In order to protect his daughter, Levi transformed from an ordinary delivery boy into a doomsday survivor, using his "living map" advantage to find survival resources and hope in the blocked city.

At the same time, he will continue to improve his survival skills and leadership, and eventually become a "delivery man" who delivers "hope" in the city.
