Wandering Alone in the Wasteland: My Navigator Comes from the Old World

Radiation, hunger, mutant creatures... This is not all of the wasteland. When all the survivors thought that the "Great Annihilation" was a natural disaster, I got a glimpse of the truth about the end of the world through an old world navigator. They call me "Relic Hunter" and pursue the technology in my hands; the three major forces regard me as a pawn and attempt to annex my foundation. Little did they know, what I really wanted to hunt was the mastermind hiding under the ruins who personally ended civilization!
