As the apocalypse arrives, humanity's fate is bound together. The protagonist, He Shan, is a survivor. Because humans have overdeveloped Earth's wilderness, the planet faces an energy crisis, awakening the powerful ancient beasts that once roamed the Earth.
To resolve the beast crisis, humanity researches cultivation systems to fight back against the beasts. They absorb the power of heaven and earth to advance through nine realms. Humanity also develops machinery and technology to resist the beasts.
