After transmigrating to an apocalyptic wasteland, they send me outside the walls to explore. When I return, I haven’t brought back any ancient relics, just a sack of potatoes I grew myself. The guards jeer, “Another worthless scavenger.” Three months later, a tide of demons besieges the high walls, and famine spreads through the city. Standing atop the wall, I dump a cartload of freshly harvested potatoes and pumpkins below. The demons stop and scramble madly for the food. I pick up a megaphone. “Line up! Behave yourselves, and you’ll all get food every day!” Later, I become the keeper of the abyssal demons and start trading food with the nobles inside the high walls.
