Zombie World Delivery Man

In an ordinary real-world reality, an accidental connection opens to a zombie-infested dimension. Ethan Reed, a food-delivery rider, is unexpectedly transported to this apocalyptic world. He obtains a piece of gold through a food-delivery trade. From then on, Ethan starts traveling back and forth between the two worlds, amassing massive quantities of gold. His huge gold holdings draw protection from a secret organization, launching a cross-temporal operation.
