In a post-apocalyptic wasteland where civilization has collapsed, steel and faith are the only currencies.
The young hunter Lei inherited his father's code name and chariot "Lone Wolf", and searched for the whereabouts of his missing father in the endless wilderness. Traveling with Nia, a highly skilled mechanic, his only clue points to the mysterious "Reconstruction Church" and a key figure named Dr. Franz.
Their journey is full of dangers. Not only do they have to face the terrifying monsters that roam the wasteland, but they also encounter the crazy pursuit of the church's elite troops. In a desperate situation, they unexpectedly meet the legendary hunter Red Wolf and learn a shocking truth: Ray's father and even himself are trapped in a terrifying super soldier program called the "Wolf Series", and the church's "Great Selection" conspiracy is about to bring catastrophe to all mankind. The chariot will roll over lies and ruins, and in the flames and smoke, dark secrets that can overturn the entire wasteland will be revealed.
