Lin Mo is a struggling delivery boy at the bottom of the "New Era". During a meal delivery, he accidentally awakened to the "door"-shaped mark on his wrist. He gained the ability to travel freely between the post-apocalyptic earth and countless fantasy worlds, and was bound to the "Ten Thousand Realms Delivery System". His mission is simple: take orders, deliver food, and obtain power, knowledge, or treasures from customers in return. From giving a "Spicy Spirit Beast BBQ" to the master cultivator in seclusion in exchange for practicing skills, to giving "Fat House Happy Water" to the master trapped in the magic tower in exchange for elemental affinity, Lin Mo's life has completely changed. The main plot revolves around him using interdimensional resources to rise up in the ruined cities of the real world, gradually uncovering the truth about the fault lines of civilization and the connection between all realms, and eventually grows from an errand boy who passively takes orders to a key figure who connects and affects all heavens and all realms.
