Apocalypse Descends: I Survive by Devouring Metal Until the End

While everyone else scavenges for Systems and goddesses in the apocalypse, Gu Ci finds a broken box that can only eat iron.

It doesn’t talk, act human, or grant him an overpowered cheat.

Feed it an iron nail, and it warns him of a zombie horde.

Feed it a steel plate, and it points him toward a way out.

While the whole world is eating people and fighting over food, he builds humanity’s last line of defense with a girl gifted in music, a combat god, and an angel in white.

Then one day, the box lights up with a star chart.

Humanity’s endgame has only just begun!
