuild human civilization? Disaster may strike at any moment, but the hope of survival will always remain in people's hearts.
